The type of the data is always string. I also cannot specify the

Unfortunately I do not see jQuery providing similar function, while
Prototype does:
http://www.prototypejs.org/api/string/isJSON
Don't know how prototype implement this, and don't know if exists a
better way, but it works:
function isJson(string) {
return typeof(eval("(" + string + ")")) == 'object';
}
stringjson = '{"type": "menu","value": "File","items": [{"value": "New",
"action": "CreateNewDoc"},{"value": "Open", "action":
"OpenDoc"},{"value": "Close", "action": "CloseDoc"}]}';
stringhtml = '<p>Hello World!</p>';
alert(isJson(stringjson));
alert(isJson(stringhtml));
bye
