Chapter 27 Building Dynamic Pages
For an example even nonprogrammers can try, see “Customizing Default Actions”
on page 559.
1. In Page view, select the object whose parameter values you want to script, and
add any actions you want to use as components of the JavaScript expression.
For these actions, ignore the When field, since each action is triggered by the
expression. Also, if an action’s only purpose is to be called by the expression,
disable the action by clearing the check box next to it on the Actions tab of the
Properties panel.
2. Create the action whose parameter value you want generated by the expression,
as described in “Adding Actions to Objects and Pages” on page 535. Or, open
an existing action by double-clicking it on the Actions tab of the Properties
panel.
3. In the Set Action dialog, open the Parameters menu and choose Expression.
The JavaScript Expression dialog appears. If the action already has default
parameter values, the dialog displays the code for those values.
4. Enter your own JavaScript to generate the parameter value, or modify the code
that’s already there. NetObjects Fusion doesn’t verify code you enter, so be sure
to use valid syntax.
Enter a JavaScript expression here,
replacing or modifying existing code
Opens a list of actions you can call
from the expression
To build your expression around existing actions, click the Insert Action button,
select an action from the Actions dialog, and click OK. NetObjects Fusion
inserts the action at the insertion point, in the form $(ActionName).
5. Click OK in the JavaScript Expression dialog and again in the Set Action
dialog.
When the action is triggered, it uses the parameter values generated by your
expression.
