Tips for triggering a function when the range slider is adjusted

I'm looking to trigger a function whenever a user changes a range slider in my Vue.js project, and I also need to pass the new value to that function. The code snippet below shows what I have so far.


                  <div
                    class="title title--danger "
                    :style="{color: this.$themes.danger}"
                  >Set Value</div>
                  <va-slider
                    color="danger"
                    value-visible
                    v-model="value"
                  />

                 // Function definition 
              data(){
                return{
              value: '' 
                }
              },
              watch: {
                value(newVal, oldVal){
                  alert('value = ' + newVal);
                }
              } 

Answer №1

Within your current template, the binding of the value is already linked to a property on your Vue component (value) using the v-model directive within the <va-slider> element. You can take advantage of this setup by implementing a watcher that will be triggered whenever the value changes:

{
  data() {
    return { value: '' };
  },
  watch: {
    value(newVal, oldVal){
      alert('The updated value is ' + newVal);
    }
  }
}
