If jQuery traps and ignores the error, how would you diagnose the problem?

why should i try to do this?

I need to set a value, and when a browser can not understand it, it should not stop the script.. its also possible to make a console log message in the catch block with key and value - when you need to debug it.

But jquery should not break the execution.

In this special case its fact: I want to set this on every browser who understand the css value display=table and when IE cannot handle it - it is ok with the default value for display.

That patch would silently accept any invalid string, number, or object for a css value. Would you really want that?

yes, shure. I think this patch in combination with a jQuery.log() in the catch block is a very good solution. like this...

try {style[ name ] = value;} catch(e) {jQuery.log('invalid style: ' + name + '=' + value);} 

There aren't any other places in jQuery that use

console.debug

and this doesn't seem like the right place to start. I'll close this for now. There are other tickets and threads open that suggest a more complete "debugging" version of jQuery and it seems that something like this belongs there.
