Question

我收到未捕获的TypeError：无法在控制台中读取未定义属性'sort'错误。有人请解释这里出了什么问题。我需要做的就是通过JSON数组排序，数据已从数据库中取出并显示出来！

带编码的样本会很有用。提前感谢任何帮助！

我的阿贾克斯：

var getData;

$("form").on("submit", function () {
    var data = {
        "action": "test"
    };

    data = $(this).serialize() + "&" + $.param(data);
    $.ajax({
        type: "POST",
        dataType: "json",
        url: "ajax2.php",
        data: data,

        success: function (data) {

            getData=data;
            $("#main_content").slideUp("normal",function(){

            //$(".the-return").html("<br />JSON: " + data+"<br/>");
            for (i = 0; i < data.length; i++) {



$(".the-return").append("<div class='inside_return'>Name:" + data[i].name + "<br/>Id:" + data[i].id + "<br/>Pricing:" + data[i].rate + "<br/>Postcode:" + data[i].postcode+ "<br/>Reputation:" + data[i].reputation+"<br/>Review Plus:" + data[i].plus+"<br/>Review Negative:" + data[i].neg+"<br/><h1>Availability</h1>Week Morning:" + data[i].weekM+"<br/>Week Afternoon:" + data[i].weekA+"<br/>Week Evening:" + data[i].weekE+"<br/>Weekend Morning:" + data[i].endM+"<br/>Weekend Afternoon:" + data[i].endA+"<br/>Week Evening:" + data[i].endE+"</div>");


            //alert(data[i].name) 
        }

            });//closes #main_content
        }


    });
    return false;


});

用户点击排序按钮触发的功能：

$("#Name").on("click",function()
{
    $(".the-return").slideUp("normal",function()
    {

        getData.sort('name');

        for (i = 0; i < getData.length; i++) {
        $(".the-return2").append("<div class='inside_return'>Name:" + getData[i].name +"</div>");

        }

    });
});

排序的功能：

getData.sort(function (a, b) {
    var retVal = 0;
    switch (sortOption) {
        case 1:
            retVal = a.name > b.reputation ? 1 : (a.name < b.reputation ? -1 : 0);
            break;
    }
    return retVal;
});
