Hi,

In my solution i'm having a

Quote:
Scripts/Functionalities/JSFunctions.js

Now in my ASPX page i need to use the function name "ShowAlert()" inside the "JSFunctions.js"

I just drag and drop the URL of JS file inside my ASPX page. But while i call like

<asp:Button ID="butSavetop" runat="server" Text="Save" OnClientclick="ShowAlert();"/>

It Shows error like "Object Expected"

I'm using VS2010. Am i need to change any property of my JS file ??

could you post code of javascript method that you are calling

Solution 2

As srnr noted, attach the handler to OnClientClick, as Button.Click is a server-side event.

Hit F12 in IE to bring up the Dev Tools.
Navigate to the Script tab and see if your JSFunctions.js it s loaded - it should show up in the combo.

If it doesn't, and you're sure the path is right and the file is actually present on disk, check the js itself for errors - there may be some syntax error that could stop it from loading correctly in the browser.

i can see the <script> reference my Aspx page. But still no use.

i have added a break point in my JS file. My Compiler get inside my JS function but not showing up the alert yet.

So your function is getting called? Is there any error message? The browser may be preventing the alert. Did you try another browser?

Solution 3

I just drag and drop the URL of JS file inside my ASPX page
It might not work like that.

Sounds like it is relative path issue. At times, after deployment the path referenced as a source for images, stylesheets, etc is not correctly formed. This leads to no file found at the location referred because of which images don't download or style-sheets does not get applied.
You would need to make sure that the path is correct such that file is found and used.

I would suggest you to use this Tip and resolve the path correctly before setting the source of the file: Resolving Paths in a Multi-Folder WebSite[^]

i'm new to VS2010, but i have used JS in VS2008 for an year.
It didn't behave like that, i always use to drag and drop my script locations. Its works fine in all conditions.

I think the problem is the framework i have changed now. Am i need to set any settings for VS2010 for JS ?
