Get the clicked object that triggered jquery blur() event
提问by pillarOfLight
Suppose I do this:
假设我这样做：
$(target).blur(function(e){
//do stuff
});
Is there a way to fetch the object that was clicked on in order to trigger the blur action?
有没有办法获取被点击的对象以触发模糊动作？
I tried using e.target, but that appears to be returning the object attached to the blur action rather than the clicked object.
我尝试使用e.target，但这似乎是返回附加到模糊动作的对象而不是单击的对象。

If I understand your question correctly, this should do it:
如果我正确理解您的问题，则应该这样做：
$(function() {
var clicky;
$(document).mousedown(function(e) {
// The latest element clicked
clicky = $(e.target);
});
// when 'clicky == null' on blur, we know it was not caused by a click
// but maybe by pressing the tab key
$(document).mouseup(function(e) {
clicky = null;
});
$(target).blur(function(e) {
console.log(clicky);
});??
});

The trick is to wait an extra tick:
诀窍是等待一个额外的滴答声：
$(el).blur(function (event) {
// If we just hangout an extra tick, we'll find out which element got focus really
setTimeout(function(){
document.activeElement; // This is the element that has focus
},1);
})

Inside an event handler, thiswill be the element the event is bound to, and e.targetwill be the element that triggered the event (may or not be the same as this).
在事件处理程序中，this将是事件绑定到e.target的元素，并将是触发事件的元素（可能与 相同，也可能不同this）。
You are handing a blurevent, not a clickevent. So, inside your event, you will have the element that you blured. If you want the clicked element, you'd need another event to get that.
您正在处理一个blur事件，而不是一个click事件。因此，在您的事件中，您将拥有您blur编辑的元素。如果你想要clicked 元素，你需要另一个事件来获得它。
blurcan be triggered by other events, such as focusing something; not just clicking on something. So, there is no way to get the element that "caused the blur".
blur可以由其他事件触发，例如聚焦某物；不只是点击某些东西。因此，无法获取“导致模糊”的元素。

Using this within blurhandler function will give you the bluredelement.
在blur处理程序函数中使用 this将为您提供blured元素。
$(target).blur(function(e){
var bluredElement = this; // dom element
// To make a jQuery object
var bluredElement = $(this);
});
Within blurevent you can't catch the clicked element. To get the clicked element you need clickevent. For example:
在blur事件中，您无法捕获单击的元素。要获取clicked 元素，您需要click事件。例如：
$(element).click(function() {
var clickedElement = this;
});
And to get the focused element you can use :focusselector like: $(':focus')will returns you focused element in document.
要获得焦点元素，您可以使用:focus选择器，例如：$(':focus')将在文档中返回焦点元素。
