javascript: Remove items from an array
February 22nd, 2010 by jeremychoneFrom John Resig Javascript array remove
Array.prototype.remove = function(from, to) {
var rest = this.slice((to || from) + 1 || this.length);
this.length = from < 0 ? this.length + from : from;
return this.push.apply(this, rest);
};
Examples:
// Remove the second item from the array array.remove(1); // Remove the second-to-last item from the array array.remove(-2); // Remove the second and third items from the array array.remove(1,2); // Remove the last and second-to-last items from the array array.remove(-2,-1);
