11/20/2022 0 Comments Javascript splice![]() ![]() This is how we can replace elements from any position by new elements. The last two elements JavaScript and HTML are replaced by VBScript and Perl. Var t1=scripts.splice(2,2,"VBScript","Perl") īy using the above code you can see the last two elements of the scripts array is replaced with two new elements. Replacing elements of an array using splice methodĭocument.write("-Now after applying splice()-") We will take our scripts array example, here is our array. Now let us try to understand how splice method works in different conditions. All the elements removed from scripts array will be placed in a new array t1. The replaced list can be more than the number of items to be removed. List1 is the name of the element to be replaced. Length is the number of elements to be removed starting from the starting_number, If it is 0 then nothing is removed. Starting_number is the array element number (index ) from where the starting element is to be taken up,Note that the first element index is 0 Var t1=scripts.splice(starting_number,lenght,"list1") scripts is our array object, Here is the general syntax of splice method when applied to our scripts array object ( this is the example of array we are using in all our previous array tutorials). This is a method by which we can replace elements of an array with a new set of elements. ![]() We can add new element, we can remove some element, we can create new array by using (or taking) elements from an array. Splice() is a powerful method in JavaScript array handling and it almost gives all type of element handling inside an array.
