If I grab some html from one element, then attempt to assign it as the text content of another element, newlines are not preserved (at least not in the latest Firefox and Chromium).

So, for example, the follow code (with sensible html) produces output where the newlines are replaced by spaces. Well, except the alert, which works as expected.

$("#info").data("html", $("#info").html());
$("#jquery").text($("#info").data("html"));
document.getElementById("javascript").textContent = $("#info").data("html");
$("#alert").click(function() { alert($("#info").data("html")) });

Here's a running example: /

There should be some method of setting the html of one element as the text of another while preserving newlines properly.

Is this possible with "text" or "textContent"? Is there an alternative way to do this? Is there a simple workaround? A less than simple workaround?

• javascript
• jquery
• html

• 3 With "newlines", you mean the br elements? Or actual new line characters in the HTML (which are not rendered anyway). Maybe you are looking for using .html instead of .text to set the content. From the .text documentation: "We need to be aware that this method escapes the string provided as necessary so that it will render correctly in HTML", which is what happens with <br>. – Felix Kling Commented Jan 10, 2014 at 0:15
• No, not looking for ".html". I'm very specifically looking to set the html of one element as the text of another. Honestly, the text. – Michael Plotke Commented Jan 10, 2014 at 0:18
• well you are grabbing HTML and the new lines are represented via HTML (br). Not \r or \n, so when you do .text it will strip all the br tags. You can try and replace all <br>'s with something temporarily and the switch them back after you move the text/html. Also depending on what type of element you are moving it into will depend on how you can get your line breaks back. – user2453734 Commented Jan 10, 2014 at 0:25
• The thought I'm playing with currently is using str.split("\n") first then arr.join("\n") later. – Michael Plotke Commented Jan 10, 2014 at 0:27
• sure or do str.replace('\n','!~![somethingunique]') then do the opposite after setting the other elements text value. Many options available you just have to know how the newline is being represented in the string you are manipulating becauase it could be str.split("<br>"). – user2453734 Commented Jan 10, 2014 at 0:28

As you've already determined, Web browsers don't normally render newline characters \n as line breaks. If you're resistent to adding the line break element <br />, you can use the white-space CSS property with the value pre-line, which will:

Sequences of whitespace are collapsed. Lines are broken at newline characters, at <br>, and as necessary to fill line boxes.

Be sure to check the property's patibility tables before using.

<div style="white-space: pre-line;">
    Look

    at
    these line breaks!
</div>
