How to continue event propagation after cancelling?

This is untested but might serve as a workaround for you

$('a.my-link').click(function(e) {
e.preventDefault(); e.stopPropogation();
MyApp.confirm("Are you sure you want to navigate away?")
.done(function() {
//continue propogation of e
$(this).unbind('click').click()
})
})

Below are the bits from the code that actually worked in Chrome 13, to my surprise.

function handler (evt ) {
var t = evt.target;
...
setTimeout( function() {
t.dispatchEvent( evt )
}, 1000);
return false;
}

This is not very cross-browser, and maybe will be fixed in future, because it feels like security risk, imho.

And i don't know what happens, if you cancel event propagation.

I solved problem by this way on one of my projects. This example works with some basic event handling like clicks etc. Handler for confirmation must be first handler bound.

    // This example assumes clickFunction is first event handled.
//
// you have to preserve called function handler to ignore it
// when you continue calling.
//
// store it in object to preserve function reference
var ignoredHandler = {
fn: false
};


// function which will continues processing
var go = function(e, el){
// process href
var href = $(el).attr('href');
if (href) {
window.location = href;
}


// process events
var events = $(el).data('events');


for (prop in events) {
if (events.hasOwnProperty(prop)) {
var event = events[prop];
$.each(event, function(idx, handler){
// do not run for clickFunction
if (ignoredHandler.fn != handler.handler) {
handler.handler.call(el, e);
}
});
}
}
}


// click handler
var clickFunction = function(e){
e.preventDefault();
e.stopImmediatePropagation();
MyApp.confirm("Are you sure you want to navigate away?")
.done(go.apply(this, e));
};


// preserve ignored handler
ignoredHandler.fn = clickFunction;
$('.confirmable').click(clickFunction);


// a little bit longer but it works :)

If I am understanding the problem correctly, I think you can just update the event to be the original event in that closure you have there. So just set e = e.originalEvent in the .done function.

https://jsfiddle.net/oyetxu54/

MyApp.confirm("confirmation?")
.done(function(){ e = e.originalEvent;})

here is a fiddle with a different example (keep the console open so you can see the messages): this worked for me in chrome and firefox

I solved this by:

1. placing a event listener on a parent element
2. removing the class from the link ONLY when the user confirms
3. reclicking the link after I have removed the class.

function async() {
var dfd = $.Deferred();
  

// simulate async
setTimeout(function () {
if (confirm('Stackoverflow FTW')) {
dfd.resolve();
} else {
dfd.reject();
}
}, 0);
  

return dfd.promise();
};


$('.container').on('click', '.another-page', function (e) {
e.stopPropagation();
e.preventDefault();
async().done(function () {
$(e.currentTarget).removeClass('another-page').click();
});
});


$('body').on('click', function (e) {
alert('navigating somewhere else woot!')
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


<div class="container">
<a href="#" class="another-page">Somewhere else</a>
</div>

The reason I added the event listener to the parent and not the link itself is because the jQuery's on event will bind to the element until told otherwise. So even though the element does not have the class another-page it still has the event listener attached thus you have to take advantage of event delegation to solve this problem.

GOTCHAS this is very state based. i.e. if you need to ask the user EVERYTIME they click on a link you'll have to add a 2nd listener to readd the another-page class back on to the link. i.e.:

$('body').on('click', function (e) {
$(e.currentTarget).addClass('another-page');
});

side note you could also remove the event listener on container if the user accepts, if you do this make sure you use namespace events because there might be other listeners on container you might inadvertently remove. see https://api.jquery.com/event.namespace/ for more details.

We have a similar requirement in our project and this works for me. Tested in chrome and IE11.

$('a.my-link').click(function(e) {
e.preventDefault();
if (do_something === true) {
e.stopPropogation();
MyApp.confirm("Are you sure you want to navigate away?")
.done(function() {
do_something = false;
// this allows user to navigate
$(e.target).click();
})
}


})

I edited your code. New features that I added:

1. Added namespace to event;
2. After click on element event will be removed by namespace;
3. Finally, after finish needed actions in "MyApp" section continue propagation by triggering others element "click" events.

Code:

$('a.my-link').on("click.myEvent", function(e) {
var $that = $(this);
$that.off("click.myEvent");
e.preventDefault();
e.stopImmediatePropagation();
MyApp.confirm("Are you sure you want to navigate away?")
.done(function() {
//continue propogation of e
$that.trigger("click");
});
});

It could be risky but seems to work at the time of writing at least, we're using it in production.

This is ES6 and React, I have tested and found it working for the below browsers. One bonus is if there is an exception (had a couple during the way making this), it goes to the link like a normal <a> link, but it won't be SPA then ofc.

Desktop:

• Chrome v.76.0.3809.132
• Safari v.12.1.2
• Firefox Quantum v.69.0.1
• Edge 18
• Edge 17
• IE11

Mobile/Tablet:

• Android v.8 Samsung Internet
• Android v.8 Chrome
• Android v.9 Chrome
• iOs11.4 Safari
• iOs12.1 Safari

import 'mdn-polyfills/MouseEvent'; // for IE11
import React, { Component } from 'react';
import { Link } from 'react-router-dom';


class ProductListLink extends Component {
constructor(props) {
super(props);
this.realClick = true;


this.onProductClick = this.onProductClick.bind(this);
}


onProductClick = (e) => {
const { target, nativeEvent } = e;
const clonedNativeEvent = new MouseEvent('click', nativeEvent);


if (!this.realClick) {
this.realClick = true;
return;
}


e.preventDefault();
e.stopPropagation();


// @todo what you want before the link is acted on here


this.realClick = false;
target.dispatchEvent(clonedNativeEvent);
};


render() {
<Link
onClick={(e => this.onProductClick(e))}
>
Lorem
</Link>
}
}
