Stringing a variable

[rickpill]

Hi,

I am new to Javascript (mainframe background ) - I need some help!

I have a pop-up window with a drop down box where users selects any one of 7 options. Based on an option selected, I have to retrieve information from the main window: How do I string a variable form field name?

window.opener.document.all.???.value

where: ??? = "Selection1"

Thank you in advance,

Rick Pillay

Would something like this work?

window.opener.document.formname.fieldname.value;

I think that might be what you are looking for...

Thanks.

The 'fieldname' is a variable not a form field name.

Oh, sorry. Try this instead:

window.opener.fieldname;

That should return the fieldname variable from the window that opened the page.

Thanks!

Sorry, I don't think I explained this properly ...

parent.window:
Line1 'Buyer '
Line2 'Seller '
Line3 'Subscriber '

pop up window:
option 1
option 2
option 3 <==== Selected
.................
: Category: 123 :
.................

From the pop up window I need to string to Line3 (Parent window) the value 'Category: 123'. I am currently doing this with a bunch of 'if' statements - is there an easier way to do this, i.e. create a variable, string 'Line' + the Option selected into:
window.opener.document.formname.fieldname.value;

Thanks again,

Rick

So, you have a <select> and you want to know which one it is on? If so, try something like this:

window.opener.document.formname.selectname.options[window.opener.document.formname.selectname.selectedIndex].value; //all that on one line

I think that might be what you want... ;-)

Rick,

An eval statement might be helpful for you, there.

Here's a link to a discussion involving eval statements to build commands using variables:

Thanks AdamBrill and Edward! Just got back.

Edward, I'll give that a try. Thanks.
