VueJS - check strings is includes in vuejs
To check if a string is included in Vue.js, you can use the includes()
method in JavaScript. Here's how you can do it step by step:
Step 1: Create a Vue.js component or add this code inside an existing component.
Step 2: Define a data property that holds the string you want to check. For example, let's say you want to check if the string "example" is included:
data() {
return {
myString: 'example'
}
}
Step 3: Use the includes()
method to check if the string is included. You can use this method in computed properties, methods, or directly in your template. Here's an example using a computed property:
computed: {
isStringIncluded() {
return this.myString.includes('example');
}
}
In the above code, the isStringIncluded
computed property returns true
if the string "example" is included in myString
, and false
otherwise.
Step 4: You can then use the computed property in your template or any other part of your Vue.js component:
<template>
<div>
<p>{{ myString }}</p>
<p v-if="isStringIncluded">The string is included.</p>
<p v-else>The string is not included.</p>
</div>
</template>
In the above code, the v-if
directive shows the message "The string is included" if isStringIncluded
is true
, and the v-else
directive shows the message "The string is not included" if isStringIncluded
is false
.
That's it! You have now checked if a string is included in Vue.js using the includes()
method.
