在更新面板 AJAX asp.net 之后运行脚本

Question

I am running an ajax update panel in my website. The update panel returns some new controls. I would like to set some JavaScript for the controls after they are returned from the ajax call. Is there any way of doing this? Thanks for any help!

Answer 1

tie into the MSAjax Event

function pageLoad(){ } 

this will fire every time the update panel refreshes.. you can do your rebinding / new bindings there

...and yes, that's all you need to do, put that on the page and it will fire.

Update:: [looks like i had the function named incorrectly ( i think it would still work tho) ] it's really that simple if you have a script manager on the page ..

<script> 
   ///<summary>
   ///  This will fire on initial page load, 
   ///  and all subsequent partial page updates made 
   ///  by any update panel on the page
   ///</summary>
   function pageLoad(){ alert('page loaded!') }  
</script>

Answer 2

You could use a Timer with a function that checks if the controls exists every few hundred ms. Once it detects them, apply your script and end the timer.
