We adapted some cross-site scripting style strategies in order to achieve a tight coordination between Jetpack and the code in the slidebar; therefore we use a hidden iframe (fed with data URIs) to communicate from the slidebat to jetpack (which listens for the load event), while from jetpack to slidebar or to any tab we inject script tags with raw code or JSONP. | We adapted some cross-site scripting style strategies in order to achieve a tight coordination between Jetpack and the code in the slidebar; therefore we use a hidden iframe (fed with data URIs) to communicate from the slidebat to jetpack (which listens for the load event), while from jetpack to slidebar or to any tab we inject script tags with raw code or JSONP. | ||
We use the Jetpack storage in a particular way: we store a large part of the slidebar's DOM tree into the store instead of individual objects. The concept is that the slidebar it is not a mere View (as in MVC) of a Model, but the Model itself, directly manipulable. If someone drags and reorder some actions (DOM elements) there is no need for propagating those changes to an underlying granular database, no need to determine which individual records have to be updated in a consistent manner.
