Este artigo é uma demonstração rápida das secções principais da interface do utilizador do 'Depurador de JavaScript'. A IU está dividida verticalmente em 3 painéis:
The source list pane lists all the JavaScript source files loaded into the page, and enables you to select one to debug. At the top level sources are organized by origin, and under that they're organized by the directory structure from which they are served.
You can search for a file using Ctrl + P (Cmd + P on a Mac).
This shows the JavaScript file currently loaded.
When the source pane is focused you can search for a string in the file using Ctrl + F (Cmd + F on a Mac).
Breakpoints have a blue arrow overlaid on the line number. Conditional breakpoints have an orange arrow. If you're stopped at a breakpoint, the entire line gets a green overlay. In the screenshot below there are three breakpoints:
No topo do painel à direita, existe uma barra de ferramentas:
A barra de ferramentas consiste em:
Under the toolbar, you'll see all the breakpoints you've set. Next to each breakpoint is a checkbox which you can use to enable/disable it:
When the debugger's paused, you'll see a call stack:
Each level of the call stack gets a line, with the name of the function and the filename and line number. Clicking the line opens that source in the source pane.
In the right-hand pane you'll see a label "Scopes" with a disclosure arrow next to it. When the debugger's paused, you'll be able to expand this section to see all objects that are in scope at this point in the program:
Objects are organized by scope: the most local appears first, and the global scope (Window, in the case of page scripts) appears last.
