please explain this code what is label:item.split and all Sure. Please find my comments in blue color in between your code: function (data) { if (data.d.length > 0) { // $.map function is use to translate all items in an array or object to new array of items. response($.map(data.d function (item) { return { // split function split a string into array based on the split char ('/'). Here you take the first element in the array. label: item.split('/')[0] val: item.split('/')[1] } })); } else { response([{ label: 'No Records Found' val: -1 }]); $('#txtSearch').val(''); } } For the above 2 functions use the below urls: http://api.jquery.com/jquery.map/ http://www.w3schools.com/jsref/jsref_split.asp Hope this helps!

it looks like it is success part of jQuery AJAX call. Server returns array of records to ajax call and success part handle it. It is checking if the response has any record if yes then show or else show message. for more info check http://dotnetmentors.com/aspnet/jquery-ajax-with-pagemethod-in-asp-net.aspx
