"Display" Frame

JavaScript just grabbed the keyword from the data frame above and, using the document.write() call, wrote it to the document. The keyword from the data frame above is:

Since there is a document.write() call involved in this display frame, you must not start loading the display frame until the data frame is completely loaded.

So the frameset loads up a dummy page (blank.htm) just as a placeholder until the data frame is loaded. When the data frame is loaded, it calls the parent.frame_loaded() function which in turn begins the loading of this display page.

NOTE: The order of events is very important. The data frame must be loaded before the display frame starts its loading.
