Stupid anchor question
Locked
 
|
Hello,
I want to do this: when clicking on an anchor, something else must be displayed on a new page..just like simple html MyComponent>>renderContentOn: html html anchor callback:[self renderSomethingElseOn:html]; with:'go to somewhere else' MyComponent>>renderSomethingElseOn:html html div with:'this is something else' and I always get this exception Message not understood: #openTag:attributes:closed: I guess the whole idea might be wrong... is it? Thanks! |

Your html argument will be invalid. The easiest way to make your example work is to create a new Component for 'this is something else' called SomethingElseComponent (or something else) the action triggered by the link would then do a #call: on this new component. This temporarily replaces MyComponent with SomethingElseComponent until you send #answer: in SomethingElseComponent.

For small items such as this (or perhaps an error on form validation or
similar, or a toggle) I prefer to use a boolean instvar such as: #initialize boolean _ false. ^super initialize #renderContentOn: html html anchor callback: [boolean _ boolean not]; with: [html text: 'toggle']. boolean ifTrue: [html div with: [html text: 'this is some text']] Regards, John. www.pinesoft.co.uk Philippe Marschall wrote: > 2007/8/14, Leandro Pérez <[hidden email]>: >> Hello, >> I want to do this: when clicking on an anchor, something else must be >> displayed on a new page..just like simple html >> >> MyComponent>>renderContentOn: html >> html anchor >> callback:[self renderSomethingElseOn:html]; >> with:'go to somewhere else' >> >> MyComponent>>renderSomethingElseOn:html >> html div with:'this is something else' >> >> and I always get this exception >> Message not understood: #openTag:attributes:closed: >> >> I guess the whole idea might be wrong... is it? > > Yes, you mix the callback and the rendering phase.
