这很好用
This works fine
<html>
<head>
<title>
chkbx
</title>
<script>
function ischecked(Id)
{
var chk = document.getElementById(Id);
if(!chk.checked)
{
alert("Please check Terms and Condition "+Id);
return false;
}
else
{
return confirm("Are you sure want to submit "+Id);
}
}
</script>
</head>
<body>
<div id="div1">
<input type="text"/>
<input type="checkbox" id="checkbox1"/>
<input type="button" önclick="return ischecked('checkbox1');" value="click1" />
</div>
<div id="div2">
<input type="text"/>
<input type="checkbox" id="checkbox2"/>
<input type="button" önclick="return ischecked('checkbox2');" value="click2" />
</div>
</body>
</html>
var chk = document.getElementById(objId);
赋予Null值.
在那里，它不能走得更远！.
无论是否选中！
var chk = document.getElementById(objId);
Give Null Value.
There fore it can not go further!.
for either it is checked or not!
