Can Vue.js add commas while user typing numbers?

Morteza Negahi Source

I see this topic, But this is Jquery, How can I change it to Vue.js ? Is v-on supported in Vue.js Where is my mistake. Sorry for my terrible English.

<div id="vue">
    <input v-model="amountModel" v-on:keyup="AddCammas()" value="{{price}}">
</div>

<script>
   el: #vue,
   methods:{
      AddCammas : funtion(){
          if(event.which >= 37 && event.which <= 40) return;

          $(this).val(function(index, value) {
             this.message = this.amountModel
                .replace(/\D/g, "")
                .replace(/\B(?=(\d{3})+(?!\d))/g, ",");
           });
      } 
   }   
</script>

You don't need jQuery at all for this. You watch your variable, and in the watch function, compute the reformatted version, then set it back to your variable using nextTick (so it's not mutating before the watch is complete).

new Vue({
  el: '#vue',
  data: {
    price: 0
  },
  watch: {
    price: function(newValue) {
      const result = newValue.replace(/\D/g, "")
        .replace(/\B(?=(\d{3})+(?!\d))/g, ",");
      Vue.nextTick(() => this.price = result);
    }
  }
});
<script src="//cdnjs.cloudflare.com/ajax/libs/vue/1.0.28/vue.min.js"></script>
<div id="vue">
  <input type="text" v-model="price" />{{price}}
</div>

To people who are looking for doing mask for multiple fields then it's kinda pain to use watch, so may we can use v-money (docs included). And check the demo here.
