As silly as it may sound, I still haven't found an appropriate answer.
Let's say I want to dynamically create a new DOM element and fill up its textContent/innerText
with a JS string literal.
The string is so long I would like to split it into three chunks:
var h1 = document.createElement("h1");
h1.textContent = "This is a very long string and I would like to insert a carriage return HERE...
moreover, I would like to insert another carriage return HERE...
so this text will display in a new line";
The problem is, if i write
h1.textContent = "...I would like to insert a carriage return here... \n";
it doesn't work, probably because the browser considers the '\n' to be pure text and displays it as such (the \r doesn't work either).
On the other hand, I could change the h1.innerHTML instead of the textContent and write:
h1.innerHTML = "...I would like to insert a carriage return here...<br />";
Here the <br /> would do the job, but doing so would replace not just the text content but all the HTML content of my h1, which is not quite what I want.
Is there a simple way to solve my problem?
I wouldn't resort to creating multiple block elements just to have the text on different lines.
Any idea would be greatly appreciated.
Thanks in advance.
I know this question posted long time ago.
I had similar problem few days ago, passing value from web service in json
format and place it in table
cell
contentText
.
Because value is passed in format, for example, "text row1\r\ntext row2"
and so on.
For new line in textContent
You have to use \r\n
and, finally, I had to use css white-space: pre-line;
(Text will wrap when necessary, and on line breaks) and everything goes fine.
Or, You can use only white-space: pre;
and then text will wrap only on line breaks (in this case \r\n
).
So, there is example how to solve it with wrapping text only on line breaks :
var h1 = document.createElement("h1");
//setting this css style solving problem with new line in textContent
h1.setAttribute('style', 'white-space: pre;');
//add \r\n in text everywhere You want for line-break (new line)
h1.textContent = "This is a very long string and I would like to insert a carriage return \r\n...";
h1.textContent += "moreover, I would like to insert another carriage return \r\n...";
h1.textContent += "so this text will display in a new line";
document.body.appendChild(h1);
