How can I use v-model with the Vue Options API effectively?

You can use v-model in the Vue Options API by binding it to data properties in your component. For example, if you have an input field, you can bind it like this: <input v-model='inputValue'> where inputValue is a data property.

Can you show me a complete example?

Sure! Here's a simple example:

new Vue({
  el: '#app',
  data() {
    return {
      inputValue: ''
    };
  },
  template: `<div><input v-model='inputValue' /><p>You typed: {{ inputValue }}</p></div>`
});

This will display whatever you type in the input field.

What if I want to use v-model with a checkbox?

For checkboxes, you can bind v-model to a boolean data property. For example:

new Vue({
  el: '#app',
  data() {
    return {
      isChecked: false
    };
  },
  template: `<div><input type='checkbox' v-model='isChecked' /> <p>Checked: {{ isChecked }}</p></div>`
});

This will update isChecked based on the checkbox state.

Can I use v-model with multiple checkboxes?

Yes! You can use v-model with an array to handle multiple checkboxes. For example:

new Vue({
  el: '#app',
  data() {
    return {
      selectedOptions: []
    };
  },
  template: `<div>
    <input type='checkbox' v-model='selectedOptions' value='Option 1' /> Option 1
    <input type='checkbox' v-model='selectedOptions' value='Option 2' /> Option 2
    <p>Selected: {{ selectedOptions }}</p>
  </div>`
});

This will allow you to select multiple options.
