display Parcel Data ASP., which returns the appropriate map feature.

Page 123 highlights

The tag holds two JavaScript functions: getMap and runReport, which displays our Autodesk MapGuide report. The runReport function consists of two statements. The first statement writes a line of text to the right-hand frame of our report application, instructing users to select one or more map features. This instruction displays each time runReport is invoked, regardless of whether the user has selected features. If features are selected, the instructions are replaced in the frame by the contents of the newly generated report; otherwise, the instructions remain in the frame to provide feedback. Note parent refers to the top-level frame and Right is the name we specified for our right-hand frame in parcel_frames.htm. Refer to a third-party JavaScript manual for more information on writing to frames and windows. The second statement uses the viewReport method to run our report and begins by calling getMap, which returns the appropriate map feature. That feature is then passed to viewReport, which directs Autodesk MapGuide to display Parcel Data (ASP). Now that our function is defined, to call it we'll add a element to parcel_map.htm:

Creating Report Scripts with ASP
|
123
The
<SCRIPT>
tag holds two JavaScript functions:
getMap and runReport
,
which displays our Autodesk MapGuide report. The
runReport
function
consists of two statements. The first statement writes a line of text to the
right-hand frame of our report application, instructing users to select one or
more map features. This instruction displays each time
runReport
is
invoked, regardless of whether the user has selected features. If features are
selected, the instructions are replaced in the frame by the contents of the
newly generated report; otherwise, the instructions remain in the frame to
provide feedback.
Note
parent
refers to the top-level frame and
Right
is the name we specified
for our right-hand frame in
parcel_frames.htm
. Refer to a third-party JavaScript
manual for more information on writing to frames and windows.
The second statement uses the
viewReport
method to run our report and
begins by calling
getMap
, which returns the appropriate map feature. That
feature is then passed to
viewReport
, which directs Autodesk MapGuide to
display Parcel Data (ASP).
Now that our function is defined, to call it we
ll add a
<FORM>
element to
parcel_map.htm
:
<FORM>
<INPUT TYPE="button" VALUE="Parcel Report" ONCLICK=
"
runReport()
"
</INPUT>
</FORM>
This is a standard HTML form consisting of a single button named Parcel
Report. By setting the value of
ONCLICK
to
runReport
, we specify that the
function should be invoked each time a user clicks the button.
Note
A JavaScript function must appear above the JavaScript code that calls it.
This keeps users from trying to call a function before it has been parsed by the
browser. JavaScript functions are typically defined in a single
<SCRIPT
> tag in
the
<HEAD>
section of the HTML file.
