我在这里使用高图创建了饼图，然后我希望在点击饼图区域时，控制台会根据我使用“if else”设置的条件写一些数据。
所以我有2个json数据在这里：
var json = {
"data": [

};

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userid来点击饼图区域时检索用户名并写入控制台。但它不起作用。 ：（
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");
}
}
}
}
}
},
答案 0 :(得分：0)
问题出在您的for条件中：
for (i = 0; i < jsonFB.user1[i]; i++) {
for (j = 0; j < json.data[j].audience[j]; j++) {
我认为您打算迭代所有user1和（data s和）audience，对吧？
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会起作用：
if (jsonFB.user1[i].id == json.data[k].audience[j].userid) {
但是，我必须指出，这只会确保在json和jsonFB数据之间的每次匹配时，用户名将打印到控制台一次。与图表中点击的内容没有任何关系。检查Highcharts API。我担心你必须自己制定具体细节，但我建议从event.point开始（你需要的信息似乎就在那里）：
click: function(event) {
console.log(event.point);
This demo也可能会有所帮助。
更新：如果您有多个用户（例如user1，user2等），您可以按以下方式对其进行迭代：
$.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
}
});
