The click event handler in a basic Vue application is failing to work with a button

In my Vue.js project, I have implemented a button that toggles the showProduct property between true and false when clicked. Here is the HTML code:

    <div id="app">
        <button v-on:click="showCheckout">Click Me</button>
    </div>

The Vue object looks like this:

    <script>
        const store = new Vue({
        el: '#app',
        data: {
            showProduct:true,
        },
    
        methods: {
            showCheckout: function() {
                this.showProduct = this.showProduct ? false : true;
            }
        }
        });
    </script>

Issue: Despite my attempts to fix it by adding

return this.showProduct = this.showProduct ? false : true;
, the property does not update correctly when the button is clicked. Specifically, clicking the button multiple times does not always change the value as expected.

If I use the Vue dev tools and select the Root component in the Components tab, the value updates only once when I click on it. Subsequent clicks of the button do not consistently update the value unless I first click the button on the page and then interact with the Root component in the dev tools window.

Everything is functioning smoothly. Feel free to test out this code snippet here for verification

const shop = new Vue({
        el: '#app',
        data: {
            displayItem:true,
        },
    
        methods: {
            showPurchase: function() {
                this.displayItem = this.displayItem ? false: true;
            }
        }
        });
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">
  <button v-on:click="showPurchase">Click Here</button>
  {{displayItem}}
</div>

Answer №2

There is no need for a specific method to handle single assignment. Take a look at the code snippet below:

new Vue({
  el: "#app",
  data() {
    return {
      showProduct: false
    }
  }
})


<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
 <div id="app">
    <h1 v-if="showProduct" > My product </h1>
    <button v-on:click="showProduct = !showProduct">Click Me</button>
</div>
