如何通过在其他字段中输入值自动选中复选框？

// HTML
<input type="text" id="inputField">
<input type="checkbox" id="checkboxField">

// JavaScript
const inputField = document.getElementById('inputField');
const checkboxField = document.getElementById('checkboxField');

inputField.addEventListener('input', function() {
  if (inputField.value === 'someValue') {
    checkboxField.checked = true;
  } else {
    checkboxField.checked = false;
  }
});

<!-- HTML -->
<div id="app">
  <input type="text" v-model="inputValue">
  <input type="checkbox" v-model="checkboxValue">
</div>

<!-- JavaScript -->
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script>
  new Vue({
    el: '#app',
    data: {
      inputValue: '',
      checkboxValue: false
    },
    watch: {
      inputValue: function(newValue) {
        if (newValue === 'someValue') {
          this.checkboxValue = true;
        } else {
          this.checkboxValue = false;
        }
      }
    }
  });
</script>
