I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
View 2 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
How do I get the width of a control in javascript if it hasn't been set by a css file declaration, a Style declaration, or a skinID.
I have tried control.width, control.getAttribute.width, and I get nothing!
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?

View 1 Replies how to set webform control proprieties in asp.net and ajax control using javascript. I have asp page that has checkBox, TextBox, MaskedEditExtender, and RegularExpressionValidator.
I set the mask for MaskedEditExtender as Mask="(999)999-9999" and I set the ValidationExpression for RegularExpressionValidator as ValidationExpression="d{10}".
I want to change these two properties when user checked the international checkbox to: Mask="999999999999" and as ValidationExpression="d{12}" Using JavaScript without interrupting with server side and when the user unchecked they get previous value so the interaction should be only in the client side.

I have to fullfill a requirement where my activeX control (developed in c#) need to invoke a callback JavaScript function asynchronously (or) synchronously (or) in both ways. I can handle the context using threads. JavaScript:
function handler_1(){ ..... }
myActiveXObject.registerCallBack(handler_1);
Where in ActiveX control, I need a function "registerCallBack" to accept the argument. But I have no clue how to invoke that registered JavaScript function from my ActiveX control. By digging MSDN forum, I found something as script.GetType().InvokeMember("myJSFunctionName", BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public, null, script, null);
the above line throwing me an exception Unknown Name etc. I do have the definition for "myJSFunctionName" in javascript and I got the script object from the document object.
