it should be your changes to the data that lead to the redrawing of the entire array UI.
vue2 there is a corresponding solution ide/list.html-sharpkey" rel=" nofollow noreferrer "> vue document
to put it simply, when the v-for loop, each bind a different key value, when the data changes, it will only redraw the UI, corresponding to the key to reduce performance loss, and there will be no flash problem of lz.
