How to remove specific element from JavaScript array?

Firstly find the index of the element you want to remove:

var array = [2, 5, 9];
var index = array.indexOf(5);

1 2	var array = [2, 5, 9]; var index = array.indexOf(5);

Note: browser support for indexOf is limited, it is not supported in IE7-8.

Then remove element using its index and function 'splice':

if (index > -1) {
     array.splice(index, 1);
}

if (index > -1) {

array.splice(index, 1);

}

The second parameter of splice is the number of elements to remove.

Note: splice modifies the array in place and returns a new array containing the elements that have been removed.
