PART I. CREATING DYNAMIC HTML.
- Start up Notepad.
- Look at
from class on Monday Sep 25.
- Modify the example so that it uses four different buttons,
labeled "RED", "BLUE", "GREEN" and "YELLOW".
Note that you must give each button a different name as
well as value (i.e., the button label is what is displayed on
- Modify the onclick function call for each button so that when
you click on each button, a window pops up and displays a
message like "you clicked on the RED button" (or something
more creative than that), instead of the message "hello".
Whatever message you use, it must contain text that indicates
which color button you clicked on and the message must be
different for each button!
- Save the file and name it with your last name followed by
the .html extension.
For example, my file would be called sklar.html.
Remember to tell Notepad not to put the "txt" extension after ".html"!
- Try opening the file with a browser and see how it works.
If any of the elements above don't work, go back into the
Notepad window, and edit the file to fix them.
The reload the file in your browser.
Keep doing this until everything works just perfectly :-)
- Open a new file in Notepad.
- Look at the second half of
from class on Monday Sep 25.
- Modify the example so that it uses the image file:
- Replace the href=... sections of each
<area...> tag with onclick=alert('...').
You can fill in the argument to the alert()
function using the text you put in the previous step.
The argument is the text between the single quotes ('),
in the case of ex7.html, the argument is 'hello'.
Note that you will need to update the size of the image in the
<img...> tag and the corresponding coordinates in
each <area...> tag.
Also note that you will need to create a fourth
<area...> tag since there are four colors in the
- When you save this file, name it with your last name, followed by
the number 2, followed by the .html extension.
For example, mine is: sklar2.html.
