If you do not specify any elements, splice() will only remove elements from the array. The elements to add to the array, beginning from start. In this case, you should specify at least one new element (see below). If deleteCount is 0 or negative, no elements are removed. However, if you wish to pass any itemN parameter, you should pass Infinity as deleteCount to delete all elements after start, because an explicit undefined gets converted to 0. 2.) The starting and ending index of the split are the same. So the minimum value of the pagenumber attr should be 1, never anything less unless you handle that case in the function. If deleteCount is omitted, or if its value is greater than or equal to the number of elements after the position specified by start, then all the elements from start to the end of the array will be deleted. 1.) If the pagenumber is 0 then it will try and set the starting split at -1 pagesize which returns an empty array. Negative index counts back from the end of the array - if start = array.length, no element will be deleted, but the method will behave as an adding function, adding as many elements as provided.Īn integer indicating the number of elements in the array to remove from start.Zero-based index at which to start changing the array, converted to an integer.
