Question

我是Jquery的新手，我的这个json文件看起来像这样。

 var json2 = {
        "data": [
                     {
                         "cid": "Movie",

                             },



                 ],

                         "type": "/soccer/football_team"
                     }
                 ]

    };

如何提取信息。我只想要主题名称（例如黑衣人）和人名（例如“Sandi Tan”）并附加到如下表格中：

**Men in Black, Iron man  Harry Potter**
Sandi Tan     Edmund Tan   Gibson Tay
Celia Tio                  James tan

Answer 1

json2.data[0].topic //to get Men in black
json2.data[0].audience[0].Name // to get Sandi Tan

要获取所有名称和主题，您可以使用循环

进行此操作

for(key in json2.data){
console.log(json2.data[key].topic);
console.log(json2.data[key].audience[0].Name)
}

附加到表

$('<td> Audience : '+json2.data[0].audience[0].Name+'</td><td>Topic : '+json2.data[0].topic+'</td>').appendTo(tableid);

动态添加到表格

var td ="";
for(key in json2.data){
td += "<tr><td>"+json2.data[key].topic+"</td><td>"+json2.data[key].audience[0].Name+"</td></tr>";
}
$(td).appendTo('body');

将json数据附加到表中
