Question

document.onkeydown = function(event) {
    var tagName = event.target.tagName;
    if (tagName != 'INPUT' && tagName != 'TEXTAREA' && !event.alt && event.control) {

        if (event.ctrlKey && event.keyCode == 37) {
            if (_this.currentPage > 1) {
                window.location.href = _this.baseUrl.replace(/%page%/i, _this.currentPage + 1);
            }
        } else if (event.ctrlKey && event.keyCode == 39) {
            if (_this.currentPage < _this.pagesTotal) {
                window.location.href = _this.baseUrl.replace(/%page%/i, _this.currentPage - 1);
            }
        }
    }
}

This gives me an error only in IE 8:

‘target’ is null or not an object

for that line var tagName = event.target.tagName;

How to fix that? Error happens when I press Ctrl or arrows button.

Do it like this:

event = event || window.event;
var tagName = (event.target || event.srcElement).tagName.toUpperCase();
