JS equivalent for jQuery one()

Question

Can someone point me towards a solution for the following? I\'m trying to find a JS equivalent for this jQuery code:

var formSelector = \'my selector here\';

Try to write your implementation of one. Like this:

function one(element,eventType,callback,self) {
    var one=function(event) {
        try{
            callback.call(self,event);
        } finally {
            element.removeEventListener(eventType,one);
        }
    }
    element.addEventListener(eventType,one);    
}
