Javascript removing and rearranging array elements

Question

I have this collection of images resources where that is stored in array, the user will select an image and then the selected image will be removed from the list(also from the array) and after that The array would be rearrange. How could I perform such task? (as much as possible I do not want to use an open source library)

Answer 1

Sounds like you need to look up splice() method. It allows you to add and remove one to many items within an array at any index.

here's reference for it. https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/splice

Answer 2

your question lacks a code example but you can use Array.splice(index,number) whereas index is zero based and number is how many items to remove.

images.splice(selectedIndex,1);
