Can you send JSON through a url?

I have a ruby hash where the keys are urls and the values are integers. I convert the hash to JSON and I'm wondering if I'll be able to send the JSON inside a url via an AJAX request and then pull that JSON from a params hash.

Also, I am going to be sending a JSONifyed ruby hash back to the client. If I have a success callback in my AJAX function where I receive the data in a data variable, how do I parse that JSON with JQuery?

Please let me know if I need to be more specific.

Yes, you can with no problem. No manual encoding/decoding needed!

Your code would be like this:

var jsonParam = '{"name":"Edgar"}'; //Sample json param
$.ajax({
  ...  
  type: "get", //This sends in url
  data: {jsonParam: jsonParam}, //This will encode your json for url automatically
  dataType: "json", //With this the response will be automatically json-decoded!
  success: function(response){ //Assuming your server output was '{"lastName":"Villegas"}' as string
     alert(response.lastName);
  }
});

As you can see, no manual encoding/decoding was needed. Jquery handles it all!

Hope this helps. Cheers

PS: If, for some reason, you need to encode/decode your json manually for url use javascript's encodeURIComponent(string) and $.parseJSON(jsonString) methods.

Yes you can pass the json object as a get or post parameter.

In order to parse json string using Jquery you can use $.parseJSON.
