检查HTML 5 localStorage [英] Check for HTML 5 localStorage

问题描述

如何检查用户浏览器的HTML 5 localStorage兼容性？

How to check for HTML 5 localStorage compability of the users browser?

我一直在使用两张支票：

I have been using two checks:

    if (window.localStorage) {
       // localStorage works!
    }

和

    if (typeof(localStorage) != 'undefined') {
         // localStorage works!
    }

另外，我在网上看过一个使用try / catch块的函数检查localStorage是否可以添加密钥/数据对，或者抛出错误。

Also, I have seen a function online which uses an try/catch block to check whether localStorage can add a key/data pair, or throws an error.

您会推荐这三种方法中的哪一种，第一种和第二种之间是否存在差异？

Which of those three methods would you recommend, and are there any differences between the first and the second?
