jq使用localStorage实现保存密码

//读取
//获取用户名密码
user_name = $("input[name='user_name']").val();
user_pass = $("input[name='user_pass']").val();

//判断浏览器是否支持localStorage
if(window.localStorage){
       //判断是否保存密码
       if ($("input[name='storage']").prop('checked')) {
       //保存
              localStorage.user_name = user_name;
              localStorage.user_pass = user_pass;
              localStorage.storage = 1;
       }else{
              //清空
              localStorage.clear();
       }
}

//读取保存数据
//判断浏览器是否支持localStorage
if(window.localStorage){
       //之前存的，判断是否保存密码
       if (localStorage.storage) {
             $("input[name='storage']").prop('checked',true);
       }else{
             $("input[name='storage']").prop('checked',false);
       }
       //读取并赋值
      $("input[name='user_name']").val(localStorage.user_name);
      $("input[name='user_pass']").val(localStorage.user_pass);
}
