function removeClass(elements, myClass) { | |
// if there are no elements, we're done | |
if (!elements) { return; } | |
// if we have a selector, get the chosen elements | |
if (typeof(elements) === 'string') { | |
elements = document.querySelectorAll(elements); | |
} | |
// if we have a single DOM element, make it an array to simplify behavior | |
else if (elements.tagName) { elements=[elements]; } | |
// create pattern to find class name | |
var reg = new RegExp('(^| )'+myClass+'($| )','g'); | |
// remove class from all chosen elements | |
for (var i=0; i<elements.length; i++) { | |
elements[i].className = elements[i].className.replace(reg,' '); | |
