DataTables Editor - localStorage

This example shows how the ajax initialisation option can be used to replace the default Ajax call that Editor makes and instead use the browser's localStorage abilities to save the state of the table locally on the browser. This means that the user effectively has persistent storage, but it is available only to them on their current browser.

The code in this example shows the ajax option as a function that effectively implements everything that is required by Editor for data storage and retrieval. The 'create', 'edit' and 'remove' actions are each handled by manipulating the JSON data array that is stored in the browser's localStorage.
