Removing an element from an array specifying a value in Javascript

Question

I have read this question:

Deleting array elements in JavaScript - delete vs splice

And it appears that both splice and delete require an index of the elemen

Answer 1

You want to use the splice() function to remove the item, indexOf will find it in the array:

To Find a specific element in the Array: (to know which to remove)

var index = array.indexOf('test2'); 

Full Example:

var array = ['test1', 'test2', 'test3'];
var value_to_remove = 'test2';
array.splice(array.indexOf(value_to_remove), 1);
