DOM Panel

DOM Panel

Inside the DOM Panel you get information about all the different DOM properties and methods. For objects and arrays it offers a expandable tree view. Clicking on them limits the display of the DOM tree to these objects resp. arrays and shows the current element path as breadcrumb list inside the Panel Toolbar. Clicking on a function jumps to it inside the Script Panel. Note, that the panel shows a snapshot of the current state. Changes to properties don't take effect on the display of the DOM panel until you are refreshing it.

Options Menu

This menu is reachable via the little arrow in the panel tab ( ) or by right-clicking on on the panel tab (since Firebug 1.9).

Panel

Values

The display of the different item values is optimized for readability. See the Display of JavaScript values and DOM items.

Color codes

Different color codes let you distinguish between the different types of variables and improve readability. Here they are in detail:

Format	Description
Bold Black	Objects
Black	DOM objects
get in gray	"Getter" functions
Bold green	User functions
Green	DOM functions
Bold Red	Constructor functions

Note that the values of read-only properties are displayed with a pale text color.

Property descriptor info

At the left side of the property value there is a column, which provides info about the different property descriptors within a tooltip.

A lock icon () indicates that a property is neither writable nor has a setter function assigned.

Auto-completion

Like in the Console, CSS and HTML Panel variables are auto-completed while typing. This enhances productivity and supports you making changes.

localStorage

Note that localStorage is just an object so you can create, view, and edit it in the DOM view.

Breakpoint Column

You can add a breakpoint for a property by clicking the Breakpoint Column at the left side of it. By doing this the script execution will be halted as soon as the property is changed. Clicking on a set breakpoint removes it.
