window.open和$(document).ready [英] window.open and $(document).ready

问题描述

我试图制作一个可打开弹出窗口的小书签.在此窗口内的是CSS类列表，这些类一旦被选中，就会在window.opener页面上突出显示该对象.所以我遇到了两个问题.

I am trying to make a bookmarklet that opens a popup window. Inside this window is a list of CSS classes that once selected, highlights that object on window.opener page. So I'm running into two problems.

1. Firebug在弹出窗口中不起作用，所以我看不到发生了什么事.
2. 窗口永远不会完成加载(至少我可以在Firefox中知道)，因此窗口内的$(document).ready(function(){...})永远不会执行.

1. Firebug doesn't work in the popup window, so I can't see what's going on.
2. The window never finishes loading (at least I can tell in Firefox) so the $(document).ready(function(){...}) inside the window never gets executed.

由于遇到跨域问题，所以无法从远程位置打开弹出窗口.这是一些示例代码:

I can't open the popup from a remote location because I run into cross domain issues. Here is some sample code:

<script type="text/javascript">
function makepopup(){
 var popup = '<!DOC'+'TYPE HT'+'ML PUBLIC "-//W3C//DTD HT'+'ML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">' +
 '<ht'+'ml><he'+'ad><title>Test</title>' +
 '<scr'+'ipt type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></scr'+'ipt>' +
 '</he'+'ad><bo'+'dy>' +
 '<div id="wrap">' +
  'testing popup' +
 '</div>' +
 '<input type="button" value="Click Me" />' +
 '<scr'+'ipt type="text/javascript">' + 
 '$(document).ready(function(){' +
 '$(":input").click(function(){ alert($(window.opener.doc'+'ument).find("#test").html()) });' +
 '})' +
 '</scr'+'ipt>' +
 '</bo'+'dy></ht'+'ml>';
 var testpopup = window.open( '','test','toolbar=1,location=0,status=0,width=500,height=450,scrollbars=1' );
 testpopup.document.write(popup);
 return false;
}
</script>

<a href="#" onclick="javascript:makepopup()">Open popup</a>

<div id="test" style="display:none">This is hidden text</div>

如果我在弹出窗口$(":input").click(function(){ alert($(window.opener.document).find("#test").html()) });中将以下内容添加到控制台中，则可以正常工作，因此我确定它永远不会被调用.

If I add the following to the console in the popup $(":input").click(function(){ alert($(window.opener.document).find("#test").html()) });, it works fine, so I'm sure it the document.ready never being called

或者，有更好的方法吗?

Or, is there a better way to do this?

推荐答案

如果在return false之前添加以下行，则$(document).ready是否会触发?

Does the $(document).ready fire if you add the following line before the return false?

testpopup.document.close();

尽管这是一个疯狂的猜测，但我尚未对此进行测试.

This is a wild guess though, and I haven't tested this.
