I am using Kendo-UI's Grid along with the knockout-kendo scripts and I've come across a problem that I think I'm missing something silly for.
I have a few links posted in one of the grid columns, and in that I'm using knockout to set some of the attributes including a data- attribute as so:
<a class="copyBooking" data-bind="attr: { 'data-bookingid': BookingId }">Copy</a>
I also have a small piece of Javascript that is set to run when the link is clicked:
$(".copyBooking").click(function(){
var bookingId = $(this).data("bookingid");
//code to access a function via ajax'
});
All seems fine on the initial load as the code within the Javascript runs and my alert comes back with the expected results. However, when I change pages the in Kendo Grid (I have my data paged to only show 10 results at a time) something stops the Javascript from functioning.
According to the HTML generated in Firebug or it's equivalent in Chrome, the data- attribute is set correctly in the HTML, so I'm no sure if the .click isn't firing correctly or if the data- attribute itself isn't being picked up correctly.
Does anyone have any suggestions?
As the element doesn't exist after you page through your grid. You need to have this function run on the databound event so that after the grid is re-rendered it will be applied to the 'new' dom element.
The other option would be to extend your knockout model of your rows with a function and click-bind to that.
I have event populating my full calendar and I'd like to add an icon to some of the events that meet a certain criteria. For example, my calendar events are representations of work orders that will be added to routes. So if a work order is in a route, I'd like the event that represents that work order to have an icon in the title that signifies that it is part of a route.
I could just change the event's color, but I'd like more than just color. Am I asking too much? Is this possible?
eventRender: function(event, element, calEvent) {
element.find(".fc-event-title").after($("<span class=\"fc-event-icons\"></span>").html("<img src=\"images/on1.jpg\" />"));
}
Sure you can. In eventRender you can look for and manipulate .fc-event-title (mind that some "short" events may not have this markup), or just add a class with an image background, or add a dingbat (bullet here), like:
.fcimg .fc-event-title:before {content: "\025cf\00020";}
You may also do a little modification in the plugin that is in DayEventRenderer.js file goto "daySegHTML" function and in that right after the condition if (!event.allDay && seg.isStart) (that is the start of the making of event div itslef) insert the following statement:
if (event.imgSource != '')
html += "<div><img src='" + event.imgSource + "' style='display:inline;width:2.0em;height:2.0em;margin-bottom:0.5em'></div>";
Note that event.imgSource is not the builtin event property but you have to provide it while providing the event data.
So if you dont provide event.imgSource nothing will get included and if you provide the image source it will automatically add it.
Hope this will resolve the issue :)
I am new to ASP.NET. I made a simple application which performs some of the mathematical operation like addition, subtraction and so on. Now I have many Labels for each output(add, sub, multiply) . Now I want to display label(add output) first and then after 5 second I want to display next label and so on......
Can anyone help me out. Thanks.
First hide all the labels except 'ADD' using
$("#labelId").hide(); \\do this for all the labels except Add label
then
$("#labelAdd").delay(800).show(); \\give the delay as you like in milliseconds
$("#labelSub").delay(800).show();
$("#labelMul").delay(800).show();
Give a reference to jQuery library in head section then,
Put these scripts inside <script> tag inside
$(document).ready(function(){
//above code here.
});
You should definetly read some javascript or I would totally recommend jQuery, jQuery delay and jQuery show. Those are the 3 things you need.
You hide your label with some css visibility:hidden or display:none and then you can show it delayed with .show() from jQuery.
Have you done anything with javascript/jquery so far? need more help?
I have a web page that contains a "div" element. On the page, there is javascript to reference the div: document.getElementById('divId'). This was working fine until another developer redesigned the page to use an ASP master page.
Now, document.getElementById('divId') returns null. It appears that ASP.net prepends some characters to the names of elements within contents forms when you use a master page. How can I know what the id of the div is when the page loads?
Update Allow me to give a specific example to clarify the question: My page had a div with ID divNotice. After changing my page to use a master page, I see when I print the source to the page that renders that the div ID is ctl00_ContentPlaceHolder1_divNotice. My question is, how am I supposed to know what the div ID is going to be when the framework is done with it?
I think that this is what you looking for.
document.getElementById('<%=divNotice.ClientID%>')
to get the ID of your element as appears on the html page use .ClientID
Hope this help.
Dynamically create the javascript using Control.ClientID to determine the calculated ID of div.
document.getElementById('<%= DivControl.ClientID %>')
Or search for the element on the client side using the base ID as a search pattern. See here: A generic way to find ASP.NET ClientIDs with jQuery
I prefer the server side calculation, but if you don't do it often and/or your current design prohibits it, the client side way is a reasonable workaround.
you can check i the element exists by checking if it returns not null
if (document.getElementById('divId') != null) { /* do your stuff*/ }
in other words:
if (document.getElementById('divId')) { /* do your stuff*/ }
now you have edited you orginal question i got it.. i would do something like this:
var arrDivs = document.getElementsByTagName('div'),
strDivName = "divId";
for (i=0;i<=arrDivs.length;i++){
if( arrDivs[i].id.indexOf(strDivName) != -1) {
alert("this is it")
}
}
you can see a demo here:
http://jsfiddle.net/pnHSw/2/
i think you could do it better with a regex.
But this is a pure JS way i don't know ASP.net
edit: i think Aristos solution is much cleaner :P
maybe you can use a descendent selector un css
<div id="wrapperControler">
<controler id="controler"></controler>
</div>
wrapperControler controler{
dosomething;
}
I am refactoring some CSS on a website. I have been working on, and noticed the absence of traditional HTML IDs in the code.
There is heavy use of CssClass='…', or sometimes just class='…', but I can't seem to find a way to say id='…' and not have it swapped out by the server.
Here is an example:
<span id='position_title' runat='server'>Manager</span>
When the response comes back from the server, I get:
<span id='$aspnet$crap$here$position_title'>Manager</span>
Any help here?
Use jQuery to select the element:
$("span[id$='position_title']")....
jQuery's flexible selectors, especially its 'begins with'/'ends with selectors' (the 'end with' selector is shown above, provide a great way around ASP.NET's dom id munge.
rp
The 'crap' placed in front of the id is related to the container(s) of the control and there is no way (as far as I know) to prevent this behavior, other than not putting it in any container.
If you need to refer to the id in script, you can use the ClientID of the control, like so:
<script type="text/javascript">
var theSpan = document.getElementById('<%= position_title.ClientID %>');
</script>
Most of the fixes suggested her are overkill for a very simple problem. Just have separate divs and spans that you target with CSS. Don't target the ASP.NET controls directly if you want to use IDs.
<span id="FooContainer">
<span runat="server" id="Foo" >
......
<span>
</span>
You can embed your CSS within the page, sprinkled with some server tags to overcome the problem. At runtime the code blocks will be replaced with the ASP.NET generated IDs.
For example:
[style type="text/css"]
#<%= AspNetId.ClientID %> {
... styles go here...
}
[/style]
[script type="text/javascript"]
document.getElementById("<%= AspNetId.ClientID %>");
[/script]
You could go a bit further and have some code files that generate CSS too, if you wanted to have your CSS contained within a separate file.
Also, I may be jumping the gun a bit here, but you could use the ASP.NET MVC stuff (not yet officially released as of this writing) which gets away from the Web Forms and gives you total control over the markup generated.
Ok, I guess the jury is out on this one.
#leddt, I already knew that the 'crap' was the containers surrounding it, but I thought maybe Microsoft would have left a backdoor to leave the ID alone. Regenerating CSS files on every use by including ClientIDs would be a horrible idea.
I'm either left with using classes everywhere, or some garbled looking IDs hardcoded in the css.
#Matt Dawdy: There are some great uses for IDs in CSS, primarily when you want to style an element that you know only appears once in either the website or a page, such as a logout button or masthead.
The best thing to do here is give it a unique class name.
You're likely going to have to remove the runat="server" from the span and then place a within the span so you can stylize the span and still have the dynamic internal content.
Not an elegant or easy solution (and it requires a recompile), but it works.
.Net will always replace your id values with some mangled (every so slightly predictable, but still don't count on it) value. Do you really NEED to have that id runat=server? If you don't put in runat=server, then it won't mangle it...
ADDED:
Like leddt said, you can reference the span (or any runat=server with an id) by using ClientID, but I don't think that works in CSS.
But I think that you have a larger problem if your CSS is using ID based selectors. You can't re-use an ID. You can't have multiple items on the same page with the same ID. .Net will complain about that.
So, with that in mind, is your job of refactoring the CSS getting to be a bit larger in scope?
I don't know of a way to stop .NET from mangling the ID, but I can think of a couple ways to work around it:
1 - Nest spans, one with runat="server", one without:
<style type="text/css">
#position_title { // Whatever
}
<span id="position_titleserver" runat="server"><span id="position_title">Manager</span></span>
2 - As Joel Coehoorn suggested, use a unique class name instead. Already using the class for something? Doesn't matter, you can use more than 1! This...
<style type="text/css">
.position_title { font-weight: bold; }
.foo { color: red; }
.bar { font-style: italic; }
</style>
<span id="thiswillbemangled" class="foo bar position_title" runat="server">Manager</span>
...will display this:
Manager
3 - Write a Javascript function to fix the IDs after the page loads
function fixIds()
{
var tagList = document.getElementsByTagName("*");
for(var i=0;i<tagList.length;i++)
{
if(tagList[i].id)
{
if(tagList[i].id.indexOf('$') > -1)
{
var tempArray = tagList[i].id.split("$");
tagList[i].id = tempArray[tempArray.length - 1];
}
}
}
}
If you're fearing classitus, try using an id on a parent or child selector that contains the element that you wish to style. This parent element should NOT have the runat server applied. Simply put, it's a good idea to plan your structural containers to not run code behind (ie. no runat), that way you can access major portions of your application/site using non-altered IDs. If it's too late to do so, add a wrapper div/span or use the class solution as mentioned.
Is there a particular reason that you want the controls to be runat="server"?
If so, I second the use of < asp : Literal > . . .
It should do the job for you as you will still be able to edit the data in code behind.
I usually make my own control that extends WebControl or HtmlGenericControl, and I override ClientID - returning the ID property instead of the generated ClientID. This will cause any transformation that .NET does to the ClientID because of naming containers to be reverted back to the original id that you specified in tag markup. This is great if you are using client side libraries like jQuery and need predictable unique ids, but tough if you rely on viewstate for anything server-side.
If you are accessing the span or whatever tag is giving you problems from the C# or VB code behind, then the runat="server" has to remain and you should use instead <span class="some_class" id="someID">. If you are not accessing the tag in the code behind, then remove the runat="server".
