How do I get the entire page's HTML with jQuery?
提问by Justin Lee
I used $(document).html(), but that threw an error... is there a way to get everything?
我用过$(document).html()，但那抛出了一个错误......有没有办法得到一切？

Don't forget the <html>tag can have attributes too. If you want the whole document this should work.
不要忘记<html>标签也可以有属性。如果你想要整个文档，这应该可以工作。
$('html')[0].outerHTML
It's also trivial without jQuery.
没有 jQuery，这也很简单。
document.documentElement.outerHTML
If you also want to include the doctype, it's a little more involved.
如果您还想包含 doctype，那就有点复杂了。
var getDocTypeAsString = function () {
var node = document.doctype;
return node ? "<!DOCTYPE "
+ node.name
+ (node.publicId ? ' PUBLIC "' + node.publicId + '"' : '')
+ (!node.publicId && node.systemId ? ' SYSTEM' : '')
+ (node.systemId ? ' "' + node.systemId + '"' : '')
+ '>\n' : '';
};
getDocTypeAsString() + document.documentElement.outerHTML

You could try:
你可以试试：
$("html").html();
If you want to also capture the html tags you could concatenate them to the html like this:
如果您还想捕获 html 标签，您可以像这样将它们连接到 html：
function getPageHTML() {
return "<html>" + $("html").html() + "</html>";
}

$("html").html()would get everything but the outer most html tags.
$("html").html()将获得除最外层 html 标签之外的所有内容。

No need to lean on jQuery. The best and simplest approach is to use
无需依赖 jQuery。最好和最简单的方法是使用
new XMLSerializer().serializeToString(document)
which will always give you the contents of the entire page includingDOCTYPE tag, and it is supported in all modern browsers: https://caniuse.com/#feat=xml-serializer
这将始终为您提供包括DOCTYPE 标签在内的整个页面的内容，并且所有现代浏览器都支持它：https: //caniuse.com/#feat=xml-serializer
