You can always define your own toString method, but JSON.stringify will give you a close enough result:

您始终可以定义自己的toString方法,但JSON.stringify将为您提供足够接近的结果:

var x=[{a:1},{b:2},{c:3}];

alert(JSON.stringify(x));

#2

You should be able to use JSON.stringify(x)

你应该能够使用JSON.stringify(x)

But if you just do this in order to debug, then you'd better use the console with console.log(X).

但是如果你只是为了调试而这样做,那么你最好使用console.log(X)控制台。
