v-else-if Directive in Vue.js
v-else-if directive is a Vue.js directive used to toggle the display CSS property of an element depending on a condition when the if condition is not satisfied. First, we will create a div element with id as app and let’s apply the v-else-if directive to an element with data. Now we will create this data by initializing a Vue instance with the data attribute containing the value.
Syntax:
v-else-if="data"
Parameters: This function accepts a single parameter which is data or a condition.
Example 1: This example uses Vue.js to show an element with v-else-if using arithmetic conditions.
<!DOCTYPE html> <html> <head> <title> VueJS | v-else-if directive </title> <!-- Load Vuejs --> <script src= </script> </head> <body> <div style="text-align: center; width: 600px;"> <h1 style="color: green;"> zambiatek </h1> <b> VueJS | v-else-if directive </b> </div> <div id="canvas" style= "border:1px solid #000000; width: 600px;height: 200px;"> <div id="app"> <h2 v-if="data > 50"> data is greater than 50 </h2> <h2 v-else-if="data < 50"> data is smaller than 50 </h2> <h2 v-else> data is equal to 50 </h2> </div> </div> <script> var app = new Vue({ el: '#app', data: { data: 40 } }) </script> </body> </html> |
