JavaScript array remove

     

In JavaScript array there is not any in-built method that will remove the specified element according to the user's choice. So we can use the pop() method to remove the element of the array. We can create different methods that will remove the specified element by using the pop() method. Here in the following example we have created a simple remove() method that will remove an array element from the back end side.

In following example code we have created the function remove() which accepts the Array Object name and performs the pop()  operation on the passed array object.

function remove(arrayName)
{
  arrayName.pop();
  document.writeln("==>Removed one element
    by the end of Array</br>");
}

Here is the sample code of JavaScript array remove example as follows:

javascript_array_remove.html

<html>
<head>
<title>

<script type="text/javascript">
var arr = new Array(5);
arr[0]="Rose";
arr[1]="India";
arr[2]="Technologies";
arr[3]="Pvt";
arr[4]="Ltd";
function remove(arrayName)
{
arrayName.pop();
document.writeln("==>Removed one element by the end of Array</br>");
}
document.writeln("Array before calling remove() method is =<b>"+arr+"</b></br>");
remove(arr);
document.writeln("Array after calling remove() method is =<b>"+arr+"</b></br>");
</script>
</head>
<body bgcolor="#ddcdff">
<h2>

</h2>
</body>
</html>

Output of the example will look like as shown below :
