Vue Js pass parameters in computed properties
Vue.js: Passing Parameters in Computed Properties
To pass parameters in computed properties in Vue.js, you can use a combination of methods and computed properties. Here are the steps to achieve this:
Step 1: Define a method in the Vue component that takes the parameter you want to pass.
Step 2: In the computed property, call the method defined in the previous step and pass the parameter as an argument.
Step 3: Use the computed property in your template or in other computed properties to access the computed value.
Here's an example to illustrate these steps:
<template>
<div>
<p>{{ fullName }}</p>
</div>
</template>
<script>
export default {
data() {
return {
firstName: 'John',
lastName: 'Doe'
};
},
methods: {
getFullName(title) {
return `${title} ${this.firstName} ${this.lastName}`;
}
},
computed: {
fullName() {
return this.getFullName('Mr.');
}
}
};
</script>
In this example, we have a Vue component with a fullName
computed property. Inside the fullName
computed property, we call the getFullName
method and pass the parameter 'Mr.'
. The getFullName
method takes the title
parameter and returns the full name by concatenating it with the firstName
and lastName
data properties.
Finally, we use the fullName
computed property in the template by using the {{ fullName }}
syntax. This will display the full name with the title as "Mr. John Doe".
By following these steps, you can pass parameters in computed properties in Vue.js and dynamically compute values based on those parameters.
