我在这里使用highchart创建了饼图，然后我希望当点击饼图区域时，控制台将根据我使用“if else”设置的标准写入一些数据。

所以我有2个json数据在这里：

var json = {
    "data": [
        {
        "topic": "Manchester United F.C.",
        "id": "/en/manchester_united_fc",
        "type": "/soccer/football_team",
        "audience": [
            {
            "userid": "100003921730958",
            "source": "Manchester United",
            "category": "Professional sports team"}
        ]},
    {
        "topic": "Chelsea F.C.",
        "id": "/en/chelsea_fc",
        "type": "/soccer/football_team",
        "audience": [
            {
            "userid": "100003921730958",
            "source": "Frank Lampard",
            "category": "Athlete"},
        {
            "userid": "100003914111287",
            "source": "Chelsea Football Club",
            "category": "Professional sports team"}
        ]}
    ]
};


var jsonFB = {

    "user1": [
        {
        "id": "100003921730958",
        "name": "Tan Jercia",

            "paging": {

            }
        }}
    ]
};​

所以基本上我希望我通过匹配我尝试使用循环数组匹配方法的两个用户 ID 单击饼图区域时检索用户的名称并写入控制台。但是它不起作用。:(

plotOptions: {
    pie: {
        allowPointSelect: true,
        cursor: 'pointer',
        point: {
            events: {
                click: function() {
                    for (i = 0; i < jsonFB.user1[i]; i++) {

                        for (j = 0; j < json.data[j].audience[j]; j++) {

                            if (jsonFB.user1[i].id == json.data[j].audience[j].userid) {

                                var name = jsonFB.user1[i].name;
                                console.log(name);
                            }
                            else {

                                console.log("false");
                            }

                        }
                    }

                }
            }
        },​

问题在于您的for条件：

for (i = 0; i < jsonFB.user1[i]; i++) {
    for (j = 0; j < json.data[j].audience[j]; j++) {

我认为您的意思是遍历所有user1s 和 ( datas and) audiences，对吗？

for (i = 0; i < jsonFB.user1.length; i++) {
    for (k = 0; k < json.data.length; k++) {
        for (j = 0; j < json.data[k].audience.length; j++) {

现在你的（改编的）if将工作：

if (jsonFB.user1[i].id == json.data[k].audience[j].userid) {

但是，我必须指出，这只会确保每次json和jsonFB数据匹配时将用户名打印到控制台一次。与图表中单击的内容没有任何关系。检查Highcharts API。恐怕你必须自己制定细节，但我建议从event.point（你需要的信息似乎在那里）开始：

click: function(event) {
    console.log(event.point);

这个演示也可能会有所帮助。

更新：如果您有多个用户（例如user1等user2），您可以像这样迭代它们：

$.each(jsonFB, function(prop, value) {
    if ( prop.indexOf("user") == 0 ) { // Check if the name starts with "user"
        for (i = 0; i < value.length; i++) {...} // Replaces jsonFB.user1.length
    }
});
