JQuery replaces the line feed method in textarea, jquerytextarea

This example describes how jQuery replaces the line feed in textarea. Share it with you for your reference. The specific analysis is as follows:

When my colleague learned jQuery yesterday, he hoped to replace the line feed in textarea.

Html section:

<Fieldset> <textarea id = "ncontent"> </textarea> </fieldset> <button id = "submit"> submit </button>

Js section:

$ (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 in JavaScript, the line feed is still not replaced.

The problem is that jQuery obtains the value in textarea. Should be used
Copy codeThe Code is as follows: var ss =$ ("# ncontent" pai.html ();

If the text () or val () method is used to process the html Tag in textarea, the/r/n cannot be replaced.

I hope this article will help you with jQuery programming.
