Here is my jQuery for dynamic attached elements. The jq-select-ring button can be multiple on the DOM. Basically, it was attached through an Ajax call.
let cKeyTabShift = false;
$("body").on("keydown", ".jq-select-ring", function (e) {
if (!isMobileSite) {
var keyCode = (e.keyCode ? e.keyCode : e.which);
if (keyCode == 9) {
if (e.shiftKey) {
cKeyTabShift = true;
} else {
cKeyTabShift = false;
}
}
}
});
$("body").on("focusout", ".jq-select-ring", function () {
if (!isMobileSite) {
const parentIndex = $(this).closest('.flex-item').index();
const $elmSliders = $(this).closest('.container').find("div[id^='touchCarousel-'][role='tabpanel']");
const $nextArrow = $(this).closest('.touch-carousel').find('.touchcarousel-next');
const $prevArrow = $(this).closest('.touch-carousel').find('.touchcarousel-prev');
if (typeof ($elmSliders) != "undefined" && $elmSliders.length > 0) {
if ($elmSliders.length > 1) {
if (parentIndex == 1 && cKeyTabShift == false) {
if (!$nextArrow.hasClass('endArrows')) {
$nextArrow.trigger('click');
}
}
if (parentIndex == 0 && cKeyTabShift == true) {
if (!$prevArrow.hasClass('endArrows')) {
$prevArrow.trigger('click');
cKeyTabShift = false;
}
}
}
}
}
});
The issue is the trigger click is called when I add breakpoint only.
$nextArrow.trigger('click');
$prevArrow.trigger('click');

I have a javascript method in a partial view .Net 6 MVC like this: After upgrading to JQuery 3.6.1 and JQuery UI 1.13.2. I am getting errors like:

I'm making a custom dropdown and want to make good keyboard support. How do I get focus on my first LI when the UL visible. Didn't find answer by my self.
I take code from there https://codepen.io/beforesemicolon/pen/abNpjKo
On CodePen focus on first element works. But on my page - no... please, tell me if you know :)
Here is the code:
function DropDown(dropDown) {
const [toggler, menu] = dropDown.children;
const handleClickOut = e => {
if(!dropDown) {
return document.removeEventListener('click', handleClickOut);
}
if(!dropDown.contains(e.target)) {
this.toggle(false);
}
};
const setValue = (item) => {
const val = item.textContent;
toggler.textContent = val;
this.value = val;
this.toggle(false);
dropDown.dispatchEvent(new Event('change'));
toggler.focus();
}
const handleItemKeyDown = (e) => {
e.preventDefault();
if(e.keyCode === 38 && e.target.previousElementSibling) { // up
e.target.setAttribute("aria-selected", "false");
e.target.previousElementSibling.setAttribute("aria-selected", "true");
e.target.previousElementSibling.focus();
} else if(e.keyCode === 40 && e.target.nextElementSibling) { // down
e.target.setAttribute("aria-selected", "false");
e.target.nextElementSibling.setAttribute("aria-selected", "true");
e.target.nextElementSibling.focus();
} else if(e.keyCode === 27) { // escape key
this.toggle(false);
} else if(e.keyCode === 13 || e.keyCode === 32) { // enter or spacebar key
setValue(e.target);
}
}
const handleToggleKeyPress = (e) => {
e.preventDefault();
if(e.keyCode === 27) { // escape key
this.toggle(false);
} else if (e.keyCode === 13 || e.keyCode === 32) { // enter or spacebar key
this.toggle(true);
} else if (e.shiftKey && e.keyCode === 9) { // tab + shift key
this.toggle(false);
document.getElementById("message_email").focus();
} else if (e.keyCode === 9 ) { // tab key
this.toggle(false);
document.getElementById("message_text").focus();
}
}
toggler.addEventListener('keydown', handleToggleKeyPress);
toggler.addEventListener('click', () => this.toggle());
[...menu.children].forEach(item => {
item.addEventListener('keydown', handleItemKeyDown);
item.addEventListener('click', () => setValue(item));
});
this.element = dropDown;
this.value = toggler.textContent;
this.toggle = (expand = null) => {
expand = expand === null ? menu.getAttribute("aria-expanded") !== "true" : expand;
menu.setAttribute("aria-expanded", expand);
if(expand) {
menu.children[0].focus();
toggler.classList.add('active');
menu.children[0].focus();
document.addEventListener('click', handleClickOut);
dropDown.dispatchEvent(new Event('opened'));
//toggler.blur();
} else {
toggler.classList.remove('active');
toggler.focus();
dropDown.dispatchEvent(new Event('closed'));
document.removeEventListener('click', handleClickOut);
}
}
}
const dropDown = new DropDown(document.querySelector('.message__dropdown'));
Heh... problem was in CSS. Property {transition-duration} was written by me for UL (I mean for changing background color, but I didn't choose {transition-property}).
After I remove {transition-duration} focusing is working well. Oh my God... it tooks fore hours
This JavaScript function is working fine when I execute it through the debugger, but when I am not using the debugger, it's not executing:
function setColumnDisabled(){
var activeGrid = null;
var activeTab = tabbar1.getActiveTab();
if (activeTab == "a1") {
activeGrid = genInfo.mygrid;
}else if (activeTab == "a2") {
activeGrid = genInfo.mygrid2;
} else if (activeTab == "a21") {
activeGrid = genInfo.mygrid3;
} else if (activeTab == "a22") {
activeGrid = genInfo.mygrid3;
}else if(activeTab == "PartialTunnels"){
activeGrid = genInfo.partialObjectsGrid;
}
if(activeGrid != null){
activeGrid.forEachRow(function(row_id){
activeGrid.cellById(row_id,activeGrid.getColIndexById("Shared")).setDisabled(true);
});
}
}
Right now i have it to tab on enter but i would like to get it to ONLY enter the element when there is 11 characters. How would i do it?
function getNextElement(field) {
var form = field.form;
for ( var e = 0; e < form.elements.length; e++) {
if (field == form.elements[e]) {
break;
}
}
return form.elements[++e % form.elements.length];
}
function tabOnEnter(field, evt) {
if (evt.keyCode === 13) {
if (evt.preventDefault) {
evt.preventDefault();
} else if (evt.stopPropagation) {
evt.stopPropagation();
} else {
evt.returnValue = false;
}
getNextElement(field).focus();
return false;
} else {
return true;
}
}
Maybe just something simple like that:
if(field.value.length === 11)
getNextElement(field).focus();
I have the following code that works when triggered by an onclick for example: onClick="change('imgA');"
function change(v) {
var target = document.getElementById("target");
if (v == "imgA") {
target.className = "cast1";
} else if (v == "imgB") {
target.className = "cast2";
} else if (v == "imgC") {
target.className = "cast3";
} else if (v == "imgD") {
target.className = "cast4";
} else {
target.className = "chart";
}
}
as soon as this result is stored to the id 'target', How do I perform this same function again but with different classNames ('bio1' instead of 'cast1', etc). then save the results to a different id?
Everytime I've tried hasn't worked to this point.
You could try:
function change(v, id) {
var areas;
if( id == 'target' ) {
areas = 'cast';
} else {
areas = 'bio';
}
var target = document.getElementById(id);
if (v == "imgA") {target.className = areas+"1";}
else if (v == "imgB") {target.className = areas+"2";}
else if (v == "imgC") {target.className = areas+"3";}
else if (v == "imgD") {target.className = areas+"4";}
else {target.className = "chart";}
}
