我是靠谱客的博主拉长外套，这篇文章主要介绍JS localStorage实现本地缓存的方法，现在分享给大家，希望可以做个参考。

复制代码代码如下:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
  <head> 
    <title>本地缓存</title> 
    <script type="text/javascript"> 
        var strKey = "strKey"; 
        var storage = window.localStorage; 

        function onStart(){ 
            if(storage.getItem(strKey)!=null){ 
                alert(storage.getItem(strKey)+'localStorage'); 
            }else if(Cookie.read(strKey)!=null){ 
                alert(Cookie.read(strKey)+'cookie'); 
            } 
        } 
        function bendihuancun(){ 
            var strValue = document.getElementById("username").value; 
            if (storage) { 
            storage.setItem(strKey, strValue);   
        } else { 
            Cookie.write(strKey, strValue);  
        } 
        } 
    </script> 
  </head> 
  <body onload="onStart()"> 
    <input type="text" id="username" value="123"> 
    <input type="button" value="保存缓存" onclick="bendihuancun()"> 
  </body> 
</html>
