Earlier this year, before I learnt about Code Review Stack Exchange, I gave this answer in response to a question about how to combine ASP.NET, jQuery, and JSON:
I keep thinking that there must be a better way to handle the JSON than just using escaped string literals, but I'd like to know for sure.
urlToHandler = 'handler.ashx';
jsonData = '{ "dateStamp":"2010/01/01", "stringParam": "hello" }';
$.ajax({
url: urlToHandler,
data: jsonData,
dataType: 'json',
type: 'POST',
contentType: 'application/json',
success: function(data) {
setAutocompleteData(data.responseDateTime);
},
error: function(data, status, jqXHR) {
alert('There was an error.');
}
}); // end $.ajax
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class handler : IHttpHandler , System.Web.SessionState.IReadOnlySessionState
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "application/json";
DateTime dateStamp = DateTime.Parse((string)Request.Form["dateStamp"]);
string stringParam = (string)Request.Form["stringParam"];
// Your logic here
string json = "{ \"responseDateTime\": \"hello hello there!\" }";
context.Response.Write(json);
}
dateStamp
andstringParam
values were not hardcoded, but rather read from a web form, the only way I know to build the JSON is string concatenation, and that's no fun and ugly as sin! \$\endgroup\$
