Bug 27400 – Inspector: Automatically Refresh DOM Storage Grids on "storage" event

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Joseph Pecoraro]

It is too much work to click that small Refresh button to view changes in the dataGrid.  The inspected window fires a storage event that can be hooked into to automatically update the data grid.

NOTE: I could totally see this as being a "setting".  If lots of storage events are firing and the table keeps updating it might not be good for a developer to work with.  It may be a good idea to add a permanent setting, and toolbar item, that will allow the user to activate "live updates" or not!

Live Update both DOM Storage Grids

NOTES:

- Assumes only 2 storages exist (like the current code does with the "isLocalStorage" property.
- Tested on localStorage and sessionStorage and it worked great.
- register/unregister functions would be great to use for a toolbar item in case this moves into a setting.

You should add your name and copyright on a new line instead.

You should use double quotes for strings.

An early return would be better here.

Triple equals.

Ditto.

Done. Renamed flag to "isLocalStorage" like the inspect() patch coming for Keishi.

Instead of a setting, another option is to add a timer before doing the update. Both options are valid.
