I have made a page using jquery, and on load it selects the first text field automatically. I want it to then move to the next field when the ENTER key is pressed.

Basically, you just need top have the DOM elements in some structure so that you can select the next one. I'd suggest exploiting tabindex, but anything that let's you have a defined order will work.

I've created a little function which can do what you need. This is the version I use so you may need to change the class names but you should get the idea.

<script type="text/javascript">
$(document).ready(function(){
$(".vertical").keypress(function(event) {
        if(event.keyCode == 13) { 
        textboxes = $("input.vertical");
        debugger;
        currentBoxNumber = textboxes.index(this);
        if (textboxes[currentBoxNumber + 1] != null) {
            nextBox = textboxes[currentBoxNumber + 1]
            nextBox.focus();
            nextBox.select();
            event.preventDefault();
            return false 
            }
        }
    });
})
</script>

So basically:-

Get all the input fields matching .vertical
Find which is the current text box
Find the next one
Set the focus on that one

You should use:
```
$(this).next('input').focus();  
```

try this:

(function($){
    $.fn.enterNext = function(){
       var _i =0;
       $('input[type=text], select',this)
            .each(function(index){
            _i = index;
            $(this)
                .addClass('tab'+index)
                .keydown(function(event){
                    if(event.keyCode==13){
                        $('.tab'+(index+1)).focus();
                        event.preventDefault();
                    }
                });

        })
     $( "input[type=submit]",this ).addClass('tab'+(_i+1));
}})(jQuery);

for use:

$('form.element').enterNext();

in my case this is the best solution in that I got because the function .next() is strict with elements outside their branch DOM. The best way is to force an index.

and sorry for my bad English...

Here is the solution I came up with. The issue I had was that I needed to maintain tabindex, i.e. it had to function exactly that same as hitting tab. It uses both underscore and jquery.

I've left in my debugging code:

try {
    var inputs = $("input[id^=tpVal-]");
    var sortedInputs = _.sortBy(inputs, function(element){
        var tabIndex = $(element).attr('tabindex');//debugging
        var id = $(element).attr('id');//debugging
        console.log(id +" | "+ tabIndex +" | "+ $(element));//debugging
        return parseInt($(element).attr('tabindex'));
    });
    $(sortedInputs).each(function (index, element) {
        $(element).keyup(function(event){
            if(event.keyCode==13) {
                var $thisElement = $(element);//debugging
                var nextIndex = index+1;//debugging
                var $nextElement = $(sortedInputs[nextIndex]);
                var thisId = $thisElement.attr('id');//debugging
                var nextId = $nextElement.attr('id');//debugging
                console.log("Advance from "+thisId+" to "+nextId);//debugging
                if($nextElement!=undefined) {
                    $(sortedInputs[index + 1]).focus();
                }
            }
        });
    });
} catch (e) {
    console.log(e);
}
