To delete two elements from an object in Vue.js, you can use the delete keyword in JavaScript.


Assuming you have an object named myObject with the following properties:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
data() {
  return {
    myObject: {
      prop1: 'value1',
      prop2: 'value2',
      prop3: 'value3',
      prop4: 'value4'
    },
  }
}


If you want to delete two properties, let's say prop1 and prop3, you can do the following in a method:

1
2
3
4
5
6
methods: {
  deleteProperties() {
    delete this.myObject.prop1;
    delete this.myObject.prop3;
  }
}


Now, calling the deleteProperties() method will delete prop1 and prop3 from myObject.


Alternatively, you can use Vue.delete or this.$delete for reactive deletion. Using these methods ensures that the view updates when the object changes. Here's an example:

1
2
3
4
5
6
methods: {
  deleteProperties() {
    Vue.delete(this.myObject, 'prop1');
    Vue.delete(this.myObject, 'prop3');
  }
}


Make sure to import Vue if you haven't already in your component file.
