thinkphp+js記錄讀取用戶名功能

先把用戶名寫到cookie裏

if($_POST['tousernamea']==1){cookie('tousernamea',$_POST['username'],60*60*24*365);}<span style="font-family: Arial, Helvetica, sans-serif;">	</span>

如果勾選記錄，那麼就寫入cookie，時間一年

然後在js中讀取

方法一
var acookie=document.cookie.split("; ");
function getck(sname)
{//獲取單個cookies
for(var i=0;i<acookie.length;i++){
var arr=acookie[i].split("=");
if(sname==arr[0]){
if(arr.length>1)
return unescape(arr[1]);
else
return "";}}
return "";
}

方法二
function getcookie(objname){//獲取指定名稱的cookie的值
var arrstr = document.cookie.split("; ");
for(var i = 0;i < arrstr.length;i ++){
var temp = arrstr[i].split("=");
if(temp[0] == objname) return unescape(temp[1]);
}
}
方法三
function   getcookie(cookiename){ 
var   cookiestring   =   document.cookie; 
var   start   =   cookiestring.indexof(cookiename   +   '= '); 
if   (start   ==   -1)   //   找不到 
return   null; 
start +=   cookiename.length   +   1; 
var   end   =   cookiestring.indexof( "; ",   start); 
if   (end   ==   -1)   return   unescape(cookiestring.substring(start)); 
return   unescape(cookiestring.substring(start,   end)); 
}

方法四
function readcookie(name)   
  
{   
  
  var cookievalue = "";   
  
  var search = name + "=";   
  
  if(document.cookie.length > 0)   
  
  {    
  
    offset = document.cookie.indexof(search);   
  
    if (offset != -1)   
  
    {    
  
      offset += search.length;   
  
      end = document.cookie.indexof(";", offset);   
  
      if (end == -1) end = document.cookie.length;   
  
      cookievalue = unescape(document.cookie.substring(offset, end))   
  
    }   
  
  }   
  
  return cookievalue;   
  
}
