How to call a specific Javascript from code behind.

Apr 26, 2012 07:14 PM|LINK

Hello!!! I use this javascript.

<script
 language="javascript" type="text/javascript">
function EvalSound(soundobj) {
  var thissound=document.getElementById(soundobj);
  thissound.Play();
}
</script>

and I play the below success wav file

<embed src="success.wav" autostart=false width=1 height=1 id="sound1"
enablejavascript="true">

by clicking the below button

<form>
<input type="button" value="Play Sound" onClick="EvalSound('sound1')">
</form>

I would like to call the EvalSound function from code behind in an IF statement and play the success.wav file
like this
if (condition)
{
 EvalSound('sound1');
} 

How should I call the function to make it work?

Hello again!!!

The code ClientScript.RegisterClientScriptBlock(this.GetType(), "str", "EvalSound('sound1')"); doesn't work.

I just see written on my screen "EvalSound('sound1').

Moreover my condition is not related with a button click, it is related with time.

As an example the if statement looks like this

if (hour = 10)

{

play the sound1

}

I haven't study this http://delicious.com/anupdg/RegisterStartupScript yet

You can use ScriptManager to call js functions from code behind,

Like,
```
if (condition)
{
 ScriptManager.RegisterStartupScript(this.Page, typeof(Page), "EvalSound", "EvalSound('1');", true);
}
else
{
ScriptManager.RegisterStartupScript(this.Page, typeof(Page), "EvalSound", "EvalSound('2');", true);
}
```
