将当前选定的列表项从bootstrap插件selectpicker传递到JS(Pass currently selected list item from bootstrap plugin selectpicker into JS)

 我是JS新手，我正在尝试使用bootstrap中的selectpicker插件从选择列表中访问选定的值。 
 
 目前，我的代码为我提供了整个列表，而不仅仅是当前所选的项目。 
 
<div class="form-group">
                <select class="selectpicker" name="applicationSelect">
                    <option value="1">app 1</option>
                    <option value="2">app 2</option>
                    <option value="3">app 3</option>
                </select>
            </div>
 
 然后在我的script.js文件中，我有： 
 
var appName = $('select[name=applicationSelect]').val(1).text();
 
 然后，检索到的值将基于Ajax事件，但我正在努力寻找一个可行的示例来完成我正在尝试的事情。 
 
 如何仅检索当前选定的项目？ 

I'm new to JS, I'm trying to access a selected value from a select list using the selectpicker plugin from bootstrap.
 
Currently my code gives me the entire list rather than just the currently selected item.
 
<div class="form-group">
                <select class="selectpicker" name="applicationSelect">
                    <option value="1">app 1</option>
                    <option value="2">app 2</option>
                    <option value="3">app 3</option>
                </select>
            </div>
 
Then in my script.js file I have:
 
var appName = $('select[name=applicationSelect]').val(1).text();
 
The retrieved value will then be based onto an Ajax event, but I'm struggling to find a working example doing what I'm trying to do.
 
How do I retrieve only the currently selected item?
