This too is very sad that this isn’t part of the DOM core functionality. But hey, it makes for fun references like this! This function however isn’t quite a function; it’s a prototype that extends the DOM Array object. I remember one day thinking to myself “surely I can do this in PHP, it’s gotta be in JavaScript.” Well, this extension makes it work just like you’d expect if you’re a PHP developer. Here is a version from EmbiMEDIA
inArray Prototype Array object by EmbiMedia
Array.prototype.inArray = function (value) {
var i;
for (i=0; i < this.length; i++) {
if (this[i] === value) {
return true;
}
}
return false;
