IE8和localStorage支持 [英] IE8 and localStorage support

问题描述

我不确定IE8是否完全支持localStorage。
但是我使用以下方法来检测

  function supports_html5_storage（）
 {
 try {
在窗口&&中返回'localStorage' window ['localStorage']！== null; 
} 
 catch（e）{
 return false; 
} 
} 
  

现在IE在窗口中为'localStorage'返回true / p>

但是窗口返回undefined ['localStorage']

所以我应该更新这个方法还是IE8确实有本地存储支持？

解决方案

您可以尝试设置和读取localStorage。

如果已禁用Cookie或您正在使用file：protocol，某些浏览器会返回安全错误
。

  function hasStorage（）{
 try {
 localStorage.setItem（'test'，'7'）; 
 if（localStorage.getItem（'test'）==='7'）{
 localStorage.removeItem（'test'）; 
返回true; 
} 
} 
 catch（呃）{} 
返回false; 
} 
  

警告（hasStorage（））

I am not sure if IE8 fully supports localStorage. But I use the following method to detect

function supports_html5_storage() 
{
    try { 
    return 'localStorage' in window && window['localStorage'] !== null; 
    } 
    catch (e) {
    return false; 
    } 
}

Now IE returns true for 'localStorage' in window

But returns undefined for window['localStorage']

So should I update this method OR does IE8 indeed have local storage support ?

解决方案

You can try to set and read localStorage.

Some browsers return a security error if cookies are disabled or you are working with file: protocol.

function hasStorage(){
    try{
        localStorage.setItem('test', '7');
        if(localStorage.getItem('test')=== '7'){
            localStorage.removeItem('test');
            return true;
        }
    }
    catch(er){}
    return false;
}

alert(hasStorage())
