The task is to delete the item from the list when the button is clicked. This all should be done by using ng-click. This is done by using the splice() method. The syntax for the method is given below.
Syntax for splice() function:
array.splice(indexno, noofitems(n), item-1, item-2, ..., item-n)
Example for splice() function:
The keywords in syntax are explained here:
- indexno: This is required quantity. Definition is integer that specifies at what position to add/remove items.
If it is negative means to specify the position from the end of the array.
- noofitems(n): This is optional quantity. This indicates a number of items to be removed. If it is set to 0, no items will be removed.
- item-1, …item-n:This is also optional quantity. This indicates new item(s) to be added to the array
Example: Let us focus on example more. Here we will try to prove the delete operation via example. Here student names are given who have an account on GeeksForGeeks. We will try to delete one of the names from the array of student_names.
