Here you go, just need to join the array and parse the integer out:

var array = ['1', '2', '3', '4'];
var number = parseInt(array.join(''), 10);
alert(number);

Note: The 10 used in the parseInt function above is to specify the radix (also known as the base in mathematical numeral systems). 10 signifies the base used in decimal system.
