Prohibit JavaScript code from submitting forms with spaces

When I was working on the project, I used ckeditor on a page, but the problem came. I press the Enter key in the text box to automatically refresh the page. Finally, I found a solution:
Copy codeThe Code is as follows:
<Input type = "text" name = "mes. mesTitle "value =" <s: property value = 'mes. mesTitle '/> "class =" InputStyle "onkeydown =" keydown (this )"

It is as long as it is bound to each input text box, the onkeydown () event. js Code determines whether it is 13. The Code is as follows:
Copy codeThe Code is as follows:
Function keydown (text ){
$ J (text). keydown (function (e ){
If (e. which = 13 ){
E. preventDefault ();
}
});
}

I use jquery. Because we often use event Events and are incompatible with other browsers, we can use jquery's which to use a variety of browsers.
