Using a hotkey to submit an HTML form?

I have a very simple HTML form, only containing a submit button and a textarea. Is there an easy way to use a hotkey to submit this form, as an alternative to pressing the button?

Thanks in 开发者_运维技巧advance :-)

Submit buttons can have accesskeys, but there are drawbacks. Users would probably be better off just hitting the tab key to focus the submit button, and then pressing enter.

you can use the "keyDown", "keyPress" events if you use a JS library (JQUERY or MOOTOOLS).. you can program your own Ctrl+S to submit.

On JQuery see this http://api.jquery.com/keypress/

On Mootools see this http://mootorial.com/wiki/mootorial/03-native/05-event

Here is the jQuery method for adding a keypress listener to your button (by specifying the ID)... you can also do it on your page by changing "YourID" to "document" (without quotes, since document is a page element. I know keypress has been mentioned, figured it would be easier for others to have code here, and not have to move elsewhere.

$("#YourID").keypress(function (e) {
   var code = (e.keyCode ? e.keyCode : e.which); // grabs keycode pressed
   if (code == 13) {  // Code 13 is enter
        searchUPC();
   }
});
