Vue Js Check if a Variable is an Array: In Vue.js, you can use the Array.isArray()
method to check if a variable is an array or not. This method takes one parameter, which is the variable you want to check, and returns a boolean value. If the variable is an array, it will return true
, and if it’s not, it will return false
.
How can you check whether a variable is an array or not in Vue.js?
This is a Vue.js app that checks if “myArray” is an array using v-if directive. If it is an array, the message “myArray is an array!” will be displayed, otherwise, the message “myArray is not an array.” will be displayed. In this case, “myArray” is indeed an array, so the first message will be displayed.
Vue Js Check If a Variable is an Array Example
<div id="app">
<p v-if="Array.isArray(myArray)">myArray is an array!</p>
<p v-else>myArray is not an array.</p>
</div>
<script type="module">
const app = Vue.createApp({
data() {
return {
myArray: [1, 2, 3],
};
},
})app.mount('#app');
</script>
