HTML and CSS Reference
EXPLANATION ( CONTINUED )
The HTML form starts here. When the submit button is clicked, the onSubmit
event handler will be triggered and call the popUp() function, causing a new pop-
up window to appear containing the information that the user typed into the
form. At this point the program could ask the user if the data is valid and continue
to process the information by sending it to a server. Because the action attribute
for the HTML form hasn't been defined, nothing will happen.
The input types for the form are defined here as two textboxes, one for the user's
name and one for the address.
The submit button is created here. When the user submits the form, the onSubmit
handler on line 4 will be triggered. The action is shown in Figures 13.22 and 13.23.
