小程序中webview中有cover-view。动态改变cover-view里面的变量无法 更新视图。在ios手机没有问题，在安卓手机里面视图不更新。 <web-view    src="{{path}}">   <cover-view class="cheerTransmitShare">   <cover-view class="share_item"   bindtap="praiseDetail">   <cover-image  wx:if="{{praiseStatus==='0'}}"  src="/images/jnis/cheerActive.png"></cover-image>   <cover-image  wx:else src="/images/jnis/cheer.png"></cover-image>   <cover-view>{{praiseCount}}</cover-view>   </cover-view>   <cover-view   class="share_item"   bindtap="favoriteDetail">     <cover-image  wx:if="{{favoriteStatus==='0'}}"   src="/images/jnis/collectionActive.png"></cover-image>     <cover-image  wx:else  src="/images/jnis/collection.png"></cover-image>     <cover-view>{{favoriteCount}}</cover-view>   </cover-view>   <cover-view  class="share_btn_cover share_item share_btn">   <button hover-class="button-hover"   open-type="share"   bindtap="forwardDetail" >       <cover-view  class="share_box"  style="width:117rpx;height:50rpx">         <cover-image   class="share" src="/images/jnis/share.png"></cover-image>       </cover-view>   </button> </cover-view>   </cover-view > </web-view>

自己项目中，用到了webview去跳转到pc的某个界面，有时候点击webview的返回按钮要点击好多下 才能返回到我的小程序中，这该怎么办？ ———————————————— 版权声明：本文为CSDN博主「this指向谁」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/qq_43258005/article/details/105026087

// SDK // https://res.wx.qq.com/wwopen/js/jsapi/jweixin-1.0.0.js // https://open.work.weixin.qq.com/wwopen/js/jwxwork-1.0.0.js window.wx.invoke('getCurExternalContact', {}, (res) => { // 在windows客户端，有可能不会被触发   if (res.err_msg === 'getCurExternalContact:ok') {   console.log('获取外部联系人信息成功', res);     } else {   console.log('获取外部联系人信息失败');   } });

作为外围设备发送广播，可以成功发送，如下代码： startAdvertising() {      this.server.startAdvertising({       advertiseRequest: {         connectable: false,         beacon:{           uuid:uuid1,           major:3322,           minor:222         }       },       powerLevel: 'medium'     }).then(res => {       console.log('startAdvertising 广播成功', res)     }, res => {       console.log("fail: ", res)     })   }, 但是在搜索设备的时候，可以监听到广播，但是返回的数组长度为0：  wx.onBeaconUpdate((res)=> {                console.log('扫描到ibeacon设备'+JSON.stringify(res));               if (res && res.beacons && res.beacons.length > 0) {                 that.stopSearchBeacon();                         console.log(bleObj.uuid)                          }             }); onBeaconUpdate方法可以成功回调，但是res.beacons的长度为0 [图片] 代码片段：https://developers.weixin.qq.com/s/b7CrPumX7ryZ

password为true是可以调起安全键盘，需要明文时将password变为text，此时如何才能继续调起系统的安全键盘？
