大家好，我正在尝试从本网站的 Web 服务获取此 json 文件：“http://172.20.192.218:8080/DC_Local/rest/datacorrelation?type=/soccer/football_team&limit=20&callback=?”

但是我得到了这个“Uncaught SyntaxError：Unexpected token”但我不知道有什么问题。

这是我调用 json 文件的代码：

var pts = [];
    $.getJSON("http://172.20.192.218:8080/DC_Local/rest/datacorrelation?type=/soccer/football_team&limit=20&callback=?", function(data) {
        //JSON.parse(data);

        $.each(data, function(i,v){
            pts.push([v.topic, v.audience.length]);
        });
     });

这是我想要获取的 json 文件：

{"data":[{"id":"/en/arsenal_fc","topic":"Arsenal F.C.","audience":[],"type":"/soccer/football_team"},{"id":"/en/ajax_amsterdam","topic":"Ajax Amsterdam","audience":[],"type":"/soccer/football_team"},{"id":"/en/az_alkmaar","topic":"AZ Alkmaar","audience":[],"type":"/soccer/football_team"},{"id":"/en/as_roma","topic":"A.S.

你必须写$.each(data.data, function(i,v){而不是$.each(data, function(i,v){.

样本：

<!DOCTYPE html>
<html>
    <head>
        <title>Add many Elements</title>
        <script src="jquery.js"></script>
        <script>
            $(document).ready(function() {
            var dataString = '{"data":[{"id":"/en/arsenal_fc","topic":"Arsenal F.C.","audience":[],"type":"/soccer/football_team"},{"id":"/en/ajax_amsterdam","topic":"Ajax Amsterdam","audience":[],"type":"/soccer/football_team"},{"id":"/en/az_alkmaar","topic":"AZ Alkmaar","audience":[],"type":"/soccer/football_team"},{"id":"/en/as_roma","topic":"A.S.
