![]() ![]() If the variable you are looking at is a string, you can use Watch > Expand all Watches to show you everything in that string on multiple lines. Here you can also use Watch > Save to file and Watch > Load from file to save and load Watch window variables and results. Clicking Watch > Clear Watches will clear all of the variables and results from the Watch Window. The Watch button at the top of the Xbasic Debugger Dialog allows you to manipulate the Watch window in different ways. Alpha Anywhere will evaluate the expression and show the result in the right hand column of the Watch window. To use the Watch window, enter an expression whose value you want to monitor in the left column. The value column will show an error message in red, such as 'variable "txt" not found' if a variable has no clear value. The Watch window has two columns, one to hold variable expressions and a second to display the result of those expressions. The Watch window at the bottom of the screen allows you to examine the contents of variables, fields and object properties. ![]() The currently selected line will be highlighted in blue. The current line indicator icon and the Breakpoint indicator icon will appear in this column. When ignored, a script is obscured in the Call Stack pane, and you never step into the script's functions when you step through your code.The left side of the Module window has a column that is reserved for display of icons indicating which line in the script is currently executing and which lines have breakpoints. Ignore a script to skip it while debugging. To hide such scripts altogether, select Sources > Page > Hide ignore-listed sources. To help you focus only on the code you create, the Sources > Page pane grays out all scripts or directories added to Settings > Ignore List by default. Note: This is a preview feature available from Chrome version 106. In this case, the Call Stack shows the entire call history including async call frames. If supported by the framework you are using, DevTools can trace async operations by linking both parts of the async code together. In the Call Stack section, check or clear the Show ignore-listed frames checkbox and observe the relevant or full list of frames in the call stack.Set a breakpoint at the increment() function.In the Sources panel, open the src > app > file.To view the full call stack including third-party frames, enable Show ignore-listed frames under the Call Stack section. Resume script execution ( F8) to complete this tutorial.īy default, the Call Stack pane shows only the frames that are relevant to your code and omits any scripts added to Settings > Ignore List. Nested functions receive values, not their locations in memory. In JavaScript, changes to arguments are not visible (reflected) outside the function. The Call Stack pane on the screenshot above is outlined in blue. The blue arrow icon represents which function DevTools is currently highlighting. While paused on a line of code, use the Call Stack pane to view the call stack that got you to this point.Ĭlick on an entry to jump to the line of code where that function was called. The Scope pane on the screenshot above is outlined in blue. Non-enumerable properties are greyed out.Double-click a property value to change it.While paused on a line of code, use the Scope pane to view and edit the values of properties and variables in the local, closure, and global scopes. # View and edit local, closure, and global properties In other words, when you see semicolons, you can always expect to step through them even if the actual source you're debugging is minified. When using source maps to debug the minified code in terms of the original code.Therefore, the stepping behavior is identical: The Debugger steps through such expressions just the same. When paused on a line of code containing a function that's not relevant to the problem you're debugging, click Step over to execute the function without stepping into it.įor example, suppose you're debugging the following code: function updateHeader ( ) bar ( ) ![]() Once your code is paused, step through it, one expression at a time, investigating control flow and property values along the way. ![]() While the execution is paused, hover over a class or function name to preview its properties. # Preview class/function properties on hover While the execution is paused, you can also restart the current function and even live-edit it. ![]()
