Get jQuery to read arrayed ID's

I have a modular table, its size depending on the array that makes it. Its ID would look something like "AA[0][1][A]"

 

Haven't found anything that I can pinpoint at but it seems like jQuery doesn't like arrayed ID's. My normal ID's work when jQuering like

alert($("#I001").val());

but the moment try to do it in the form of my array ID it's a dud. I've tried

alert($("#AA[0][1][A]").val());

As well as 

var IDValue = "AA[0][1][A]";
alert($("#" + IDValue).val());

And still nothing. Everything always comes back as "undefined."

 

Feels like an amateurish mistake but it's hooked me and I can't let go. I need to know why my jQuery isn't working, well the array ID at least, normal ID is fine.

Don't think HTML supports ids like that. AFAIK only characters a-z (upper/lower case), 0-9, underscores, hyphens and periods are supported. Ids should be unique, there should not be multiple items sharing the same name.

 

Named  form elements can supports arrays. I have used this in the past when bult processing multiple entries in a form.

It would help if you posted the html of the table itself. Perhaps theres a better way of creating it? Or getting whatever you want from it.

It's old. Literally just a tbody with text fields in each position, each having an ID generated from the array. Table number, Y pos and X pos.

 

I'll make a 21st century table hopefully in the next few months but for now I just need to get jQuery to cooperate.

This is bad, and i highly recommend trying to find out why what you're currently doing isn't working. 

 

For now though try using an attribute selector or escaping the meta-characters:

alert($('[id="#AA[0][1][A]"]').val());
alert($("#AA\\[0\\]\\[1\\]\\[A\\]").val());

Spent a whole day yesterday looking up possible things I could use. Found escape special characters, tried to see if they could work, they did. Been up and running for a day now.
