Hello,
I am experience some problems reading a form variable from a
Javascript function. The point with this particular variable is that
its name has the following syntax:
<input name="tx_impexp[tt_content:159]"/>
I want to set this var to 1 from my javascript function, so I tried
to execute the following line of code:
document.frm_1. tx_impexp[exclude][tt_content:159].value=1;
Unfortunately the following error come up:
Error: missing ] in index expression
document.frm_1. tx_impexp[exclude][tt_content:159].value=1
--------------------------------------------------------------|
It seems Javascript expects to close down the bracket at the position
marked...An easy solution would be to change my var syntax but the
point is that I cannot since I am using an already made script and I
should not modify it.
Just wandering if this is due to a syntax error defined according to
Javascript specification language or there is something wrong with
this. Maybe there is a work-around to get this done. Any help would be
highly appreciated.
Thank you very much!

You can use document.getEle mentByName('tx_ impexp[tt_content:159]')
[0].value = 1; (or maybe for your example use
document.getEle mentByName('tx_ impexp[tt_content:159]')[exclude].value
= 1;
OR
You can provide an id attribute and find it using that (i.e. using
getElementById( 'value')) without interfering with the name attribute.

Sorry, document.getEle mentsByName('tx _impexp[exclude][tt_content:
159']).value it seems to work, at least no error is raised, but what
is actually happening is that getElementsByNa me is returning an
undefined value.

Nice work-around!!! I did it and well, it worked!

No, it doesn't. It returns a (possibly empty) collection.

OR
You can use a reliable cross browser method that is mentioned in the FAQ
to answer this specific type question. Bracket Notation is your friend
when dealing with form elements.

Hello all,
I've made a data structure and an associated set of functions to enable me
to store a dynamically-sized array of elements of whatever data type I like.
Well that's the idea anyway...
My implementation seems to work great for primitive types, structures and
unions, but I can't quite get an array of function-pointers working
properly. Here's a very reduced version of my code with error checks removed
for the sake of brevity.

Hey everyone,
I'm currently reading Sitepoint's 'Javascript Anthology' and keep
spotting a reference I'm not quite familiar with, such as
'document.getElementByTagName('p')'. What I want to know is if this
reference points to the first element with the containing object?

Hi,
Task :
-Capture a HTML table with use of regular expression from a text string buffer(entire document).
–Pass it to another function to create a multi dimension array out of it.
- Pass it to another function to build it into a RTF table.
-Then return it back to the regular expression to replace the search result.
Difficulty:
-The regular expression doesn’t pass the back referenced table fields to the next function.

could change. However, since I'm trying to reference a control on a

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
