本文章分享一篇关于jq和js遍历json数据方法,有需要的同学可以参考一下下哈。
 代码如下 复制代码

function:
var __db_cpcj=vCpcj;
var __db_cp=vCp;
var vCp={“cppage”:[
{"cpdh":"A01000101","page":"1","ca":"1309-36-0","mc":"硫铁矿","ename":"Pyrite","bm":"黄铁矿"},

如何遍历jsonc对象?其实方法很简单。

比如有如下json对象:

 代码如下 复制代码

var obj ={”name”:”冯娟”,”password”:”123456″,”department”:”技术部”,”sex”:”女”,”old”:30};

遍历方法:

 代码如下 复制代码

for(var p in obj)

{

str = str+obj[p]+’,’;
return str;

}
