I have a masonry layout with each cell is infact a hyperlink requiring a hover state to be shown.
On ipad (as predicted) the hover states did not display. The client has requested that the links should now need two clicks: once to display the hover state, and a second click to engage the hyperlink - So I used this bit of javascript:
$(document).ready(function() {
$('.my_button').bind('touchstart touchend', function(e) {
e.preventDefault();
$(this).toggleClass('hover_effect');
});
});
The problem now is that on ipad the hover states now display (which is great), but the second click is being ignored and does nothing.

With
e.preventDefault();
you prevent the default behaviour so the click/touch will never be able to follow the link. Try like so
$(document).ready(function() {
$('.my_button').bind('touchstart touchend', function(e) {
if($(this).hasClass('hover_effect') {
return; // skip rest of code, so default will happen
// which is following the link
}
e.preventDefault();
$(this).addClass('hover_effect'); // no reason to toggleClass
// cause the seccond click/touch should always go to destination
});
});
Now probably you want it though that if click/touch on a different $('.my_button') you need to remove the hover_effect to all the other my_button(s) so add
$('.my_button').not(this).removeClass('hover_effect');
like so
$(document).ready(function() {
$('.my_button').bind('touchstart touchend', function(e) {
$('.my_button').not(this).removeClass('hover_effect');
if($(this).hasClass('hover_effect') {
return; // skip rest of code
}
e.preventDefault();
$(this).addClass('hover_effect'); // no reason to toggleClass
// cause the seccond click/touch should always go to destination
});
});
I haven't tried the code, but it should work. Let me know if it doesn't.
A little bit more research, and I have come up with this solution which works:
jQuery(document).ready(function(){
$('.middle').bind('touchstart touchend', function(e) {
//This will return true after the first click
//and preventDefault won't be called.
if(!$(this).hasClass('nav_returnlink'))
e.preventDefault();
$(this).addClass('nav_returnlink');
});
});

JS Fiddle Example
I'm opeing the dropdown boxes using the 'FOO', 'BOO' items in the navigation bar and I'm closing them when a click event occurs outside using the following code which is working fine.
$(document).on('click', '.dd-box', function() {
// Comment out the return statement below and the links will start working.
return false
});
The problem that I'm experiencing is that this is also stopping the links within the dropdown boxes from being visted.
The reason I need this code is because I don't want the dropdown boxes to close when click events happen within them.
I'm trying to avoid using hacks like window.open to force the link from being visited, any ideas?
you should put stopPropagation
$(document).ready(function() {
$("a").click(function(e) {
e.stopPropagation();
});
...
see JSFiddle
$(function(){
$(".OpenTopMenu").click(function (e) {
$("#top_menu").slideToggle("fast");
e.stopPropagation();
});
$(document).click(function() {
$("#top_menu").hide();
});
$(document).on("touchend", function (event) {
if (!$(event.target).closest("#top_menu").length) {
$("#top_menu").hide();
}
});
});
Hi all, i ran into a strange problem with toggle and hide.
As you can see in my code. If i touch the menu button (.OpenTopMenu) the menu (#top_menu) toggle.
And here its the problem. If #top_menu is visible so when i touch on .OpenTopMenu, #top_menu will hide then toggle to visible again. So i can't really hide #top_menu on touching the menu button (.OpenTopMenu).
Can someone help me with this?
Thanks
Your touchend and click are basically doing the same thing. For mobile uses it's always good to know that a "click" can actually be seen as two events that rapidly follow each other, namely the "mousedown" and "mouseup" event, the last one triggering the "click". On mobile devices, the "click" is triggered at the same time as your "touchend". Now there's also an event called "touchstart" which is triggered when a user put's his / her finger on the glass.
You are right now wondering what all this has to do with your question. Well, it has to do with your document click..
Personally I would solve your problem in the following way;
var userClick = function(){
//you will need something that determines whether your user is
//using a mobile device or not.
return (Browser.isMobile)? "touchend" : "click";
};
var menu = {
isOnMenu:false,
isOnMenu_reset:null,
attachEvents:function(){
$('#top_menu').on('mouseenter',function(){
menu.isOnMenu = true;
}).on('mouseleave',function(){
menu.isOnMenu = false;
}).on('touchstart',function(){
clearTimeout(menu.isOnMenu_reset);
menu.isOnMenu = true;
}).on('touchend',function(){
menu.isOnMenu_reset = setTimeout(function(){
menu.isOnMenu = false;
},30);
});
$('.OpenTopMenu').on(userClick(),function(){
$("#top_menu").slideToggle("fast");
});
$(document).on(userClick(),function(){
if(!menu.isOnMenu){
$('#top_menu').slideToggle("fast");
}
});
},
init:function(){
menu.attachEvents();
}
};
$(function(){
menu.init();
});
Try to change your $(document).click() by somthing like $(".OpenTopMenu").blur(). This might not work with old browsers.
I only wanted click and touched for testing purpose.
But it only have to work with touchend. This is the working code that i finally use. Thanks.
$(document).ready(function(){
$(".OpenTopMenu").click(function(){
$("#top_menu").slideToggle("fast");
});
});
$(document).on("touchend", function(event){
var $trigger = $(".OpenTopMenu");
if($trigger !== event.target && !$trigger.has(event.target).length){
$("#top_menu").slideUp("fast");
}
});
I tried earlier with
!event.target.hasClass('OpenTopMenu') instead of $trigger !== event.target
in the if condition but it doesn't work. Can someone tell me why the upper code work and this one not?
I am trying to make the below JSFiddle work for tablet/mobile devices (e.g. 'on touch' as well as 'click').
https://jsfiddle.net/lkw274/7zt1zL0g/87/
<div class="user-navigation">
<a class="mobile-menu-new" href=""><span></span>Menu</a>
</div>
$(document).ready(function() {
$(".user-navigation a.mobile-menu-new").click(function (e) {
e.preventDefault();
$(".user-navigation a.mobile-menu-new").toggleClass("current");
});
});
.current { background: #F00;}
Expected behaviour:
On clicking 'Menu', either by touch or with clicked with mouse, the background is highlighted red until it is clicked again when the class should be removed, removing the red background and returning it to its original state.
Current behaviour:
On clicking 'Menu', by touch on mobile/tablet device, the background is highlighted red however the class is not removed when 'menu' is clicked for the second time.
Could anyone help to understand how this code needs to be modified for tablet/mobile devices?
I have tried the solution in the below StackOverflow link however this did not function on click once implemented.
document-click-function-for-touch-device
Thanks in advance.
Looks like event delegation is the way to do this since, when you modify the target element, bind seems to fail.
Try the following (works on my iPhone/Chrome).
$(document).ready(function() {
$(".user-navigation").delegate("a.mobile-menu-new", "click", function (e) {
e.preventDefault();
$(this).toggleClass("current");
});
});
Please note I have used .delegate since you seem to be using jQuery 1.6 (as per your fiddle) as otherwise, with jQuery 1.7+, you could use .on like below.
$(document).ready(function() {
$(".user-navigation").on("click", "a.mobile-menu-new", function (e) {
e.preventDefault();
$(this).toggleClass("current");
});
});
add the cursor:pointer to the property of your class and it should work find in mobile
.user-navigation{
cursor:pointer
}
$(selector).bind("click touchstart", function(){
.......
});
Well, in modern jQuery versions, I suppose something like this:
$(document).on('click','selector', function(e){
e.preventDefault();
your code here
});
...would do the trick for mobile devices...
This chunk of code
$(document).click(function(e) {
$('#mymodal').modal('show');
});
captures a click anywhere on the page.
Unless that click is on a link, in which case the browser seems to follow the link rather than popping up the modal (at least, this is the behavior in Chrome).
How can I capture that the click, even if it's on a link?
One idea: overlaying the page with a fixed-position div that covers everything and captures the click. But maybe there is a more elegant way?
Add return false;:
$(document).on('click', function(e) {
$('#mymodal').modal('show');
return false;
});
JSFIDDLE
For more information read this thread.
You can do this :
$(document).on('click', function(e) {
$('#mymodal').modal('show');
return false; // avoids the propagation and the link default behavior
});
Currenlty when a page is posting back or something else is going on I display a big grey div over the top of the whole page so that the user can't click the same button multiple times. This works fine 99% of the time, the other 1% is on certain mobile devices where the user can scroll/zoom away from the div.
Instead of trying to perfect the CSS so that it works correctly (this will be an on going battle with new devices) I've decided to just stop the user from being able to click anything. Something like $('a').click(function(e){e.preventDefault();}); would stop people from clicking anchor tags and navigating to the link but it wouldn't stop an onclick event in the link from firing.
I want to try to avoid changing the page too radically (like removing every onclick attribute) since the page will eventually have to be changed back to its original state. What I would like to do is intercept clicks before the onclick event is executed but I don't think that this is possible. What I do instead is hide the clicked element on mouse down and show it on mouseup of the document, this stops the click event firing but doesn't look very nice. Can anyone think of a better solution? If not then will this work on every device/browser?
var catchClickHandler = function(){
var $this = $(this);
$this.attr('data-orig-display', $this.css('display'));
$this.css({display:'none'});
};
var resetClickedElems = function(){
$('[data-orig-display]').each(function(){
$(this).css({display:$(this).attr('data-orig-display')}).removeAttr('data-orig-display');
});
};
$('#btn').click(function(){
$('a,input').on('mousedown',catchClickHandler);
$(document).on('mouseup', resetClickedElems);
setTimeout(function(){
$('a,input').off('mousedown',catchClickHandler);
$(document).off('mouseup', resetClickedElems);
}, 5000);
});
JSFiddle: http://jsfiddle.net/d4wzK/2/
You could use the jQuery BlockUI Plugin
http://www.malsup.com/jquery/block/
You can do something like this to prevent all actions of the anchor tags:
jQuery('#btn').click(function(){
jQuery('a').each(function() {
jQuery(this).attr('stopClick', jQuery(this).attr('onclick'))
.removeAttr('onclick')
.click(function(e) {
e.preventDefault();
});
});
});
That renames the onclick to stopclick if you need to revert later and also stops the default behavior of following the href.
document.addListener('click',function(e){e.preventDefault()})
Modified-
Its your duty to remove the click event from the document after you are done accomplishing with your task.
Eg -
function prevent(e){
e.preventDefault()
}
//add
document.addListener('click',prevent)
//remove
document.removeListener('click',prevent)
