如何在内部<span>或</span>内部转义 HTML<div> <span>标签</span>

Question

<h4>    
  <span class="title">
      <textarea rows="4" cols="50"> How are you. </textarea>
  </span>
</h4>

How to consider <textarea rows="4" cols="50"> How are you. </textarea> <textarea rows="4" cols="50"> How are you. </textarea> as a string and not HTML. I don't want HTML to render, I just want whatever comes into div or span it should render.

EXPECTED RESULT : <textarea rows="4" cols="50"> How are you. </textarea> <textarea rows="4" cols="50"> How are you. </textarea>

Answer 1

With JQuery just use text() instead of html() to insert the code:

 $('span').text('<textarea rows="4" cols="50"> How are you. </textarea>');

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <h4> <span class="title"></span> </h4>

Answer 2

Using pure JavaScript, without any library, you can use a function to insert the code as a text node in some container.

 function insertAsText( containerId, text ) { var container = document.getElementById( containerId ); var textNode = document.createTextNode( text ); container.appendChild( textNode ); } insertAsText( "myDiv", "<p><textarea>test</textarea></p>");

 <div id="myDiv"></div>

Answer 3

I just added an ID to the target textarea for convenience:

 console.log(document.getElementById('txtArea'));

 <h4> <span class="tip" 4 "=" cols="50" original-title="title"> Hi hello <span class="title"><textarea rows="4" cols="50" id="txtArea"> How are you. </textarea></span> </span> </h4>

Answer 4

You need to escape the html you want to show

&lt; is <
&quot; is ""
&gt; is >

There is an online tool that can do this for you here , but you can find many scripts that can do it for in runtime.

 <h4> <span class="title"> &lt;textarea rows=&quot;4&quot; cols=&quot;50&quot;&gt; How are you. &lt;/textarea&gt; </span> </h4>

Answer 5

Pure JavaScript:

document.getElementsByClassName("title")[0].innerHTML = "<div>HI!</div>";
//Result will be "HI!"
document.getElementsByClassName("title")[0].innerText = "<div>HI!</div>";
//Result will be "<div>HI!</div>"

JQuery:

$(".title").html("<div>HI!</div>");
//Result will be "HI!"
$(".title").text("<div>HI!</div>");
//Result will be "<div>HI!</div>"

As a final comment, those ways are get/set.
