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.
