如何在对象内创建 JavaScript 对象？

发布于 2024-11-08 13:50:39 字数 321 浏览 0 评论 0原文

例如：

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    this.cars = function() {
        this.value = start_value;
        this.count = start_value;
    };
}

显然上述内容不起作用，但希望了解如何让汽车可用： userObject.cars.value = 100000;

干杯!

For example:

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    this.cars = function() {
        this.value = start_value;
        this.count = start_value;
    };
}

Obviously the above dosent work but would appreciate the direction to take to have cars available as:
userObject.cars.value = 100000;

Cheers!

请记住，函数（以及“对象定义”）可以嵌套（绝对不要求嵌套，但将其嵌套在此处允许对 start_value 进行闭包）：

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    function subObject () {
        this.value = start_value;
        this.count = start_value;
    }
    this.cars = new subObject();
}

但是，我可能会选择为此（只需创建一个新的“普通”对象）：

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    this.cars = {
        value: start_value,
        count: start_value
    };
}

快乐编码。

Remember that functions (and thus "object definitions") can be nested (there is absolutely no requirement that this is nested, but having it nested here allows a closure over start_value):

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    function subObject () {
        this.value = start_value;
        this.count = start_value;
    }
    this.cars = new subObject();
}

However, I would likely opt for this (just create a new "plain" Object):

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    this.cars = {
        value: start_value,
        count: start_value
    };
}

Happy coding.

如此简单的 anser 就是使用对象语法

function userObject(start_value) {  
 this.name = start_value;
 this.address = start_value;
 this.cars = {
  value: start_value,
  count: start_value
 };
}

so simple anser is to use the object syntax

function userObject(start_value) {  
 this.name = start_value;
 this.address = start_value;
 this.cars = {
  value: start_value,
  count: start_value
 };
}
