jquery replacement method for line wrapping in textarea

Yesterday when colleagues were learning jquery, they wanted to use the swap line in the textarea.

HTML section:

1 2 3 4

<fieldset> <textarea id= "ncontent" ></textarea> </fieldset> <button id= "Submit" > Submit < /button>

JS section:

1 2 3 4 5 6 7 8 9

$ (document). Ready (function () {$ ("#submit"). Click (function () {var SS = $ ("#ncontent"). Text (); alert (ss); var str = Ss.replace (//R/N/GI, "!!!"); alert (str); }); }); </script>

After using the Replace () method of JavaScript, the newline is still not replaced.

The problem is getting the value in jquery to get textarea. should use

Copy code code as follows: var SS = $ ("#ncontent"). html ();

Using the text () or Val () method, the HTML tags in the textarea are processed, so it's definitely not a/r/n.
