引导程序崩溃扩展时如何调用函数 [英] How do I call a function when bootstrap collapse expands

问题描述

我要激活此javascript:

I want to activate this javascript:

jsPlumb.repaintEverything();

...并打开一个警告框，上面写着我正在扩大！！！"当用户单击> 此小提琴

...and fire up an alert box saying "I'm expanding!!!" when a user clicks the button in this fiddle

有人知道如何实现这一目标吗?

Does anyone know how to achieve this?

推荐答案

您可以使用Bootstrap引发的shown.bs.collapse事件:

You can use the shown.bs.collapse event that Bootstrap raises:

$('#demo').on('shown.bs.collapse', function() {
    jsPlumb.repaintEverything();
});

更新了小提琴

请注意，元素展开动画完成后，会在 后触发此事件.如果要在动画开始时运行代码，请改用show.bs.collapse

Note that this event fires after the element expansion animation has completed. If you want to run the code as the animation starts, use show.bs.collapse instead
