Direct Known Subclasses:

ERXApplication

public abstract class ERXAjaxApplication
extends com.webobjects.appserver.WOApplication

ERXAjaxApplication is the part of ERXApplication that handles Ajax requests. If you want to use the Ajax framework without using other parts of Project Wonder (i.e. ERXSession or ERXApplication), you should steal all of the code in ERXAjaxSession, ERXAjaxApplication, and ERXAjaxContext.

ERXAjaxApplication は Ajax リクエストをサポートします。

shouldIgnoreResults

public static boolean shouldIgnoreResults(com.webobjects.appserver.WORequest request,
                                          com.webobjects.appserver.WOContext context,
                                          com.webobjects.appserver.WOActionResults results)

takeValuesFromRequest

public void takeValuesFromRequest(com.webobjects.appserver.WORequest request,
                                  com.webobjects.appserver.WOContext context)

Ajax links have a ?_u=xxx&2309482093 in the url which makes it look like a form submission to WebObjects. Therefore takeValues is called on every update even though many many updates aren't submits. This method checks to see if all you have is a _u or _r and an ismap (the #) param for form values. If so, it's not a form submission and takeValues can be skipped.

Overrides:

takeValuesFromRequest in class com.webobjects.appserver.WOApplication

Parameters:

request - the current request

context - the context
