问题 If I have a store under ExtJs 4, how do I get an id from a newly added record after a sync occurs? For example, if I have a PersonStore set to autosync and I add a new person based on a form filled out by the users, I can add the new record to the store by doing the following; var values = button.up('form').getForm().getValues(), store = Ext.StoreMgr.lookup('PersonStore'), result; result = store.add(values); Since autosync is set to true, this sends over the new value to the backend where it

问题 I'm trying to fetch a bunch of photo data from Flickr via a jQuery AJAX call using JSONP, but I don't want to use the data right away. Instead, I'd like to preserve it for use later. In a complicated case, I'd like to let users perform different queries on the prefetched data. In a simpler case, I'd like to just load the next n images each time the user clicks a button.
