How do I call javascript from asp.net button click?

Question

I'm working on asp.net and want to execute following javascript code. I'm using VS2010.

   <title></title>
<script type="text/javascript">
    function myClosure() {
        var canyousee = "here I'm ";
        return (function theClosure() {
            return { canyouseeIt: canyousee ? "yes" : "no" };
        });
    }
    var closure = myClosure();
    closure().canyouseeIt;
</script>
</head>

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="myClosure();" />
    </div>

How do i execute function myClosure() on button click so that It gives me confirm i.e popup for yes or no ?

Which code I need to put for confirm ?
How can I execute it on Button Click ?

thanks

I hope this can be of some help. I must confess that what you want to achieve is not clear to me.

<title></title>
<script type="text/javascript">
     myClosure=function() {
        var canyousee = "here I'm ";
        return (function () {
            return { canyouseeIt: function(){return confirm (canyousee)}};
        });
    }
</script>
</head>

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="(myClosure())().canyouseeIt()" />
    </div>

<html>
<head>
<script type="text/javascript">
function myClosure(){
          var r=confirm("Press a button!")
        if (r==true)
        {
             alert("You pressed OK!")
             return true;
        }
        else
        {
              alert("You pressed Cancel!");
              return false;
        }

use

onclientclick="javascript:return YourFunction();"

<script> 
function YourFunction() {
//Do your stuff

return true;
}
</script>

If you return true your asp.new onclick event will be called.. If you return false it wont be called..

as you call it, but prevent the post back by return false on

OnClientClick="myClosure();return false;"

I do not know nether understand the rest of your logic, but this is your issue right now.
