[Seaside] Jump somewhere after rendering
sangria at gmx.net
Tue Jun 7 12:24:59 CEST 2005
I haven't got my image around at the moment. But I can
give you some hints.
You need to create two methods. One to create a possible
jump destination and one for the actual jump.
"Create a possible target. <a name=aSymbol></a>"
self attributes at: 'name' put: aSymbol.
self tag: 'a'.
self script: 'document.location.hash = ', aSymbol.
Now lets assume you have a parent component named
WAParent that contains several child components
The renderContentOn: methods need to look something
... render all children ...
html jump: aSymbol
html marker: aSymbol
... render the child component ...
There is still some code missing.
Every WAChild component needs to have a unique
identifier for the "html marker: aSymbol" call and
the WAParent component needs to know the jump
destination for the "html jump: aSymbol" call.
Does that help?
