persistence.js add() function not working

问题

I have tried to save an object to database:

Item = persistence.define('Item', {
imageUrl: "TEXT",
})

this is working,the imageUrl is set correctly:

var c = new Item({imageUrl: "a"});

this is not working, imageUrl is empty in the db

var c = new Item();
c.imageUrl = "a";

this is working:

var c = new Item();
c._data.imageUrl = "a";

Seems like a bug.

回答1:

I think I found the reason, If you are using jquery then you have to use: e. g.

obj.name(newValue) 

to set and

obj.name() 

to get attributs.

Can you please tell me where the documentation for such cases can be found? https://groups.google.com/forum/?fromgroups=#!topic/persistencejs/zph_wV1sEic
