jquery触发对焦点或点击操作，但不是两者 [英] jquery trigger action on focus or click but not both

问题描述

我有这个示例代码：

  $ myTrigger 
 .click（function（e）{
（b）
 
 
 
 
 
 $ b b $ b}）
  

目的是当你点击$ myTrigger时，如果，另一方面，你通过键盘（即焦点）选项卡，我想要完全相同的事情发生，所以我要求它点击。

捕获是如果我点击它，它也重点。所以这两个警报都消失了。

有没有办法防止焦点事件在点击时消失？

更新：

Ajm的评论让我想起我可能会问错事。

问题：触发焦点在javascript（和/或在jQuery？）。我可以假设每当我想要处理用鼠标点击和使用键盘插入时，focus（）事件将处理这两个？

或者它依赖于我附加事件的特定元素？ （在这种情况下$ myObject恰好是一个锚标签（链接）。

解决方案

jQuery有一个内置函数未使用所有通常称为 .one（）

  $ mytrigger.one（'click focus'，function（）{alert（event）;}） ; 
  

这只会触发一次，或者如果你想要后重新绑定。 >

I have this sample code:

$myTrigger
    .click(function(e){
         alert('click');
    })
    .focus(function(e){
         alert('focus');
         $(this).click()
    })

The intent is that I want something to happen when you click on $myTrigger. If, on the other hand, you tab onto it via the keyboard (ie, focus) I want the exact same thing to happen, so I ask it to click.

The catch is if I click on it, it also focuses. So both alerts are going off.

Is there a way to prevent the focus event from going off when clicking?

UPDATE:

Ajm's comment got me thinking that I'm maybe asking the wrong thing.

Question: Does a click event always also trigger focus in javascript (and/or in jQuery?). Can I assume whenever I want to handle both clicking with the mouse and tabbing-in with the keyboard, the focus() event will handle both?

Or is it dependent on the particular element that I'm attaching the events to? (In this case $myObject happens to be an anchor tag (link).

解决方案

jQuery has a built-in functon for this that's not used all that often called .one()

$mytrigger.one('click focus', function() { alert("event"); });

This will only trigger once, or you can re-bind if you want afterwards.
