Gary!!!! check if the data exist in the dropdown list

Hi,

I need to check if the group number already exist in the parent window drop-down list
before append the data

my code in the child page:

function AddToTheList()
{
		var SelectedSeg=new Array();
		var SelectedGroup=new Array();	
		var dropdownGroup = $("#DispSelectedGroupBox");
		var options="";
		$('#DispGroupList option:selected').each(function() {
    			vals = $(this).val()
    			vals=vals.split(",")

		   options+='<option value="'+vals[0]+','+vals[1]+ '" data-GroupNumber="'+vals[1]+'">'+vals[2]+'</option>';

   		})
		
		   window.opener.$("#DispSelectedGroupBox").append(options);
}

Open in new window

what I need is to check if #DispSelectedGroupBox has the GroupNumber already
before appending the data to it.

so something like this:

function AddToTheList()
{
		var SelectedSeg=new Array();
		var SelectedGroup=new Array();	
		var dropdownGroup = $("#DispSelectedGroupBox");
		var options="";
		$('#DispGroupList option:selected').each(function() {
    			vals = $(this).val()
    			vals=vals.split(",")

		$.each(dropdownGroup, function(index, value) {
				if ($('#DispSelectedGroupBox option[data-GroupNumber=' +vals[1] + ']').length > 0)
		{
					alert("Already filtering on " + vals[1]);
			}
			else {
		  options+='<option value="'+vals[0]+','+vals[1]+ '" data-GroupNumber="'+vals[1]+'">'+vals[2]+'</option>';
			}
				});
   		})
		   window.opener.$("#DispSelectedGroupBox").append(options);
}

Would it not make sense to just replace whatever is there or are there values coming from somewhere else?

no, it shouldn't replace whatever is there.

so something like this maybe.

function AddToTheList()
{
		var SelectedSeg=new Array();
		var SelectedGroup=new Array();	
		var dropdownGroup = $("#DispSelectedGroupBox");
		var selectedGroups = $("#DispSelectedGroupBox option:selected");
		var options="";
		$('#DispGroupList option:selected').each(function() {
    			vals = $(this).val()
    			vals=vals.split(",")

	$.each(selectedGroups, function(index, value) {
		
		if ($('#DispSelectedGroupBox option[data-GroupNumber=' +vals[1] + ']').length > 0)
		{
			alert("Already filtering on " + vals[1]);
			}
			else {
		  options+='<option value="'+vals[0]+','+vals[1]+ '" data-GroupNumber="'+vals[1]+'">'+vals[2]+'</option>';
			}
	});

   		})
		
		   window.opener.$("#DispSelectedGroupBox").append(options);
}
