Info

if (debugging) alert("Returned from swapImage() with swapStatus=" and include alert()s marking the flow of execution in swapImages(). By examining the content and order of the alert()s as they appear, you are granted a window to the internal state of your script. Because using many alert()s when debugging large or complicated scripts may be impractical (not to mention annoying), output is often sent to another browser window instead. Using this technique, a new window, say, debugWindow, is opened at the beginning of the script, and debugging information is written into the window using syntax like debugWindow.document.write() method. The only potential gotcha is that you need to wait for the window to actually be opened before attempting to write() to it. See Chapter 12 for more information on inter-window communication. Stack Traces Whenever one function calls another, the interpreter must keep track of the calling function so that when the called function returns, it knows where to continue execution. Such records are stored in the call stack, and each entry includes the name of the calling function, the line number of invocation, arguments to the function, and other local variable information. For example, consider this simple code: function a(x) { } document.write(x); function b(x) { } a(x+1); function c(x) { } b(x+1); c(10); At the document.write in a(), the call stack looks something like this: a(12), line 3, local variable information…
(11), line 7, local variable information… c(10), line 11, local variable information… When a() returns, b() will continue executing on line 8, and when it returns, c() will continue executing on line 12. A listing of the call stack is known as a stack trace, and can be useful when debugging. Mozilla provides the stack property of the Error object (discussed in detail in a following section) for just such occasions. We can augment our previous example to output a stack trace in Mozilla: function a(x) { } document.writeln(x); document.writeln("\n----Stack trace below----\n"); document.writeln((new Error).stack); function b(x) { } a(x+1); function c(x) { } b(x+1); c(10); The output is shown in Figure 23-4. The top of the trace shows that the Error() constructor is called. The next line indicates that the function that called the error constructor is a() and its argument was 10. The other data on the line indicates the filename where this function is defined (after the @) as well as the line number (after the colon) the interpreter is currently executing. Successive lines show the calling functions as we‘d expect, and the final line shows that c() was called on line 16 of the currently executing file (the call to c() isn‘t within any function, so the record on the stack doesn‘t list a function name).
