If you also want to debug scripts in other contexts (. There are three main components in this demo project:ĭebuggerPanelsTabControl - it contains all Debugger user control widgets such as Output, Break points Locals, Watches and Stack FramesĭebugCodeEditContainer/DebuggerUIController- these classes are responsible for displaying relevant script code during debugging (as an example, when script execution stops in the source code, DebuggerUIController focuses relevant page containing Code Editor which displays script content, or opens new page if script file was not yet opened)ĭebugMenu/DebuggerControlToolbar - provide set of debug menus and toolbars for debug commands such as Start, Stop, Break, Step Into and Step Over. Script debugging in IE needs be enabled, which requires us to disable the first option out of the three. So we have decided to come up with simplified quick start project, which demonstrates how debugging logic is glued together. These components are used in our AlterNET Studio demo project, however that demo source code also includes lots of code related to file/project management, form designing, etc., which may create difficulty to understand how it all works. Select one of the debugging commands to either run or to single-step through the program. In addition to the Script Debugger itself we provide set of debugger UI widgets, available both for WinForms and WPF platforms, which include Breakpoint, Stack Frame, Output, Locals, Watches and Threads User controls, as well as Debugger Toolbar and Menus. You can debug the code in the currently active document window. NET Framework debugging API for debugging C#/Visual Basic, Google Chrome Debugger development tools TypeScript/JavaScript and Microsoft Script Hosting for IronPython. However, before we go into debugging techniques and the various debugging tools, let’s understand what bugs are. JavaScript has different debugging techniques and tools to increase your code’s efficiency. Our three Script Debugging engines for C#/Visual Basic, TypeScript/JavaScript and IronPython implement this base interface using different set of tools -. It is a problem-solving skill, whereby existing bugs are identified and resolved to enhance efficient running of codes or programs. The debugger in JavaScript stops the execution of the code and calls the debugging function. The JavaScript Debugger is the primary strategy for debugging Business Rules and other synchronous server-side scripts. JavaScript debugger keyword is something that we can put in any script we write. Script debugger itself is a non-visual component that provides basic debugging functionality via IScriptDebuggerBase interface, such as Start/Stop/Break/Step Into/Step Over commands, list of Breakpoints, and events that are triggered during debugging, for example when Execution stops or debugger state changes, or stack frame switched. Use the IE Developer Tools Script debugger to set breakpoints in your code and then examine the data, as well as the Call Stack and Watch expressions in the. With this JavaScript debugger, we can set breakpoints too and get to know the root cause of the error while the code is executing.
