将当前网页复制到新窗口 [英] Copy Current Webpage Into a New Window
问题描述
我需要能够将当前网页复制到新的弹出窗口以进行打印预览。页面上有一个带子项的网格，所以如果他们展开其中一行来查看子行，我需要在新窗口中显示它。
I need to be able to copy the current webpage into a new popup window for a print preview. There is a grid on the page with children, so if they expand one of the rows to see the child rows, I need to show this in the new window.
是这可能吗？
我目前有弹出窗口打开同一页面，但所有行都没有展开。
I currently have the popup window open up the same page, but all none of the rows are expanded.
推荐答案
也许这就行了（在IE和Firefox中，不在Opera中。不知道WebKit）：
Perhaps this does the trick (in IE and Firefox, not in Opera. Don't know about WebKit):
var yourDOCTYPE = "<!DOCTYPE html..."; // your doctype declaration
var printPreview = window.open('about:blank', 'print_preview');
var printDocument = printPreview.document;
printDocument.open();
printDocument.write(yourDOCTYPE+
"<html>"+
document.documentElement.innerHTML+
"</html>");
printDocument.close();
（注意 window.open（）和 document.open（）！）
然而，你将丢失所有自定义DOM内容，例如事件处理程序等。尽管如此，如果您只是想复制'粘贴HTML。
However, you will lose all custom DOM thingies, like event handlers and so on. Nonetheless, it might work if you just want to copy 'n paste your HTML.
