JSLint批准的将数字转换为字符串的方法是什么？ [英] What is the JSLint approved way to convert a number to a string?

问题描述

我总是通过向他们添加空字符串将数字转换为字符串：

I've always converted numbers to strings by adding an empty string to them:

var string = 1 +'';

但是，JSLint使用预期的'String'来抱怨此方法，而是看到''''。，它确实看起来有点难看。

However, JSLint complains of this method with Expected 'String' and instead saw ''''., and it does look a little ugly.

还有更好的方法吗？

推荐答案

我认为JSLint批准的方式是在号码上拨打 .toString（）：

I believe that the JSLint approved way is to call .toString() on the number:

var stringified = 1..toString();
// Note the use of the double .. to ensure the the interpreter knows 
// that we are calling the toString method on a number -- 
// not courting a syntax error.
// You could also theoretically call 1["toString"];
