[mapserver-users] RE: javascript in html templates

[KenHeer1]

I did find the method you outlined but I was still having problems. After
digging deeper into the old javascript, I found where I could intercept the
response and process it as I needed; basically applying the raw html the way
I was before, then executing the script tags to replace the placeholders the
raw html created.

Thanks again for your help, without your suggestions it would have taken me
much longer to find the solution.

Sincerely, 

Kenny
