再一个菜单上添加open-type="contact"，所有菜单都变成了进入客服事件

                <view class="item tc" v-for="(item,i) in order" :key="i" v-if="!item.unshowItem">  
                    <view class="" @click="navigateToHandle(item.router)" >  
                        <view class="">  
                            <image class='cell-hd-icon' :src='item.icon'></image>  
                        </view>  

                          <view @click.stop class="text contactbutee" v-if="i=='kefu'">  
                            <button    class="contactbut" open-type="contact" >客服</button>  
                          </view>  

                            <view class="text" v-else>  
                                <text  class="">{{item.name}}</text>  
                            </view>  
                    </view>  

                </view>
