I am updating one of my sites from asp.net with jQuery UI to use master pages.
Here is a snippet of my original code, which works w/out master pages, but not with:
$('#myCancelEventDialog').dialog({
autoOpen: false,
width: 500,
buttons: {
"Cancel This Event": function () { __doPostBack('btnCancel', ''); },
"Do Nothing": function () { $(this).dialog("close"); }
}
});
However, I see what is going on, with the master page chaging the names of the functions, and this code below fixes it for this instance.
$('#myCancelEventDialog').dialog({
autoOpen: false,
width: 500,
buttons: {
"Cancel This Event": function () { __doPostBack('ctl00$ContentPlaceHolder$btnCancel', ''); },
"Do Nothing": function () { $(this).dialog("close"); }
}
});
Notice I have put the 'ctl00$ContentPlaceHolder$' prefix on the btnCancel so that the appropriate callback function is fixed.
From other threads I have read on stackoverflow, there is a better solution than patching up the code one place at a time as I have done above, but haven't quite got it right yet.
What is the general-purpose way to get jQuery UI postback functions to find the right callback function when you are using master pages like in my example above?
A quick fix could be to do the following
$('#myCancelEventDialog').dialog({
autoOpen: false,
width: 500,
buttons: {
"Cancel This Event": function () { __doPostBack("'" + $('[id$=btnvalue]')[0].id + "'", ''); },
"Do Nothing": function () { $(this).dialog("close"); }
}
});
This uses the jQuery endswith selector since the master page now means your control id have prefixes but the ending is the same. This works as long as you dont have duplicate id's dotted around which is what the asp.net team aimed to stop by prefixing nested control id's.
The downside of this is that jQuery has to do more work to find the element as it cannot use the native getElementById.
Another fix would be to upgrade to asp.net 4.0 where you can turn of the prefixing of controls using the clientidmode
You will want to use the ClientID of the control you are after:
__doPostBack('<%= btnCancel.ClientID %>', '');
However, if you use this technique, you will have to enclose your script block inside a div that is exposed to the ASP.Net runtime via the runat attribute.
<div runat="server">
<script type="text/javascript" language="javascript">
//Your Script Here
</script>
</div>

Here is java script section
$(function () {
CKEDITOR.replace('<%=CKEPage.ClientID %>', { filebrowserImageUploadUrl: 'Upload.ashx' });
CKEDITOR.replace('<%=CKETeznote.ClientID %>', { filebrowserImageUploadUrl: 'Upload1.ashx' }));
});
I could to solve the problem by put below code for each CKEditor control :
(CKEditor control ID).FilebrowserImageUploadUrl = "upload.ashx";
There is no need to javascript code anymore.
I am currently using iron-router and this is my very first attempt to try out the Meteor platform. I has been running into issues where most of the jquery libraries failed to initialized properly because the of the way Meteor renders html, $(document).ready() fires before any templates are rendered. I am wondering is there any callbacks from Meteor/iron-router that allows me to replace the jQuery's dom ready?
Also, how should I (easily and properly) handle the live update of the dom elements if some of them are customized by jQuery/javascript?
This is what i am currently doing, i feel like it is very hackish and probably would run into issues if the elements got updated after the initialization.
var jsInitalized = false;
Router.map(function () {
this.route('', {
path: '/',
layoutTemplate: 'default',
after: function(){
if(!jsInitalized){
setTimeout(function(){
$(document).ready( function() { $$$(); });
}, 0);
jsInitalized = true;
}
}
});
}
With Meteor you generally want to think about when a template is ready, not when the dom is ready.
For example, let's say you want to use the jQuery DataTables plugin to add sorting to a table element that's created by a template. You would listen to the template's rendered event and bind the plugin to the dom:
HTML:
<template name="data_table">
<table class="table table-striped" id="tblData">
</table>
</template>
JavaScript:
Template.data_table.rendered = function () {
$('#tblData').dataTable();
};
Now anytime the template is re-rendered (for example, if the data changes), your handler will be called and you can bind the jQuery plugin to the dom again.
This is the general approach. For a complete example (that includes populating the table with rows) see this answer.
Try making a separate .js file, call it rendered.js if you'd like. and then;
Template.layout.rendered = function ()
{
$(document).ready(function(){console.log('ready')});
}
I use template layout, but you can do Template.default.rendered. I hope that helps.
Also take a look at this part of documentation, especially the Template.events; http://docs.meteor.com/#templates_api
I use Meteor v0.8.0 with Iron Router (under Windows 7) and here is how I handle 'DOM ready':
When I want to modify the DOM after a specific template has been rendered:
I use Template.myTemplateName.rendered on the client side :
Template.blog.rendered = function()
{
$('#addPost').click(function()
{
...
});
}
When I want to modify the DOM after any new path has been rendered:
I use Router.onAfterAction, but there seems to be a trick:
Router.onAfterAction(function()
{
setTimeout(function()
{
$('.clickable').click(function()
{
...
});
}, 0);
});
Notice the setTimeout(..., 0), it doesn't work for me otherwise (DOM empty).
Notice that you can use onAfterAction on specific path, but most of the time I think it is redundant with the Template.myTemplateName.rendered method above.
What seems to be missing:
A way to modify the DOM after any template has been rendered.
I need someone to put me through how I can use jquery dialog to ask "Confirm" or "Cancel" validations before submit. I get Microsoft JScript runtime error: Object doesn't support property or method 'dialog' for this on IE9:
<script type="text/javascript">
$(document).ready(function () {
$("#savechanges").click(function () {
$("#dialog").dialog({
modal: true,
autoOpen: false,
buttons: {
"Confirm": function () {
$("#myformid").submit();
},
"Cancel": function () {
$(this).dialog("close");
}
}
});
return false;
});
});
</script>
<div id="dialog"></div>
<p>
<input type="submit" id="savechanges" value="Save changes" />
</p>
If you set autoOpen as false, dialogbox doesn't open when you define it. So you should set it true.
From jQuery-UI docs,
autoOpen
When autoOpen is true the dialog will open automatically when dialog is called.
If false it will stay hidden until .dialog("open") is called on it.
DEMO
There can be multiple reason behind this issue, make use of any debug tool like firebug to check
Use a tool like Firebug for Firefox to verify each JS file is being included.
Make sure there is no other JS on the page that could cause an error.
Verify you have the correct versions of the files downloaded.
I am having no luck in getting a jqueryui dialog to ajax load a form, which inturn submits via ajax.
Everything works upto the point of catching the form that is being submited and instead sending it through an ajax call. Thus the form action is triggered and the browser redirected. The ajax call is never made.
My code is as follows
$(document).ready(function() {
$('.viewOrder').click(function() {
$('#displayOrder').load(this.href, [], function() {
console.log("landed here");
$('#blah').click(function() {
console.log("submiting the form via ajax");
$.ajax({
url: "/ajax/orderupdate",
type: "GET",
data: data,
cache: false,
//success
success: function (data) {
console.log("worked:");
}
});
return false;
});
});
return false;
});
});
.viewOrder is the a href that is ajax loaded. This works fine.
I have read many similar questions on here and it seems load() does not execute scripts that are embeded in the return html, but my return code is pure html no scripts. Any ideas?
IMHO you should try and capture the submit instead of the click, that way you prevent submits done by keyboard aswell, and it might even fix your problem.
The events are bound on page load. At page load the form you are binding the click event does not exist. I use the livequery plugin but they added Live to jquery 4 which you can also use(i had some issues with IE so i went back to livequery)
So load livequery with your scripts http://docs.jquery.com/Plugins/livequery
and change
$('#orderUpdate').submit(function() {
to
$("#orderUpdate").livequery("submit", function() {
right now I have a huge Solution in which we use javascript alerts via RegisterStartupScript for all messages and errors.. We were willing to modify all this to making something similar to the modalPopupExtender, or the extender itself in a way that doesn't require too much effort... I mean, to show a modalpopup on a single page I need to create it on the aspx file, setting the attributes etc... So i'm just asking for Ideas, want to know how you guys deal with this..
I'd probably use jQuery dialog and put the markup and initialization code in a MasterPage, set with autoOpen false and hidden by default. I'd inject code that interacts with the dialog into each page as needed.
<div id="modalDialog" title="Error">
<p id='modalDialogMsg'>An error has occurred.</p>
</div>
<script type="text/javascript">
$(function() {
$('#modalDialog').dialog({
autoOpen: false;
modal: true,
buttons: {
"OK" : function() {
$(this).dialog('close');
}
}
});
});
// You could "objectify" this, but I'll show as a global function
function showError( title, msg )
{
if (!title) {
title = 'Error';
}
if (!msg) {
msg = 'An error occurred.';
}
$('#modalDialogMessage').html(msg);
$('#modalDialog').attr('title',title)
.dialog('open');
}
</script>
Then, in your page you'd inject code that calls showError. Note this would need to be after the script above in order to make sure that the function has been defined. What would spit out would render like:
<script type="text/javascript">
$(function() {
showError('Database connection error', 'There was an error connecting to the database.' )'
});
</script>
Could you not place the modal popup/ modal popup extender into a user a control and embed the user control into each page?
