Why don't you call the next function on the last line of code in the 'current' function?
var myFunctions = {
one: function(){
myFunctions.two();
},
two: function(){
myFunctions.three();
},
three: function(){
myFunctions.four();
},
four: function(){
myFunctions.one();
}
}
$(document).ready(function(){ myFunctions.one(); });
But than ofcourse with eight functions in stead of four.
Good luck!
