Useful functions to enhance productivity!
I was in the midst of writting Prototype's dollar sign function but found this gem:
javascript Code:
function $() {
var elements = new Array();
for (var i = 0; i < arguments.length; i++) {
var element = arguments[i];
if (typeof element == 'string')
element = document.getElementById(element);
if (arguments.length == 1)
return element;
elements.push(element);
}
return elements;
}
// Sample Usage:
var obj1 = document.getElementById('element1');
var obj2 = document.getElementById('element2');
function alertElements() {
var i;
var elements = $('a','b','c',obj1,obj2,'d','e');
for ( i=0;i
