Im trying to get some checkbox with a specific name
document.getElementsByName("test");
Unfortunatley i cant check if it is checked or not here is the code
for(i=0;i<check.length;i++)
{
if(check[i].checked==true)
{
alert(check[i].value);
}
}
Is somewhere a typo?

Reset to default 3jQuery would be nice for these basic things.
But you aren't using jQuery so:
var check = document.getElementsByName("test");
instead of just
document.getElementsByName("test");
Also, you can remove ==true, so you get:
if(check[i].checked)
Which makes much cleaner code.
Also, are you sure you set the name of the checkboxes to "test" (sometimes people forget these things, like me every time ^^)
jQuery Example
First, download jQuery from http://jquery./
$("input[type=checkbox][name=test]:checked").each(function() {
alert($(this).val());
});
That should do it. If you aren't familar with jQuery, look at this: http://docs.jquery./Tutorials:How_jQuery_Works
Use the following code
<html>
<script type="text/javascript">
function test()
{
if(document.getElementById("chk").checked)
{
alert('Checked');
}
}
</script>
<body>
<input type="checkbox" id="chk">
<input type="button" onclick="test();"></input>
</input>
</body>
</html>
for(i=0;i<check.length;i++)
{
if(check[i].checked==1)
{
alert(check[i].value);
}
}
Try this ?
@streetparade : tell me if this is also not working .... so that i can delete my answer... people didn't like it
