js-JS操作文件，添加數據

JS操作文件，添加數據

我這裡有一個文件，內容如下：

 {Item:[{month:'03',items:[{name:'買插座',money:'50',date:'2015-3-1'},{name:'買**',money:'200.5',date:'2015-3-2'}]},{month:'04',items:[{name:'買插座1',money:'50',date:'2015-4-1'},{name:'買**1',money:'200.5',date:'2015-4-2'}]}]}

我想在items後面添加數據，數據格式和上面一樣，請問怎麼弄，謝謝啦！

最佳回答：

這是json格式，一層層剝離出來就行了

 var a={Item:[{month:'03',items:[{name:'買插座',money:'50',date:'2015-3-1'},{name:'買**',money:'200.5',date:'2015-3-2'}]},{month:'04',items:[{name:'買插座1',money:'50',date:'2015-4-1'},{name:'買**1',money:'200.5',date:'2015-4-2'}]}]};
 var item = a['Item'];
 for(var i=0;i<item.length;i++){
    item[i].items.push({
            name:'新插座'+i,
                money:'1000',
                date:'2015-5-1'
        })
 }
