改正下列代码中的错误：_.api('offBluetoothAdapterStateChange').then(__ => __).catch(__ => __); _.on('onBluetoothAdapterStateChange','' ,res => { this.bm.log('onBluetoothAdapterStateChange', res); if (res.available && !this.isAvailableAdapter) { this.isAvailableAdapter = true; this.callBackConnectStatus(SuccessCallbackEvent.Success_ConnectStatus_CB_PowerOn); } else if (!res.available) { this.isAvailableAdapter = false; // 支付宝小程序当蓝牙适配器关闭，再次进行蓝牙操作需要重新打开，微信只需要打开一次就行 _.getAppPlatform() === 'ant' && (this.isInitializedAdapter = false); this.bm.connectStatus = ConnectStatus.disconnected; this.callBackConnectStatus(ErrorCallbackEvent.Error_ConnectStatus_CB_PowerOff); } });

小程序代码: “ openAndListenBluetoothAdapter() { // 未初始化蓝牙适配器，打开蓝牙适配器 if (!this.isInitializedAdapter) { // // 监听蓝牙适配器状态 _.api('onBluetoothAdapterStateChange', 'onBluetoothAdapterStateChange') .then( => ) .catch( => ); _.on('onBluetoothAdapterStateChange', 'onBluetoothAdapterStateChange', res => { this.bm.log('onBluetoothAdapterStateChange', res); if (res.available && !this.isAvailableAdapter) { this.isAvailableAdapter = true; this.callBackConnectStatus(SuccessCallbackEvent.Success_ConnectStatus_CB_PowerOn); } else if (!res.available) { this.isAvailableAdapter = false; // 支付宝小程序当蓝牙适配器关闭，再次进行蓝牙操作需要重新打开，微信只需要打开一次就行 _.getAppPlatform() === 'ant' && (this.isInitializedAdapter = false); this.bm.connectStatus = ConnectStatus.disconnected; this.callBackConnectStatus(ErrorCallbackEvent.Error_ConnectStatus_CB_PowerOff); } }); // 先关闭再打开蓝牙适配器，避免出现某些机型打开无效的情况 return _.api('closeBluetoothAdapter') .then(__ => { // 打开蓝牙适配器 return _.api('openBluetoothAdapter') }).then(res => { this.bm.log('openBluetoothAdapter success', res); this.isInitializedAdapter = true; this.isAvailableAdapter = true; return Promise.resolve(); }).catch(e => { this.bm.log('openBluetoothAdapter fail', e); this.isInitializedAdapter = false; this.isAvailableAdapter = false; this.bm.connectStatus = ConnectStatus.disconnected; return Promise.reject(e); }) } else { return Promise.resolve(); } } ” 。提示错误“onOnBluetoothAdapterStateChange should accept a function instead of object” ，请修改

把代码中的： _.api('onBluetoothAdapterStateChange', 'onBluetoothAdapterStateChange') .then(__ => __) .catch(__ => __); 修改为： _.api('onBluetoothAdapterStateChange', res => { this....

const handleClose=(done)=> { this.$confirm('确认关闭？') .then(_ => { done(); }) .catch(_ => {}); }将这段代码改为vue3的写法

在Vue3中，代码需要使用Composition API进行重构。假设您已经将原始代码放入了一个名为MyComponent的组件中，可以使用以下代码重构： javascript import { defineComponent, ref } from 'vue'; export ...

DECLARE v_yclfmx number; v_wgclfmx number; if :new.jgbspsj != :old.jgbspsj then select sum(hj) into v_yclfmx from uf_jxjgshgcb_dt14 where mainid = :old.id; update uf_jxjgshgcb set jgbyclf = v_yclfmx where id=:old.id; select sum(hj) into v_wgclfmx from uf_jxjgshgcb_dt16 where mainid = :old.id; update uf_jxjgshgcb set jgbwgclf = v_wgclfmx where id=:old.id; end IF;

这段代码是一个 PL/SQL 的触发器，当一个数据行被修改（UPDATE）时，会检查其 jgbspsj 字段的值是否被改变。如果改变了，则会执行两个 SELECT 语句来计算该数据行对应的两个子表中 hj 字段的总和，并分别更新主表 uf...

例如，S → A b {B.in_num := A .num + 100} B { if B.num=0 then S.accepted := true else S.accepted := false }表示在S被归约为A b B时，如果B.num为0，则设置S.accepted为true，否则设置为false。这些语义动作...
