Huh???

What does the function "checkAll()" supposed to do?
What loop are to referring to?
What value changes to "NO" to perform the same WHAT?

Your request is unclear to me. Need a bit more information as to what you want to accomplish.

ok i will clear u

i have a list box
<select name="select1" onChange="change();" >

<option value="Yes">Yes</option>
<option value="No">No</option>
</select>

Here change() is a function call

<script >

function change()
{
}
</script>

some java Script code above

above change function change all list box value like

<select name="a1">

<option value="Yes">Yes</option>
<option value="No">No</option>
</select>

<select name="a2">

<option value="Yes">Yes</option>
<option value="No">No</option>
</select>

..

..

this is list box may be 1 or more then 1 because its come from database record

same type of example is check box in yahoo mail or gmail when we click single check then all check boxes are checked if we removed check from single box then its remove from all boxes

The only change from original post to the last was:

Code:

<script >

function change()
{
}
</script>

which does nothing.

You request is still unclear to me.

Also ...

same type of example is check box in yahoo mail or gmail when we click single check then all check boxes are checked if we removed check from single box then its remove from all boxes

What checkboxes are to referring to in your postings?

I could make a code change but since I don't understand what the requirement are
the change I could make would probably not be to your liking as it would make no sense!

Do you have some live code to evaluate?
What you have posted does nothing!

JMRKER, been a while bud. I think lovekhan wants a select element that will change all other select elements of the same type when it changes, to the same selection. E.g. a "global" select element:

PHP Code:


<html>

<head>

<style type="text/css">

#masterBox,

#masterBox option { background-color: #000000; color: #ffffff; margin: 0px 0px; padding: 0px 0px; } 

</style>

</head>

<body>

<label for="masterBox">Change all: </label>

<select id="masterBox" onchange="changeAll(this)">

  <option value="0">Yes</option>

  <option value="1">No</option>

</select>

<hr>

<script language="javascript" type="text/javascript">



var numberOfSelects = 3;

var prefix = "a";



function changeAll(master) {

  if (!master) { return; }



  for (i = 1; i <= numberOfSelects; i++) {

  var ele = document.getElementById(prefix+""+i);

    if (ele) {

    ele.selectedIndex = master.selectedIndex;

    }

  }

}



  for (i = 1; i <= numberOfSelects; i++) {

  document.write("<select id=\""+prefix+""+i+"\">\n");

  document.write("  <option value=\"0\">Yes</option>\n");

  document.write("  <option value=\"1\">No</option>\n");

  document.write("</select>\n");

  }



</script>

</body>

</html>

Well, if that is what the OP wants,
you have made it clearer in one post than he/she has done in two!

Thanks JMRKER, I tried. Nobody is great with English grammar or spelling all the time.
