How to add a new line in textarea element?
Solution 1:
Try this one:
<textarea cols='60' rows='8'>This is my statement one. This is my statement2</textarea>
Line Feed and
Carriage Return are HTML entitieswikipedia. This way you are actually parsing the new line ("\n") rather than displaying it as text.
Solution 2:
Break enter Keyword line in Textarea using CSS:
white-space: pre-wrap;
Solution 3:
I think you are confusing the syntax of different languages.
is (the HtmlEncoded value of ASCII 10 or) the linefeed character literal in a HTML string. But the line feed character does NOT render as a line break in HTML (see notes at bottom).\n
is the linefeed character literal (ASCII 10) in a Javascript string.<br/>
is a line break in HTML. Many other elements, eg<p>
,<div>
, etc also render line breaks unless overridden with some styles.
Hopefully the following illustration will make it clearer:
T.innerText = "Position of LF: " + t.value.indexOf("\n");
p1.innerHTML = t.value;
p2.innerHTML = t.value.replace("\n", "<br/>");
p3.innerText = t.value.replace("\n", "<br/>");
<textarea id="t">Line 1 Line 2</textarea>
<p id='T'></p>
<p id='p1'></p>
<p id='p2'></p>
<p id='p3'></p>
A few points to note about Html:
- The
innerHTML
value of theTEXTAREA
element does not render Html. Try the following:<textarea>A <a href='x'>link</a>.</textarea>
to see. - The
P
element renders all contiguous white spaces (including new lines) as one space. - The LF character does not render to a new line or line break in HTML.
- The
TEXTAREA
renders LF as a new line inside the text area box.
Solution 4:
I've found String.fromCharCode(13, 10)
helpful when using view engines.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/fromCharCode
This creates a string with the actual newline characters in it and so forces the view engine to output a newline rather than an escaped version. Eg: Using NodeJS EJS view engine - This is a simple example in which any \n should be replaced:
viewHelper.js
exports.replaceNewline = function(input) {
var newline = String.fromCharCode(13, 10);
return input.replaceAll('\\n', newline);
}
EJS
<textarea><%- viewHelper.replaceNewline("Blah\nblah\nblah") %></textarea>
Renders
<textarea>Blah
blah
blah</textarea>
replaceAll:
String.prototype.replaceAll = function (find, replace) {
var result = this;
do {
var split = result.split(find);
result = split.join(replace);
} while (split.length > 1);
return result;
};
