can anyone please point me in the right direction for a json database on the client side for the duration of the pages life.

example:

i have a page with a canvas that i can add elements to and move them around, but i wish to create a Json object so that if an item is added to the canvas, the details are also added or updated in the json. i use asp.net MVC C#.

ideally a good example of add item and edit item and if possible using jquery but any kind of javascript would at least give me a clue.

thanks

    a few clarification points:

    • when you say “for the duration of the pages life”, you mean without any page reloading? if so, then you don’t need storage, just put all relevant data in a variable (such as an array). the JavaScript environment won’t be lost until you reload the page.

    • if it will be client side only, and not stored somewhere else, you don’t need JSON. in fact there’s no such thing as a ‘JSON object’. JSON is a text representation of an object; i.e. a string. What you manipulate in JavaScript are JavaScript objects, which can be represented as JSON on a string, or constructed from a string using JSON format.

    that said, if you want a multi-browser library to store JavaScript object on the client side,persist.js looks interesting. It’s a JS library that shows a common API over several incompatible solutions, including proprietary APIs, cookies and Flash.
