简单实现一个ES5 Vue Dialog 插件

var pconfirm = Vue.extend({
  template: ‘    <transition name="fade">        <div v-show="isShowFlag">          <div class="com-comfirm">              <div class="com-comfirm-content">                <div class="com-comfirm-icon-wrap">                  <img :src="icon" >                </div>                <div class="com-comfirm-desc">                  {{desc}}                </div>              </div>              <div class="com-comfirm-foot" v-show="!autoDisappear">                <div class="com-comfirm-cancel" v-show="cancelShow" @click="handleCancel">取消</div>                <div @click="handleSure">确定</div>              </div>            </div>            <div class="my-mask"></div>        </div>    </transition>‘,
