jquery:$.ajax()

注意返回时，json的格式最好是"key":"value"的形式，否则有时会取不到返回值。



.html
$.ajax({
                type: "post",
                url: "AjaxMaking.aspx",
                success: function (data, textStatus) {
                    var j = eval(data);
                    $.each(j, function (i, item) {
                        alert(item.count);

                    });

                },
                complete: function (XMLHttpRequest, textStatus) {

                    //HideLoading();
                },
                error: function () {

                    //请求出错处理
                }
            });
