FYI: Creating circular references is a perfectly OK thing to do.

Oh, yes, you're right. Now that you say it, I remember having read this before. Thanks! And that comes from the biggest software company in the world... :-( -- Jorge.

What is an "innerHTML bug"? The - innerHTML - property is a Microsoft invention, and has not yet become subject to any formal standard (proposals don't count in this regard), so there are very good grounds for asserting that whatever IE does is 'correct' (because they define their own invention), and whenever anyone else differs then they are the ones with the 'bug'.

I see, it's my fault to expect it to work with <table>s and <otherArbitrarilyChosenElement>s (*) (in IE, innerHTML is *read*only* for these... ROTFLOL: "unknown runtime error"). The reason being that Microsoft brilliantly rounded their own invention to full perfection by adding the clause "you can use it freely, well, not really" in the definition, right ? Thanks, but I prefer much more the innerHTML that works r/w for any kind of element, the one that comes with every browser except IE. (*)table, select, pre, thead, tfoot, tbody, tr, and in some circumstances, even a <div> ! -- Jorge.

It is propaganda. While IE is not the best browser which has been made, your objections are demagogy. What exactly is the problem that you can not write applications without circular reference pattern? How many time circular reference pattern is the best design which you can choice? If you do not want to care about circular reference pattern - just do not created in first place. |
