我有一个 json 文件，有一个对象数组。在第一个对象中是带有 +/- 200 个对象的第二个数组。是否有可能在第一个表的最后一行的新表中显示第二个数组？

如此处所示，列中应该有一个嵌套表：“朋友”

html是：

<body onLoad="buildHtmlTable()">
<table id="excelDataTable" border="1">
</table>
</body>

其余的代码是：

var myList=[{
"id": "220439",
"name": "Bret Taylor",
"friends": {
  "data": [

        "id": "100003461417780",

你可以通过这种方式访问​​内部数据：myList[0].friends.data[i].id 和 myList[0].friends.data[i].name，只需迭代直到 myList[0].friends.data.length达到并构建您想要的任何结构 - 例如为每个朋友创建表行，有两个 td - 一个用于 id，一个用于 name – magyar1984

http://jsfiddle.net/6v8Ew/1/

for (var x = 0 ; x < myList[0].friends.data.length ; x++){

                $line.append( $( "<td></td>" ).html( myList[0].friends.data[x].id ) );
}
