Adding an array to another array of the same type in Vue3 using typescript

I am working on a project in Vue 3 with TypeScript where I have an array of objects called Obj1. When I click the "load more" button, it triggers an axios call to the backend service and fetches another array of objects of the same type. My goal is to append these new rows to the existing array, but for some reason, the following code is not working as expected:

this.Array1.push(response.data)

However, if I add one item at a time, the Array1 gets updated successfully:

this.Array1.push(response.data[0])

I am puzzled as to what could be missing here. Any insights?

Answer №1

After reviewing your query and the functioning code provided:

this.Array1.push(response.data.results[0])

It is clear that response.data.results is the array you wish to manipulate. To add the entire array in one go, you can utilize the ES6 spread operator:

this.Array1.push(...response.data.results)

Answer №2

It appears that you are assigning different values here. The response.data.results is an array, whereas the response.data itself contains a JSON data with an array.

To address this issue, consider simplifying your code:

this.Array1 = response.data.results
