In the code below, the right-click is not getting trapped. left-click works fine. This code was given in the dojo documentation. Can someone tell me why isRight is not working? Essentially, when I right-click the element, I just get the browser's right-click menu, no console message is generated.
https://dojotoolkit.org/reference-guide/1.10/dojo/mouse.html
on(myNode,'click',function(e) {
if (mouse.isLeft(e)){
console.log("left click", e);
} else if (mouse.isRight(e)){
console.log("right click",e);
}
});
The browser right click context menu consumes the click event. It will work if you use 'mousedown' instead of 'click'. There are also many questions about right click detection in javascript that you can look into for alternate methods. For example: Failing to identify right click event in Mozilla Firefox.
The dojo/mouse module is mostly a utility wrapper over the usual event handling, so the information in these questions still applies.
You cannot detect mouse.isRight when using event click. Instead you could use mousedown as in the following example:
https://jsfiddle.net/xgekrp5e/
require(["dojo/mouse", "dojo/on"], function(mouse, on) {
on(document, "mousedown", function(evt) {
if (mouse.isLeft(event)) {
// handle mouse left click
alert('MOUSE LEFT');
} else if (mouse.isRight(event)) {
// handle mouse right click
alert('MOUSE RIGHT');
}
});
});
I need to capture the event that occurs when a user clicks a link on my chat application. I am using IE11.
Is there a way to capture the user clicking the link, when such a link could be dynamically added to the chat box (i.e. user sends "www.google.com" message) at any given time?
I have been using onbeforeunload by the way and while this detects the browser close event it will not detect the link click event, I am not sure why, so I was thinking that a jquery solution that checks the links on the page for an onclick could solve my problem...
Thanks,

Yes, you can use event delegation like:
$("#chatWindow).on('click', 'a', function () {
//do something
});
You could do it with a function like this:
$('a').on('click', function(){
//track clicked link here
return true; //to allow following the link this is the default behavior no need to add
return false; //prevent default behavior
});
Im using hammer.js for gestures in a html5 app, also on phonegap.
I want to prevent normal clicks of links to go to the link, but I want t tap event to let the link pass. Im trying this sofar, but it prevents both events, I guess the click events comes first
$(document).hammer().on("tap click", "a", function(e){
if e.type == "click"
return false
}
I want to do this because I have a hold event, and after the hold is done over a link, the link is fired. I dont want this to happen..
listen for
$(document).on('touchend',function(e){
/*
you code here
*/
e.preventDefault();
e.stopPropagation()
});
In Chrome the right-click dialog seems to swallow all mouse events. This means that you get mouse-down events without corresponding mouse-up events.
This includes every right-click, and any left-click where the right button is pressed before the left button is released (in which case you get two mouse-downs but no mouse-ups).
You can see the problem in action here (you may wish to mute your speakers) if you're curious.
I was just wondering if anyone knew of any workarounds for this? Using window.onmousedown instead of document.onmousedown doesn't fix the problem unfortunately.
You'll want to add a handler for the contextmenu event that cancels the opening of that menu.
See MDN for some details.
window.oncontextmenu = function(event) {
event.preventDefault();
event.stopPropagation();
return false;
};
It appears that the Blur event stops the click event handler from working? I have a combo box where the options only appear when the text field has focus. Choosing an option link should cause an event to occur.
I have a fiddle example here: http://jsfiddle.net/uXq5p/6/
To reproduce:
Select the text box
Links appear
Click a link
The blur even occurs and the links disappear
Nothing else happens.
Expected behavior:
On step 5, after blur occurs, the click even should also then fire. How do I make that happen?
UPDATE:
After playing with this for a while, it seems that someone has gone to great lengths to prevent an already-occurred click event from being handled if a blur event makes the clicked element Un-clickable.
For example:
$('#ShippingGroupListWrapper').css('left','-20px');
works just fine, but
$('#ShippingGroupListWrapper').css('left','-2000px');
prevents the click event.
This appears to be a bug in Firefox, since making an element un-clickable should prevent future clicks, but not cancel ones that have already occurred when it could be clicked.
Other things that prevent the click event from processing:
$('#ShippingGroupListWrapper').css('z-index','-20');
$('#ShippingGroupListWrapper').css('display','none');
$('#ShippingGroupListWrapper').css('visibility','hidden');
$('#ShippingGroupListWrapper').css('opacity','.5');
I've found a few other questions on this site that are having similar problems. There seem to be two solutions floating around:
Use a delay. This is bad because it creates a race condition between the hiding and the click event handler. Its also sloppy.
Use the mousedown event. But this isn't a great solution either since click is the correct event for a link. The behavior of mousedown is counter-intuitive from a UX perspective, particularly since you can't cancel the click by moving the mouse off the element before releasing the button.
I can think of a few more.
3.Use mouseover and mouseout on the link to enable/disable the blur event for the field. This doesn't work with keyboard tabing since the mouse is not involved.
4.The best solution would be something like:
$('#ShippingGroup').blur(function()
{
if($(document.activeElement) == $('.ShippingGroupLinkList'))
return; // The element that now has focus is a link, do nothing
$('#ShippingGroupListWrapper').css('display','none'); // hide it.
}
Unfortunately, $(document.activeElement) seems to always return the body element, not the one that was clicked. But maybe if there was a reliable way to know either 1. which element now has focus or two, which element caused the blur (not which element is blurring) from within the blur handler. Also, is there any other event (besides mousedown) that fires before blur?
click event triggers after the blur so the link gets hidden. Instead of click use mousedown it will work.
$('.ShippingGroupLinkList').live("mousedown", function(e) {
alert('You wont see me if your cursor was in the text box');
});
Other alternative is to have some delay before you hide the links on blur event. Its upto you which approach to go for.
Demo
You could try the mousedown event instead of click.
$('.ShippingGroupLinkList').live("mousedown", function(e) {
alert('You wont see me if your cursor was in the text box');
});
This is clearly not the best solution as a mousedown event is not achieved the same way for the user than a click event. Unfortunately, the blur event will cancel out mouseup events as well.
Performing an action that should happen on a click on a mousedown is bad UX. Instead, what's a click effectively made up of? A mousedown and a mouseup.
Therefore, stop the propagation of the mousedown event in the mousedown handler, and perform the action in the mouseup handler.
An example in ReactJS:
<a onMouseDown={e => e.preventDefault()}
onMouseUp={() => alert("CLICK")}>
Click me!
</a>
4.The best solution would be something like:
$('#ShippingGroup').blur(function()
{
if($(document.activeElement) == $('.ShippingGroupLinkList'))
return; // The element that now has focus is a link, do nothing
$('#ShippingGroupListWrapper').css('display','none'); // hide it.
}
Unfortunately, $(document.activeElement) seems to always return the
body element, not the one that was clicked. But maybe if there was a
reliable way to know either 1. which element now has focus or two,
which element caused the blur (not which element is blurring) from
within the blur handler.
What you may be looking for is e.relatedTarget. So when clicking the link, e.relatedTarget should get populated with the link element, so in your blur handler, you can choose not to hide the container if the element clicked is within the container (or compare it directly with the link):
$('#ShippingGroup').blur(function(e)
{
if(!e.relatedTarget || !e.currentTarget.contains(e.relatedTarget)) {
// Alt: (!e.relatedTarget || $(e.relatedTarget) == $('.ShippingGroupLinkList'))
$('#ShippingGroupListWrapper').css('display','none'); // hide it.
}
}
(relatedTarget may not be supported in older browsers for blur events, but it appears to work in latest Chrome, Firefox, and Safari)
If this.menuTarget.classList.add("hidden") is the blur behavior that hides the clickable menu, then I succeeded by waiting 100ms before invoking it.
setTimeout(() => {
this.menuTarget.classList.add()
}, 100)
This allowed the click event to be processed upon the menuTarget DOM before it was hidden.
I know this is a later reply, but I had this same issue, and a lot of these solutions didn't really work in my scenario. mousedown is not functional with forms, it can cause the enter key functionality to change on the submit button. Instead, you can set a variable _mouseclick true in the mousedown, check it in the blur, and preventDefault() if it's true. Then, in the mouseup set the variable false. I did not see issues with this, unless someone can think of any.
I have faced a similar issue while using jQuery blur, click handlers where I had an input name field and a Save button. Used blur event to populate name into a title placeholder. But when we click save immediately after typing the name, only the blur event gets fired and the save btn click event is disregarded.
The hack I used was to tap into the event object we get from blur event and check for event.relatedTarget.
PFB the code that worked for me:
$("#inputName").blur(function (event) {
title = event.target.value;
//since blur stops an immediate click event from firing - Firing click event here
if (event.relatedTarget ? event.relatedTarget.id == "btnSave" : false) {
saveBtn();
}
});
$("#btnSave").click(SaveBtn)
As already discussed in this thread - this is due to blur event blocking click event when fired simultaneously. So I have a click event registered for Save Btn calling a function which is also called when blur event's related Target is the Save button to compensate for the click event not firing.
Note: Didnt notice this issue while using native onclick and onblur handlers - tested in html.
