DHTML structure access - square brackets use

[GeorgeH]

Hello.

I have noticed I cannot access object properties by using square bracket notation (javascript) - is there any reason for that? I was unable to find it in AutoIt documentation.

For example:

$oBrowser1.window.frames['gnrl_src'].window.frames['pg_src'].frames['main_src'].name

doesn't work: Error parsing function call.

while "incorrect" (javascript/DHTML) syntax works:

$oBrowser1.window.frames('gnrl_src').window.frames('pg_src').frames('main_src').name

Dot notation works fine too...

$oBrowser1.window.frames.gnrl_src.window.frames.pg_src.frames.main_src.name

Hi and Welcome to the forums!!

I'm afraid I don't really understand your question. This is AutoIt, not Javascript. Square brackets just isn't part of our syntax.

You can 'eval' a quoted string using the Javascript syntax rules, otherwise you must use AutoIt syntax because it is AutoIt that is walking the object hierarchy.

Thanks (not surprisingly I have been lurking around for a while).

Yes, I understand that the AutoIt syntax is different from Javascript.

But since dot notation was usable, and basically most of DOM 'syntax' was also functional (even possible to just copy&paste), I wondered why square brackets do not work - and I haven't found anything in help/wiki. Basically I have discovered that ('xxx') works instead of ['xxx'] only by trial and error. Reasons for my question were curiosity and need for clarification.

So, do I understand it correctly, that square brackets are to be used only for arrays in AutoIT? And in Web Browser DOM (or elsewhere) round brackets are to be used instead (in places of square ones)?
