window.close（）的 [英] window.close()

问题描述

大家好，


请指导我当前关于window.close（）的论文。


我的信息是一个窗口可以关闭，只要它已经由

相同文档中的相同脚本或函数打开了
。


这是我有，但没有成功：


功能窗口（网址）{

var pdf = window.open（url，null， resizable，scrollbars"）;

setTimeout（" pdf.close（）"，2000）;

}


请澄清，或者帮助......非常感谢！

Hi all,

Please direct me to a current treatise of window.close().

My info is that a window can be closed provided it has
been opened by the same script or functions within the
same document.

And this is as far as I''ve got, but no success:

function window(url) {
var pdf = window.open (url,null,"resizable,scrollbars");
setTimeout("pdf.close()", 2000);
}

Please clarify, or help... and many thanks!

通常，尝试关闭

窗口的代码是否在同一个脚本或函数中并不重要。如果窗口没有用脚本打开
，则不应该用脚本关闭它。


但打开新窗口的最大问题是弹出窗口阻止

可能会阻止它们打开，所以关闭它们的能力是否是一个相对无关紧要的副问题。 />
互联网。

Generally it would not matter that the code that attempted to close a
window was in the same script or function or not. If the window was not
opened with a script it should not be possible to close it with a script.

But the biggest issue with opening new windows is that pop-up blocking
may prevent them opening at all, so the ability to close them or not is a
relatively insignificant side issue in terms of designing for the
Internet.

这就是我所拥有的，但没有成功：

And this is as far as I''ve got, but no success:

制作没有成功你解释你的代码

实际上做什么的程度往往不会给你任何有用的帮助。

Making "no success" the extent of your explanation of what your code
actually does will tend not to get you any useful help.

函数窗口（url） {

var pdf = window.open（url，null，" resizable，scrollbars"）;

setTimeout（" pdf.close（）"，2000） ;

}

function window(url) {
var pdf = window.open (url,null,"resizable,scrollbars");
setTimeout("pdf.close()", 2000);
}

作为 - setTimeout的第一个参数提供的字符串值是

在全局执行上下文，你的 - pdf - 被声明为
作为局部变量，因此在全局执行中可能未知

上下文。


Richard。

The string values provided as the first argument to - setTimeout - are
evaluated in the global execution context, and your - pdf - is declared
as a local variable, and so probably unknown in the global execution
context.

不要使用单词窗口，

因为这是为你的后续使用而保留的。


2

pdf未全局定义，

因此超时无法使用执行


3

两秒钟是一个很短的时间

来设置一个远远不能再移除的窗口


试试：


< script type =''text / javascript''>

var w;


函数doit（url）{

w = window.open（url）;

setTimeout（''w.close（）' '，15000）;

};


< / script>


< button onclick =' '度特（QUOT; HTTP：//cnn.com/"）''>

cnn< / button>

Do not use the word window,
as this is reserved for your subsequent use.

2
pdf is not globally defined,
so not available to the timeout execution

3
Two seconds is a short time
to set up a window far inough to remove it again

try:

<script type=''text/javascript''>
var w;

function doit(url) {
w = window.open(url);
setTimeout( ''w.close()'', 15000);
};

</script>

<button onclick=''doit("http://cnn.com/")''>
cnn</button>
