JQuery Ajax部分用于更新页面而不刷新我使用

$('document').ready(function () {
    // alert("JeuryIsOnline");
    $('#DivRobCounterRes').fadeTo(4, 0);
    $('.Span_imgMemeBase').click(
        function () {
            var Spars = [];
            Spars.push("egnition");
            for (i = 1; i < 11; i++)
            jQuerySendCfrm(Spars);
     });

});    // EndJquery Ready Code 

function jQuerySendCfrm(resluts) {
    var SentClientinfo = []
    SentClientinfo.push({ key: "SentClientinfo", value: resluts });
    var CurrpageURL = "default.aspx/";
    var WebmethodName = "StartTest";
    var StageIdentifyer = "stage1";
    var Post_TargetUrl = CurrpageURL + WebmethodName;
    jQueryAajaxNoPostBack(Post_TargetUrl, SentClientinfo, StageIdentifyer);
}

function jQueryAajaxNoPostBack(targetUrl, passedSentPars, StageIdentifyer) {
