Element on a menu not responding to a trigger event

I've made a menu that reveals a drop down menu when you click or touch it. At least that's what happens when you select the word 'Menu2' but unfortunately it's not what happens when you select the words 'Menu3'.
On Menu3, for some reason my code is not recognising the selection of the anchor element and then as a consequence the id of that anchor element is not being passed to the functions which will make the sub-menu appear and disappear.
The strangest thing is that when I replace the 'else if' statement with an 'if' statement the menu under 'Menu2' will appear when I select 'Menu3'!
The thing I took from this was that the querySelectorAll method and the For loop are working. It remains a mystery me why the third menu choice can't be selected.
My question is can anyone work why the menu below 'Menu3' is not opening and closing?
The listeners in the javascript code are activated when the window is loaded.
var timeout = 500;
var closetimer = 0;
var ddmenuitem = 0;
function listen(elem, evnt, func) {
if (elem.addEventListener) { //W3C DOMS.
elem.addEventListener(evnt, func, false);
} else if (elem.attachEvent) { //IE DOM 7
var r = elem.attachEvent("on" + evnt, func);
return r;
}
}
function attachListeners() {
var selectors = document.querySelectorAll("a#a2, a#a3");
for (var i = 0; i < selectors.length; i++) {
selectors[i].addEventListener("focus", function(event) {
var id_of_clicked_element = event.target.id
});
if (id_of_clicked_element = 'a2') {
var touch_div = document.getElementById(id_of_clicked_element);

I'd suggest a couple of things. First, like Leo Li suggested, I think you may have overcomplicated this a little. For instance, you could replace your attachListeners function with something like this:
function attachListeners() {
var selectors = document.querySelectorAll("a#a2, a#a3");
for (var i = 0; i < selectors.length; i++) {
selectors[i].addEventListener('touchstart', function(event){
event.preventDefault();
mopen(event.target.id);
}, false);
selectors[i].addEventListener('mouseover', function(event){
event.preventDefault();
mopen(event.target.id);
}, false);
selectors[i].addEventListener('click', function(event){
event.preventDefault();
mopen(event.target.id);
}, false);
}
}
But, besides that, one of the biggest problems is in the mopen() function. Instead of checking the value being passed in for x, you're reassigning it. Just switch the equals signs with triple equals, like this:
if (openmenu === 'a2') {
m1View();
} else if (openmenu === 'a3') {
m2View();
}
It's still probably not quite what you're looking for but here's a fork of your JSfiddle with my changes - https://jsfiddle.net/n90ryvfd/
Hope that helps!

How to create a shift key + mouse click event that would change the color of a black button to a yellow button on click? JavaScript

I am creating a minesweeper game and am trying to create an event where if the user holds down the shift key and left clicks their mouse simultaneously then the button (background-color is black) that I created for the field will turn yellow to indicate a button that is flagged. Here is what I have so far. The attribute ('data-value', 0) means that that button does not have a mine or number label that will indicate how far it is from the mine.
JS:
$('button').getAttribute('data-value', 0).getAttribute('data-x', j).getAttribute('data-y', i).getAttribute('data-visible', false).getAttribute('data-mine', false).click(function (e) {
if (e.shiftKey) {
$('button').addClass('flag');
}
});
CSS:
table td button {
background-color: black;
color: white;
width: 2em;
height: 2em;
}
.flag {
background-color: yellow;
}
Thank you for your help.

If you are not able to detect the key combination you can use the following script to do that, see below code try pressing SHIFT+ mouse left click to detect it.
let ShiftOn = false;
$(document).ready(function() {
$(document).keydown(function(e) {
let isShiftOn = e.which == "16";
(isShiftOn) && (ShiftOn = true);
}).keyup(function() {
ShiftOn = false;
});
$("#detectable-area").on('click', function() {
(ShiftOn) && console.log('SHIFT +LEFT Click');
});
});
div#detectable-area {
width: 100%;
height: 250px;
background: #c8c8c8;
vertical-align: middle;
text-align: center;
line-height: 250px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="detectable-area">Press SHIFT + click anywhere in the div to detect.</div>

Hovering Option in Select-field not working [duplicate]

I am trying to show a description when hovering over an option in a select list, however, I am having trouble getting the code to recognize when hovering.
Relevant code:
Select chunk of form:
<select name="optionList" id="optionList" onclick="rankFeatures(false)" size="5"></select>
<select name="ranks" id="ranks" size="5"></select>
Manipulating selects (arrays defined earlier):
function rankFeatures(create) {
var $optionList = $("#optionList");
var $ranks = $("#ranks");
if(create == true) {
for(i=0; i<5; i++){
$optionList.append(features[i]);
};
}
else {
var index = $optionList.val();
$('#optionList option:selected').remove();
$ranks.append(features[index]);
};
}
This all works. It all falls apart when I try to deal with hovering over options:
$(document).ready(
function (event) {
$('select').hover(function(e) {
var $target = $(e.target);
if($target.is('option')) {
alert('yeah!');
};
})
})
I found that code while searching through Stack Exchange, yet I am having no luck getting it to work. The alert occurs when I click on an option. If I don't move the mouse and close the alert by hitting enter, it goes away. If I close out with the mouse a second alert window pops up. Just moving the mouse around the select occasionally results in an alert box popping up.
I have tried targeting the options directly, but have had little success with that. How do I get the alert to pop up if I hover over an option?

You can use the mouseenter event.
And you do not have to use all this code to check if the element is an option.
Just use the .on() syntax to delegate to the select element.
$(document).ready(function(event) {
$('select').on('mouseenter','option',function(e) {
alert('yeah');
// this refers to the option so you can do this.value if you need..
});
});
Demo at http://jsfiddle.net/AjfE8/

try with mouseover. Its working for me. Hover also working only when the focus comes out from the optionlist(like mouseout).
function (event) {
$('select').mouseover(function(e) {
var $target = $(e.target);
if($target.is('option')) {
alert('yeah!');
};
})
})

You don't need to rap in in a function, I could never get it to work this way. When taking it out works perfect. Also used mouseover because hover is ran when leaving the target.
$('option').mouseover(function(e) {
var $target = $(e.target);
if($target.is('option')) {
console.log('yeah!');
};
})​
Fiddle to see it working. Changed it to console so you don't get spammed with alerts. http://jsfiddle.net/HMDqb/

That you want is to detect hover event on option element, not on select:
$(document).ready(
function (event) {
$('#optionList option').hover(function(e) {
console.log(e.target);
});
})​

I have the same issue, but none of the solutions are working.
$("select").on('mouseenter','option',function(e) {
$("#show-me").show();
});
$("select").on('mouseleave','option',function(e) {
$("#show-me").hide();
});
$("option").mouseover(function(e) {
var $target = $(e.target);
if($target.is('option')) {
alert('yeah!');
};
});
Here my jsfiddle https://jsfiddle.net/ajg99wsm/

I would recommend to go for a customized variant if you like to ease
capture hover events
change hover color
same behavior for "drop down" and "all items" view
plus you can have
resizeable list
individual switching between single selection and multiple selection mode
more individual css-ing
multiple lines for option items
Just have a look to the sample attached.
$(document).ready(function() {
$('.custopt').addClass('liunsel');
$(".custopt, .custcont").on("mouseover", function(e) {

Jquery Drag to Delete

I am currently playing with some jquery and as i tried to create a simple todo-list I came across a problem.
So far the goal is to be able to add paragraphs by clicking the green square and remove them by clicking it once and then dragging it to the red square.
Everything works out fine except the deleting of the dragged paragraph.
Right now it only works by removing the whole class but I want to only delete the dragged one.
Here the code: https://codepen.io/anon/pen/OXXXpY
jQuery:
$(document).ready(function() {
var send = $("#send");
var dlt = $("#delete");
send.click(function() {
var input = $("input").val();
$("#container").prepend("<p class='entry'>" + input + "</p>");
});
$(document).on("click", ".entry", function() {
$(this).draggable();
$("#delete").droppable({
drop: function() {$(".entry").remove();}
});
});
});
Please don't mind my English and the real use of this project. This is just an jQuery experiment.

Use $(this) to target the dragged element
$(document).on("click", ".entry", function() {
var $this = $(this);
$(this).draggable();
$("#delete").droppable({
drop: function() {
$($this).remove();
}
});
});
$(document).ready(function() {
var send = $("#send");
var dlt = $("#delete");
send.click(function() {
var input = $("input").val();
$("#container").prepend("<p class='entry'>" + input + "</p>");
});
$(document).on("click", ".entry", function() {
var $this = $(this);
$(this).draggable();
$("#delete").droppable({
drop: function() { $($this).remove(); }
});
});
});

Replace selection inputs with clickable images

MY code below lets me take an HTML selection and provide a more user friendly image clickable version. When an image is clicked, it selects the proper value in a hidden selection filed in the DOM.
I just need help in adjusting my code below to work on a selection that is on the page multiple times.
If it is on the page 10 times, I need to run this code 10 times.
I am not sure how to target each one separately though
Preview
HTML Selection gets turned into clickable Images like this below. The JavaScript reads the HTML Selection filed already on the page and clones it and replaces each value with images. It then hides the original selection field. When an image is clicked on, and appears selected, it is using JavaScript to select that value in the real hidden selector as well!...

First, you need to change the page_template and page_template_visual ids to classes (in the HTML, JavaScript & CSS).
Then loop through all the elements with the page_template class, like this:
jQuery(document).ready(function($) {
$('.page_template').each(function() {
var $select = $(this);
// Keep a reference to this element so you can use it below.
var $visual = $('<div class="page_template_visual"></div>');
$select.after($visual);
$select.find('option').each(function() {
var $option = $(this);
var classname = $option.val().replace('.php', '');
if ($option.is("[selected]")) {
classname = classname + ' selected';
}
$visual.append('<small></small>' + $option.text() + '');
});
if (!$select.find('option[selected]').length) {
$visual.find('a:first-child').addClass('selected');
}
// The next line could have been:
// $visual.find('a').on('click', function() {
// But instead it uses event delegation, so only one
// event handler is registered, instead of one for each <a>.
$visual.on('click', 'a', function() {
$visual.find('a').removeClass('selected');
var value = $(this).addClass('selected').attr('href');
$select.val(value);
return false; // You don't need this, unless you really don't want the click event to bubble up.
});
});
});
