Vue Add Object to Specific Position in Array:In Vue, the splice() method can be used to add an object to a specific position in an array. The method takes three arguments: the starting index, the number of elements to remove (which is zero if we only want to add elements), and the new element(s) to add. The starting index indicates where the new element(s) should be inserted, while the second argument specifies the number of elements that should be removed from the array, which in this case is zero since we are only adding elements. The third argument is where the new element(s) are specified, and can be a single object or an array of objects to be added. By using this method, you can easily add new objects to an array at any desired position.
How can an object be added to a specific position in an array using Vue?
This is a Vue application that allows users to add and remove objects from an array displayed in a table. The data
property contains an array of objects (myArray
) and an empty object (newObject
) for storing user input.
The template displays a form for adding new objects with input fields for name and age, and a button to submit the form. The table displays the objects in the array (myArray
) with their corresponding name and age values, as well as a “Remove” button for each row.
The methods
property defines two functions: addNewObject
and removeObject
. The addNewObject
function adds the new object stored in newObject
to the array at a specific position (in this case, index 2) using the splice
method, and then resets newObject
to an empty object. The removeObject
function removes an object from the array at a specified index using the splice
method.

Name:

</label>
<label>
Age:
<input type="number" v-model="newObject.age" />
</label>
<button>Add Object</button>
</form>
