How to Submit textarea comment on Enter key?

This is not really CodeIgniter related, but more a jquery thing...

You could try if this works:

Code:

$("#commentbox").keyup(function(event) {

    if (event.which == 13) {
        event.preventDefault();
        alert("Submit!");

        $("#commentForm").submit();
    }
});

Basically, you forgot the '#' signs to tell jQuery to look for an ID, and the keypress handler (which I changed to a keyup..I read somewhere that's better for several reasons...Don't know if that's true, but it also doesn't hurt ) should be assigned to the commentbox, instead of the commentForm id.

Also, make sure this code is in your documents ready() function, like this:

Code:

$(document).ready(function(){

//code from above in here.

});
