Chapter 14: Error Handling and Debugging When a breakpoint is hit, the next line to execute is highlighted in blue and the call stack and variable panes are filled in with contextual information. Clicking on any of the functions in the call stack immediately takes you to that function in the source code viewer and fills the variable pane with the appropriate local variables. The values of these variables cannot be changed from within Drosera. It ’ s anticipated that the JavaScript debugging features of Drosera will eventually be rolled into the WebKit Web Inspector utility used by both Safari and Chrome. Opera JavaScript Debugger Opera 9.5 ships with web development tools that include a JavaScript debugger. To open the tools, click on the Tools menu and then Advanced Developer Tools. By default, a pane appears at the bottom of the browser as shown in Figure 14 - 29 . Figure 14-29 510
Chapter 14: Error Handling and Debugging By default, the Scripts tab is selected. This tab contains all of the tools for JavaScript development, including the debugger. The first tab within this tab (also called Scripts) contains a list of each JavaScript source on the same page, both inline scripts and included files. Clicking on an item in this list switches you to the Source tab to see the source code (see Figure 14 - 30 ). Figure 14-30 Breakpoints Breakpoints are set on the Source tab by clicking on the line number where you want to set the breakpoint. Unlike other debuggers, you can set breakpoints only on lines rather than on individual statements. Also unlike other debuggers, there is no overall list of breakpoints that you can refer back to. When a breakpoint is hit, a black arrow appears next to the line number of the breakpoint (see Figure 14-31 ). You can see the call stack on the right side of the pane, in the Call Stack tab. The Inspection tab contains information about the variables that are in scope at that point in time. Figure 14-31 511
