This article is about how JavaScript gets stack trace information for functions. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Get the stack trace information for a function

Using the JavaScript framework, you introduce a lot of code.

Create a view and trigger an event. * you want to know the process of calling a function.

Because JavaScript is not a very structured language, it is sometimes difficult to know when and what happened. Using console.trace (just tracking in the console) makes it easy to debug JavaScript.

Imagine looking at the entire stack trace information for the car instance call function funcZ on line 24:

Var car; var func1 = function () {func2 ();} var func2 = function () {func4 ();} var func3 = function () {} var func4 = function () {car = new Car (); car.funcX ();} var Car = function () {this.brand = 'volvo'; this.color =' red'; this.funcX = function () {this.funcY () } this.funcY = function () {this.funcZ ();} this.funcZ = function () {console.trace ('trace car')}} func1 ()

Line 24 will output:

You can see that func1 calls func2 and func2 calls func4. Func4 creates an instance of Car, then calls the function car.funcX, and so on.

Even if you think your code is very well written, this is still useful. If you want to improve your code. Get trace information and all the functions involved, each of which can be clicked, and you can switch back and forth between them. It's like giving you a selection list of call stacks.
