vue自定义弹窗点击除了自己区域外关闭弹窗

这里使用到vue的自定义指令

         <div class="item" v-clickoutside="clickoutside1">
            <div @click="opencity" class="text"
              :style="{ color: popup.iscitypop || okcitylist.length != 0 ? '#FF9500' : '#000000' }">选择地区
            </div>
            <i v-if="popup.iscitypop || okcitylist.length != 0" class=" el-icon-arrow-up"
              :style="{ color: popup.iscitypop || okcitylist.length != 0 ? '#FF9500' : '#000000' }"></i>
            <i v-else class="el-icon-arrow-down"
              :style="{ color: popup.iscitypop || okcitylist.length != 0 ? '#FF9500' : '#000000' }"></i>
            //绝对定位样式 popup.iscitypop true展示 false隐藏
            <div class="poppad" v-if="popup.iscitypop">
              <div class="tit" v-for="(item, index) in citylist" :key="index">
                {{ item.n }}
                <div class="cit">
                  <div class="items" :class="its.isactive ? 'active' : ''" v-for="(its, ind) in item.s" :key="ind"
                    @click.stop="changeCity(its, ind)">
                    {{ its.n }}
                  </div>
                </div>
              </div>
            </div>
          </div>


export default {
  directives: {
    clickoutside: {
      bind: function (el, binding, vnode) {
        function documentHandler(e) {
          if (el.contains(e.target)) {
            return false;
          }
          if (binding.expression) {
            binding.value(e);
          }
        }
        el.__vueClickOutside__ = documentHandler;
        document.addEventListener("click", documentHandler);
      },
      unbind: function (el, binding) {
        document.removeEventListener("click", el.__vueClickOutside__);
        delete el.__vueClickOutside__;
      }
    }
  },
}
