I hope it should not be problem any1 to understand it. Any help ?

Answer 1

Currently you have defined button onclick event , instead of this set onclick event on checkbox.

<input type='checkbox' name="ChkS[]" value='<? echo $rs->id?>' onClick="openPrint();">

Hope this will help you to solve your problem.

Javascript Modification:

var s = "";
function changeval(value) {
    s = value;
}
function openPrint() {
    alert(s);
    window.open("<?= $_SERVER["PHP_SELF"]; ?>?<?=$qstring?>&print=true","","width=1024,height=600,menubar=yes,resizable=yes, scrollbars=yes");
}

HTML Modification:

<input type='checkbox' name="ChkS[]" value='<? echo $rs->id?>' onchange="changeval(this.value)" />

What I have done?

1. Created an Global Variable s .

2. Attached or Bind onchange event on checkbox and set the value of Variable s according.

3. Now, You have variable s with value, you just have to use it in any function.
