We can determine whether a checkbox is checked or not by binding a variable to a data property in your Vue component. Here’s an example of how to do this:

<template>
  <div>
    <label>
 <input type="checkbox" v-model="isChecked" @change="handleCheckboxChange" />
    Check this box
    </label>
    <p>Checkbox is checked: {{ isChecked }}</p>
  </div>
</template>


<script>
export default {
  data() {
    return {
      isChecked: false, // Initialize the checkbox state to unchecked
    };
  },
  methods: {
    handleCheckboxChange() {
      // This method will be called when the checkbox state changes
      console.log("Checkbox state changed. Checked:", this.isChecked);
    },
  },
};
</script>

In this example:

• We define a data property called isChecked and initialize it to false. This property will hold the state of the checkbox.
• We use the v-model directive to bind the isChecked data property to the checkbox. This two-way binding means that when the checkbox is checked or unchecked, the isChecked property will automatically update to reflect the current state of the checkbox.
• We display the current state of the checkbox using {{ isChecked }} in the template.

Now, isChecked will always reflect whether the checkbox is checked or not. You can use this value in your component’s logic or methods to perform actions based on the checkbox state.
