For those who are already utilizing jQuery, rejoice in the fact that you have the capability to parse a JSON string using jQuery.parseJSON.
If jQuery isn't part of your toolkit and you prefer not to use it, fear not! You can still make use of the fantastic JSON.parse or json_parse, crafted by none other than the esteemed Douglas Crockford himself.
I highly recommend steering clear of using eval() unless absolutely necessary.
My proposal is to simply... take no action. I am assuming that the serialized outcome will be included along with the page and/or an extra HTML fragment.
// Within a JavaScript section on the ASP page
var myObject = <%= JSONIfiedObjectResult %>;
This method works effectively as JSON falls within the range of JavaScript literals. Please note that quotes were not placed around the <%= %>.
If de-serialization occurs from an AJAX call returning JSON, refer to Zack's response.
Quite a simple solution - just execute
var x = eval(theString);
This code snippet usually covers everything except for ASP.Net's specific way of serializing DateTime, which is not compatible with standard JSON and serves as an extension in ASP.Net. If you want to utilize ASP.Net's deserializer, ensure that you have included an <asp:ScriptManager> tag in your webpage, and then use
var x = Sys.Serialization.JavaScriptSerializer.deserialize(theString);
By doing so, you will trigger the special Date handling mechanism, potentially enhancing the security aspect of your application.
Very typical, somewhat risky:
eval('(' + json + ')');
A neat feature of jQuery, but still poses security risks:
(new Function('return ' + json))();
