JS针对浏览器窗口关闭事件的监听方法集锦

本文实例总结了JS针对浏览器窗口关闭事件的监听方法。分享给大家供大家参考，具体如下：

方式一：(适用于IE浏览器，而且刷新不提示，只在点击浏览器关闭按钮的时候提示)

<script type="text/javascript">window.onbeforeunload=onclose;function onclose(){if(event.clientX>document.body.clientWidth&&event.clientY<0||event.altKey){return "您要离开吗？";}}</script>

方式二：适用于IE和FF，不区分刷新和关闭

<script type="text/javascript">  window.onbeforeunload = onbeforeunload_handler;  window.onunload = onunload_handler;  function onbeforeunload_handler(){    var warning="确认退出?";    return warning;  }  function onunload_handler(){    var warning="谢谢光临";    alert(warning);  }</script>

方式三：适用于IE和FF，不区分刷新和关闭，最简单的

<script type="text/javascript">window.onbeforeunload=onclose;function onclose(){return "您确定退出吗？";}</script>

方式四：适用于IE和FF，不区分刷新和关闭，稍复杂的

<script language="javascript">var MSG_UNLOAD="如果你此时离开档案系统，所做操作信息将全部丢失，是否离开?";var UnloadConfirm = {};//启用监听浏览器刷新、关闭的方法UnloadConfirm.set = function(confirm_msg){  window.onbeforeunload = function(event){    event = event || window.event;    event.returnValue = confirm_msg;  }}//关闭监听浏览器刷新、关闭的方法UnloadConfirm.clear = function(){  window.onbeforeunload = function(){};}UnloadConfirm.set(MSG_UNLOAD);</script>

方式五：只适用于IE6下的关闭按钮和快捷键关闭的，刷新不提示

<script type="text/javascript">window.onbeforeunload=onclose;function onclose(){var warnning = '<fmt:message key="systemMessage.exitWarning" />';var beforeExit='<fmt:message key="systemMessage.beforeExitWarning" />'; if(event.clientY<0 && event.clientX>document.body.clientWidth-20 || event.clientY<0 && event.clientX<20 ||event.altKey || event.ctrlKey || event.clientY>document.body.clientHeight){alert(beforeExit);return warnning;}}</script>

另附判断浏览器类型的JS

<script type="text/javascript">    var Sys = {};    var ua = navigator.userAgent.toLowerCase();    if (window.ActiveXObject)      Sys.ie = ua.match(/msie ([/d.]+)/)[1]    else if (document.getBoxObjectFor)      Sys.firefox = ua.match(/firefox//([/d.]+)/)[1]    else if (window.MessageEvent && !document.getBoxObjectFor)      Sys.chrome = ua.match(/chrome//([/d.]+)/)[1]    else if (window.opera)      Sys.opera = ua.match(/opera.([/d.]+)/)[1]    else if (window.openDatabase)      Sys.safari = ua.match(/version//([/d.]+)/)[1];    //以下进行测试    if(Sys.ie) document.write('IE: '+Sys.ie);    if(Sys.firefox) document.write('Firefox: '+Sys.firefox);    if(Sys.chrome) document.write('Chrome: '+Sys.chrome);    if(Sys.opera) document.write('Opera: '+Sys.opera);    if(Sys.safari) document.write('Safari: '+Sys.safari);</script>
