Vue.js-观看数据更改

Question

I added a Bootstrap Vue Table to my app and wanted to log when the user switches to another page using the built in pagination.

https://bootstrap-vue.js.org/docs/components/table/

For this, I added a @change that is supposed to listen and log the v-model of the pagination, currentPage . However, it seems to be called before currentPage is actually updated.

How can I properly listen to this updating?

This is what I have tried: https://jsfiddle.net/eywraw8t/394424/

 new Vue({ el: "#app", data: { totalRows: 50, perPage: 10, currentPage: 1 }, methods: { pagination() { console.log(this.currentPage); }, } }) 

 <div id="app"> <div> <b-pagination :total-rows="totalRows" :per-page="perPage" v-model="currentPage" @change="pagination" /> </div> </div>

You can watch currentPage

new Vue({
  el: "#app",
  data: {
   totalRows: 50,
   perPage: 10,
   currentPage: 1
  },
  watch: {
    currentPage: function (newVal) {
       console.log('Change to page', newVal)
    }
  },
  methods: {
    setTo() {
     this.currentPage = 1;
     console.log(this.currentPage);
    }
  }
})
