2019-10-16 js 获取数组对象的某个值并组成对象

js数组中有map方法，就是专门做这个的。如下：

var list = [{"name":"zhangsan",{"name":"lisi"}}];
var get_name = function(x) {
    return x.name;
}
var new_list = list.map(add_one);

将 get_name 函数放到里面.

var list = [{"name":"zhangsan",{"name":"lisi"}}];
var new_list = list.map(function(x){
    return x.name;
});

使用lambda表达式:

var list = [{"name":"zhangsan",{"name":"lisi"}}];
var new_list = list.map(x => x.name);
