Scripting Example: Client Check on a Mandatory field

You can check mandatory columns before saving. Suppose an inserted person record cannot be saved if the Family Name field has no value. In this case, a message must be shown to prompt the user to enter a Family Name:

1.	From the catalog, open the appropriate page.

2.	For the SaveButton in the BottomButtonGroup:

·	Delete the existing commit action.

·	For the onclick event listener, insert a callClientScript action.

3.	For the callClientScript action, set the Script property to:

if ( getValue("PERSON","FAMILY_NAME") == "" )

alert(Please enter a value for Family Name.)

else

commit()

NOTE:

The getValue JavaScript method is defined in the <publication folder>/js/interface.js file.

4.	Save your changes, and publish your application.

In the corresponding web page, a message pops up if the user does not enter a value for Family Name, and clicks Save.
