手动调用jquery mouseover函数

Question

jQuery有一组函数，我想在其中手动调用onmouseover函数。

我的index.php由一个div组成，在该div中有一个像鼠标悬停事件上的DEMO这样的由内而外的过渡。 我想在单击按钮时控制从内到外的过渡。

当我搜索此主题时，我发现可以通过if($("#my_btn_id").trigger('mouseover')) 。 但我尝试过，但我找不到解决方案。

修改打开的css :hover将其更改为class .hover ，并使用jQuery切换

 $('.ch-item').on('click', function() { $(this).toggleClass('hover'); }); 

 .ch-item { cursor: pointer; width: 100%; height: 100%; border-radius: 50%; position: relative; box-shadow: inset 0 0 0 0 rgba(200, 95, 66, 0.4), inset 0 0 0 16px rgba(255, 255, 255, 0.6), 0 1px 2px rgba(0, 0, 0, 0.1);
