带有cookie的javascript欢迎消息 [英] javascript welcome message with cookie

问题描述

嗨！你可以帮我改进这段代码吗？当点击确定时，设置了cookie但是当点击取消时，没有设置cookie

Hi! Can you help me improve this code in that when "OK" is clicked, cookie is set but when "Cancel" is clicked, cookie is not set

function rC(nam) 
{
var tC = document.cookie.split('; '); 
for (var i = tC.length - 1; i >= 0; i--) 
{
  var x = tC[i].split('=');
  if (nam == x[0]) 
    return unescape(x[1]);
} 
return '~';
} 

function wC(nam,val) 
{
document.cookie = nam + '=' + escape(val);
} 

function lC(nam,pg) 
{
var val = rC(nam); 
if (val.indexOf('~'+pg+'~') != -1) 
  return false; 

val += pg + '~'; 
wC(nam,val); 
return true;
} 

function firstTime(cN) 
{
return lC('pWrD4jBo',cN);
} 

function thisPage() 
{
var page = location.href.substring(location.href.lastIndexOf('\/')+1); 
pos = page.indexOf('.');
if (pos > -1) 
{
page = page.substr(0,pos);
} 
return page;
}

// example code to call it - you may modify this as required
function start() {
   if (firstTime(thisPage())) {
      // this code only runs for first visit
      var answer = confirm ("Please click on OK to continue loading my page, or CANCEL to be directed to the Yahoo site.")
if (!answer)
window.history.back();
   }
   // other code to run every time once page is loaded goes here
}
onload = start;

// example code to call it - you may modify this as required
function start() {
   if (firstTime(thisPage())){
      // this code only runs for first visit
      var answer = confirm ("Please click on OK to continue loading my page, or CANCEL to be directed to the Yahoo site.");
     if(answer)
     {
       lC(nam,pg);// with whatever nam and pg is
     }
     else
     {
       window.history.back();
     }
   }
   // other code to run every time once page is loaded goes here
}
