Question

I borrowed a piece of code from somewhere, but I don’t understand it. It is kind of ajax call webservice.

function SearchMyStuff() {
$("#tblHouse").hide();
$.ajax({
    type: "POST",
    url: pageName + "SearchMyStuff",
    data: "{'oParams':" + JSON.stringify(BuildMyStuffSearch()) + "}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (response) {
        if (response.d.length > 0) {
            while ($('#MyStuffBody tr').length > 1) {
                $('#MyStuffBody tr:last').remove();
            }

            $.each(response.d, function (index, item) {
                var templateRow = $('#templateMyStuff');

What I want to know is

function (index, item)

What is index and item here.

Thanks for explain it.

Answer 1

In other words:

$.each(array, function (index, item) { 
    //body
});

is shorthand equivalent of:

for(var index = 0; index !== array.length; index++){
    var item = array[index];
    //body
}

_{Of course,it’s far more simplyfied equivalent of real $.each implementation}
