JS的map和array集合组合返回JSON字符串
使⽤map 和array 返回⾃定义对象的JSON字符串:
function getObjectJSON() {
  var array = new Array();
  for (var i = 0; i < 5; i++) {
    var map = {};
    map[1] = "张三";
    map[2] = "李四";
    map[3] = "王五";字符串是什么字符的集合
    map[4] = "赵六";
    array[i] = map;
  }
  return JSON.stringify(array);
}
结果:
[{"1":"张三","2":"李四","3":"王五","4":"赵六"},{"1":"张三","2":"李四","3":"王五","4":"赵六"},{"1":"张三","2":"李四","3":"王五","4":"赵六"},{"1":"张三","2":"李四","3":"王五","4":"赵六"},{"1":"张三","2":"李四","3":"王五","4":"赵六"}]
function getObjectJSON2() {
  var array = new Array();
  for (var i = 0; i < 5; i++) {
    var map = {};
    map["name"] = "张三";
    map["age"] = "24";
    map["height"] = "172cm";
    map["address"] = "中国";
    array[i] = map;
  }
  return JSON.stringify(array);
}
结果:
[{"name":"张三","age":"24","height":"172cm","address":"中国"},{"name":"张三","age":"24","height":"172cm","address":"中国"},{"name":"张三","age":"24","height":"172cm","address":"中国"},{"name":"张三","age":"24","height":"172cm","address":"中国"},{"name":"张三","age":"24","height":"172cm","address":"中国"}]
