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);
}

Open in new window
