JS操作文件，添加数据

Question

我这里有一个文件，内容如下：

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

我想在items后面添加数据，数据格式和上面一样，请问怎么弄，谢谢啦！

Answer 1

这是json格式，一层层剥离出来就行了

 var a={Item:[{month:'03',items:[{name:'买插座',money:'50',date:'2015-3-1'},{name:'买**',money:'200.5',date:'2015-3-2'}]},{month:'04',items:[{name:'买插座1',money:'50',date:'2015-4-1'},{name:'买**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'
        })
 }
