rowpostupdate

note

This article is about the rowpostupdate UDB event handler.

rowpostupdate

The rowpostupdate event may be called from web pages developed in Web Designer and processed by a USoft Page Engine service.

Event	Applies to	Occurs when
rowpostupdate	Data source objects (UdbDataSource)	After a record is updated *

* Whether the value is updated manually or by looking up a (new) value from a dropdown list.

This event is triggered internally by the UdbDataSource class, from the updateMultiple() method of the UdbRecord object that represents the record that was updated. It receives the same options object as rowpreupdate.

How to use

Find or create an Event Listener object with Event Type = rowpostupdate. Event Listeners are in the Web Designer Controls catalog:

Insert the event listener into the data source object. Insert a callClientScript action into the event listener. Use this action's Script property to code the behaviour that you want to see when the event occurs.

You are implicitly associating the event with an event handler function. This function has an options parameter. For available options, see the Options section at the end of this help topic:

function(*event*, *options*){ ... }

Or you can create the event handler more explicitly by calling $.udb('data-source').on().

Options

When the event occurs, the following event handler function is called. You can use this function's options parameter in your event scripting.

function( *event*, *options* )

*event*     ::=  jQuery.Event
*options*   ::=  *event-options*

*event-options*   ::=  {
     values:   *values*,
     record:   *record*,
     hostvars: *hostvars*
}

Event contains the run-time details of the triggered event, of the event type stated above.

This syntax means that you can access the options by scripting:

options.values
options.record
options.hostvars

Values is a Map of the column values that the record was updated with, keyed by column reference.

Record is the UdbRecord object that was updated.

Hostvars is an object with the host variables that were passed along with the update.
