Menu
Order entry form contains product code and quantity columns in multiple rows and delete button (-) in end of every row. It contains also add button in first column and after form.
Pressing enter key should set focus to next text or numeric input field (product code or quantity), skipping buttons.
I tried code below is used but enter key is ignored.
Chrome debugger shows that line $(this).next('input').focus() is executed but
focus() call does not have any effect.
jquery, jquery-mobile, ASP.NET MVC4 are used

The problem is that the next input is sometimes a button. Here is a JS Fiddle with a possible solution:
http://jsfiddle.net/hxZSU/1/
I've added a data attribute to the html elements that are inputs for the user. The attribute also contains an incrementing index so that you can control the order of the elements receiving focus.
Here are the HTML changes:
<input class='ui-widget-content ui-corner-all form-fullwidth' data-index="1" id='Tasudok' name='Tasudok' value='' maxlength='25' />
<input type="text" name="Toode" class="my-input" data-index="2" />
<input type="number" name="Kogus" data-index="3" />
Here is the new JavaScript event that will move between the input fields. It will determine the index of the element is currently being edited by using $(event.target).attr('data-index'). It increments the index and selects the next element using this.
$('#inputform').on('keydown', 'input', function (event) {
if (event.which == 13) {
event.preventDefault();
var $this = $(event.target);
var index = parseFloat($this.attr('data-index'));
$('[data-index="' + (index + 1).toString() + '"]').focus();
}
});

function handleEnter(event) {
if (event.key==="Enter") {
const form = document.getElementById('form')
const index = [...form].indexOf(event.target);
form.elements[index + 1].focus();
//event.preventDefault();
}
}
