Select2 dropdown allow new values by user when user types
提问by Alireza Fattahi
The select2 component can be configured to accept new values, as ask in Select2 dropdown but allow new values by user?
select2 组件可以配置为接受新值，如Select2 下拉列表中所问但允许用户使用新值？
And you can see it at: http://jsfiddle.net/pHSdP/646/the code is as below:
你可以在：http: //jsfiddle.net/pHSdP/646/看到它，代码如下：
$("#tags").select2({
createSearchChoice: function (term, data) {
if ($(data).filter(function () {
return this.text.localeCompare(term) === 0;
}).length === 0) {
return {
id: term,
text: term
};
}
},
multiple: false,
data: [{
id: 0,
text: 'story'
}, {
id: 1,
text: 'bug'
}, {
id: 2,
text: 'task'
}]
});
The problem is that the new value is only added to the list if you enter new value and press enter, or press tab.
问题是只有在输入新值并按 Enter 或按 Tab 时，新值才会添加到列表中。
Is it possible to set the select2 component to accept this new value when use types and leave the select2. (Just as normal html input tag which keeps the value which you are typing when you leave it by clicking some where on the screen)
是否可以将 select2 组件设置为在使用类型时接受此新值并保留 select2。（就像普通的 html 输入标签一样，当你点击屏幕上的某个位置时，它会保留你正在输入的值）
I found that the select2 has select2-blurevent but I don't find a way to get this new value and add it to list?!
我发现 select2 有select2-blur事件，但我没有找到获取这个新值并将其添加到列表的方法？！

并且能够与现有选项一起提交多个新选项：
select2({tags: true, selectOnBlur: true, multiple: true})
