用 JS 解析 HTML 字符串 [英] Parse an HTML string with JS
问题描述
我想解析一个包含 HTML 文本的字符串.我想用 JavaScript 来做.
我尝试了 Pure JavaScript HTML Parser library 但似乎它解析我当前页面的 HTML，而不是从字符串.因为当我尝试下面的代码时，它会更改我的页面标题:
var parser = new HTMLtoDOM("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>"，文档);我的目标是从我读取的 HTML 外部页面中提取链接，就像字符串一样.
你知道一个 API 吗?
创建一个虚拟 DOM 元素并将字符串添加到其中.然后，您可以像操作任何 DOM 元素一样操作它.
var el = document.createElement('html');el.innerHTML = "<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>";el.getElementsByTagName('a');//锚元素的实时 NodeList添加一个 jQuery 答案来取悦粉丝！
var el = $( '' );el.html("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>");$('a', el)//所有的锚元素
I want to parse a string which contains HTML text. I want to do it in JavaScript.
I tried the Pure JavaScript HTML Parser library but it seems that it parses the HTML of my current page, not from a string. Because when I try the code below, it changes the title of my page:
var parser = new HTMLtoDOM("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>", document);
My goal is to extract links from an HTML external page that I read just like a string.
Do you know an API to do it?
Create a dummy DOM element and add the string to it. Then, you can manipulate it like any DOM element.
var el = document.createElement( 'html' );
el.innerHTML = "<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>";
el.getElementsByTagName( 'a' ); // Live NodeList of your anchor elements
Edit: adding a jQuery answer to please the fans!
var el = $( '<div></div>' );
el.html("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>");
$('a', el) // All the anchor elements
