can we call parent method from child compponent

 Yes, in Vue.js it is possible to call a method defined in the parent component from a child component.

To do this, you can use an event to emit a message from the child component to the parent component, which triggers the parent method. Here are the basic steps to accomplish this:

1. Define a method in the parent component that you want to call from the child component.

php
<template>
  <div>
    <ChildComponent @custom-event="parentMethod"></ChildComponent>
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent
  },
  methods: {
    parentMethod() {
      // Do something in the parent component
    }
  }
};
</script>

In this example, we have defined a method called parentMethod in the parent component, which we want to call from the child component.

2. In the child component, define an event that will emit a message to the parent component when triggered.

php
<template>
  <div>
    <button @click="emitEvent">Call Parent Method</button>
  </div>
</template>

<script>
export default {
  methods: {
    emitEvent() {
      this.$emit('custom-event');
    }
  }
};
</script>

In this example, we have defined a method called emitEvent in the child component, which emits a custom event called custom-event when the button is clicked.

3. In the parent component, listen for the custom event emitted by the child component and trigger the parent method when the event is received.

php
<template>
  <div>
    <ChildComponent @custom-event="parentMethod"></ChildComponent>
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent
  },
  methods: {
    parentMethod() {
      // Do something in the parent component
    }
  }
};
</script>

In this example, we have added a listener for the custom-event in the parent component using the @custom-event="parentMethod" syntax. When the custom-event is emitted by the child component, the parentMethod is triggered in the parent component.

Note that you can also pass data from the child component to the parent component using the same event mechanism by passing the data as an argument to the $emit method.
