RE: Some beginner questions
One thing to add/correct from Philip's response: #cgi.query_string# contains url parameters. You can reference those as url.variablename (or just variablename) to get the values most of the time. One exception to look out for on that is if you have a url like this: index.cfm?a=5&a=6&a=7 When the same variable is named several times, the variable only gets the last value in the url, not all three. In that case, you have to use the List*() functions to get the variables...

Sometimes you might have to escape them by changing " to "" but sometimes " will work. If you are sending info to a database you will probably put text fields in single quotes ' ' which means that you may have to escape the single quotes instead of the double quotes.

Re: Some beginner questions
1. Don't Know. 2. As far as I know you should be able to use almost anything in the data except #'s. 3. Just use the name of the field you want. IE: If #query_string# is ?cfid=1234&cftoken=76323661 Then to access just the pieces you would cfid = #cfid# cftoken = #cftoken# and you would get cfid = 1234 cftoken = 76323661 HTH, --K Katrina Chapman Consultant Ameriquest Mortgage "Cristi" e.west.ro>cc: Subject: Some beginner questions 05/31/00 07:50 AM Please respond to cf-talk Hello there.

RE: Some beginner questions
> 1) Can I call a JavaScript function from CF? > Smth. like > where f is a JavaScript function. > I tried , but it didn't work. No, you can't directly call a JavaScript function from CF; CF generates documents on the server, which are then sent back to the client, where any JavaScript will execute. You can use CF to write JavaScript, and you can use JavaScript to execute HTTP requests, and that's essentially the limit of any cross-communication between them. > 2) How do I manage strings containing special characters as > dbl. quote (i.e. ") > Should I prefix them with something. > I'd like to have an output like > say "hello" In CF, you can escape a double quote by doubling it: "This is my string, and ""this"" is double-quoted." > 3) How can I get the value of each field in a query string? > I know the #cgi.query_string# which returns the entire > query string, but I want to access specific fields If you're using CF 4.5, you can reference the URL structure, which contains each name-value pair within the query string. You might need to read up on Structures a little bit. Here's an example, which will loop over the URL structure and output the name and value for each URL parameter: #ThisURLParam#: #URL[ThisURLParam]# If you're using an older version, you can loop over the query string as if it were a list; the delimiter for the list is the ampersand (&).
