Tracking data

The Data Browser tab is your window into the JavaScript engine. It displays all live data defined in the current
context, as a list of variables with their current values. If execution has stopped at a breakpoint, it shows
variables that have been defined using var in the current function, and the function arguments. To show
variables defined in the global or calling scope, use the Call Stack to change the context (see "The call stack").
You can use the Data Browser to examine and set variable values.
Click a variable name to show its current value in the edit field at the top of the tab.

To change the value, enter a new value and press enter. If a variable is read-only, the edit field is disabled.

The flyout menu for this tab lets you control the amount of data displayed:
Show Global Functions toggles the display of all global function definitions.
l
Show Object Methods toggles the display of all functions that are attached to objects. Most often, the

interesting data in an object are its callable methods.
Show JavaScript Language Elements toggles the display of all data that is part of the JavaScript language

standard, such as the Array constructor or the Math object. An interesting property is the _ _ proto _ _
property, which reveals the JavaScript object prototype chain.
Each variable has a small icon that indicates the data type. An invalid object is a reference to an object that
has been deleted. If a variable is undefined, it does not have an icon.

You can inspect an object's content by clicking its icon. The list expands to show the object's properties (and
methods, if Show Object Methods is enabled); the triangle points down to indicate that the object is open.
Note: In Photoshop® CS2, the Data Browser pane is populated only during the debugging of a JavaScript
program within Photoshop.
