<input name= "checked[]" type= checkbox "value=" "/>"
<input name= "checked[]" type= checkbox "value=" "/>"
<script>
function getchecked ()
{
var obj = Document.getelementsbyname ("checked[]");//This takes checked[]
var L = obj.length;
for (s=0;s<l;s++)
{
alert (obj[s].value);//This checked value will be output by itself.
if (obj.checked)
{
Alert (' This is checked by the Oh ' +obj.value ');
}
}

}

What if you want to use PHP to get the value of a checkbox, you can use the $_post[' checked[] variable name in PHP, the output is an array, we just have to deal with the array.
