Example text

Length; Now we have two arrays for each product group populated with the data for all of the products within those groups. We also have four variables that contain the lengths of each of the arrays. With this done, it's time to move on to the next step—creating the function that will populate our second pull-down menu. Creating the Drill-Down Menu Function Before we begin writing the function, we need to find a value inside the function. When the user selects a product group from the first menu, the script will have to clear out any values that are currently occupying the second menu before it inserts the new products.

If it was, we won't want to repopulate the menu, so we will use an if statement to make sure that choice is greater than 0. selected=true; } else if (choice == 1) { OutputListSize = group1_length; arrayName = "group1"; } else if (choice == 2) { OutputListSize = group2_length; arrayName = "group2"; } else if (choice == 3) { OutputListSize = group3_length; arrayName = "group3"; } else if (choice == 4) { OutputListSize = group4_length; arrayName = "group4">; } var currentPosition = 0; } if (choice > 0) { … } Now that we know that a new product group has actually been chosen, we can start repopulating the second menu.

This way, the user will always be able to tell which category he or she is in. To accomplish this we won't have to change our script; we simply take out the event handlers from that graphic's tag and change the image called in the tag to the On version. The other change we need to make is a little bit more complicated and requires us to modify the functions that we wrote for the homepage. What we want to do is to turn off the graphic for the category that we are in when we roll over any of the other navigation images.
