javascript - Populate table with variable created from ajax response -

i have table populated data need use run second query. using jquery datatables , functions see allow me grab content table. example grabbing integer out of fourth column , using number run query json response :

var cells = []; var rows = otable.fngetnodes(); for( var i=0;i<rows.length;i++)         {             var grabsku = $j(rows[i]).find('td:eq(3)').text();             grabsku = grabsku.substring(0, 6) + "-0" + grabsku.substring(7, grabsku.length - 4);             s7url = 'http://jsonquery.com/' + grabsku  + '?req=exists,json';                $j.ajax({         url: s7url,         datatype: 'jsonp'         });        } 

then ajax request json returns either 1 or 0 can form correct info depending on returned.

function s7jsonresponse(response)         {         var s7img = sku;         s7img = '<img src="http://imageserver.com/is/image/' + s7img.substring(0, 6) + "-0" + s7img.substring(7, s7img.length - 4) + '">';          x = response["catalogrecord.exists"];                z = x == "0" ? "no img" : s7img;              console.log(z);         } 

console shows me want z variable, either image path or no img. problem getting out of console , table. want happen each response comes in replace td in table z variable. tried put in jsonresponse did not work correctly. how iterate through table, in case (td:eq(2)) , replace each cell variable z query?

need create function ajax can pass row index , url contains data query string arguments. since know cell index , once data returned ajax can call fnupdate using new data , row index within success of ajax

var cells = []; var rows = otable.fngetnodes(); (var = 0; < rows.length; i++) {     var grabsku = $j(rows[i]).find('td:eq(3)').text();     grabsku = grabsku.substring(0, 6) + "-0" + grabsku.substring(7, grabsku.length - 4);     s7url = 'http://jsonquery.com/' + grabsku + '?req=exists,json';     var rowindex = i;     doajax(s7url, rowindex) }    function doajax(url, rowindex) {     $j.ajax({         url: s7url,         datatype: 'jsonp',         success: function(repsonse) {              var s7img = sku;             s7img = '<img src="http://imageserver.com/is/image/' + s7img.substring(0, 6) + "-0" + s7img.substring(7, s7img.length - 4) + '">';             x = response["catalogrecord.exists"];             z = x == "0" ? "no img" : s7img;             console.log(z);         /* fnupdate here using new data , rowindex , know cell index already*/         }        }); }
