Question

add and remove array value in jquery?

I have array of data var y = [1, 2, 3];

I want to remove 2 from array y.

Any one have idea how to remove particular value from array using jquery? I have tried pop() but its working like stack.

Answer 1

You can do something like this:

var y = [1, 2, 3]
var removeItem = 2;

y = jQuery.grep(y, function(value)) {
  return value != removeItem;
});

Result:

[1, 3]

Answer 2

by using simple javascript you can use this:

Array.remove('Valuetoberemoved'); 
ex: y.remove('2');

Answer 3

There is no native way to do this in Javscript. You could use a library or write a small function to do this instead: http://ejohn.org/blog/javascript-array-remove/

Answer 4

With jQuery, you can do a single-line operation like this:

Example: http://jsfiddle.net/HWKQY/

y.splice( $.inArray(removeItem, y), 1 );

Uses the native .splice() and jQuery's $.inArray().
