JavaScript函数从字符串创建结构化对象？ [英] JavaScript function to create a structured Object from a String?

问题描述

有人可以帮我创建一个JavaScript函数，将下面的字符串变成一个Object吗？

  var structure =' user.location.city; 
  

运行JavaScript函数时，会返回一个像这样的对象：

 用户：{
位置：{
 city：{} 
} 
} 
  

我想出了下面的代码，但是这个对象很乱：

  var path = structure.split（'。'）; 
 var tmp_obj = {}; 
 for（var x = 1; x  tmp_obj [path [x]] = {}; 
}; 
  

我不知道如何将城市对象添加到位置对象。 / p>

解决方案

  var path = structure.split（'。'）; 
 var tmp_obj = {}; 
 var obj = tmp_obj; 
 for（var x = 1; x  tmp_obj [path [x]] = {}; 
 tmp_obj = tmp_obj [path [x]]; 
}; 
  

Could someone help me to create a JavaScript function that would turn the string below into an Object?

var structure = 'user.location.city';

When ran through the JavaScript function would return an object structured like this:

user: {
  location: {
    city: {}
  }
}

I came up with the code below, but the object is messed up:

var path = structure.split('.');
var tmp_obj = {};
for ( var x = 1; x < path.length; x++ ) {
   tmp_obj[path[x]] = {};
};

I don't know how to add the "city" Object to the "location" Object.

解决方案

var path = structure.split('.');
var tmp_obj = {};
var obj = tmp_obj;
for(var x = 1; x < path.length; x++) {
    tmp_obj[path[x]] = {};
    tmp_obj = tmp_obj[path[x]];
};
