I'm creating a POC using google app maker. I plan on using a JS library that has a dependency on Jquery. I've listed JQuery as an "external resource" to start with and added an H1 element on my html with the following code as part of a client script:
$(document).ready(function(){
$("h1").click(function(){
console.log("jquery works");
});
});
When I preview my app and click on the element, nothing is logged. When I inspect the elements, I can see both the Jquery library and the code above, but the event is not triggering when I click on the element. Any suggestions? The ultimate goal is to be able to use https://querybuilder.js.org/ within the app I'm creating.
My best guess is that when you say that you added the code:
$(document).ready(function(){
$("h1").click(function(){
console.log("jquery works");
});
});
to the client script, what you did was created a client script under the SCRIPTS section of App Maker and then added the code there. If that is so, that is why it's not working.
What you need to do is to use client scripting in the widget event handlers. Each widget has event handlers and the HTML widget is not an exception. What I recommend is to add the code to the onAttach event handler of the HTML widget:
}
Also, you can get rid of the document.ready part and just use the code you see in the image above. That should do the trick.
BONUS: If you will be using classes and ids, for it to work you will need to use the allowUnsafeHtml option:
I hope this helps for now. If you need something else, I'll be happy to help you.
I have a simple jquery click event
<script type="text/javascript">
$(function() {
$('#post').click(function() {
alert("test");
});
});
</script>
and a jquery reference defined in the site.master
<script src="<%=ResolveUrl("~/Scripts/jquery-1.3.2.js")%>" type="text/javascript"></script>
I have checked that the script is being resolved correctly, I'm able to see the markup and view the script directly in firebug, so I must be being found. However, I am still getting:
$ is not defined
and none of the jquery works. I've also tried the various variations of this like $(document).ready and jQuery etc.
It's an MVC 2 app on .net 3.5, I'm sure I'm being really dense, everywhere on google says to check the file is referenced correctly, which I have checked and checked again, please advise! :/
That error can only be caused by one of three things:
Your JavaScript file is not being properly loaded into your page
You have a botched version of jQuery. This could happen because someone edited the core file, or a plugin may have overwritten the $ variable.
You have JavaScript running before the page is fully loaded, and as such, before jQuery is fully loaded.
First of all, ensure, what script is call properly, it should looks like
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
and shouldn't have attributes async or defer.
Then you should check the Firebug net panel to see if the file is actually being loaded properly. If not, it will be highlighted red and will say "404" beside it. If the file is loading properly, that means that the issue is number 2.
Make sure all jQuery javascript code is being run inside a code block such as:
$(document).ready(function () {
//your code here
});
This will ensure that your code is being loaded after jQuery has been initialized.
One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described.
Note: If you're loading code which does not require jQuery to run it does not need to be placed inside the jQuery ready handler. That code may be separated using document.readyState.
It could be that you have your script tag called before the jquery script is called.
<script type="text/javascript" src="js/script.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
This results as $ is not defined
Put the jquery.js before your script tag and it will work ;) like so:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript" src="js/script.js"></script>
First you need to make sure that jQuery script is loaded. This could be from a CDN or local on your website. If you don't load this first before trying to use jQuery it will tell you that jQuery is not defined.
<script src="jquery.min.js"></script>
This could be in the HEAD or in the footer of the page, just make sure you load it before you try to call any other jQuery stuff.
Then you need to use one of the two solutions below
(function($){
// your standard jquery code goes here with $ prefix
// best used inside a page with inline code,
// or outside the document ready, enter code here
})(jQuery);
or
jQuery(document).ready(function($){
// standard on load code goes here with $ prefix
// note: the $ is setup inside the anonymous function of the ready command
});
please be aware that many times $(document).ready(function(){//code here}); will not work.
If the jQuery plugin call is next to the </body>, and your script is loaded before that, you should make your code run after window.onload event, like this:
window.onload = function() {
//YOUR JQUERY CODE
}
`
so, your code will run only after the window load, when all assets have been loaded. In that point, the jQuery ($) will be defined.
If you use that:
$(document).ready(function () {
//YOUR JQUERY CODE
});
`
the $ isn't yet defined at this time, because it is called before the jQuery is loaded, and your script will fail on that first line on console.
I just did the same thing and found i had a whole lot of
type="text/javacsript"
So they were loading, but no further hint as to why it wasn't working. Needless to say, proper spelling fixed it.
Use a scripts section in the view and master layout.
Put all your scripts defined in your view inside a Scripts section of the view. This way you can have the master layout load this after all other scripts have been loaded. This is the default setup when starting a new MVC5 web project. Not sure about earlier versions.
Views/Foo/MyView.cshtml:
// The rest of your view code above here.
#section Scripts
{
// Either render the bundle defined with same name in BundleConfig.cs...
#Scripts.Render("~/bundles/myCustomBundle")
// ...or hard code the HTML.
<script src="URL-TO-CUSTOM-JS-FILE"></script>
<script type="text/javascript">
$(document).ready(function () {
// Do your custom javascript for this view here. Will be run after
// loading all the other scripts.
});
</script>
}
Views/Shared/_Layout.cshtml
<html>
<body>
<!-- ... Rest of your layout file here ... -->
#Scripts.Render("~/bundles/jquery")
#Scripts.Render("~/bundles/bootstrap")
#RenderSection("scripts", required: false)
</body>
</html>
Note how the scripts section is rendered last in the master layout file.
It means that your jQuery library has not been loaded yet.
You can move your code after pulling jQuery library.
or you can use something like this
window.onload = function(){
// Your code here
// $(".some-class").html("some html");
};
As stated above, it happens due to the conflict of $ variable.
I resolved this issue by reserving a secondary variable for jQuery with no conflict.
var $j = jQuery.noConflict();
and then use it anywhere
$j( "div" ).hide();
more details can be found here
make sure you really load jquery
this is not jquery - it's the ui!
<script language="JavaScript"
src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js">
</script>
This is a correct script source for jquery:
<script language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
Are you using any other JavaScript libraries? If so, you will probably need to use jQuery in compatibility mode:
http://docs.jquery.com/Using_jQuery_with_Other_Libraries
after some tests i found a fast solution ,
you can add in top of your index page:
<script>
$=jQuery;
</script>
it work very fine :)
I had the same problem and resolved it by using
document.addEventListener('DOMContentLoaded', () => {
// code here
});
I got the same error message when I misspelled the jQuery reference and instead of type="text/javascript" I typed "...javascirpt". ;)
It sounds like jQuery isn't loading properly. Which source/version are you using?
Alternatively, it could a be namespace collision, so try using jQuery explicitly instead of using $. If that works, you may like to use noConflict to ensure the other code that's using $ doesn't break.
That error means that jQuery has not yet loaded on the page. Using $(document).ready(...) or any variant thereof will do no good, as $ is the jQuery function.
Using window.onload should work here. Note that only one function can be assigned to window.onload. To avoid losing the original onload logic, you can decorate the original function like so:
originalOnload = window.onload;
window.onload = function() {
if (originalOnload) {
originalOnload();
}
// YOUR JQUERY
};
This will execute the function that was originally assigned to window.onload, and then will execute // YOUR JQUERY.
See https://en.wikipedia.org/wiki/Decorator_pattern for more detail about the decorator pattern.
I use Url.Content and never have a problem.
<script src="<%= Url.Content ("~/Scripts/jquery-1.4.1.min.js") %>" type="text/javascript"></script>
In the solution it is mentioned -
"One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described."
For avoiding this -
Many JavaScript libraries use $ as a function or variable name, just as jQuery does. In jQuery's case, $ is just an alias for jQuery, so all functionality is available without using $. If we need to use another JavaScript library alongside jQuery, we can return control of $ back to the other library with a call to $.noConflict():
I had this problem once for no apparent reason. It was happenning locally whilst I was running through the aspnet development server. It had been working and I reverted everything to a state where it had previously been working and still it didn't work. I looked in the chrome debugger and the jquery-1.7.1.min.js had loaded without any problems. It was all very confusing. I still don't know what the problem was but closing the browser, closing the development server and then trying again sorted it out.
Just place jquery url on the top of your jquery code
like this--
<script src="<%=ResolveUrl("~/Scripts/jquery-1.3.2.js")%>" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$('#post').click(function() {
alert("test");
});
});
</script>
I had the same problem and it was because my reference to the jQuery.js was not in the tag. Once I switched that, everything started working.

Check the exact path of your jquery file is included.
<script src="assets/plugins/jquery/jquery.min.js"></script>
if you add this on bottom of your page , please all call JS function below this declaration.
Check using this code test ,
<script type="text/javascript">
/***
* Created by dadenew
* Submit email subscription using ajax
* Send email address
* Send controller
* Recive response
*/
$(document).ready(function() { //you can replace $ with Jquery
alert( 'jquery working~!' );
});
Peace!
This is the common issue to resolve this you have to check some point
Include Main Jquery Library
Check Cross-Browser Issue
Add Library on TOP of the jquery code
Check CDNs might be blocked.
Full details are given in this blog click here
I came across same issue, and it resolved by below steps.
The sequence of the scripts should be as per mentioned below
<script src="~/Scripts/jquery-3.3.1.min.js"></script>
<script src="~/Scripts/jquery-ui.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
This sequence was not correct for my code, I corrected this as per the above and it resolved my issue of Jquery not defined.
We have the same problem....but accidentally i checked folder properties and set something...
You have to check the properties of each folders that you're accessing..
right click folder
'permissions' tab
set the folder access :
OWNER: create and delete files
GROUP: access files
OTHERS: access files
I hope that this is the solution......
When using jQuery in asp.net, if you are using a master page and you are loading the jquery source file there, make sure you have the header contentplaceholder after all the jquery script references.
I had a problem where any pages that used that master page would return '$ is not defined' simply because the incorrect order was making the client side code run before the jquery object was created. So make sure you have:
<head runat="server">
<script type="text/javascript" src="Scripts/jquery-VERSION#.js"></script>
<asp:ContentPlaceHolder id="Header" runat="server"></asp:ContentPlaceHolder>
</head>
That way the code will run in order and you will be able to run jQuery code on the child pages.
In my case I was pointing to Google hosted JQuery. It was included properly, but I was on an HTTPS page and calling it via HTTP. Once I fixed the problem (or allowed insecure content), it fired right up.
After tried everything here with no result, I solved the problem simply by moving the script src tag from body to head
I was having this same problem and couldn't figure out what was causing it. I recently converted my HTML files from Japanese to UTF-8, but I didn't do anything with the script files. Somehow jquery-1.10.2.min.js became corrupted in this process (I still have no idea how). Replacing jquery-1.10.2.min.js with the original fixed it.
it appears that if you locate your jquery.js files under the same folder or in some subfolders where your html file is, the Firebug problem is solved. eg if your html is under C:/folder1/, then your js files should be somewhere under C:/folder1/ (or C:/folder1/folder2 etc) as well and addressed accordingly in the html doc. hope this helps.
I have the same issue and no case resolve me the problem. The only thing that works for me, it's put on the of the Site.master file, the next:
<script src="<%= ResolveUrl("~/Scripts/jquery-1.7.1.min.js") %>" type="text/javascript"></script>
<script src="<%= ResolveUrl("~/Scripts/bootstrap/js/bootstrap.min.js") %>" type="text/javascript"></script>
With src="<%= ResolveUrl("")... the load of jQuery in the Content Pages is correct.
Im using the jQuery noConflict method here:
http://drupal.org/node/1058168
Now, both of the following work:
$jq("document").ready(function(){
alert('alert');
});
$("document").ready(function(){
alert('alert');
});
However this does work:
$("document").ready(function(){
$(".view-product-slideshow .pager-num-1 img").css("display","none");
});
But this does not:
$jq("document").ready(function(){
$jq(".view-product-slideshow .pager-num-1 img").css("display","none");
});
Ive used the noConflict method once before and it worked fine. Ive no idea why it would work for the alert but not the CSS change.
My site is here:
http://smartpeopletalkfast.co.uk/pp4/shop/baby-essentials/sleepsuit-plush
Thanks
UPDATE - Ive now removed the extra code from script.js so all thats there is:
//Hide thumnail on product page thats being used as main image
$jq("document").ready(function(){
$jq(".view-product-slideshow .pager-num-1 img").css("display","none");
});
your error is on line 61 of ur script.js:
Uncaught TypeError: Object #
has no method 'smoothDivScroll'
also in that file u should have everything wrapped in the .ready() not every individual thing
Turns out the element I was trying to target with jQuery was itself generated by javascript. Changing my document.ready to window.load fixed this.
When using the noconflict mode of jQuery, you should use this:
jQuery(document).ready(function($){
$(".view-product-slideshow .pager-num-1 img").css("display","none");
});
jQuery is the new $ and you can pass jQuery as $ to your function().
Also, it's document and not "document"
My company has purchased a product that renders an ASP.NET control on the page. This control uses jQuery 1.2.3 and adds a script tag to the page to reference it. The developers of the control will not support use of the control if it modified in any way (including modification to reference a different version of jQuery).
I'm about to start development of my own control and would like to use the features and speed improvements of jQuery 1.3. Both of these controls will need to exist on the same page.
How can I allow the purchased control to use jQuery 1.2.3 and new custom development to use jQuery 1.3? Also out of curiosity, what if we were to use an additional control that needed to reference yet another version of jQuery?
You can achieve this by running your version of jQuery in no-conflict mode. "No conflict" mode is the typical solution to get jQuery working on a page with other frameworks like prototype, and can be also be used here as it essentially namespaces each version of jQuery which you load.
<script src="jQuery1.3.js"></script>
<script>
jq13 = jQuery.noConflict(true);
</script>
<!-- original author's jquery version -->
<script src="jQuery1.2.3.js"></script>
This change will mean that any of the jQuery stuff you want to use will need to be called using jq13 rather than $, e.g.
jq13("#id").hide();
It's not an ideal situation to have the two versions running on the same page, but if you've no alternative, then the above method should allow you to use two differing versions at once.
Also out of curiosity, what if we were to use an additional control
that needed to reference yet another version of jQuery?
If you needed to add another version of jQuery, you could expand on the above:
<script src="jQuery1.3.js"></script>
<script>
jq13 = jQuery.noConflict(true);
</script>
<script src="jQuery1.3.1.js"></script>
<script>
jq131 = jQuery.noConflict(true);
</script>
<!-- original author's jquery version -->
<script src="jQuery1.2.3.js"></script>
The variables jq13 and jq131 would each be used for the version-specific features you require.
It's important that the jQuery used by the original developer is loaded last - the original developer likely wrote their code under the assumption that $() would be using their jQuery version. If you load another version after theirs, the $ will be "grabbed" by the last version you load, which would mean the original developer's code running on the latest library version, rendering the noConflicts somewhat redundant!
As said ConroyP you can do this with jQuery.noConflict but don't forget var when declaring variable.
Like this.
<script src="jQuery1.3.js"></script>
<script>
var jq13 = jQuery.noConflict(true);
</script>
<!-- original author's jquery version -->
<script src="jQuery1.2.3.js"></script>
You can connect all $'s to jq13 by adding (jq13) after function's }). like this
(function($) {
...
})(jq13);
It seems like the order doesn't matter... for example: http://gist.github.com/136686. The console output is at the top and all the versions seem to be in the right places.
make it false to work
var jq16 = $.noConflict(false);
In the second version declare a variable as $.noConflict(true). And use the declared variable in place of $ used in the jquery code. Please check the below code : This code is used after the declaration of second versions of jquery:
<script type="text/javascript">
var jQuery_1_9_1 = $.noConflict(true); function pageLoad(sender, args) {
var $ddl = jQuery_1_9_1("select[name$=drpClassCode]");
var $ddl1 = jQuery_1_9_1("select[name$=drpSubContractors]");
$ddl.select2();
$ddl1.select2();
$ddl.bind("change keyup", function () {
$ddl.fadeIn("slow");
});
$ddl.bind("change keyup", function () {
$ddl1.fadeIn("slow");
});
}
