问题描述
我有一个包含页面HTML源代码的JavaScript变量(不是当前页面的源代码),我需要从该变量中提取所有链接。 什么是最好的方式的线索?
I have a javascript variable containing the HTML source code of a page (not the source of the current page), I need to extract all links from this variable. Any clues as to what's the best way of doing this?
可以为变量中的HTML创建一个DOM,然后走吗? / p>
Is it possible to create a DOM for the HTML in the variable and then walk that?
推荐答案我不知道这是否是推荐的方法,但它有效:(仅限JavaScript)
I don't know if this is the recommended way, but it works: (JavaScript only)
var rawHTML = '<html><body><a href="foo">bar</a><a href="narf">zort</a></body></html>'; var doc = document.createElement("html"); doc.innerHTML = rawHTML; var links = doc.getElementsByTagName("a") var urls = []; for (var i=0; i<links.length; i++) { urls.push(links[i].getAttribute("href")); } alert(urls)更多推荐
