Description
Initiates when a form submits data to the
host through the HTTP protocol. At this point, the data is organized
into a data set but has not been sent to the host. Calculations
and scripts associated with this event can examine and alter the data
prior to the form submission. If the calculation or script is set
to run on the server, the form sends the data to the server indicating
that it should run the calculation or script before performing any
additional processing.
Note:
This event does not
distinguish between submissions initiated by instances of clicking
buttons or to different URLs. Any script that needs to make these
distinctions must include code to determine which button was clicked.
In general, the
preSubmit
event is conceptually
similar to the
preSave
event and serves a similar
purpose.

Example
You
can use this event to change form data immediately before the data
is submitted. For example, you can create a script on the
preSubmit
event
to scan the amount of data and display a message to the form filler
estimating how long the data submission may take.
