el-select滚动到底部加载更多

自定义指令：

directives: {
'loadmore': {
inserted(el, binding) {
const SELECTWRAP_DOM = el.querySelector('.el-select-dropdown .el-select-dropdown__wrap');
SELECTWRAP_DOM.addEventListener('scroll', function() {
const condition = this.scrollHeight - this.scrollTop <= this.clientHeight; if (condition) { binding.value(); } }); } }

el-select滚动到底部加载更多最先出现在Python成神之路。
