how to compare each record with previous record in a same list using javascript?

[mary8]

Hi all,

as my below javascript code, i need to compare each id of my actions with previous actions id within that same list, and do something. But how do i do that? please help..

myFormResponse = function(responseXML) {
var product = $(responseXML).find('product');
			var status = $(product).find('status').first().text();
			if (status == "SUCCESS") {
			var actions = $(product).find('productActionsList');
			
				actions.each(function(i, v) {
					var act = $(v).find('actLocationDTO');
					var actLocId = $(act).find("id").text();
					
					//do comparison for each id with previous id
				});
			};

thanks in advanced.

create a variable storing the previous data, and check against it on each iteration.

under var actions....

var previousData="";

Then in the iterator-loop

if (data==previousData){

}

And finally, also inside the loop:

previousData=data;
