问题
I am trying to modify Jira Tempo plugin's plan work form. So in the tempo time sheet page I have a button who has 2 actions bind-ed, one is a click action and one is a focus out. the click action opens a popup. and the focus out verifies the form in the popup. I need the clik action to be executed first and then the focus out.
The problem is when the popup opens there is a call to all of the three functions.
event.stopPropagation().preventDefault().stopImmediatePropagation(); so the focus out does not fire in chrome.
In IE10 and Firefox works great.
Can i override jQuery basic function ofevent.stopPropagation().preventDefault().stopImmediatePropagation() to do not apply for that button?
all three, maybe?
I tried this:
(function () {
jQuery.Event.prototype = {
isDefaultPrevented: returnFalse,
isPropagationStopped: returnFalse,
isImmediatePropagationStopped: returnFalse,
stopPropagation: function () {
if (jQuery('#tempo-plan-button').hasClass(this.currentTarget.className)) {
} else {
var e = this.originalEvent;
this.isPropagationStopped = returnTrue;
if (e && e.stopPropagation) {
e.stopPropagation();
}
}
},
preventDefault: function () {
if (jQuery('#tempo-plan-button').hasClass(this.currentTarget.className)) {
} else {
var e = this.originalEvent;
this.isDefaultPrevented = returnTrue;
if (e && e.preventDefault) {
e.preventDefault();
}
}
},
stopImmediatePropagation: function () {
if (jQuery('#tempo-plan-button').hasClass(this.currentTarget.className)) {
} else {
var e = this.originalEvent;
this.isImmediatePropagationStopped = returnTrue;
if (e && e.stopImmediatePropagation) {
e.stopImmediatePropagation();
}
this.stopPropagation();
}
}
};
function returnFalse() {
return false;
}
function returnTrue() {
return true;
}
})();
UPDATE:
I don't have control on what the click function does, but i have control on the focus out, I have made some test and i looks like Chrome does not see the focus out event, because the element is hidden before the focus out occurs ( it is a popup button). I managed to call my functions with mouse out event but this does not work on IE so I have to bind separate event listener for IE and Chrome,Firefox,Safari. Can you help with some browser detection examples.
UPDATE 2:
My problem solved with a different listener to the popup element. ex:
jQuery(document).ready(function ($) {
var currentUser = null;
var selected = null;
var opened = null;
var formOpened = null;
var activityField = null;
var activitySelected = null;
var popupBody = null;
var formOpened = null;
var periodCheckbox = null;
var dateField = null;
var endDateField = null;
var plannedHours = null;
var periodselected = null;
var days = 1;
var startdate = 0;
var enddate = 0;
var planButton = $('#tempo-plan-button');
//this is the default LM-Holiday activity ID set this
value to corespond with the value on jira tempo form.
var holidayid = "10100";
var holidaysLeft = 21; /*
$('#tempo-plan-button').click(function () {
alert("click event");
});
$('#tempo-plan-button').focusin(function () {
alert("focus event");
});
$('#tempo-plan-button').hover(function () {
alert("hover event");
});
$('#tempo-plan-button').mouseleave(function () {
alert("mouse leave event");
});
$('#tempo-plan-button').mouseout(function () {
alert("mouse out event");
}); */

回答1:
Did you mean this?
Event.prototype.stopPropagation = function(){ alert('123') }
$('input').on('click',function(e){
e.stopPropagation();
})<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type='button' value='click' />回答2:
From the question, it is unclear as to which code you control. I am reading between the lines that perhaps you control the function bound to the click event for the button, but you do not control the function bound to the focusout event, which is why you need to work around those calls.
If you want to control of execution of the events and make sure that yours happen first, it's possible to do this with something like jQuery.bindUp, just so long as the events are of the same type. In that way, you don't care if the other handler tries to call stopPropagation etc. because your handler will get to execute first anyway.
Given that, is it possible to restructure your code so that the logic you control (the part which needs to happen first!) is of the same event type as the existing event handler, and then use jQuery.bindUp to ensure that it gets executed before the event handler that you do not control? You can still bind to the click event if you need it, just so long as the dependent business logic is moved to the focusout event.
(If my assumptions are not correct, it would be helpful if you could update the question to describe the problem constraints in more detail.)
