The js code for the form is not allowed to submit Spaces

When I was working on the project, I used ckeditor on a page, but there was a problem, I pressed the enter key whenever there was a text box, and it would automatically refresh. Finally, I found a solution:

 
<input type="text" name="mes.mesTitle" value="<s:property value='mes.mesTitle'/>" class="InputStyle" onkeydown="keydown(this)" 

As long as in each input textbox binding,onkeydown() event. Js code is 13.

 
function keydown(text){ 
$j(text).keydown(function(e){ 
if(e.which==13){ 
e.preventDefault(); 
} 
}); 
} 

I use jquery. Because most of the time, we use event event, which is not compatible with other browsers, so using jquery which can be used for all kinds of browsers
