hi there as per my previous question which got solved here i am facing another problem which is that i am using jQuery's $.each() to bind all the dynamically added elements and i want to validate every element as per their order for eg :- 1st req, 2nd req and then 3rd req but here the request is not being sent in their order for eg:- 2nd element , 1st eement, 4th element and then 3rd and this keeps on goin i jus want to know how can i keep these request in their order. here is my whole jQuery code :-

function update_db(){
           var udata = {};
           var adata = {};
           del_query = new Array();
           var confirm = 0;
           var vouchdt     = $("#dateinfo").val();         
           var a = "1";   
    if ($("#maintable tbody tr").length>0){

            var vendorid = $("#vendorinfo").val();  

        // prepare data to be updated
           $('[id^="dbtr_"]').each(function(index, table){

               var rid                       =  $('th:eq(0)', this).find('input:eq(0)').val();
               var basecatid                 =  $('td:eq(0)', this).find('select:eq(0)').val();
               var subvendorid               =  $('td:eq(0)', this).find('select:eq(0)').val();

Ajax requests are event driven. Therefore, once a request receives its data, the success: function is called.

You can add the received data to an array as it comes back and then wait until the array is filled ( using if(holderArray.length = x){} or something like that ) with all the returned data to complete your task in order.

Pass the order number along to the success portion in a variable and use that to enter in and then grab the data stored in the array.

holderArray[orderNumber] = result;
