I have a slider that scrolls when user uses scroll wheel, but on mobile phone it doesn't work. How i should solve this? I used jQuery scroll() but it is not working. Help please.
The slider is pretty much simple, and totaly fine on computer, but it is not working on my phone
What should i use? What method?
$(document).ready(function() {
var curPage = 1;
var numOfPages = $(".skw-page").length;
var animTime = 1000;
var scrolling = false;
var pgPrefix = ".skw-page-";
function pagination() {
scrolling = true;
$(pgPrefix + curPage).removeClass("inactive").addClass("active");
$(pgPrefix + (curPage - 1)).addClass("inactive");
$(pgPrefix + (curPage + 1)).removeClass("active");
setTimeout(function() {
scrolling = false;
}, animTime);
};
function navigateUp() {
if (curPage === 1) return;
curPage--;
pagination();
};
function navigateDown() {
if (curPage === numOfPages) return;
curPage++;
pagination();
};
$(document).on("mousewheel DOMMouseScroll", function(e) {
if (scrolling) return;
if (e.originalEvent.wheelDelta > 0 || e.originalEvent.detail < 0) {
navigateUp();
} else {
navigateDown();
}
});
$(document).on("keydown", function(e) {
if (scrolling) return;
if (e.which === 38) {
navigateUp();
} else if (e.which === 40) {
navigateDown();
}
});
});

I have created a script to show tabs in Divi when you click on a menu entry. Divi does not use ids and hrefs for this, so I had to use a script.
The problem that I am facing is that this script that I made does not work with Divi's mobile menu.
I checked if menuSelector changed properly and if changeMenuSelector got executed as expected.
Furthermore, $('#'+menuSelector+' a[href*="howtos"]').length returns 1 in console and if I run $('#'+menuSelector+' a[href*="howtos"]')[0] in console I obtain the expected DOM element whehter I have the browser window sized for mobile or for desktop devices.
I also tried using setTimeout in case the issue was that it needed some time to accomplish an earlier action without any luck.
Therefore, is there anyone that could tell me why this does not work when the website is running in mobile mode?
I solved the issue by refactoring the code like this:
jQuery(function ($) {
console.log('test');
var tab = null;
var menuSelector = null;
var guard = false;
function changeMenuSelector() {
if ($(document).width() > 967) {
menuSelector = 'top-menu-nav';
guard = false;
initEventListeners(guard);
} else {
menuSelector = 'mobile_menu';
guard = true;
initEventListeners(guard);
}
}
function initEventListeners(guard) {
var localGuard = null;
if (localGuard != guard) {
var hrefs = ['howtos', 'projects', 'reviews', 'elearning', 'others'];
hrefs.forEach(
function (element, index, array) {
$('#' + menuSelector + ' a[href*="' + element + '"]').off();
console.log(element);
$('#' + menuSelector + ' a[href*="' + element + '"]').on('click', function (e) {
e.preventDefault();
console.log('pluto');
window.localStorage.setItem('tab', 'et_pb_tab_' + index);
if (window.location.pathname.indexOf('blog-posts') === -1) {
window.location.href = 'http://www.davidepugliese.com/blog-posts/';
} else {
tab = localStorage.getItem('tab');
$("li." + tab + ">a")[0].click();
$("html, body").animate({ scrollTop: $('.et_pb_module.et_pb_tabs.et_pb_tabs_0').offset().top },
1000);
window.localStorage.removeItem('tab');
}
});
});
localGuard = guard;
}
}
changeMenuSelector();
initEventListeners();
$(window).resize(function () {
changeMenuSelector();
});
if (!!localStorage.getItem('tab')) {
tab = localStorage.getItem('tab');
console.log(tab);
setTimeout(function(){$("li."+tab+">a")[0].click();}, 1)
$("html, body").animate({ scrollTop: $('.et_pb_module.et_pb_tabs.et_pb_tabs_0').offset().top },
1000);
localStorage.removeItem('tab');
}
});
I have this long list with overflow: auto to scroll through it, i set it up for keyboard navigation, the problem is that when using the keyboard it doesn't scroll correctly!
check this jsFiddle
$('ul').keydown(function (e) {
if (e.keyCode == 38) { // up
var selected = $(".selected");
$listItems.removeClass("selected");
if (selected.prev().length == 0) {
selected.siblings().last().addClass("selected");
} else {
selected.prev().addClass("selected");
}
}
if (e.keyCode == 40) { // down
var selected = $(".selected");
$listItems.removeClass("selected");
if (selected.next().length == 0) {
selected.siblings().first().addClass("selected");
} else {
selected.next().addClass("selected");
}
}
})
});
$listItems.click(function () {
if ($(this).is('.selected')) {
return true;
} else {
$('li').removeClass('selected');
$(this).addClass('selected');
}
the behavior i'm looking for is the same behavior of the element when scrolling through a long list of elements using the keyboard this plugin SelectBoxIt show's what i'm looking for.
you can use this code instead, i used animate function to navigate inside the div if the list exceed the width of the ul tag :
http://jsfiddle.net/goldendousa/p6243/13/
$('ul').focus(function() {
if ($('ul li').is('.selected')) {
$('ul li').first().removeClass('selected');
} else {
$('ul li').first().addClass('selected');
}
});
$('ul').keydown(function(e) {
if (e.keyCode == 38) { // up
e.preventDefault();
var selected = $(".selected");
$("ul li").removeClass("selected");
if (selected.prev().length == 0) {
selected.siblings().last().addClass("selected");
var selectedTopOffset = selected.siblings().last().offset().top;
$('div').animate({
scrollTop: selectedTopOffset
}, 200);
} else {
selected.prev().addClass("selected");
var selectedTopOffset = $("div").scrollTop() + selected.position().top - $("div").height()/2 + selected.height()/2;
$('div').animate({
scrollTop: selectedTopOffset
}, 200);
}
}
if (e.keyCode == 40) { // down
e.preventDefault();
var selected = $(".selected");
$("ul li").removeClass("selected");
if (selected.next().length == 0) {
selected.siblings().first().addClass("selected");
if (selected.siblings().first().offset().top < 0) {
$('div').animate({
scrollTop: selected.siblings().first().offset().top
}, 200);
}
} else {
selected.next().addClass("selected");
var selectedTopOffset = $("div").scrollTop() + selected.position().top - $("div").height()/2 + selected.height()/2;
$('div').animate({
scrollTop: selectedTopOffset
}, 200);
}
}
});
$('li').click(function() {
if ($(this).is('.selected')) {
return true;
} else {
$('li').removeClass('selected');
$(this).addClass('selected');
}
});
how is it possible catch the "mousewheel" event on a body with an hidden overflow?
I have already tried this but it doesn't work on my case.
You can use jQuery mousewheel plugin.
EDIT: Here is the code from my plugin:
var self = this;
var scroll_object;
if (!navigator.userAgent.toLowerCase().match(/(webkit)[ \/]([\w.]+)/) &&
self[0].tagName.toLowerCase() == 'body') {
scroll_object = $('html');
} else {
scroll_object = self;
}
...
self = $.extend(self, {
scroll: function(amount) {
var pos;
amount = Math.round(amount);
if (scroll_object.prop) {
if (amount > scroll_object.prop('scrollTop') && amount > 0) {
scroll_object.prop('scrollTop', 0);
}
pos = scroll_object.prop('scrollTop');
scroll_object.scrollTop(pos + amount);
return self;
} else {
if (amount > scroll_object.attr('scrollTop') && amount > 0) {
scroll_object.attr('scrollTop', 0);
}
pos = scroll_object.attr('scrollTop');
scroll_object.scrollTop(pos + amount);
return self;
}
},
...
self.mousewheel(function(event, delta) {
if (delta > 0) {
self.scroll(-40);
} else {
self.scroll(40);
}
return false;
}, true);
So using a script for 360 image rotation, i've set up a tags to act as hot spots and lead to different pages within a jquery mobile document. Everything works a desktop, but when i test the page on an ipad, none of the links do anywhere. Heres the script for the rotation.
<script>
jQuery(document).ready(function ($) {
var $product = $('#product'),
$imgs = $product.find(".child"),
imageTotal = $imgs.length - 1,
clicked = false,
widthStep = 4,
currPos,
currImg = 0,
lastImg = 0;
$imgs.bind('mousedown', function (e) {
e.preventDefault(); // prevent dragging images
})
.filter(':gt(0)').addClass('notseen');
$product.bind('mousedown touchstart', function (e) {
if (e.type == "touchstart") {
currPos = window.event.touches[0].pageX;
} else {
currPos = e.pageX;
}
clicked = true;
return false;
});
$(document)
.bind('mouseup touchend', function () {
clicked = false;
})
.bind('mousemove touchmove', function (e) {
if (clicked) {
var pageX;
if (e.type == "touchmove") {
pageX = window.event.targetTouches[0].pageX;
} else {
pageX = e.pageX;
}
widthStep = 4;
if (Math.abs(currPos - pageX) >= widthStep) {
if (currPos - pageX >= widthStep) {
currImg++;
if (currImg > imageTotal) {
currImg = 0;
}
} else {
currImg--;
if (currImg < 1) {
currImg = imageTotal;
}
}
currPos = pageX;
$imgs.eq(lastImg).addClass('notseen');
$imgs.eq(currImg).removeClass('notseen');
lastImg = currImg;
// $obj.html('<img src="' + aImages[options.currImg] + '" />');
}
}
});
});
</script>
I'm know its the script because when i remove it, the links work. Any ideas?
jQuery(document).ready() is not supported in jQM.

What is the best way to capture a left AND right mouse click in javascript? I'm not using jQuery (it's next on my to-learn list), just javascript for now. Basically, I want to do something like
onClick()=javascript:rightClickFunction() // do right click function
onContextMenu()=javascript:leftClickFunction() /
onBoth() ???
The only thing I could find on stackoverflow was:
How to distinguish between left and right mouse click with jQuery
How should I capture the double-button click? Can i check if the opposite button is also clicked during the R and L button routines?
You could track which mouse buttons are down with some boolean variables like this:
var leftButtonDown = false;
var rightButtonDown = false;
$(document).mousedown(function() {
if(e.which == 1) {
leftButtonDown = true;
} else if (e.which == 3) {
rightButtonDown = true;
}
});
$(document).mouseup(function() {
if(e.which == 1) {
leftButtonDown = false;
} else if (e.which == 3) {
rightButtonDown = false;
}
});
$(document).click(function() {
if(leftButtonDown && rightButtonDown) {
// left and right buttons are clicked at the same time
}
});
If both booleans are true, the right and left mouse buttons are both being clicked.
Pure Javascript solution based on the answer by Elliot:
var leftButtonDown = false;
var rightButtonDown = false;
document.addEventListener("mousedown", function () {
if (e.which == 1) {
leftButtonDown = true;
} else if (e.which == 3) {
rightButtonDown = true;
}
});
document.addEventListener("mouseup", function () {
if (e.which == 1) {
leftButtonDown = false;
} else if (e.which == 3) {
rightButtonDown = false;
}
});
document.addEventListener("click", function () {
if (leftButtonDown && rightButtonDown) {
// Click with both LMB and RMB.
}
});
For anyone still interested in a recent answer, as event.which is deprecated you can use the following code with ES6 syntax.
let leftButtonDown = false;
let rightButtonDown = false;
document.addEventListener("mousedown", (e) => {
// left click
if (e.button === 0) {
leftButtonDown = true;
}
// right click
if (e.button === 2) {
rightButtonDown = true;
}
if (leftButtonDown && rightButtonDown) {
// insert code here
}
});
document.addEventListener("mouseup", (e) => {
if (e.button === 0) {
leftButtonDown = false;
}
if (e.button === 2) {
rightButtonDown = false;
}
});
If you want to prevent the context menu from popping up you can try a variation of this:
let leftButtonDown = false;
let rightButtonDown = false;
document.addEventListener("mousedown", (e) => {
// left click
if (e.button === 0) {
leftButtonDown = true;
}
// right click
if (e.button === 2) {
rightButtonDown = true;
}
if (leftButtonDown && rightButtonDown) {
// insert code here
}
});
document.addEventListener("mouseup", (e) => {
if (e.button === 0) {
leftButtonDown = false;
}
});
document.addEventListener("contextmenu", (e) => {
if (leftButtonDown && rightButtonDown) {
e.preventDefault();
}
rightButtonDown = false;
});
Modern browsers mouse buttons mapping:
left click = 0
middle click = 1
right click = 2
IE8 and earlier mouse buttons mapping:
left click = 1
middle click = 4
right click = 2
