Twitter Bootstrap SelectPicker onchange function not being called
提问by Tim
So I have a simple select list
所以我有一个简单的选择列表
<select id="themes" class="selectpicker">
<option selected>mkl-ambiance</option>
<option>default</option>
<option>ambiance</option>
<option>blackboard</option>
</select>
and a small snippit of jquery
和一小段 jquery
$("#themes").change(function() {
var theme = $("#themes").val();
editor.setOption("theme", theme);
});
if I remove class="selectpicker"from the select the call back works as expected.
I even added onchange="doMyFunctionand changing $("#themes").change(function() {to function doMyFunction() {and that still didn't work. Is there some bootstrap magic I'm missing to get this to work properly?
如果我class="selectpicker"从选择中删除回调按预期工作。我什至添加onchange="doMyFunction并更改$("#themes").change(function() {为 function doMyFunction() {，但仍然无效。是否有一些引导魔法让我无法正常工作？

This is because Selectpicker generates <ul>and <li>tags and keeps the <select>and <option>aside. It adds 'rel' attribute to each <li>element for you to know which option is selected in relation to the selected <li>.
这是因为 Selectpicker 生成<ul>并<li>标记并保留<select>和<option>。它为每个<li>元素添加了 'rel' 属性，以便您了解与所选<li>.
Anyways, you should either use an official onChange event from the Selectpicker plugin, or do something like the following:
无论如何，您应该使用 Selectpicker 插件中的官方 onChange 事件，或者执行以下操作：
$('ul.dropdown-menu.selectpicker li').on('click', function () {
var selectedValue = $($('select.selectpicker option')[$(this).attr('rel')]).val();
});
