I'm hoping that someone can help me with a question I have about
javascript syntax.
I got an html page that uploads an image and some text field to a
database.
What I'd like to do is modify the content of one of the textfields
prior to it being submitted to the database. Specifically, I need to
append the contents of one of the fields to another.
The problem that I've encountered is that the textfield name contains
square brackets , ‘extra_fields[Price]'
I've identified the square brackets as being the problem by changing
the textfield's name to one that doesn't contain square brackets
,extra_fieldPri ce for example and the script works fine.
Unfortunately, in the real world application of this page, I can't
change the textfield name.
The specific part of the html page that's giving me problems is
<input type="button" value="Click to generate code" class="body-text"
onClick="extra_ fields[Price].value =
'$'+extra_field s[Price].value+'<br><A
HREF="../cgi-bin/processorder.cg i?'+caption.val ue+'~'+extra_fi elds[Price].value+'"> Add
to Order</A>'"></input>
I've tried puting backslashes before the square bracket,
"onClick="extra _fields\[Price\].value =
'$'+extra_field s\[Price\].value+'<br><A
HREF="../cgi-bin/processorder.cg i?'+caption.val ue+……………….."
Unfortunately the script didn't still doesn't work though.
I'm not that familiar with javascript syntax. Can anyone suggest how I
can have javascript read square brackets as a literal part of a
textfield's name rather than as some kind of syntax modifier
The entire page's html is as follows
Thanks for any suggestions
