我的网页上有一个Bootstrap
collapse panel.我需要在转换完成后面板完全展开后执行一个函数.我找到了这个示例,说明当面板折叠并添加hidden.bs.collapse时如何访问回调.

但是,当应用.collapse.in类时,我似乎无法触发类似的代码.
$('#collapseExample').on('.collapse.in',function(){
alert("hi");
});
我还发现这个代码使用promises在切换类后触发函数.它应该等到所有动画完成. jquery function on toggleClass complete?这对我的问题似乎也不起作用.
这段代码尝试了jQuery promise技术.理想情况下,它会在面板完成扩展后添加类.red但会立即触发.

$(document).on('click','.btn',function(){
$('#collapseExample').collapse("toggle").promise().done(function () {
$('.well').addClass('red');
})
});
解决方法
您可以使用显示的动画完成后触发的
event handler
$('#collapseExample').on('shown.bs.collapse',function() {
snippet.log("shown");
}).on('show.bs.collapse',function() {
snippet.log("show");
});
