Change values of text area

Question

There is a text-area where user put some text with 'new lines character', for example:

aaa
bbb

ccc

I would like to copy the value from this textarea to the input but there is a need to keep an information about new lines.

I want to replace new lines with some special separator like NEW_LINE and then decode it on the backend but something doesn't work, my code is:

var valueFromTextarea = $("#myTextarea").val();
valueFromTextarea .replace(/\n/g,"NEW_LINE");
$("#myTextarea-input").val(valueFromTextarea );

for this code the value of myTextarea-input is just aaabbbccc .

How is it possible to resolve that problem?

Answer 1

The replace method returns the modified value. It doesn't mutate the string (strings are immutable).

You need to pass its return value to val() .
