Stepping Through a Script

Use the script debugger toolbar to step through your script. To use the toolbar, you must have already launched a script debugging session and triggered the script through your browser.

The toolbar has the following buttons:

Button	Description
	Remove All Terminated Launches - clears the Debug window of any failed or terminated debug session launches.
	Resume - resumes running the script from the current breakpoint.
	Suspend - suspends the script.
	Terminate - terminates the debugging session.
	Disconnect - disconnects the debugging session.
	Step Into - steps into the script at the current breakpoint.
	Step Over - steps over the current breakpoint.
	Step Return - to return from a method which was stepped into.
	Drop to Frame - Not used in the Script Debugger.
	Use Step Filters - Not used in the Script Debugger.

When a script hits a breakpoint, the script execution is suspended and doesn't resume until you direct it to do so. In the Debug Perspective, a Script Thread node appears under the session node. The Script Thread contains a stack frame representing the execution path. The following image depicts a halted Script Thread and stack frame:

To resume the halted script, click the Resume button or use one of the stepping commands to continue the script execution.
