运行如下代码 就报错
positionChoose: function () { var that = this; wx.chooseLocation({ success: function (res) { console.log(res); that.setData({ positionData: res.name || res.address }) }, fail: function () { // fail }, complete: function () { // complete } })}, |
你好，开发者工具在 v2.4.4 和 v2.5.0 的基础库中只要发生切后台的行为，都会产生这个错误。真机上不会产生这个错误。
我们会在下个基础库版本中进行修复。
