debug JavaScript on IE6

The built-in JavaScript debugger

While developing your next site, you’ve may noticed that under IE, specially version 6, it’s very hard to debug any kind of JavaScript code. Yes actually if you’ve configured the browser for that purpose you may get any message, which unfortunately is completely useless. In general the message is something like: “There’s an script error on some line of the code!”, but very often there’s no such line of code or it’s empty or something else. Actually that poor debugger is giving the error by the generated script code which really does not help.

Microsoft Script Debugger

The installation of Microsoft Script Debugger solves this problem. It gives the line and the code, even highlights the error.

flash player with debugger issue

featured, flex 3, web development, , , , ,

Sometimes Flash Player with debugger is no displaying all correctly. I have an application which displays more than 200 bitmaps on the stage. Because of the Flash Player with debugger helping my Flex Builder 3 installation to work/debug properly the application always loaded correctly those bitmaps, but after been reported by several places that the bitmaps were not loading at all I faced the two-day sprint of finding the issue.

Finally I noticed that the issue does not exists for machines with installed Flash Player with debugger. After uninstalling the software from my machine I start having the problem there.

That case showed us that the ‘debugger’ version was ‘suppressing’ the problems sometimes. In our case it was an incorrect class instance.
