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，绑定(bind)了 2 个操作，一个是单击操作，一个是焦点移出。 单击操作会打开一个弹出窗口。并且焦点移出验证弹出窗口中的表单。我需要先执行 clik 操作，然后再将焦点移出。
问题是当弹出窗口打开时，会调用所有三个函数。
event.stopPropagation().preventDefault().stopImmediatePropagation(); 因此焦点在 Chrome 中不会触发。
在 IE10 和 Firefox 中效果很好。
我可以重写event.stopPropagation().preventDefault().stopImmediatePropagation()的jQuery基本函数来不申请该按钮吗？
也许三个都行？
我尝试过这个:
(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，但我可以控制焦点移出，我做了一些测试，我看起来 Chrome 没有看到焦点移出事件，因为该元素在发生焦点移出(它是一个弹出按钮)。 我设法用鼠标移出事件调用我的函数，但这在 IE 上不起作用，所以我必须为 IE 和 Chrome、Firefox、Safari 绑定(bind)单独的事件监听器。 您能帮忙提供一些浏览器检测示例吗？
更新2:
我的问题通过弹出元素的不同监听器解决了。例如:
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");
}); */

你是这个意思吗？
