Supposing you have the aforementioned element stored in the - elm -
variable, and the classes' array in the - classesArr - variable:
var classNamesRegex = new RegExp('\\b(' + classesArr.join('|') + ')\\b'); //
Generates /\b(foo|bar|foob)\b/
if(!classNamesRegex.test(elm.className)){
window.alert('get me out of here');
}
