There are two callback functions in

vue:
one is Vue.nextTick (callback) . When the data is changed, the callback is executed after updating.
the other is Vue.$nextTick (callback) , the callback that is executed when the dom is changed.


  • scenarios with a large number of list items or performance pursuit (such as mobile) should use
  • vue itself will not automatically handle event delegates for you, but will only help you complete event-related bind operations
