Android click event div element - javascript

I am having the following issue with click/touchstart event on Android (as far as I know only happening on Android),
1. the element triggers a modal window.
2. one of the buttons/links inside this modal gets triggered instantly without giving the user the option to make a choice.
It is of course required for the visitor/user to view the modal content before being redirected to a link to another page from one of those buttons.
I believe this is due to the 'touchstart' event bind to this div, which I am using since click events on divs for touch devices don't work.
I am using jQuery to make this work, and on iOS there doesn't seem to appear any issue.
$(document).on('click touchstart','.mydiv', function(e) {
e.preventDefault();
// open modal
});
Any suggestions please.

Try this:
$(.mydiv).on('touchstart', function(e) {
e.preventDefault();
// open modal
});
cheers

How to trigger an event in jQuery?

I'm working on a page that opens a modal window when the user clicks a certain radio button. I want to trigger whatever that event handler is via my own jQuery code. Right now, I'm attempting to mimic a user clicking on the radio button by:
$("#myRadioButton").trigger("click");
The code works somewhat. The state of the radio button does become selected. However, the modal window does not open.
What must I do to trigger the events and event handlers that make the modal window open?
(Also, is there a way in Chrome DevTools to see what events are attached to an element?)
This will make the click function work, with a id on the element. You will need to make some logic for the modal itself, inside the function.
Not sure there is a way to see the events in the developer console.
$( "#myRadioButton" ).click(function() {
//Whatever you wants to happen, when you click the button
alert( "You clicked on #myRadioButton" );
});

How to trigger my javascript pop up form with WordPress navigation link?

I've created a javascript pop up contact form, how do I trigger this after clicking a WordPress navigation item?
I have already tried the following code which works fine. However, after 1 second it loads the page which I've set the nav item to in WordPress.
document.getElementById('menu-item-177').addEventListener("click", function() {
document.querySelector('.bg-modal').style.display = "flex";
$('body').css('overflow','hidden')
});
I tried deleting the page, but obviously the nav link disappears. I also tried removing the menu item in the Menu settings of WordPress, same outcome.
I somehow need to block the page loading when the nav link is clicked. Is there a way round this?
Make sure that you are selecting the <a href=".. anchor element and listen for the click on that. I see that you have jQuery loaded in, so it might be good to just use that, or don't use it at all.
In your click event listener you listen for a click to happen. Whenever this click happens the function in the listener will be called. This function exposes some information about the event in the Event object. You'll see this in other pieces of code named e, evt, event or something else to refer to this Event object.
The Event object has a method called Event.preventDefault() which stops the browser from executing any kind of behavior that is linked to that element. Like navigating with an <a> tag. See why it is important to know what element you are clicking on? By adding that you can add your own behavior. See the example below.
$('#menu-item-177 > a').on('click', function(event) {
event.preventDefault(); // Prevents default navigation behavior.
$('.bg-modal').css('display', 'flex');
$('body').css('overflow', 'hidden');
});

Prevent double-click event on lower layer when double-click\hiding a higher layer

So I have a form where double-clicking a field brings up a custom modal window. The buttons for "Save" and "Cancel" on the modal window have "click" events that call hide() on the modal window layer. However, some of our users naturally double-click things. Double-clicking the save or cancel buttons fires the click event and hides the modal window but also fires the double-click event of the field that was under the modal window causing the modal window to display again. I know using a setTimeOut() and delaying the hide() of the modal window will resolve the issue but I prefer not to degrade the responsiveness of the UI if possible. Any suggestions?
Here is a fiddle to generally explain the problem.
https://jsfiddle.net/e51rc24j/4/
$(function() {
$(".field").on("dblclick", function(ev) {
$(".hoverlayer").show();
});
$(".hoverlayer").on("click", function(ev) {
var thisLayer = this;
$(thisLayer).hide();
/* PUTTING IN DELAY ON HIDE SOLVES PROBLEM BUT I PREFER TO NOT DELAY UI RESPONSIVENESS IF POSSIBLE
setTimeout(function(){
$(thisLayer).hide();
}, 300);*/
});
});
At first I thought the problem was propagation, so I added a stopPropagation to your event. But then I found out that it's not the double click that's propagating. The problem is something completely different, namely that the SECOND click (of the double click to close the black overlay) LANDS on the input field again, which triggers the double click event on the input box again.
So all you have to do, is move the SAVE and CANCEL buttons so they are not directly on top of the input field.
I have made a little change to your jsfiddle to illustrate:
https://jsfiddle.net/e51rc24j/6/
If you double click in the "PROBLEM", the modal black div will open again, because your second click lands INSIDE the <input> text field.
However, if you double click anywhere else in the black div ("Not a problem"), it will not open.

jQuery mobile automatic click/tab bug on next page in iOS7

I'm binding my tab events like this:
$('#submit').on("tap", function(){
$("body").pagecontainer("change", "#page-2");
});
My Problem is that the tab event fires automatically on the same position on the next page.
So when I got 2 buttons on the same positions on two different pages and I click/tab on the first button, the view slides to the next page and the event fires on the second button too.
This is only happening in iOS7. Any idea what i'm doing wrong?
(jQuery mobile version 1.4.2)
No idea if this will solve your problem or not, but you should probably be accepting an event parameter and preventing the default action if the click target is a button in a form or an anchor tag. You might also want to prevent the event from bubbling up by using stopPropagation. Depending on the underlying element you may actually be seeing the effect of the default action for that element or getting a full page refresh. That might have the appearance of the other action being invoked.
$('#submit').on("tap", function(e){
e.preventDefault();
e.stopPropagation(); // and also maybe prevent the event from bubbling up
$("body").pagecontainer("change", "#page-2");
});

jQuery click handlers not triggered inside a modal window

I have a very simple click handler that makes an AJAX GET request on click like so:
$('span.switch-option').click(function() {
$(this).parents('div.log-in-option').hide();
$(this).parents('div.log-in-option').siblings('div.log-in-option').fadeIn();
});
This works perfectly anywhere else on the website. However, when I try to click a <span> element with the class switch-option inside a modal window, the event does not fire. Entering the contents of the click-handler function in the console and running them does perform the desired behavior, however.
Why will the click handler not fire in this modal window? I am using the popular SimpleModal plugin http://www.ericmmartin.com/projects/simplemodal/ and jQuery 1.9.1.
A live example is here: http://ec2-107-22-8-70.compute-1.amazonaws.com/thread/19. If you click the 50,000 reps or any user's reputation then try to click the big blue link in the dialog, the click handler does not fire. This behavior happens with other click handlers in different modal windows as well.
When your script(main.js) is running the elements 'li.log-in, a.log-in' does not exists in the dom, they are loaded dynamically when the popup is created thus jQuery is not able to bind the event handlers
Try event propagation
$(document).on('click', 'li.log-in, a.log-in', function() {
$.get('/login/', function(data) {
//make a modal window with the html
$.modal(data);
});
return false;
});
