get value from checked checkbox

[robert_gsfame]

I have dynamic checkboxes, so that number of checkboxes appeared depends on users

 

then how can i get the value from checked checkbox

let say i have this

$id is the data that i retrieve from database

<input type="checkboxes" value=<?php echo $id;?>><a href=javascript:void(0) onclick="getvalue()">

 

thx

Loop through them. Check if it's checked, and if so, get the value. Example code:

 

var i = document.getElementById("input"), ic = i.length;
for (var a = 0; a < ic; a++) if (i[a].type == "checkboxes" && i[a].checked) window.alert(i[a].value);

The problem is that if there is more than 1 checked checkbox, then how can i get both values
