Dynamically updated drop down
box This example shows how to dynamically update drop down boxes with a little twist. The data about the makes and models of cars for a particular year is stored in a 3-dimensional array. If this page were dynamically generated, this array could be generated on the fly from the data in the database. NOTE: In some versions
of Netscape browsers, the size of the combo box will not change dynamically
to accommodate for the larger or smaller size of options. That is the
box will not become wider if options require more space. IE automatically
updates the size of the component.With
Netscape there are two options. First is to find the width of the longest
option and to put extra spaces into the text of the initial option,
so that it will take as much space as the largest option. This way,
we will be guaranteed that the largest option will still have enough
space. Second option is to include an update statement "history.go(0)",
which will reload the page and re-size the component. |
