在unload事件上需要srcElement的帮助 [英] Need help with srcElement on unload event
问题描述
我有一个页面，如果他试图退出页面，我需要向用户显示弹出窗口。我已经写了一个onunload函数，它负责显示弹出窗口。但是，如果用户单击站点上的某些链接，则不应向用户显示弹出窗口。这些链接还会导致页面被卸载。我正在使用srcElement来识别已单击的链接。不幸的是，在我的函数中，srcElement对象变为null。我厌倦了请求帮助。如果有任何代码示例，我会非常有帮助。
I have a page on which i need to show a pop up to the user if he tries to exit the page . I have already written an onunload function which takes care of displaying the popup . But the popup should not be displayed to the user if the user clicks on certain links on the site . These links also cause the page to be unloaded. I am using the srcElement to identify which link has been clicked . Unfortunately , in my function srcElement object is coming null . I am tired of trying please help. If there are any code samples i would be really helpful.

Heya，Nileshs。欢迎来到TSDN！
更改主题标题以更好地描述问题。
让特定链接设置一个卸载功能检查的全局变量在显示弹出窗口之前。
Heya, Nileshs. Welcome to TSDN!
Changed thread title to better describe the problem.
Have the specific links set a global variable that your unload function checks for before showing the popup.
谢谢你们
下面是我编写的示例代码。我只是想让这个工作。
我稍后会将它集成到我的应用程序中。
[HTML]<！DOCTYPE HTML PUBLIC" - // W3C // DTD HTML 4.0 Transitional // EN">
< HTML> ;
< HEAD>
< TITLE>新文档< / TITLE>
< script>
函数showSource（）{
var x = window.event.srcElement;
alert（" Source Elemt" + x）;
var y = window.event.type;
alert（" Source Event） + y）;
}
< / script>
< / HEAD>
< ; BODY onUnload =" showSource（）;">
< A id =" google" HREF =" http：//www.google.com"> Google< / A>
< A id =" yahoo" HREF =" HTTP：//www.yahoo.com" > Yahoo< / A>
< / BODY>
< / HTML> [/ HTML]
Thanks guys
Below is a sample code that I have written. I am just trying to make this work .
I will integrate it into my application later.
[HTML]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<script>
function showSource() {
var x= window.event.srcElement;
alert("Source Elemt "+x);
var y = window.event.type;
alert("Source Event "+y);
}
</script>
</HEAD>
<BODY onUnload="showSource();">
<A id="google" HREF="http://www.google.com">Google</A>
<A id="yahoo" HREF="http://www.yahoo.com" >Yahoo</A>
</BODY>
</HTML>[/HTML]
