Filter input text only accept number and dot vue.js

You can write a Vue method and that method can be called on the keypress event. Check out this fiddle.

Update:

adding source code:

HTML

<div id="demo">
  <input v-model="message" @keypress="isNumber($event)">
</div>

Vue.js

var data = {
  message: 1234.34
}

var demo = new Vue({
  el: '#demo',
  data: data,
  methods: {
    isNumber: function(evt) {
      evt = (evt) ? evt : window.event;
      var charCode = (evt.which) ? evt.which : evt.keyCode;
      if ((charCode > 31 && (charCode < 48 || charCode > 57)) && charCode !== 46) {
        evt.preventDefault();;
      } else {
        return true;
      }
    }
  }
});
