This question already has an answer here: How to append something to an array? 25 answers You can use the push method. For instance (using Firebug to test quickly) : First, declare an array that contains a couple of items : >>> var a = [10, 20, 30, 'glop']; The array contains : >>> a [10, 20, 30, "glop"] And now, push a new value to its end : >>> a.push('t

This question already has an answer here: How to append something to an array? 25 answers You don't need jQuery for that. Use regular javascript var arr = new Array(); // or var arr = []; arr.push('value1'); arr.push('value2'); Note: In javascript, you can also use Objects as Arrays, but still have access to the Array prototypes. This makes the object behave like an array: var obj =
