Posted By:      Posted Date: September 27, 2010    Points: 0   Category :ASP.Net

Hi all,

How can I adapt the Javascript function below to work with my TextBoxes?

<head id="Head1" runat="server">   
    <title>Untitled Page</title>   
    <script type="text/javascript">   
        function f(ta_id)

>>>How to use javascript function in aspx file?



I have a file util.js and there some funtions in same file.

For example functions name are keyUp, keyDown, isNumeric, isAlphaNumeric

I have used these functions in aspx code behind in a textbox to restrict user that he may not be able to input any special character.

Before, I used the code directly in aspx file but I have do it for different textboxes therefore to avoid much coding in aspx file I created util.js and put all code in this file but how to use these particular functions in aspx file I couldn't find the way.

Anyone have idea. Do share with me.

I used the reference like this:


' Font-Names="Verdana" Font-Size="8pt" Onkeyup= "keyUp(event.keyCode)" Onkeydown="return isAlphaNumeric(event.keyCode);" onpaste="return false;">

SharePoint Blog - Admin web part - newBlogPostOnClient JavaScript function


In the Admin Links web part in a default blog site, there are several links, the last one of which launches Microsoft Word and allows you to manage your posts from the Word blog template.  Cool feature.  But that web part is not configurable and I can't figure out how to duplicate that functionality.  It appears to have 3 GUIDS that are part of the function, part of the last parameter looks like the Posts list GUID, but it is concatenated with another GUID.   I want to either create my own web part or modify the XSL of the page to call the function, but I'm not sure what those other GUID parameters are.  Does anyone know?  The last one seems to be two of the separated by the # character.


Run a javascript function after UpdatePanel.Update()


I thought that adding the javascript within the ContentTemplate would cause it to run every time the UpdatePanel was updated.  For example, I would assume that for the following:

<atlas:UpdatePanel ID="UpdatePanel1" runat="server" Mode="Conditional" >
        Hello from inside the update panel!!!!
        <asp:Button ID="foo" runat="server" OnClick="foo_Click" Text="Click me to postback!" />
        <script type="text/javascript">alert('Javascript, baby!');</script>

 would cause the function alert() to run every time the UpdatePanel returns from the button click.  This is not the case, however.

How do I do this?  My update panel contains a scrolling Div and I

Javascript doesn't work on IE Mobile 6.12 ?

Hi, I wrote a simple asp.net page with few controls and a function in Javascript that make input validation. The javascript function is called on button click event. I use Windows Mobile 6 Classic emulator, and the javascript doesn't work at all.  I saw few posts on this forum saying that IE mobile works just with jscript and doesn't work with javascript. Is it correct ? Is that mean I have to change my javascript code to jscript code ? I always thought they are the same. Is there newer versions of ie mobile that works with javascript ? Thsnks, David
