在Select2关闭事件触发后聚焦输入 [英] Focusing Input after Select2 close event fire

问题描述

我读了总是为< select>触发更改 - 事件，即使已经选中了单击的select2选项并且由于问题非常接近我的问题，我在那里问了我的问题，但没有提供答案。我的问题是我有一个由Select2构造的选择框和一个文本输入。我想要实现的是 Select2关闭（无论值是否更改）我的文字输入变为焦点。

I read always trigger "change"-event for <select>, even if the select2-option clicked is already selected and as the problem was so close to my issue I asked my question there but no answer provided. My problem is that I have a select-box constructed by Select2 and a text input. What I want to achieve is after Select2 closed (no matter the value is changed or not) my text input become focus.

所以我做了一些逻辑上很好的事情如下：

So I did something logically fine as follow:

$('#select').select2({placeholder: 'City'});
$('#select')
.on('select2-close', function (e) {
   $('#hey').focus();
});

正如您所看到的，文本输入不是接受焦点。在对Select2文档进行一些挖掘并检查文档的事件部分后，我意识到在Close事件之后，会自动触发Focus事件。这意味着在关闭Select2选择框后，它会自动聚焦。所以我将我的代码更改为：

As you can see, the text input doesn't accept focus. After some digging in Select2 document and inspecting Events part of documentation, I realized that after Close event, there is a Focus event fire automatically. It means that after you close a Select2 select-Box, it focuses itself. So I changed my code to something like this:

$('#select').select2({placeholder: 'City'});
$('#select')
.on('select2-close', function (e) {
       $('#select').blur();
})
.on('select2-blur', function(e) {
      $('#hey').focus();
});

它运作正常。现在我想知道我对Select2事件顺序的理解是正确的，或者我错过了中间的东西。

And it works just fine. Now I want to know that my understanding from Select2 order of events was correct or I missed something in the middle.

推荐答案

拿一个看这里，这个问题已经有了答案：
关闭后模糊select2输入

take a look here, this question is already has an answer: Blur select2 input after close

.on("select2-close", function () {
    setTimeout(function() {
        $('.select2-container-active').removeClass('select2-container-active');
        $(':focus').blur();
        $("#elementid").focus();
    }, 1);
});

elementid 是你想要的id元素在select2 closese之后关注。
我刚刚将 $（＃elementid）。focus（）; 添加到链接的答案。

elementid is the id element you want to be focused after select2 closese. i have just added $("#elementid").focus(); to the answer at link.
