//index.js //获取应用实例 const app = getApp() Page({ data: { }, onLoad: function () { wx.openBluetoothAdapter({ success: function (res) { console.info(res); }, fail: function (res) { console.info(res); wx.showModal({ title: '提示', content: '监测到系统未开启蓝牙，请前往设置开启蓝牙模块！', }) } }) wx.onBluetoothAdapterStateChange(function (res) { console.log(`adapterState changed, now is`, res) if (res.available) { wx.showToast({ title: '蓝牙已开启' }); } else { wx.showToast({ title: '蓝牙已关闭' }); } }) wx.startBluetoothDevicesDiscovery({ success: function (res) { console.log(res) } }) setTimeout(function (res) { wx.getBluetoothDevices({ success: function (res) { console.log(res) } }) }, 10000); wx.onBluetoothDeviceFound(function (devices) { console.log('new device list has founded') console.dir(devices); wx.getBluetoothDevices({ success: function (res) { console.log(res) } }) }) }, getBluetoothDevices: function () { let that = this; wx.getBluetoothDevices({ success: function (res4) { console.log(res4); for (let item of res4.devices) { console.log(item.name.trim()) console.log(item.name.trim().length) } } }) }, startsearch:function(){ wx.startBluetoothDevicesDiscovery({ success: function (res) { console.log(res) } }) }, }) 我这样写得到的array永远为0，用了多个真机调试都没用，是不是蓝牙模块有问题？

国外能使用wx.openLocation(OBJECT) API查看位置吗？

    var scrollTop = 0;     var query = wx.createSelectorQuery()     query.selectViewport().scrollOffset();     query.exec(function (res) {       scrollTop = res[0].scrollTop // 显示区域的竖直滚动位置       that.data.scrollTop = scrollTop;     }) 在1.4.3 res有值，1.5还是没有值啊
