How to Reset Text Fields with a Button Click in Vue.js?

I am currently working on a layout where I need to loop through text fields and buttons. How can I implement a function for each button that clears only the corresponding fields? Take a look at this fiddle here.

<div id="app">
  <h2>Each text field should have its own state and clicking the clear button should only clear that specific field</h2>
  <ul v-for="todo in todos">
    <li>
      <input type="text" :placeholder="`${todo.text}`">
    </li>
    <li>
      <input type="text" :placeholder="`${todo.text1}`">
    </li>
    <button>Clear</button>
  </ul>

new Vue({
  el: "#app",
  data: {
    todos: [
      { text: "Learn JavaScript", text1:"Hey" },
      { text: "Learn Vue", text1:"Hello"  },
      { text: "Play around in JSFiddle", text1:"Ciao"  },
      { text: "Build something awesome", text1:"Something"}
    ]
  }
})

If you need to reset specific fields, you can create a method called clear. Before implementing this method, make sure to include value and value1 properties for each item in the todo array and bind them to the respective fields as shown below:

new Vue({
  el: "#app",
  data: {
    todos: [{
        text: "Learn JavaScript",
        text1: "Hey",
        value1:'',
        value:''
          
      },
      {
        text: "Learn Vue",
        text1: "Hello",
        value1:'',
        value:''
      },
      {
        text: "Play around in JSFiddle",
        text1: "Ciao",
        value1:'',
        value:''
      },
      {
        text: "Build something awesome",
        text1: "Something",
        value1:'',
        value:''
      }
    ]
  },
  methods:{
       clear(i){
       this.todos[i].value='';
        this.todos[i].value1='';
       }
  }
})

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<div id="app">
  <h2>Each text with it's own state and clear should reset the respective text fields</h2>
  <ul v-for="(todo,i) in todos">
    <li>
      <input type="text" :placeholder="`${todo.text}`" v-model="todo.value">
    </li>
    <li>
      <input type="text" :placeholder="`${todo.text1}`"  v-model="todo.value1">
    </li>
    <button @click="clear(i)">Clear</button>
  </ul>
</div>

It is highly recommended to review the documentation available at https://v2.vuejs.org/v2/

In order to achieve your goal, you need to include several basic constructors that are currently missing. First and foremost, add the click event to the button. (https://v2.vuejs.org/v2/guide/events.html)

Additionally, make sure to reference the index of the todos while rendering them (https://v2.vuejs.org/v2/guide/list.html)

Following these steps, create a straightforward method named clear:

new Vue({
  el: "#app",
  data: {
    todos: [
      { text: "Learn JavaScript", text1:"Hey" },
      { text: "Learn Vue", text1:"Hello"  },
      { text: "Play around in JSFiddle", text1:"Ciao"  },
      { text: "Build something awesome", text1:"Something"}
    ]
  },
  methods: {
    clear (index) {
      // Allows for unlimited keys
      for (let key in this.todos[index]) {
        this.$set(this.todos[index], key, null);
      }
    }
  }
})

Note that within the clear method, reactivity is ensured by utilizing the $set method (https://v2.vuejs.org/v2/api/#vm-set) and referencing the corresponding index.

Lastly, the inputs value is bound to the todo model using Vue's v-model. Do I earn extra credit for this? (https://v2.vuejs.org/v2/api/#v-model)
