My question is this
When you click the "Continue Adding" link after 5 items are displayed, click once to add the specified amount of data until the data in the json file is fetched
That is, after 5 items are displayed, click for the first time , displays 6, 7, 8, the second time displays 9, 10, 11, and so on. Is there any way to solve it? My code is as follows:

For the first request, store the returned data in an array. You can just operate this array the next time you click. There is no need to request again
