如何在重新加载页面时判断？ [英] how can I tell when a page is done reloading?
问题描述
我想在浏览器窗口中重新加载网址，所以我这样做：
open（window.location.href =" www.yahoo.com"）;
ok，所以现在我想在页面完成后做点什么装完
完全。我该怎么做？
我试过的是：
a = open（window.location.href =" www.yahoo.com"）;
a.onload = b（）;
函数b（）{
alert（" Done !!"）;
}
但这都不起作用。我只关心IE。
关于如何让它工作的任何建议？
我的目标，如果从上面不清楚，是加载一些任意页面一个
的窗口，然后执行<其他>，功能b（），只有当那个页面
完全加载时才会加载。
在IE中，使用正文中的onreadystatechange事件处理程序：
< body onreadystatechange =" if（this.readyState ==''loaded''）{....}">然而，
onload =的工作方式相同。

不，你不明白。我无法控制
子窗口的内容。如果我这样做，我会使用onload或者你已经建议的任何
。

两个错误：window.open（）方法有三个参数，都是可选的，
所有字符串，但你有一个脚本语句。第一个参数是
要打开的url，相对于当前页面，还是绝对的，其中
情况下协议，通常是http :,是必需的;第二个和第三个指定
名称和功能，如条形和大小。
您在此处作为参数传递的内容，是Javascript的返回值
语句window.location.href =等。这恰好是
包含url的字符串，但协议缺失所以它被解释为
相对。
你在看什么for是这样的：
window.open（" http：//www.yahoo.com"）;
a.onload = b（）;
一：在为事件处理程序分配函数时，你不一定想要执行该函数
。放下方括号（），你就没事了。
但是：这将永远不会跨域工作。浏览器内置安全性
措施可防止JavaScript访问不是来自同一个
域的网页。只有当您打开一个包含您自己网站页面的窗口时，您才能支持
附加onload事件处理程序和其他内容。有关这方面的更多信息，请尝试

I want to reload a url in a browser window so I do something like this:
open(window.location.href= "www.yahoo.com");
ok, so now I want to do something when that page is done loading
completely. how do I do this?
What I have tried is this:
a=open(window.location.href= "www.yahoo.com");
a.onload=b();
function b(){
alert("Done!!");
}
but none of this works. I am only concerned with IE.
Any advice on how I can get this to work?
My goal, if not clear from above, is to load some arbitrary page in a
window and then do <something else>, function b(), only when that page
is completely done loading.
In IE, use the onreadystatechange event handler in the Body:
<body onreadystatechange="if(this.readyState==''loaded''){ ....}"> however,
onload= works the same way.

No, you didn''t understand. I have no control over the content of the
child window. If I did I would have used onload or whatever you
suggested already.
How do I tell when a child window is done loading? WHEN I HAVE NO
CONTROL OVER THE CONTENT OF THE CHILD WINDOW.
"jaialaitech nology" wroteok, so now I want to do something when that page is done loading

a=open(window.location.href= "www.yahoo.com");
Two mistakes: the window.open() method takes three parameters, all optional,
all strings, but you have a script statement there. The first parameter is
the url to open, either relative to the current page, or absolute, in which
case the protocol, usually http:,is required; the second and third specify
the name and features such as bars and sizes.
What you pass as the parameter here, is the returnvalue of the Javascript
statement window.location.href=etc. This happens to be the string that
contains the url, but the protocol is missing so it is interpreted
relatively.
What you are looking for is something like this:
window.open( "http://www.yahoo.com" );
a.onload=b();
One: When assigning a function to an event handler, you don''t necessarily
want to execute that function. Drop the brackets () and you ''re fine.
However: this will never work cross-domain. Browser built-in security
measures prevent JavaScript from accessing pages that are not from the same
domain. Only when you open a window with a page from your own site, can you
attach onload event handlers and other stuff. For more on this, try
