I am trying to have menu items click to open sub items and then double click to follow through to the link. Have tried a variety of different approaches but for some reason nothing's happening when double clicked.
$( ".site-head .section-menu .mobile-sub-menu ul li .first-a" ).on('click', function(event) {
$( ".sub-items" ).addClass('hiddenMenu');
$(this).parent().find('.sub-items').removeClass('hiddenMenu');
event.preventDefault();
});
$(document).on('dblclick', '.first-a', function() {
console.log("event fired");
window.location.replace($(this).attr("href"));
});
Any suggestions on what I'm doing wrong?
Edit: the standard solution that has been suggested doesn't work in this situation. The double click should direct to link and the first should prevent going to the link and execute some other function...
When you make the first click, don't immediately call the method, instead set a timer that calls the original callback function in say ~0.75 seconds UNLESS you receive a second click. You're firing off an event and handling the first click, so when the second click comes through - it's a single click, not a 'dblclick'
I hope this will help You..

It is not recommended to bind both click and doubleclick events to the same element, but if you must do so, this previously accepted answer provides a perfect solution by using a counter to track # of clicks: Jquery bind double click and single click separately

I want to nest one .click() event with another but its not working. I looked at the .on() event, but I don't think its what I need. Below is basically what I have so far, but its not working as intended.
I want to click on the 'adress1' button, get directed to the next page where I either click the 'profession1' button or the 'profession2' button, and depending on which of the last two buttons is clicked, something respective happens.
//HTML code for first button
adress1
//HTML code on a different page for last two buttons
profession1
profession2
//Javascript/JQuery code
$("#adress").click(function(){
//Some action here based on #address click event
$("#profession-1").click(function(){
//Some action if #profession was clicked after #address
});
$("#profession-2").click(function(){
//Some other action if #profession2 was clicked instead
of profession1
});
});
Someone had told me to use the following:
$('#adress').on('click', '#profession-1', function() {alert("x1")}).on('click', '#profession-2', function() {alert("x2")});
but its not working either. I feel like my program is not registering the click.
Your help is much appreciated!
The "root" element, in this case #address, isn't a proper element to attach the click event. You want to attach to some parent element and target a child element. Events in JavaScript bubble up and trickle back down to the element that initiated the event Event Propagation.
To remedy the issue:
$('#someParentEl').on(
'click',
'#profession-1',
function() {alert("x1")}
).on(
'click',
'#profession-2',
function() {alert("x2")}
);

The best way to accomplish something like this, is to have data attributes store whether or not something was clicked on... assuming this is a single page web app. Also make sure each id is unique, and referenced correctly for each click event.
address1
Then, when you click on that element, check if the data attribute is true or not on each click of the other elements.
$("#address").click(function(){
if($(this).attr("data-clicked") == "true") {
$(this).attr("data-clicked","false")
} else {
$(this).attr("data-clicked","true")
}
});
$("#profession-1").click(function(){
if($("#address").attr("data-clicked") == "true") {
//Some action
}
});
$("#profession-2").click(function(){
if($("#address").attr("data-clicked") == "true") {
//Some action
}
});
None of this was tested, but it should point you in the right direction.
I used the methods in this question:
change div class onclick on another div, and change back on body click
So here's my jQuery function:
jQuery('.checkbox_wrapper').on('click', function(e){
jQuery(this).parent()
.toggleClass('not_selected')
.toggleClass('selected');
});
However it doesn't seem to be working properly. It takes multiple clicks before the class changes.
See my jsfiddle:
http://jsfiddle.net/7A3vw/
I cut it down to the bare essentials thinking it might be conflicting javascript, but even with the single function it takes multiple clicks before the class actually changes. Because the production environment has 1 click toggle a hidden checkbox, multiple clicks is not reasonable.
Could someone help me figure out what's causing this issue?
The click function fires twice, once for the image, and once for the input, as both will bubble to the parent element, and firing twice reverts the classes again (proof).
Just target the image instead, as that is what you're really trying to click, not the parent :
jQuery('.deck_card img').on('click', function (e) {
jQuery(this).closest('div').parent().toggleClass('not_selected selected')
});
FIDDLE
i guest you need the checkbox checked together with the toggling of your div.
$(document).ready(function(e) {
$('.checkbox_wrapper').on('click', function(e){
var checked = $(this).find('input[type="checkbox"]').is(":checked");
if(checked){
jQuery(this).parent().addClass('selected').removeClass('not_selected');
}else{
jQuery(this).parent().addClass('not_selected').removeClass('selected');
}
});
});
Your code is triggering click event twice. So use .preventDefault()
This makes the default action of the event will not be triggered.
$('.checkbox_wrapper').on('click', function(e){
$(this).parent()
.toggleClass('not_selected')
.toggleClass('selected');
e.preventDefault(); // prevent the default action to be
}); // triggered for next time
Check this JSFiddle
try this
jQuery(document).on("click",'.checkbox_wrapper', function(e){
jQuery(this).parent()
.toggleClass('not_selected')
.toggleClass('selected');
});
Multiple Clicks are getting triggered because you are using class selector. You need to use not to exclude extra elements :
jQuery("div.checkbox_wrapper :not('div.checkboxdiv')").on('click', function(e){
jQuery(this).parent()
.toggleClass('not_selected selected')
});
Here is a FIDDLE.
Good morning,
I have a set of boxes on a page that are presented as a list, and within these boxes there might be some links that can be clicked. I want the links within the boxes to work as normal (i.e. bubble up and either perform the default action or then be handled by event handlers further up the DOM), but if the box is clicked anywhere else then it should be caught by a particular event handler attached to the "list" containing all the boxes.
Simple html representation
<div class="boxlist">
<div class="box" data-boxid="1">
Some text, and possibly a link and another link, and perhaps even a third link.
</div>
<div class="box" data-boxid="2">
Some more text, this time without a link.
</div>
</div>
The javascript that I thought should work.
$(function () {
$('.boxlist').on('click', '.box :not(a)', function (e) {
var boxid= $(this).closest('.box').data('boxid');
console.log('open: ' + boxid);
});
});
My expectation was that the above javascript should handle all clicks that did not originate from tags. However, for some reason when the box is clicked (either the box itself, or an tag, doesn't matter), it fires this event X times, where X is the total number of tags within the list of boxes.
So I have two questions:
1. What am I doing wrong with the :not() selector.
2. Is there a better way to handle this scenario?
Thank you for helping!
linkUsing jQuery :not selector actually is very slow ex:http://jsperf.com/not-vs-notdasdsad/4 and it's way better to just use event delegation. So in this case you want to keep track of every click on the .boxlist but check the node type to see if its an anchor or not. This is an example.
$(function () {
$('.boxlist').on('click', function(ev){
if(ev.target.tagName != "A"){
// handle box click code
console.log('box click');
return false;
}
// Otherwise allow event to bubble through.
});
});
and here is a jsfiddle example
http://jsfiddle.net/drXmA/
Also their are a few reasons your code doesn't work
.box :not(a)
should be
.box:not(a)
and the reason this also does not work is because .box is not an anchor tag it has children elements that are anchor tags it will never find an anchor tag named .box if their is one the callback would not execute. Changing the .box to an anchor tag will make it so the code doesn't execute because .box is an anchor and it is only running when .box:not(a)
I guess you want something like this:
$('.boxlist').on('click', '.box:not(a)', function (e) {
var boxid = $(this).closest('.box').data('boxid');
console.log('open: ' + boxid);
}).on('click', '.box a', function (e) {
e.preventDefault().stopPropagation();
});
DEMO FIDDLE
I think better to stop the default behavior and stop the event bubbling to its parent. .on() chain to the .box items excluding <a> from it and stop the default behavior and event bubble with e.preventDefault().stopPropagation();
Trying to figure out proper way to make a click event not fire on the icon of a disabled link. The problem is when you click the Icon, it triggers the click event. I need the selector to include child objects(I think) so that clicking them triggers the event whenever the link is enabled, but it needs to exclude the children when the parent is disabled.
Links get disabled attribute set dynamically AFTER page load. That's why I'm using .on
Demo here:(New link, forgot to set link to disabled)
http://jsfiddle.net/f5Ytj/9/
<div class="container">
<div class="hero-unit">
<h1>Bootstrap jsFiddle Skeleton</h1>
<p>Fork this fiddle to test your Bootstrap stuff.</p>
<p>
<a class="btn" disabled>
<i class="icon-file"></i>
Test
</a>
</p>
</div>
</diV>
$('.btn').on('click', ':not([disabled])', function () { alert("test"); });
Update:
I feel like I'm not using .on right, because it doesn't take the $('.btn') into account, only searching child events. So I find myself doing things like $('someParentElement').on or $('body').on, one being more difficult to maintain because it assumes the elements appear in a certain context(someone moves the link and now the javascript breaks) and the second method I think is inefficient.
Here is a second example that works properly in both enabled/disabled scenarios, but I feel like having to first select the parent element is really bad, because the event will break if someone rearranges the page layout:
http://jsfiddle.net/f5Ytj/32/
Don't use event delegation if you only want to listen for clicks on the .btn element itself:
$('.btn').on('click', function() {
if (!this.hasAttribute("disabled"))
alert("test");
});
If you'd use event delegation, the button would need to be the matching element:
$(someParent).on('click', '.btn:not([disabled])', function(e) {
alert('test!!');
});
Demo
Or use a true button, which can really be disabled:
<button class="btn" [disabled]><span class="file-icon" /> Test</button>
Demo, disabled.
Here, no click event will fire at all when disabled, because it's a proper form element instead of a simple anchor. Just use
$('.btn').on('click', function() {
if (!this.disabled) // check actually not needed
this.diabled = true;
var that = this;
// async action:
setTimeout(function() {
that.disabled = false;
}, 1000);
});
.on('click', ':not([disabled])'
^ This means that, since the icon is a child of the button ".btn", and it is not disabled, the function will execute.
Either disable the icon, also, or apply the event listener only to the <a> tag that is your button, or use e.stopPropagation();
I would suggest using e.stopPropagation();, this should prevent the icon from responding to the click.
That doesn't seem to work for me ^
Disabling the icon, however, does.
I would prefer to add the event using delegation here as you are trying to base the event based on the attributes of the element.
You can add a check condition to see if you want to run the code or not.
$('.container').on('click', '.btn', function() {
if( $(this).attr('disabled') !== 'disabled'){
alert('test!!');
}
});
Check Fiddle
You're not using the selector properly.
$('.btn').not('[disabled]').on('click', function () {
alert("test");
});
See it live here.
Edit:
$('.container').on('click', '.btn:not([disabled])', function () {
alert("test");
});
I think what you need is:
e.stopPropagation();
See: http://api.jquery.com/event.stopPropagation/
Basically something like the following should work
$('.icon-file').on('click', function(event){event.stopPropagation();});
You may want to add some logic to only stop bubbling the event when the button ist disabled.
Update:
not sure, but this selector should work:
$('.btn:disabled .icon-file')
In a page of a website I'm making, the press of a button imports the contents of a another php page and appends it onto the page. However, that other page contains JQuery, and the click event($( ".ExpandRoleButton").click) repeats itself on previous elements every time I import the content. So if I add 3 elements;
Element 1: Repeats the click event 3 times
Element 2: Repeats the click event 2 times
Element 3: Runs the click event once
$("#AjouterPiece").click(function()
{
$.blockUI({ message: '<img src="images/ChargementGeant.gif"/><br/><h1>Un moment svp.</h1>' });
$.post("wizardincl/piste.php", {newPiste: newPiste}, function(data)
{
$("#wizardPistes").append(data);
$.unblockUI();
$(".divNewPiste").fadeTo(300, 1);
$("#nbExemplaires").attr("max", newPiste);
newPiste++
$( ".ExpandRoleButton").click(function()
{
if ($(this).hasClass('RetractRoleButton'))
{
$(this).find('img').attr('src', 'images/ExpandPetitNoir.png');
var that = $(this);
$(this).parent().parent().parent().parent().next().slideUp(500, function() {
that.parent().parent().parent().parent().css('border-bottom', '1px solid #FF790B');
});
$(this).removeClass('RetractRoleButton');
}
else
{
$(this).parent().parent().parent().parent().css('border-bottom', 'none');
$(this).find('img').attr('src', 'images/ExpandPetitNoirRetour.png');
$(this).parent().parent().parent().parent().next().slideDown(500);
$(this).addClass('RetractRoleButton');
}
});
});
});
Currently, part of the JQuery website seems down and after some search, I can't find anything to solve the problem. Is there any way to keep the code from repeating itself like this?
This is because you are binding the event to multiple event handlers. The first time #AjouterPiece is clicked, all .ExpandRoleButton buttons get binded to an onclick handler.
The next time #AjouterPiece is clicked, it gets binded again.
To prevent this, you must unbind the click handlers using the following code before binding it
$( ".ExpandRoleButton").unbind('click')
You can pass in the event with .click(function(e) {...}) and then call e.stopImmediatePropagation() to fire only the current handler, but that only addresses the symptom, not the real problem.
Edit: make sure you are only binding the new instance of the button by adding a context to your selector, like $('.ExpandRoleButton', data). Since you are matching on a class, that selector will grab all the buttons on the page; the context allows you to select only the one inside your result.
A good practice ( solely to prevent issues like this from occurring, unintended multiple click handlers added ) is to..
$(".selector").off('click').on('click', function...
or
$(".selector").unbind('click')...
$(".selector").bind('click')...
