clickOutSide

export const clickOutside = {
    // 初始化事件
    beforeMount(el, binding, vnode) {
        function handleClick(e) {
            // 如果为元素本身，则返回
            if (el.contains(e.target) || e.target.className.includes(binding.arg)) {
                return false;
            }
            // 如果绑定了函数，则返回执行
            binding.value(e);
        }
        el.__vueClickOutside__ = handleClick;
        document.addEventListener('click', handleClick);
    },
    // 解除事件监听
    unmounted(el, binding) {
        document.removeEventListener('click', el.__vueClickOutside__);
        delete el.__vueClickOutside__;
    }
};

使用

import { clickOutside } from "../directives.js";

export default {
	directives: { clickOutside },
}
