Hi everyone.
I am wondering if there is some way to call the getElementById on a
website
through Cocoa, and then return the value of the field. I am
assuming it
would somehow be through WebKit, but I am not sure how to do this
(as well
as if the method needs a different way to get the page's code). The
use
would be the application getting the value of a hidden field, and then
outputting it to the user.
Sincerely,
Pierce Freeman
You can do this either by using the Cocoa DOM API directly:
You call -mainFrameDocument on your WebView to get a DOMDocument
instance, and have access to the DOM functions from here (there is no
up-to-date doc of the Cocoa DOM API, you will have to check headers
files directly to see what function is available, for example the
DOMDocument.h file show you that there is a -[DomDocument
getElementById:] method.
or you can execute js from your Cocoa code:
