Custom ActionScript functions
Custom ActionScript functions are the equivalent of CFML UDFs. You can define your own functions in ColdFusion
by using the
tag with a
cfformitem
(.as) file. Also, ColdFusion includes a small number of predefined custom ActionScript functions that you can use in
your Flash form controls.
You can use the following custom functions in the ActionScript for all form controls to reset or submit the form:
•
resetForm()
•
submitForm()
You can use the following custom functions in
•
gridName
GridData.insertRow(
•
gridName
GridData.deleteRow(
The following example shows how you can use the two GridData functions to add custom buttons that add and delete
rows from a Flash form. These buttons are equivalent to the buttons that ColdFusion creates if you specify
and
insert="yes"
delete="yes"
placement. This example puts the buttons on the side of the grid, instead of below it and uses longer than standard
button labels.
<cfform format="flash" height="265" width="400">
<cfformitem type="html">
You can edit this grid as follows:
<ul>
<li>To change an item, click the field and type.</li>
<li>To add a row, click the Insert Row button and type in the fields
in the highlighted row.</li>
<li>To delete a row, click anywhere in the row and click the
Delete Row button</li>
</ul>
<p><b>When you are done, click the submit button.</b></p>
</cfformitem>

<cfformgroup type="hbox" style="verticalAlign:bottom;

<!--- To make all elements align properly, all of the hbox children must
be containers, so we must put the cfgrid tag in a vbox tag. --->
