Creating a Vue.js component that animates text to fade in and out within a textarea when a button

I need assistance with updating a <textarea> element in my Vue application. Currently, I have the textarea bound to some data in my state. However, when a button is clicked, I want the existing data in the textarea to fade out and be replaced with new data that fades in.

HTML

<button id="submit-button" v-on:click="changeData">Change</button>

<textarea id="dataoutput" rows="14" cols="90" v-model="output" readonly>{{ output }}</textarea>

JS

var app = new Vue({
    el: '#app',
    data: {
        output: "Original data output here"
    },
    methods: {
        changeData: function() {
            // perform calculations
            this.output = // new data
        }
    }
});

I've been exploring Vue transitions and CSS animations but I'm struggling to implement the desired effect. Any guidance on how to achieve this would be greatly appreciated.

Here is a unique approach: Apply the style "color: transparent" to textarea, and it will appear like this:

// To eliminate Vue warning messages
Vue.config.devtools=false;
Vue.config.productionTip = false;

// Vue setup:
new Vue({
    el: '#app',
    data: {
        output: "Original data output here",
        fadeOut: false
    },
    methods: {
        changeData: function() {
          // Activate 'fade-out' class 
          this.fadeOut = true;
          // Wait 500ms for CSS animation (text fade out effect),
          // Then remove 'fade-out' class to restore text color
          setTimeout(() => {
            this.output = 'Some other text';
            this.fadeOut = false;
          }, 500);
        }
    }
});

#dataoutput {
  transition: color 0.5s; /* Text color transition duration = 500ms */
}

#dataoutput.fade-out {
  color: transparent; /* Set text color to transparent */
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<button id="submit-button" v-on:click="changeData">Change</button>

<textarea id="dataoutput" rows="14" cols="90" v-model="output" readonly v-model="output" :class="{'fade-out': fadeOut}"></textarea>
</div>
