To demonstrate a condition which uses a JavaScript expression, add an additional Number Field
item on Page 1 called
P1_X
. Change the condition in the Show Hide EmpNo Dynamic Action from is not
null to JavaScript Expression. In the Value
text area enter:
this.triggeringElement.value >
$('#P1 X').val()
as shown in Figure 7-18. Refresh the page and enter
20
in the P1_X field. When you
change the department the list of employees will only appear when you select Operations (40) and Sales
(30). You'll notice that if you change the value of P1_X the condition will evaluate accordingly without
having to submit the page or set the value in session state.
