关闭浏览器后出现的弹窗代码,支持跳转

来源:本站原创 浏览:264次 时间:2015-12-02

  相信很多朋友都遇到过,打开的网页明明都点击关闭浏览器的按钮了,还会提示一个弹窗出来问你需不需要关闭,网上很多下面的这种代码

  window.onbeforeunload = onbeforeunload_handler;

  function onbeforeunload_handler(){

  var warning="你确定要离开vincent博客吗?";

  return warning;

  }

  但是这种代码点击留在此页网页只能显示在当前页面!下面的代码就不同与这种了,点击留在此页后可以设置跳转到指定的页面!

  /*vincent http://www.tbhyb.com*/

  var exitsplashmessage = '你确定要离开vincent博客吗?';

  var exitsplashpage = 'http://www.tbhyb.com';

  function addLoadEvent(func) {

  var oldonload = window.onload;

  if (typeof window.onload != 'function') {

  window.onload = func;

  } else {

  window.onload = function() {

  if (oldonload) {

  oldonload();

  }

  func();

  }

  }

  }

  /*vincent http://www.tbhyb.com*/

  function addClickEvent(a, i, func) {

  if (typeof a[i].onclick != 'function') {

  a[i].onclick = func;

  }

  }
