Try with this function
function fullScreen() {
fs=window.open('your page','name for window(not needed)','fullscreen=1')
You can complete this function with your preference
remember give a link to close the window
this is the way:
if the link will be placed on the opener window so>>>>fs.close()
or maybe the link will be on the fullscreen window so>>>>>self.close()
NOTE:I'm sorry for my english and this is the right code the other don't
