Throwing errors in Javascript with error object relevancy
error-handling, javascript, throw
Solution
What you are actually looking for is a stack trace for the error. There are no standards for this but most browsers do provide some means of discovery. Doing a quick search comes up with this js stack trace example.
Problem
This is pretty much IE related because IE is the environment I'm using to test this, but I want to know if you can affect the relevancy of the error object properties when you throw an error. Consider the following javascript: ``` function MyClass (Arg1, Arg2) // Line 5 of my.js { if (typeof Arg1 != "string") throw new Error("Invalid argument passed for MyClass"); // Do some other stuff here } ``` Further down your code you have ``` var myvar = new MyClass(100, "Hello"); // Line 3201 of my.js ``` So the above would throw an error, but the error reported in the debugging information would show the error being thrown at line 9 of my.js instead of line 3201. Is this something you can change using standard methods?
