最近要搞个外贸网站，找到了 领添，它做的蛮好的，所以当即决定抄它的。

项目用vue-cli4 + ts开发，vue也有好久没用了，发展还蛮快，配合 ts 写法又不同了。

没有引入任何ui库，所以那些样式组件什么的只能自己撸了，自己撸也挺好的，这不，又踩坑了嘛。

我好像就没自己独立写过下拉框组件，我想到了用 mouseover 和 mouseout，结果死活不行，总是有问题，后来试着用 mouseleave 替代 mouseout，果然ok了！

归根结底在于，我用的事件捕获，mouseleave 离开这个包裹着的元素才会触发，但是 mouseout 离开其子元素也会触发，我就说怎么老是执行的，果然开源组件用多了，自己也就慢慢懒散了！
