修改折叠插件以与select = selected一起使用 [英] modify collapse plugin to work with select = selected
问题描述
我正在尝试使用<select>，以便在更改时隐藏/显示div.
I am trying to use a <select> so that on change it hide/shows a div.
我想使用twitter bootstrap崩溃插件.
I want to make use of the twitter bootstrap collapse plugin.
在本示例中，我花了一半时间 http://plnkr.co/edit/9lPe61? p =预览
I have it half working with this example http://plnkr.co/edit/9lPe61?p=preview
但是，当您将selected添加到选择项时，它将破坏所有内容: http://plnkr. co/edit/w9XW8R?p = preview
But when you add selected to the select it breaks everything: http://plnkr.co/edit/w9XW8R?p=preview
<div class="accordion" id="accordion" >
<div class="accordion-group">
<select class="accordion-toggle">
<option value="1" data-toggle="collapse" data-parent="#accordion" data-target="#collapseOne">1</option>
<option value="2" data-toggle="collapse" data-parent="#accordion" data-target="#collapseTwo">2</option>
<option value="3" data-toggle="collapse" data-parent="#accordion" data-target="#collapseThree">3</option>
</select>
<div id="collapseOne" class=" collapse in">
<div class="accordion-inner">

JS-我想我需要添加到插件中以检查是否有selected="selected"，以便它也可以与selects一起使用，但是我不知道这应该去哪里?
JS - I guess I would need to add to the plugin to check if there is a selected="selected" so that it works with selects also, but I cant figure out where abouts this needs to go?

推荐答案
OP，
我认为这 http://plnkr.co/edit/qfB8Uf?p=preview是你所追求的.
I think this http://plnkr.co/edit/qfB8Uf?p=preview is what you're after.
...
$('document').ready(function () {
$(".accordion-dropdpwn").on('change', function (e) {
var selected_value = $(this).val(),
$target_elem = $('a[href="' + selected_value + '"]');
$target_elem.trigger('click');
});
$('.accordion-toggle').on('click', function () {
var selected_value = $(this).attr('href');
$(".accordion-dropdown option").removeAttr('selected');
$('option[value="' + selected_value + '"]').attr('selected', 'selected');
});
$(".accordion-dropdown").trigger('change');
});
...
简报
由于<select>的change事件返回了所选option(子级)的value，因此我填充了对手风琴<a>的引用，当用户更改下拉菜单时，该手风琴<a>应该受到影响-下.
Brief
Since the change event for the <select> returns the value of the selected option (child), I stuffed a reference to the accordion <a> that should be affected when the user changes the drop-down.
有了参考资料后，我们只需触发该项目的点击事件即可.另一个重要的方面是确保在加载页面时，手风琴将反映select的当前状态-也就是说，任何option具有selected="selected"的状态都将处于打开/活动状态.
Once we have our reference, we simply trigger a click event on that item. The other important bit is making sure that when the page is loaded, the accordion will reflect the current state of the select — that is, whichever option has selected="selected" will be open/active.
最后，存在双向控制.由于如果用户更改了<select>，则手风琴也会更改，因此希望单击手风琴可以更改<select>.
Lastly, there is bi-directional control. Since if the user changes the <select>, the accordion changes, it's expected that clicking the accordion should change the <select>.
希望这会有所帮助.
