Hi Sören,
What you need to do is this:
- when including exhibit-api.js, add ?autoCreate=false to the end of the
URL.
- add an onload handler to <body>.
- in that onload handler, you want to do something like the code here
http://static.simile.mit.edu/exhibit/api-2.0/scripts/create.js
but you also want to do your auto configuration before
window.exhibit = Exhibit.create();
The database object has a few methods for inspecting the properties.
var propertyIDs = window.database.getAllProperties();
for (var i = 0; i < propertyIDs.length; i++) {
var propertyID = propertyIDs[i];
var property = window.database.getProperty(propertyID);
switch (property.getValueType()) {
case "number": ...
case "date": ...
...
}
}
The database is implemented here:
http://static.simile.mit.edu/exhibit/api-2.0/scripts/data/database.js
Hope that helps,
David
