VueJs dynamic v-on event possible?

Question

Is it possible to set dynamic on event in VueJS? I try to build a dynamic form as component with inputs that can listen on everything. Here an example:

import Vue from 'vue';

let formItems = {
  {type: 'checkbox', id: 'some-id', on:'change', model: 'someId'},
  {type: 'url', id: 'another-id', on:'keyup', model:'anotherId'},
};

let params = {
  someId: true,
  anotherId: 'http://www.example.com',
};

new Vue({
  el: '#app',
  data: {
    formItems: formItems,
    params: params,
  },
  methods: {
    checkInputParams(e) {
      e.preventDefault();
      // Do some stuff.
    }
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.3.4/vue.js"></script>

<div id="app">
  <div class="form-group" v-for="item in formItems">
      <input type="checkbox" <!-- Also need a workaround for dynamic type and v-model -->
          :id="item.id"
          :class="(item.class ? item.class : '')"
          :title="(item.title ? item.title : '')"
          :placeholder="(item.placeholder ? item.placeholder : '')"
          :autocomplete="(item.autocomplete ? item.autocomplete : false)"
          :disabled="(item.disabled ? item.disabled : false)"
          :max="(item.max ? item.max : '')"
          :min="(item.min ? item.min : '')"
          :maxlength="(item.maxLength ? item.maxLength : '')"
          :multiple="(item.multiple ? item.multiple : '')"
          :name="(item.name ? item.name : '')"
          :readonly="(item.readonly ? item.readonly : false)"
          :required="(item.required ? item.required : false)"
          v-on="{{ item.on }}:checkInputParams" <!-- Here I try the dynamic v-on -->
          v-model="params[item.model]"/>
  </div>
</div>

Is it possible to set a dynamic v-on event like v-on="<variable>:<function>"?

Answer 1

From Vue 2.4.0+, v-on accepts an object syntax

Refer this documentation

<button v-on="{ mousedown: doThis, mouseup: doThat }"></button>
