我正在尝试修改Jira Tempo插件的计划工作表单。所以在节奏时间表页面 我有一个按钮，它有2个动作绑定，一个是点击动作，一个是焦点。 点击操作会打开一个弹出窗口。并且焦点将在弹出窗口中验证表单。我需要首先执行clik操作，然后重点关注。
问题是当弹出窗口打开时，会调用所有这三个函数。
event.stopPropagation().preventDefault().stopImmediatePropagation();因此焦点不会在Chrome中触发。
在IE10和Firefox中效果很好。
我可以覆盖event.stopPropagation().preventDefault().stopImmediatePropagation()的jQuery基本功能而不申请该按钮吗？
这三个，也许？
我试过了：
(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;
}
})();
更新：
我无法控制点击功能的作用，但是我已经控制了焦点，我做了一些测试，我看起来Chrome没有看到焦点输出事件，因为元素在隐藏之前被隐藏发生焦点（它是一个弹出按钮）。 我设法用鼠标输出事件调用我的函数，但这不适用于IE，因此我必须为IE和Chrome，Firefox，Safari绑定单独的事件监听器。 你能帮忙解决一些浏览器检测实例。
更新2：
我的问题通过弹出元素的不同侦听器解决了。例如：
jQuery(document).ready(function ($) {

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");

你的意思是？
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' />

从这个问题来看，目前还不清楚你控制的代码。我正在读取可能您控制与按钮的click事件绑定的函数的行，但是您不控制与focusout事件绑定的函数，这就是您需要解决这些调用的原因。
如果您想控制事件的执行并确保首先发生事件，只要事件属于同一类型，就可以使用jQuery.bindUp这样的事情来执行此操作。 。这样，你就不在乎其他处理程序是否试图调用stopPropagation等，因为你的处理程序无论如何都会先执行。
鉴于此，是否可以重构您的代码，以便您控制的逻辑（首先需要发生的部分！）与现有事件处理程序具有相同的事件类型，然后使用jQuery.bindUp确保它在您无法控制的事件处理程序之前执行？只要相关业务逻辑被移动到focusout事件，您仍然可以在需要时绑定到click事件。
（如果我的假设不正确，如果您可以更新问题以更详细地描述问题约束，将会很有帮助。）
