Have this code and tried to hide my side navbar when clicked outside the #nav, got this error.
Cannot read property 'addEventListener' of null
$( document ).ready( function() {
setTimeout(function(){
$('.menu-opener').click(function(){
$('#nav').toggleClass('active');
});
let slide = document.querySelector('#nav .active');
slide.addEventListener('click', function(e) {
if (e.target !== slide) return;
$('#nav').removeClass('active');
});
}, 1000);
});
answer is that you need to detect click outside of div you are trying to hide:
$(window).click(function() {
//Hide the menus if visible
});
//stopping above function from running when clicking on #nav itself
$('#nav').click(function(event){
event.stopPropagation();
});
Try this inside setTimeout
$('body').on('click','#nav .active', function(e){
// your logic
})
OR
$( "'#nav .active'" ).bind( "click", function(e) {
// your logic
});
instead of
let slide = document.querySelector('#nav .active');
slide.addEventListener('click', function(e) {
if (e.target !== slide) return;
$('#nav').removeClass('active');
});
Got this working with
$(document).click(function(event) {
if(!$(event.target).closest('#nav').length && !$(event.target).closest(".menu-opener").length)
{
$('#nav').removeClass('active');
}
});
I've used simple jQuery UI tooltip on form-fields of my webpage(viz responsive), its working perfectly on desktop on every browser, but on iPad its get distorted when I tap on form-fields as keypad swipe-up. Also header section of my webpage gets fixed on scroll.
I've used below code for the custom jQuery Tooltip.
$(function () {
$('.form-control').tooltip({
disabled: true,
position: {
my: "left top",
at: "left top-50",
using: function( position, feedback ) {
$( this ).css( position );
$( "<div>" )
.addClass( "arrow" )
.addClass( feedback.vertical )
.addClass( feedback.horizontal )
.appendTo( this );
}
}
}).on("focusin", function () {
$(this)
.tooltip("enable")
.tooltip("open");
}).on("focusout", function () {
$(this)
.tooltip("close")
.tooltip("disable");
});
});
I've written this code to re-initialize the tooltip for the focused field by calling its focusin trigger manually when document size changed. It is working as expected on Desktop browsers but on iPad tooltip is being re-initialized at same place again viz incorrect.
var toolTipEl;
$('#inputSuccess, #inputWarning').tooltip({
open: function (event, ui) {
toolTipEl = event.target;
}
});
function checkDocumentHeight(callback){
var lastHeight = document.body.clientHeight, newHeight, timer;
(function run(){
newHeight = document.body.clientHeight;
if( lastHeight != newHeight )
callback();
lastHeight = newHeight;
timer = setTimeout(run, 100);
})();
}
function doSomthing(){
console.log('document resized');
setTimeout(function() {
if ($(toolTipEl).is(':focus')) {
$(toolTipEl).trigger('focusout').trigger('focusin');
}
}, 500);
}
checkDocumentHeight(doSomthing);
Please help me to find out the solution for this.
You will need to reinitialize active Tooltip after completion of any event which cause change in the content (actually height) of your document affecting your Tooltip position.
First keep reference of the element for which the tooltip is active by listening to its events by adding following codes in your tooltip initialization (Keep your existing code as it is. Just add these additional statements).
var toolTipEl = undefined;
$(function () {
$('.form-control').tooltip({
open: function (event, ui) {
toolTipEl = event.target;
}
}).on("focusin", function () {
toolTipEl = undefined;
}).on("focusout", function () {
toolTipEl = undefined;
}).on("mouseleave", function () {
toolTipEl = undefined;
});
});
Please note, as you are displaying tooltip on focusin event as well. So, you will also need to release the variable if you do not want tooltip pop-upped if focus has changed/left.
And then create a function for resetting tooltip like below.
function resetTooltip() {
if (toolTipEl) {
$(toolTipEl).trigger('focusout').trigger('focusin');
};
}
Call this function in any events which is causing change in the document height. For example if content is coming from an ajax request. You can call restTooltip function by listing to the gloab ajax events. See example below.
$( document ).ajaxComplete(function() {
resetTooltip();
});
I hope it will help you. Ask me if you need any further clarification.
As it stands the remove function doesn't work. Any suggestions?
var toggle = new function() {
$(document).on('click', 'img', function () {
$(this).parent().toggle('slide');
})
}
var remove = new function() {
$(document).on('click', 'img',
setTimeout(function () {
$(this).parent().remove();
}, 1000);
)
}
The function your are looking for is .queue(). It will execute a provided callback after the previous animation has finished:
$(document).on('click', 'img', function() {
var $entry = $(this).parent();
$entry.toggle('slide').queue(function(next) {
$entry.remove();
next();
});
});

I have a draggable <div> with a click event and without any event for drag,
but after I drag <div> the click event is apply to <div>.
How can prevent of click event after drag?
$(function(){
$('div').bind('click', function(){
$(this).toggleClass('orange');
});
$('div').draggable();
});
http://jsfiddle.net/prince4prodigy/aG72R/
FIRST attach the draggable event, THEN the click event:
$(function(){
$('div').draggable();
$('div').click(function(){
$(this).toggleClass('orange');
});
});
Try it here:
http://jsfiddle.net/aG72R/55/
With an ES6 class (No jQuery)
To achieve this in javascript without the help of jQuery you can add and remove an event handler.
First create functions that will be added and removed form event listeners
flagged () {
this.isScrolled = true;
}
and this to stop all events on an event
preventClick (event) {
event.preventDefault();
event.stopImmediatePropagation();
}
Then add the flag when the mousedown and mousemove events are triggered one after the other.
element.addEventListener('mousedown', () => {
element.addEventListener('mousemove', flagged);
});
Remember to remove this on a mouse up so we don't get a huge stack of events repeated on this element.
element.addEventListener('mouseup', () => {
element.removeEventListener('mousemove', flagged);
});
Finally inside the mouseup event on our element we can use the flag logic to add and remove the click.
element.addEventListener('mouseup', (e) => {
if (this.isScrolled) {
e.target.addEventListener('click', preventClick);
} else {
e.target.removeEventListener('click', preventClick);
}
this.isScrolled = false;
element.removeEventListener('mousemove', flagged);
});
In the above example above I am targeting the real target that is clicked, so if this were a slider I would be targeting the image and not the main gallery element. to target the main element just change the add/remove event listeners like this.
element.addEventListener('mouseup', (e) => {
if (this.isScrolled) {
element.addEventListener('click', preventClick);
} else {
element.removeEventListener('click', preventClick);
}
this.isScrolled = false;
element.removeEventListener('mousemove', flagged);
});
Conclusion
By setting anonymous functions to const we don't have to bind them. Also this way they kind of have a "handle" allowing s to remove the specific function from the event instead of the entire set of functions on the event.
I made a solution with data and setTimeout. Maybe better than helper classes.
<div id="dragbox"></div>
and
$(function(){
$('#dragbox').bind('click', function(){
if($(this).data('dragging')) return;
$(this).toggleClass('orange');
});
$('#dragbox').draggable({
start: function(event, ui){
$(this).data('dragging', true);
},
stop: function(event, ui){
setTimeout(function(){
$(event.target).data('dragging', false);
}, 1);
}
});
});
Check the fiddle.
This should work:
$(function(){
$('div').draggable({
start: function(event, ui) {
$(this).addClass('noclick');
}
});
$('div').click(function(event) {
if ($(this).hasClass('noclick')) {
$(this).removeClass('noclick');
}
else {
$(this).toggleClass('orange');
}
});
});
DEMO
You can do it without jQuery UI draggable. Just using common 'click' and 'dragstart' events:
$('div').on('dragstart', function (e) {
e.preventDefault();
$(this).data('dragging', true);
}).on('click', function (e) {
if ($(this).data('dragging')) {
e.preventDefault();
$(this).data('dragging', false);
}
});
You can just check for jQuery UI's ui-draggable-dragging class on the draggable. If it's there, don't continue the click event, else, do. jQuery UI handles the setting and removal of this class, so you don't have to. :)
Code:
$(function(){
$('div').bind('click', function(){
if( $(this).hasClass('ui-draggable-dragging') ) { return false; }
$(this).toggleClass('orange');
});
$('div').draggable();
});
With React
This code is for React users, checked the draggedRef when mouse up.
I didn`t use click event. The click event checked by the mouse up event.
const draggedRef = useRef(false);
...
<button
type="button"
onMouseDown={() => (draggedRef.current = false)}
onMouseMove={() => (draggedRef.current = true)}
onMouseUp={() => {
if (draggedRef.current) return;
setLayerOpened(!layerOpened);
}}
>
BTN
</button>
I had the same problem (tho with p5.js) and I solved it by having a global lastDraggedAt variable, which was updated when the drag event ran. In the click event, I just checked if the last drag was less than 0.1 seconds ago.
function mouseDragged() {
// other code
lastDraggedAt = Date.now();
}
function mouseClicked() {
if (Date.now() - lastDraggedAt < 100)
return; // its just firing due to a drag so ignore
// other code
}
I have elements on the page which are draggable with jQuery. Do these elements have click event which navigates to another page (ordinary links for example).
What is the best way to prevent click from firing on dropping such element while allowing clicking it is not dragged and drop state?
I have this problem with sortable elements but think it is good to have a solution for general drag and drop.
I've solved the problem for myself. After that I found that same solution exists for Scriptaculous, but maybe someone has a better way to achieve that.
A solution that worked well for me and that doesn't require a timeout: (yes I'm a bit pedantic ;-)
I add a marker class to the element when dragging starts, e.g. 'noclick'. When the element is dropped, the click event is triggered -- more precisely if dragging ends, actually it doesn't have to be dropped onto a valid target. In the click handler, I remove the marker class if present, otherwise the click is handled normally.
$('your selector').draggable({
start: function(event, ui) {
$(this).addClass('noclick');
}
});
$('your selector').click(function(event) {
if ($(this).hasClass('noclick')) {
$(this).removeClass('noclick');
}
else {
// actual click event code
}
});
Solution is to add click handler that will prevent click to propagate on start of drag. And then remove that handler after drop is performed. The last action should be delayed a bit for click prevention to work.
Solution for sortable:
...
.sortable({
...
start: function(event, ui) {
ui.item.bind("click.prevent",
function(event) { event.preventDefault(); });
},
stop: function(event, ui) {
setTimeout(function(){ui.item.unbind("click.prevent");}, 300);
}
...
})
Solution for draggable:
...
.draggable({
...
start: function(event, ui) {
ui.helper.bind("click.prevent",
function(event) { event.preventDefault(); });
},
stop: function(event, ui) {
setTimeout(function(){ui.helper.unbind("click.prevent");}, 300);
}
...
})
I had the same problem and tried multiple approaches and none worked for me.
Solution 1
$('.item').click(function(e)
{
if ( $(this).is('.ui-draggable-dragging') ) return false;
});
does nothing for me. The item is being clicked after the dragging is done.
Solution 2 (by Tom de Boer)
$('.item').draggable(
{
stop: function(event, ui)
{
$( event.originalEvent.target).one('click', function(e){ e.stopImmediatePropagation(); } );
}
});
This works just fine but fails in one case- when I was going fullscreen onclick:
var body = $('body')[0];
req = body.requestFullScreen || body.webkitRequestFullScreen || body.mozRequestFullScreen;
req.call(body);
Solution 3 (by Sasha Yanovets)
$('.item').draggable({
start: function(event, ui) {
ui.helper.bind("click.prevent",
function(event) { event.preventDefault(); });
},
stop: function(event, ui) {
setTimeout(function(){ui.helper.unbind("click.prevent");}, 300);
}
})
This does not work for me.
Solution 4- the only one that worked just fine
$('.item').draggable(
{
});
$('.item').click(function(e)
{
});
Yep, that's it- the correct order does the trick- first you need to bind draggable() then click() event. Even when I put fullscreen toggling code in click() event it still didn't go to fullscreen when dragging. Perfect for me!
I'd like to add to this that it seems preventing the click event only works if the click event is defined AFTER the draggable or sortable event. If the click is added first, it gets activated on drag.
I don't really like to use timers or preventing, so what I did is this:
var el, dragged
el = $( '#some_element' );
el.on( 'mousedown', onMouseDown );
el.on( 'mouseup', onMouseUp );
el.draggable( { start: onStartDrag } );
onMouseDown = function( ) {
dragged = false;
}
onMouseUp = function( ) {
if( !dragged ) {
console.log('no drag, normal click')
}
}
onStartDrag = function( ) {
dragged = true;
}
Rocksolid..
lex82's version but for .sortable()
start: function(event, ui){
ui.item.find('.ui-widget-header').addClass('noclick');
},
and you may only need:
start: function(event, ui){
ui.item.addClass('noclick');
},
and here's what I'm using for the toggle:
$("#datasign-widgets .ui-widget-header").click(function(){
if ($(this).hasClass('noclick')) {
$(this).removeClass('noclick');
}
else {
$(this).next().slideToggle();
$(this).find('.ui-icon').toggleClass("ui-icon-minusthick").toggleClass("ui-icon-plusthick");
}
});
A possible alternative for Sasha's answer without preventing default:
var tmp_handler;
.sortable({
start : function(event,ui){
tmp_handler = ui.item.data("events").click[0].handler;
ui.item.off();
},
stop : function(event,ui){
setTimeout(function(){ui.item.on("click", tmp_handler)}, 300);
},
In jQuery UI, elements being dragged are given the class "ui-draggable-dragging".
We can therefore use this class to determine whether to click or not, just delay the event.
You don't need to use the "start" or "stop" callback functions, simply do:
$('#foo').on('mouseup', function () {
if (! $(this).hasClass('ui-draggable-dragging')) {
// your click function
}
});
This is triggered from "mouseup", rather than "mousedown" or "click" - so there's a slight delay, might not be perfect - but it's easier than other solutions suggested here.
In my case it worked like this:
$('#draggable').draggable({
start: function(event, ui) {
$(event.toElement).one('click', function(e) { e.stopPropagation(); });
}
});
After reading through this and a few threads this was the solution I went with.
var dragging = false;
$("#sortable").mouseover(function() {
$(this).parent().sortable({
start: function(event, ui) {
dragging = true;
},
stop: function(event, ui) {
// Update Code here
}
})
});
$("#sortable").click(function(mouseEvent){
if (!dragging) {
alert($(this).attr("id"));
} else {
dragging = false;
}
});
the most easy and robust solution? just create transparent element over your draggable.
.click-passthrough {
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
background: transparent;
}
element.draggable({
start: function () {
},
drag: function(event, ui) {
// important! if create the 'cover' in start, then you will not see click events at all
if (!element.find('.click-passthrough').length) {
element.append("<div class='click-passthrough'></div>");
}
},
stop: function() {
// remove the cover
element.find('.click-passthrough').remove();
}
});
Have you tried disabling the link using event.preventDefault(); in the start event and re-enabling it in the drag stopped event or drop event using unbind?
Just a little wrinkle to add to the answers given above. I had to make a div that contains a SalesForce element draggable, but the SalesForce element has an onclick action defined in the html through some VisualForce gobbledigook.
Obviously this violates the "define click action after the drag action" rule, so as a workaround I redefined the SalesForce element's action to be triggered "onDblClick", and used this code for the container div:
$(this).draggable({
zIndex: 999,
revert: true,
revertDuration: 0,
start: function(event, ui) {
$(this).addClass('noclick');
}
});
$(this).click(function(){
if( $(this).hasClass('noclick'))
{
$(this).removeClass('noclick');
}
else
{
$(this).children(":first").trigger('dblclick');
}
});
The parent's click event essentially hides the need to double-click the child element, leaving the user experience intact.
I tried like this:
var dragging = true;
$(this).click(function(){
if(!dragging){
do str...
}
});
$(this).draggable({
start: function(event, ui) {
dragging = true;
},
stop: function(event, ui) {
setTimeout(function(){dragging = false;}, 300);
}
});
for me helped passing the helper in options object as:
.sortable({
helper : 'clone',
start:function(),
stop:function(),
.....
});
Seems cloning dom element that is dragged prevented the bubbling of the event. I couldn´t avoid it with any eventPropagation, bubbling, etc. This was the only working solution for me.
The onmousedown and onmouseup events worked in one of my smaller projects.
var mousePos = [0,0];
function startClick()
{
mousePos = [event.clientX,event.clientY];
}
function endClick()
{
if ( event.clientX != mousePos[0] && event.clientY != mousePos[1] )
{
alert( "DRAG CLICK" );
}
else
{
alert( "CLICK" );
}
}
<img src=".." onmousedown="startClick();" onmouseup="endClick();" />
Yes, I know. Not the cleanest way, but you get the idea.
