如何在JavaScript中创建JSON字符串？ [英] How to create JSON string in JavaScript?

问题描述

window.onload = function(){
    var obj = '{
            "name" : "Raj",
            "age"  : 32,
            "married" : false
            }';

    var val = eval('(' + obj + ')');
    alert( "name : " + val.name + "\n" +
           "age  : " + val.age  + "\n" +
           "married : " + val.married );

}

在这样的代码中，我正在尝试创建JSON字符串只是为了玩。这是错误，但如果我把所有的名字，年龄，结婚在一行（第2行），它不会。问题是什么？

In a code something like this, I am trying to create JSON string just to play around. It's throwing error, but if I put all the name, age, married in one single line (line 2) it doesn't. Whats the problem?

推荐答案

Javascript不会处理多行的字符串。

Javascript doesn't handle Strings over multiple lines.

你需要连接这些：

var obj = '{'
       +'"name" : "Raj",'
       +'"age"  : 32,'
       +'"married" : false'
       +'}';

您还可以在ES6及以上版本中使用模板文字：（请参阅此处获取文档）

You can also use template literals in ES6 and above: (See here for the documentation)

var obj = `{
           "name" : "Raj",
           "age" : 32,
           "married" : false,
           }`;
