JS实现合并json对象的方法

本文实例讲述了JS实现合并json对象的方法。分享给大家供大家参考，具体如下：

一、问题：

求json对象合并的方法

var a ={"a":"1","b":"2"}
var b ={"c":"3","d":"4","e":"5"}

想得到结果：

var c ={"a":"1","b":"2","c":"3","d":"4","e":"5"}

二、实现代码：

<script>
function extend(des, src, override){
  if(src instanceof Array){
    for(var i = 0, len = src.length; i < len; i++)
       extend(des, src[i], override);
  }
  for( var i in src){
    if(override || !(i in des)){
      des[i] = src[i];
    }
  }
  return des;
}
var a ={"a":"1","b":"2"}
var b ={"c":"3","d":"4","e":"5"}
var c = extend({}, [a,b]);
console.log(c);
</script>

运行结果：
