Do I need something like this:
eval(''('' + this.header(''X-JSON'') +
'')'')
(taken from Cody Swann,
http://ajaxian.com/archives/prototype-extension-dynamic-script-pattern-support
).
I''m guessing my problem is simpler, and I''m leaving something
small out
related to the header though.
Thanks for any help
-Mark
1. evalJSON: function() {
2. if(this.transport.json){ return this.transport.json; }
3. else
4. {
5. try {
6. return eval(''('' +
this.header(''X-JSON'') + '')'');
7. } catch (e) {}
8. }
9. }

...whoops, forgot to pass my parameters into the Ajax.Request. So now the Ajax.Request is successfully completing (knew that was something small) ...but I still get a return (in the alert: alert(json ? Object.inspect(json) : "no JSON object");) of "no JSON object" ... hmmm.....

Search for a thread entitled "Automatic JSON response evaluation in prototype 1.5.1" and you should probably find what you need. Unfortunately, that thread was never specifically resolved because the original poster seemed to have some form of problem in his JSON but either way it does explain the automatic JSON evaluation in prototype. - Dash - Mark Holton wrote:> ...whoops, forgot to pass my parameters into the Ajax.Request.
