To Enter the coupon() Function
The fourth user-defined function added to the Gift Shop Web page is the coupon() function, which opens
the coupon pop-up window when the user clicks the floating image. Table 11-16 shows the code for the coupon()
function.

Line 39 declares the function. Line 40 uses the open() method to open the Coupon Web page as a pop-up
window. The attributes settings size the window to a width of 525 pixels and a height of 360 pixels. This window
does not need any menu or scroll bars. Line 41 closes the function.
