In Vue.js, you can use computed properties to calculate and return data based on other data in your component. Computed properties have a getter function that returns the computed value.


To access a computed property in a method, you simply call the computed property as a function in the method. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26

<template>
  <div>
    <p>Computed Property: {{ computedProperty }}</p>
    <button @click="getComputedProperty">Get Computed Property</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      dataValue: 10
    };
  },
  computed: {
    computedProperty() {
      // Access other data values and perform calculations here
      return this.dataValue * 2;
    }
  },
  methods: {
    getComputedProperty() {
      // Call the computed property as a function in the method
      const computedPropertyValue = this.computedProperty();
      console.log("Computed Property Value:", computedPropertyValue);
    }
  }
};
</script>


In this example, we have a computed property called computedProperty that returns the value of dataValue multiplied by 2. The getComputedProperty method is called when the button is clicked, which then calls the computedProperty as a function and logs the computed value to the console.
