disable enter key in textarea on jsp

Question

I want to disable enter key in textarea on jsp but the function is not working and enter key still make new line when I press it.

Below is the function to disable enter key in textarea :

$("textarea").on("keypress", function(e) {
if ((e.keyCode == 13)) {
e.preventDefault();

    }
});

And there is the jsp :

<td><form:textarea path="connote.shipperAddr" id="shipperAddr" name="shipperAddr" onfocus="this.select();" onmouseup="return false;" onblur="whenEmpty(this);"
htmlEscape="true" 
rows="3" cols="34"
tabindex="5"/> <form:errors
path="connote.shipperAddr" cssClass="error" /></td>

How can I disable enter key from a textarea?

But it still not working – kumala nindya Jan 20 '16 at 05:08 — kumala nindya, Jan 20 '16 at 05:08

Your code is working fine. Demo

$("textarea").on("keypress", function(e) {
if ((e.keyCode == 13)) {
e.preventDefault();

    }
});

Please make sure your selector $(textarea) is able to get the textarea element.Is form:textarea rendered as normal <textarea></textarea>.

But I can't change the element because the element binds with the other function. – kumala nindya Jan 20 '16 at 05:59
Try using the id _"shipperAddr"_ as selector. Eg: `$("#shipperAddr")`. And also make sure you register this event as soon as page loads by including your script in `$(document).ready()`. – Raghu Jan 20 '16 at 06:03
