Question

I call

element.focus();

Where element is HTMLInputElement of type=button.
But then the browser clicks the button! That’s in mozilla and chrome.

How do i highlight the button with selection, but not initiate the click event?

Answer 1

Well, i’ve identified the reason.
I was handling the onkeydown event for Enter key.
The solution is to use
e.preventDefault();

function ConvertEnterToTab(s, e, numSkipElements) {
            var keyCode = e.keyCode || e.htmlEvent.keyCode;
            if (keyCode === 13) {
                var tabIndex = s.tabIndex || s.inputElement.tabIndex;
                if (numSkipElements == undefined) {
                    numSkipElements = 0;
                }

                var nextElement = FindNextElementByTabIndex(tabIndex + numSkipElements);
                if (nextElement != undefined) {
                    nextElement.focus();
                    return e.preventDefault ? e.preventDefault() : e.htmlEvent.preventDefault(); // this is the solution
                }
            }
        }

        function FindNextElementByTabIndex(currentTabIndex, maxTabIndex) {
            if (maxTabIndex == undefined) {
                maxTabIndex = 100;
            }

            var tempIndex = currentTabIndex + 1;
            while (!$('[tabindex='+ tempIndex+ ']')[0] || tempIndex === maxTabIndex) {
                tempIndex++;
            }

            return $('[tabindex=' + tempIndex + ']')[0];
        }
