Mini Program, after deleting a certain order data, the background deletes it, but the page is not deleted? I have used this.orderList.splice (_ index, 1) for the original order list data, but the page has not been deleted unless the page is refreshed and the data is reloaded
Mini Program needs setData to explicitly cover the data back, directly .splice () in Vue, but not in Mini Program.
the this.orderList that should be checked first, and the direction of this you should check.
is it in the wepy component? Try this.$root.$apply ();
this situation may be asynchronous. Just now you also said that refresh can only be performed by onload method. You can look for
such as
Page({
data: {
arr: ["1","2","3" ]
}
})
this.setData({
arr: this.data.arr.splice(0,1)
})API callback needs to re-setData your array
has it been solved? I also encountered the same problem
this.list = this.list.filter (item = > item.id! = = id);
this.$apply ();
