Hi.

View the following source code

I've tried it and it worked.)

<html>
<head>
<Script Language="JavaScript">

function checkB()
{
var elements=document.all["chk"];
var num=document.all["chk"].length;
for(i=0;i<num;i++)
{
if(elements.checked == true)
{
document.myForm.method="POST";
document.myForm.action="myASPPage.asp";
document.myForm.submit();
}
}

}
</Script>
</head>
<body>
<Form name="myForm" id="myForm">
<input type=CHECKBOX name="chk" id="chk1" value="chk1">
<input type=CHECKBOX name="chk" id="chk2" value="chk2">
<input type=CHECKBOX name="chk" id="chk3" value="chk3">
<input type=CHECKBOX name="chk" id="chk4" value="chk4">
<input type=button value="Click Me" onclick="checkB()">
</Form>
</body>
</html>
