# 合并示例1 ``` var str1=[{name:"11",age:11}]; var str2=[{name:"22",age:22}]; ``` 想要結果： ``` var str3=[{name:"11",age:11},{name:"22",age:22}]; ``` >注：不能用這個方法：`$.extend()` ## 方法一：push ``` var str3 = []; for (var i = 0; i < str1.length; i++) { str3.push(str1[i]); } for (var i = 0; i < str2.length; i++) { str3.push(str2[i]); } console.log(str3); ``` ## 方法二：concat ``` var str3 = str1.concat(str2); ``` # 合并示例2 `$.extend` 保存object1和2合并后產生新對象，若2中有與1相同的key，默認2將會覆蓋1的值 `` $.extend( object1, object2 ); ```
