JavaScript - User Control JavaScript Function Doesn't Run

Sep 22, 2010

I 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...

Web Forms :: Invoke JavaScript Function From ActiveX Control

Mar 4, 2010

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.

Web User Control With Javascript Used Multiple Times On A Page - How To Make Javascript Functions Point At The Correct Controls

Apr 12, 2010

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.

Web Forms :: Pass Variable As Html Control Through To Javascript Function

Jan 24, 2011

I have a function that gets the position of a control.

[Code]....

All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:

function (getPosition)
{ var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>');
getPos(txtBox1);
}

I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.
