.js files

[Mantorok]

Hi all

I want to seperate my client-side validation into a seperate js file,
unfortunately the .js functions have no concept of document.getElementById,
is it possible to have external javascript files referencing page controls?

Thanks
Kev

Hi Kev,

Yes you can define a separate javascript validation file for your
application. By default every .net web application, access the validaiton
file resided in the asp_net_client directory of your wwwroot. But if you want
to write your own js file , you can do that, once you define, all your
validation methods call will forward to that file.

What you have to do is to define a property in the web config file.

<system.web>
<webControls clientScriptsLocation="/script_files/"/>
</system.web>

And now place the WebUIValidation.js in the script_files folder,

I don't understand the initial question, but I'm not sure Wajahat answered
it...

in a .js file, you can do document.getElementById("blah"); just fine...the
script is included in the page and works against that DOM

Perhaps what you are asking is how to get access to ASP.Net ClientIds ?
maybe you have stuff like
document.getElementById('<%=MyControl.ClientID%>'); ??

in this case, no, your .js file doesn't have access to this. The one
solution is in your page create a bunch of js variables:

<script language=JavaScript">
//at bottom of page, or OnLoad event
var username = document.getElementById("<%=UserName.ClientId%>");
....
</script>

and then in your js file, you have access to the "username" javascript
variable...

i tried creating javascript variables and keeping script in separate file. but i get 'list' not defined...thats the name of the variable i defined in the ascx page.
i implement the separate javascript file because i am using 2 instances of the same user control..and it seems that the javascript is working on that last user control that is added.

please let me know if there is a solution to having 2 instances of user control and working with javascript. i have used the 'clientid' to get unique id..but javascript is working with the last added user control
