roughly means that I encapsulate an interface to query the list of schools called schoolList.
when I choose the bindaddresChange method of the school address, I have changed the selectaddres, and agreed to it in the first step. I have just chosen the address. However, when I call the schoolList method to filter below, the value of selectaddres is not what I just selected. I know that the this.setData is asynchronous. The callback function can be written in this.setData ({userInfo: userInfo}, callback)) for online query, but it still doesn"t work. Has anyone ever encountered such a problem?
