如何在HTML页面上显示原始HTML代码

如何在网页上显示HTML片段，而不需要将每个<替换为<>和>?

换句话说，是否有一个标记表示在点击结束标记之前不呈现HTML ?

我很久以前用过这个，它对我很有用，我希望它也能帮助到你。

var preTag = document.querySelectorAll（'pre'）; console.log（preTag.innerHTML）; for （var i = 0; i < preTag.length; i++） { var pattern = preTag[i].innerHTML; pattern = pattern.replace（/</g， “<”）.replace（/>/g， “>”）; 控制台.log（模式）; preTag[i].innerHTML = pattern; } <pre> <p>例</p> <span>更多文字</span> </pre>

这是一个简单的技巧，我已经在Safari和Firefox中尝试过了

<code>
    <span><</span>meta property="og:title" content="A very fine cuisine" /><br>
    <span><</span>meta property="og:image" content="http://www.example.com/image.png" />
</code>

它将显示如下:

JavaScript字符串文字可以用于跨多行编写HTML。显然，这个解决方案需要JavaScript，特别是ECMA6。

.createTextNode with CSS white-space: pre-wrap;很管用。

. innertext单独也可以。运行下面的代码片段。

let codeBlock = ` <!DOCTYPE HTML> <html lang="en"> <head> <title>My Page</title> </head> <body> <h1>Welcome to my page</h1> <p>I like cars and lorries and have a big Jeep!</p> <h2>Where I live</h2> <p>I live in a small hut on a mountain!</p> </body> </html> ` const codeElement = document.querySelector("#a"); let textNode = document.createTextNode(codeBlock); codeElement.appendChild(textNode); const divElement = document.querySelector("#b"); divElement.innerText = codeBlock; #a { white-space: pre-wrap; } <div id=a> </div> <div id=b> </div>

下面是几个答案的组合:

函数c(s) { 返回s.split(“& lt;”). join(“<”).split(“在”). join(“>”).split (", ") . join(“&”) ｝ displayMe。innerHTML = ok.innerHTML; console.log ( c (ok.innerHTML) ) <textarea style="display:none" id="ok"> <脚本> console.log(“hello”,5和9); > < /脚本 textarea > < / < div id = " displayMe " > < / div >

我认为:

你想要编写100%有效的HTML5 你想把代码片段(几乎)文字放在HTML中特别是<应该不需要转义

你所有的选项都在这棵树里:

with HTML syntax there are five kinds of elements those called "normal elements" (like <p>) can't have a literal < it would be considered the start of the next tag or comment void elements they have no content you could put your HTML in a data attribute (but this is true for all elements) that would need JavaScript to move the data elsewhere in double-quoted attributes, " and &thing; need escaping: " and &thing; respectively raw text elements <script> and <style> only they are never rendered visible but embedding your text in Javascript might be feasable Javascript allows for multi-line strings with backticks it could then be inserted dynamically a literal </script is not allowed anywhere in <script> escapable raw text elements <textarea> and <title> only <textarea> is a good candidate to wrap code in it is totally legal to write </html> in there not legal is the substring </textarea for obvious reasons escape this special case with </textarea or similar &thing; needs escaping: &thing; foreign elements elements from MathML and SVG namespaces at least SVG allows embedding of HTML again... and CDATA is allowed there, so it seems to have potential with XML syntax covered by Konrad's answer

注意:>从来不需要转义。甚至在正常元素中也没有。
