Implementing conditional logic using v-if and v-else statements

I am currently diving into the world of vue.js! I have enrolled in a course on Udemy to expand my knowledge. While experimenting with basic conditional statements, specifically if-else statements, I encountered an issue. Despite following the instructions provided by the course instructor and implementing the exact same code as demonstrated, both the if and else conditions are being compiled. Below is the code snippet I used:

<html>
    <head>
        <title>If-Else</title>
        <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.11/vue.min.js">

    </script>
        </head>
        <body>
            <div id="app">
                <p v-if="rainy">The weather is rainy</p>
                <p v-else>The weather is sunny</p> 
            </div>
        </body>
        <script type="text/javascript">
        new vue({
            el: '#app',
            data: {
                rainy: false
            }
        });
        </script>
    </html>

Answer №1

There seems to be a small error in your code. Remember that Vue should start with an uppercase letter:

new Vue({
  // ...
})

If you check the Console (F12 or ctrl+shift+i), you might encounter this message:

Error: vue is not defined

Always remember that JavaScript is case-sensitive, so pay attention to variable names.

Answer №2

It is recommended to set up your data as a function when working with Vue.js. Additionally, make sure to refer to Vue as Vue instead of using lowercase vue.

new Vue({
        el: '#app',
        data: function() {
            return {
               sunny: true
            }
        }
    });
