Can't Interpolate variable into a string

[Chris M.]

I have a JavaScript function that sends a GET request to a cgi script
and displays the results from the script. The call to the function
looks like this:

ajaxpack.getAjaxRequest("/cgi-bin/myscript.cgi",
"searchstring=cooking&pageone=Submit", processGetPost, "txt")

This works, and I get the correct results back. But I want to replace
the searchstring "cooking" with the value of a variable called
"search". I have tried several different ways to interpolate this
variable, but have not found the correct syntax.

Can anyone help me out?

Thanks!

on back or on sent ?

"searchstring="+search+"&pageone=Submit", processGetPost, "txt")

If 'search' is a global variable defined in another part of the
script, maybe:

ajaxpack.getAjaxRequest("/cgi-bin/myscript.cgi",
"searchstring=" +search +"&pageone=Submit", processGetPost, "txt")

`search' does not have to be declared a global variable for this to
work. It only needs to be the name of a property of an object in the
scope chain; that includes global variables but does not exclude the
other possibilities.

Thanks for the replies, folks,

I solved the problem by using the eval() method. I constructed the
required function call to
my ajaxpack.getAjaxRequest function as a long string, then put it into
eval(), which created
executable JavaScript code .

(Sorry for the newbie-ish question. I'm a Perl programmer who is
slowly getting the hang of JavaScript!)

Sounds like the worst possible solution. A good solution has already
been posted; I suggest you use it.
