I have the following situation: the user submits a form, I fetch the data from the server via an Ajax request and displays a chart. However, I want to give the user the option to display the data in the chart in table form or export as csv after he had submitted the form.
I was wondering what’s the best solution to store the data, considering that I don’t want the data to persist if the user opens a new window to submit the form again for example.
The application is in Rails.
Thanks.
You have a few options:
Cookies
LocalStorage
SessionStorage
More info: https://developer.mozilla.org/en/DOM/Storage
Non-standard:
window.name can store anywhere from 1mb up to 10mb depending on the browser. This is more of a hack, but is fairly stable. You would need to implement your own accessor/setter methods on this, where localStorage and sessionStorage have API’s built in.
