Question

第一次使用Ajax调用在加载事件上给出了完美的结果，但是当我使用Element的单击事件（Recall）调用它时，它将给出响应：文本空白，状态代码：200 OK。

var url = window.location.href;
var customerId = 1;
var OrderBy = 0;

if (url.indexOf('?' + paramCategoryId + '=') != -1) {
    var categoryId = parseInt(decodeURIComponent(window.location.search.match(/(\?|&)categoryId\=([^&]*)/)[2]));
    if (categoryId > 0) {

        GetProductsByCategory(customerId, categoryId, OrderBy); // onLoad Ajax Call

        $("ul.sorting li:not(:eq(0)) > a").on('click', function() { // On Element Click Event
            OrderBy = $(this).parent('li').attr('Id');
            console.log(OrderBy);
            GetProductsByCategory(customerId, categoryId, OrderBy);

        });

    }
}

function GetProductsByCategory(customerId, categoryId, OrderBy) {

    $.ajax({
        type: "POST",
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        url: url,
        data: '{"customerId":"' + customerId + '","categoryId":"' + categoryId + '","command":{"PageSize":"8","PageNumber":"1","OrderBy":"8"}}',
        cache: true,
        async: true,
        complete: function(data) {
            if (data == "undefined") {
                targetElement.html(content);
                return;
            }
            var resData = JSON.parse(data);
            var categoryResult = resData.CategoryResult;
            BindProductsByDisplayMode(CallType.Category, viewType, targetElement, categoryResult);
        },
        error: function(xhr, textStatus, error) {
            targetElement.html(content);
        }
    });
}

在第二次呼叫时，仅更改了发布请求参数OrderBy。默认OrderBy = 0 ;但是当我调用Second Time时，它会在

处给出响应空白和错误

var resData = JSON.parse(data);  => 'undefined '

当Ajax方法为Recall时，响应文本为空
