Escaping "[]" characters

Copy linkTweet thisAlerts:
Feb 13.2004

I have an input text array on a form which gets parsed by PHP, so they must have [] on the end. Specifically, they’re called select[]. However, I have a javascript that needs to access the 6th and 7th elements if this array. Since javascript interprets [] characters as an array, how do I force it to use “select[]” as the object? i.e.: “select[]”[6].value

document.forms[whatever].elements['select[]'].value

@Chris-IAauthorFeb 13.2004 — Here's the exact line of code I used:

document.forms[report].elements['select[]'][6].value="STRING"

I got the error: 'document.forms[..].element' is null or not an object

I also tried this: document.forms[report].elements['select[]'[6]].value="STRING"

and came up with the same error ?

I'm assuming its not finding forms[report], am I misusing this?

@AdamGundryFeb 13.2004 — Sorry, I did not quote whatever because it could also have been a number if you were not using a named form. You need this:

document.forms['report'].elements['select[]'][6].value="STRING"
