uniapp开发在hbuilderX上运行到小程序后，方法里自动生成var _this = this；导致自己申明的var that = this不能使用，值取不出来
使用uniapp运行到小程序后，方法里为什么会自动生成var _this = this？Why is var _this = this automatically generated in the method after running into a small program with uniapp?

After the uniapp development runs into the applet on hbuilderx, VaR is automatically generated in the method_ this = this； As a result, the declared var that = this cannot be used and the value cannot be taken out

没看懂你这that声明了有什么用，直接用this不行？var _this = this这行代码看着也不影响你的
