Answer 1

只需要解析mainMenu[8].subMenu[i].name[0]那一列，
回2楼
不是我不要统一，是我们老总非要这么弄，
我开始在JS中把JSON数组和多维数组解析都是共用一个方法的，
结果他说不行，就把数组改成这样了。

Answer 2

恩
循环的时候写个
if(mainMenu[8].subMenu[0].name[0].name){
// 表示 格式是这种的 name:[{name:"便民付费1"},{name:"便民付费1"}]
}else{
//name:["我的收藏",""]
}

Answer 3

那就把格式处理成统一的：
for (var i = 0; i < mainMenu.length; i ++) {
for (var j = 0; j < mainMenu[i].subMenu.length; j ++) {
if (typeof(mainMenu[i].subMenu[j].name[0]) != 'string') {
var ar = [];
for (var k = 0; k < mainMenu[i].subMenu[j].name.length; k ++) ar.push(mainMenu[i].subMenu[j].name[k].name);
mainMenu[i].subMenu[j].name = ar;
}
}
}

Answer 4

var obj=mainMenu[8]['subMenu'];
var arr=new Array();
for(var i in obj){
       if(typeof (obj[i].name[0])=='object')
             arr.push(obj[i].name[0].name);
        else 
        arr.push(obj[i].name[0]);
}
alert(arr);
