roi,
I just updated the class to fix your issue. It’ll now return an empty string for any variables that don’t exist in the query string. I didn’t initially account for this because I figured people wouldn’t try to call variables that don’t exist, but that’s my mistake as they may be coming from a script and some may be missing. good catch and thanks for pointing it out.

[...] variables to not show, rather it just returns an empty string. You can get the update from the original post. AS3, query, QueryString, [...]

I’ve discovered a little bug with this script…

Lets say you are calling in 2 parameters from the url….

So you line them in in AS as

QueryString.getInstance().getValue(”myDate”);
QueryString.getInstance().getValue(”myTitle”);

if you do not supply the first var, which in this case is “myDate” and you supplied the “myTitle” only parameter, it will not be read in…if you comment out the first parameter mydate…myTitle would than show…..

Off course if all parameters are present to be read in, everything works fine….

thanks

off couse it does, lol I finally looked into the .as script itself and there it was the ExternalInterface.call (little evil hiding away ) and after hunting down the meaning of a singleton class…and just as we speak….im able to refresh my page and my textField is filled with one of the test parameters
Ok here your official thank you. Thank you.

Good class.

roi,
it will automatically take the current URL into account to gather the query string variables from. All you have to do is say QueryString.getInstance().getValue(”valueNameHere”); and it will return the variable that goes with that value. Hope that helps.

ok….for the life of me, how do we use this class?
I have added it in flash and setup its class path ok…

but how do we get the string to be evaluated into this class in the first place? How do we pass it the main url we want to evaluate?

Thanks

Andrew,
Certainly, but that is not what the class was made to do. If you want to have defaults you have to anticipate that in your code in AS and not actually through the query string or this class. You could, though, add a getter to this class for the pairs array and check to see if its length is greater than 0 which would mean there is a query string in the URL and if not then set the defaults in your app.

I was wondering if there was a way of passing a default value if no variable was present eg if:

http://www.reintroducing.com was sent with no variables you could set var1=one and var2=two as a default.

you could put it in the folder where your FLA is (the whole folder structure together, com.reintroducing..etc) or you could set it as a global classpath in your Flash preferences
