jquery how to catch enter key and change event to

Question

I want a jquery solution, I must be close, what needs to be done?

$('html').bind('keypress', function(e)
{
     if(e.keyCode == 13)
     {
         return e.keyCode = 9; //set event key to tab
     }
});

I can return false and it prevents the enter key from being pressed, I thought I could just change the keyCode to 9 to make it tab but it doesn't appear to work. I've got to be close, what's going on?

Answer 1

$('input').live("keypress", function(e) {
            /* ENTER PRESSED*/
            if (e.keyCode == 13) {
                /* FOCUS ELEMENT */
                var inputs = $(this).parents("form").eq(0).find(":input:visible");
                var idx = inputs.index(this);

                if (idx == inputs.length - 1) {
                    inputs[0].select()
                } else {
                    inputs[idx + 1].focus(); //  handles submit buttons
                    inputs[idx + 1].select();
                }
                return false;
            }
        });

visible input cann't be focused.

I know this question is older than god, but I never saw an answer that was all that elegant.

doc.on('keydown', 'input', function(e, ui) {
    if(e.keyCode === 13){
        e.preventDefault();
        $(this).nextAll('input:visible').eq(0).focus();
    }
});

that seems to get the job done in as few lines as humanly possible.

I wrote the code from the accepted answer as a jQuery plugin, which I find more useful. (also, it now ignores hidden, disabled, and readonly form elements).

$.fn.enterAsTab = function () {
  $(this).find('input').live("keypress", function(e) {
    /* ENTER PRESSED*/
    if (e.keyCode == 13) {
        /* FOCUS ELEMENT */
        var inputs =   $(this).parents("form").eq(0).find(":input:visible:not(disabled):not([readonly])"),
            idx = inputs.index(this);

        if (idx == inputs.length - 1) {
            inputs[0].select()
        } else {
            inputs[idx + 1].focus(); // handles submit buttons
            inputs[idx + 1].select();
        }
        return false;
    }
  });
  return this;
};

This way I can do $('#form-id').enterAsTab(); ... Figured I'd post since no one has posted it as a $ plugin yet and they aren't entirely intuitive to write.

These solutions didn't work with my datagrid. I was hoping they would. I don't really need Tab or Enter to move to the next input, column, row or whatever. I just need Enter to trigger .focusout or .change and my datagrid updates the database. So I added the "enter" class to the relevant text inputs and this did the trick for me:

$(function() {
   if ($.browser.mozilla) {
        $(".enter").keypress(checkForEnter);
    } else {
        $(".enter").keydown(checkForEnter);
    }
});

function checkForEnter(event) {
    if (event.keyCode == 13) {
        $(".enter").blur();
    }
}

This works perfect!

 $('input').keydown( function(e) {
        var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
        if(key == 13) {
            e.preventDefault();
            var inputs = $(this).closest('form').find(':input:visible');
            inputs.eq( inputs.index(this)+ 1 ).focus();
        }
    });

Here is a solution :

$('input').on("keypress", function(e) {
            /* ENTER PRESSED*/
            if (e.keyCode == 13) {
                /* FOCUS ELEMENT */
                var inputs = $(this).parents("form").eq(0).find(":input");
                var idx = inputs.index(this);

                if (idx == inputs.length - 1) {
                    inputs[0].select()
                } else {
                    inputs[idx + 1].focus(); //  handles submit buttons
                    inputs[idx + 1].select();
                }
                return false;
            }
        });
