</select>

<select name="DispIndustryList" class="SearchBySelect5" id="DispIndustryList" style="background-color: #f8fafc; width: 250px; height: 500px;" onchange="setCompanyOptions();" size="180" multiple="multiple">

	{
			var dropdownIndustry = $("#DispIndustryList");
		var dropdownSegment = $("#DispSegmentList");
		var selectedSegment = $("#DispSegmentList option:selected");
	$.each(selectedSegment, function(index, value) {
	
		//here I want to separate the value.
SelectedSeg = ?
SelectedIndustry = ?
	});

	if (selectedSegment == '') {

Just loop thru the selected values

$('#DispSegmentList option:selected').each(function() {
//do whatever here for each selected value.
})

Maybe I am missing something?

Cathal,

my options values are "4,8630"  the first digit is the segment and the second digit is the industry

I need to set those field like this.

SelectedSeg = '4,5'
SelectedIndustry = '8630,3710'

so I can do the filter in the filterIndustry.cfm

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

$('#DispIndustryList option:selected').each(function() {
     SelectedSeg = $(this).val()
     SelectedIndustry = $(this).attr('data-IndustryNumber')
})

Normally I would use the data prop for the custom data attribute but it doesn't seem to work in this scenario

Hold off on this...

SelectedSeg=""
SelectedIndustry=""
$('#DispIndustryList option:selected').each(function() {
    vals = $(this).val()
    vals=vals.split(",")
    SelectedSeg+= "," + vals[0]
    SelectedIndustry += "," + vals[1]
   })
SelectedSeg=SelectedSeg.substring(1)
SelectedIndustry =SelectedIndustry .substring(1)
