(如何将JavaScript对象转换为字符串？)

Example:

var o = {a:1, b:2}
console.log(o)
console.log('Item: ' + o)

Output:

(输出：)

Object { a=1, b=2} // very nice readable output :)

(对象{a = 1，b = 2} //非常好的可读输出:))

Item: [object Object] // no idea what's inside :(

I would recommend using JSON.stringify , which converts the set of the variables in the object to a JSON string.

(我建议使用JSON.stringify ，它将对象中的变量集转换为JSON字符串。)

Most modern browsers support this method natively, but for those that don't, you can include a JS version :

(大多数现代浏览器本机支持此方法，但对于那些不支持此方法的浏览器，您可以包含JS版本 ：)

var obj = {
  name: 'myObj'
};

JSON.stringify(obj);
