问题:

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 advance :-)

回答1:

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.

回答2:

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();
   }
});
