Vue js apply filter on v-model in an input field

Question

Hope someone can help me! I have made a directive wrapping the Jasny Bootstrap Plugin more specifically the input-mask thing and everything goes well!

Now I have made a

I had a similar problem when I wanted to uppercase an input value.

This is what I ended up doing:

// create a directive to transform the model value
Vue.directive('uppercase', {
  twoWay: true, // this transformation applies back to the vm
  bind: function () {
    this.handler = function () {
      this.set(this.el.value.toUpperCase());
    }.bind(this);
    this.el.addEventListener('input', this.handler);
  },
  unbind: function () {
    this.el.removeEventListener('input', this.handler);
  }
});

Then I can use this directive on the input field with a v-model.

Now, whenever I type into this field or change someData, the value is transformed to uppercase.

This essentially did the same thing as I hoped v-model="someData | uppercase" would do. But of course, you can't do that.

In summation: make a directive that transforms the data, not a filter.
