Hopefully you have used both JSLint.com or JSONLint.com to validate and maybe just for some formatting of your code. If you haven’t, shame!
I work at Sencha providing crazy fast support on the forums and a lot of times I need to look at the response people are using. Either it’s JSON, JSONP or on a bad day it’s XML. I use JSONLint.com to make the JSON or JSONP readable and also tell me if it’s even valid. JSONLint.com does a fantastic job for me but when I have JSONP I have to manually remove the callback function to only have the JSON or else JSONLint.com will yell at me.
So I decided to do something about it and registered JSONPLint.com just so I can make sure the actual JSON is valid and also see if the JSONP is actually valid. I found out Zach Carter actually does the pure JavaScript JSON validation behind JSONLint.com and has the code up on GitHub (here) which is fantastic and makes my life easier. All I have to do is remove the callback function and validate the actual JSON which is easy. So I modified Zach Carter’s example to do just that and did some coloring to fit my own needs for a first draft.
What’s next? First, need to clean it up. Got the first draft done but there is a better way to strip out the callback function. After that I would like to support url calling where you can pass params and headers so you can lint remote JSONP right from JSONPLint.com
