PLEASE HELP! Listbox Items Retrieval

[behbeh]

Hi!
I'm new to JavaScript and I have been painstakingly searching for info on how to grab all the items (values) in a listbox. The issue is that I need ALL the values; I'm using a calendar control's click event to populate days selected into a listbox. On form submit, I need to grab all of the dates in the listbox...most likely they will not be selected...it's just a 'container' to hold the values (add and remove dates).
If anyone can help me I'd GREATLY appreciate it!!!!

As far as I know there is no one line code which will give you the values of all items in a list box. You have to loop through all the items and get the values of individual items in some temporary variable.

var strValues = '';
var strText = ''
for var i=0, i<document.formname.lstboxname.options.length;i++
{
strValues += document.formname.lstboxname.options.value + 'some delimeter';
//strValues += document.formname.lstboxname.options.text + 'some delimeter';
}
If you want to get the item descriptions which are displayed in the listbox then you can use &quot;text&quot; instead of &quot;value&quot;

got bit by the i bug Not everything you type is understanding to others! Think about that before getting upset with a wrong answer to your question.

if you want to access all of the values in a listbox once the form is submitted, and you don't care which (if any) of the values the user had selected (i.e., a container as you described), consider automatically selecting every value as the form is submitted. that way, all values will be available in the Request.Form object on your next page. i had same situation where i wasn't getting all of the values in a listbox and realized they must all be selected to be passed along.

function selectAllOptions(obj) {
for (var i=0; i<obj.options.length; i++) {
obj.options.selected = true;
}
}

function submitIt(theForm) {
selectAllOptions(theForm.myListBox);
theForm.submit();
}

<form name=&quot;frmMain&quot; method=&quot;post&quot; onSubmit=&quot;submitIt(this);&quot;>
... your form stuff ...
</form>



(p.s., what is up with the automatic italics?)

Thanks!!!!!!!
I was able to make it work (with the help of a hidden input box) once I selected all of the options

Thanks again!
