从外部调用bootstrap typeahead updater函数。

Is there is a way for me to access the updater function from outside of the typeahead scope ?

是否有一种方法可以让我从typeahead范围之外访问updater函数?

My current example is that in the updater function, I have some custom logic that creates some html and appends it to the body such as with the following snippet example:

我现在的例子是，在updater函数中，我有一些自定义逻辑，创建一些html并将其添加到正文，例如下面的代码片段示例:

 updater: function(item){
                $input = $('<span/>',{
                   class:'label label-info',
                   text:item,
                   style:'margin-left:4px'
                 });
                ...
                $('#tagContainer').append($input);

             }

Now my question is: Is it possible for me to link this function to a button so that it is triggered when the button is clicked, considering that I will pass it the 'item' parameter ?

现在我的问题是:我是否可以将这个函数链接到一个按钮上，这样当按钮被单击时它就会被触发，考虑到我将把它传递给它的“item”参数?

I guess this problem involves something about functions scope, and this is where my knowledge lack, and need some insight.

我想这个问题涉及到功能范围，这是我的知识缺乏的地方，需要一些洞察力。

Define it as a separate function:

将其定义为一个单独的函数:

function appendInput(item) {
   //same contents
}

update: appendInput ...

$("button").on('click', function () { appendInput(this); });
