Selecting all options in a multiple select input

Using PHP

[andytwiz]

Hi,

I'm using PHP to parse returned selected options which means I need to end the select input name with '[]'

This then breaks my javascript which complains about the name ending with [].

(If I remove the [] from the input name the javascript works but then not the PHP).

How do i get around this problem in Javascript?

Cheers

<form name="test_multiple_select_form" method="post">
<select name="test_multiple_select[]" multiple="multiple"><option label="one" value="one">one</option>
<option label="two" value="two">two</option>
</select>
</form>
script type="text/javascript">
<!--
function selectAllList() {
var aSelect = document.test_multiple_select_form.test_multiple_select[];
var aSelectLen = aSelect.length;
for(i = 0; i < aSelectLen; i++) {
  aSelect.options[i].selected = true;
}
}
-->
</script>
<a href="javascript:selectAllList()" title="select all">select all</a>

Replace:
var aSelect = document.test_multiple_select_form.test_multiple_select[];
With:
var aSelect = document.test_multiple_select_form["test_multiple_select[]"];

andytwiz,

You can access it through the form.elements array, like this:

var aSelect = document.test_multiple_select_form.elements[0];

You'll have to change the index, depending on how many inputs are in the form before the <select>.
