在引导中选择项目时,如何更改下拉列表的主显示

问题描述:

这是以下 http://jsfiddle.net/coderslay/enzDx/

只要点击一个项目,我正在尝试更改文本选择

I am trying to change the text Select as soon as an item is clicked

所以如果我从列表中选择一个,则应显示一个

So if i select One from the list then One should be displayed.

如何做?

我所做的唯一改变您的HTML将元素ID dropdown_title span 标签包含文本选择,以便更新更容易

The only change I made to your HTML was to wrap the text "Select" with span tags with the element ID dropdown_title so it was easier to update.

JavaScript:

JavaScript:

$('.dropdown-toggle').dropdown();
$('#divNewNotifications li').on('click', function() {
    $('#dropdown_title').html($(this).find('a').html());
});​

基本上我所做的是每当用户单击列表项,我将使用最后一个项目中包含的链接文本更新下拉标题文本。

Basically all I'm doing is whenever the user clicks on a list item, I update the drop-down title text with the text of the link contained in the last item.
