Dynamic Element Specifications

Dynamic elements serve as the basic building blocks of WebObjects applications by linking an application’s scripted or compiled behavior to an HTML page. The linkage can be two-way, in that a dynamic element:

• Initially sets its attributes to values specified by scripted or compiled variables or methods.

• Represents itself as HTML when called upon to do so.

• Synchronizes the values of its attributes to those entered by the user, and passes these values back to your script or compiled code.

With WebObjects, most pages sent to the user’s browser are composed of HTML from a static template combined with HTML that’s dynamically generated by dynamic elements embedded (directly, or in the case of reusable components, indirectly) in that template.

Here are the dynamic elements defined in the WebObjects Framework:

• WOActionURL
