vue. Vue cannot detect the change. I don't know if the value printed by console.log has not changed. Or the data on the page has not changed

directly changing the value in the data vue cannot be detected unless you use
so you can use this.$set (this.tranList,this.tranList [index], item+1)
there's nothing wrong with your current code No change can be detected by directly modifying the value Vue.set (this.tranList, 1, { }) is your data obtained by ajax? Is tranList set to null when data is initialized or does it not exist at all? If this property is not defined before ajax, it will not be monitored. You need to use this.$set ('tranList',data) to assign a value after ajax succeeds
as for checking the array,
forEach it actually means
this.tranlist [0] .value + = 1 Vue recursively handles data , so it's no problem
arr [0] = 1 the array can't be changed
arr [
you need to use the code
import Vue from 'vue'
method of Vue.
