Browser Link JavaScript breaks on debugging WebForms project - Expected Identifier

Question

Upon debugging an ASP.NET WebForms project, I'm shown an error dialog in Visual Studio 2013.

The Browser Link feature includes a handful of pre-generated or runtime-generated JavaScript.

JavaScript critical error at line xyz column abc in http://local.host/foo/browserLink\n\nSCRIPT1010:

Expected Identifier

This is on setting the line label.for = id;

How can I avoid this error?

• Visual Studio 2013 Ultimate
• IE 11
• Windows 8.1 Pro

Answer 1

You'll find the problem is the new Browser link feature.

You can disable it, it solved my issue with IE7 and below when debugging.

Answer 2

for is a reserved word. You either have to choose another name or do label["for"] = id;

IE doesn't accept reserved javascript words.
