Invalid JSON format

ajax, asp.net, jquery

Solution

In JSON, the keys must be quoted with double quotes (`"`), not single quotes (`'`). Similarly, string values must be in double, not single, quotes. You're using single quotes. For example, around `authorId` and around the text of the title.

So at a minimum, you need to swap those quotes around, e.g.:

data: '{"authorID" : "' + authorID +
      '", "title" : "' + encodeURIComponent(blogTitle) +
      '", "msg" : "' + encodeURIComponent(blogBody) +
      '", "preview" : "' + encodeURIComponent(mediaContent) +
      '", "layoutID" : "' + previewLayoutId +
      '", "threadID" : "' + threadID + '"}'

Problem

I'm building JSON object and passing it to server with JQuery ajax. ``` data: "{'authorID' : '" + authorID + "', 'title' : '" + encodeURIComponent(blogTitle) + "', 'msg' : '" + encodeURIComponent(blogBody) + "', 'preview' : '" + encodeURIComponent(mediaContent) + "', 'layoutID' : '" + previewLayoutId + "', 'threadID' : '" + threadID + "'}" ``` But when my blogBody variable contains `'` the code fails with the error message: ``` {"Message":"Invalid object passed in, \u0027:\u0027 or \u0027}\u0027 expected. (107): {\u0027authorID\u0027 : \u0027148385\u0027, \u0027title\u0027 : \u0027123213\u0027, \u0027msg\u0027 : \u0027%3Cp%3Eqqq%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3E\u0027\u0027\u0027\u0027%3C%2Fp%3E\u0027, \u0027preview\u0027 : \u0027\u0027, \u0027layoutID\u0027 : \u00271\u0027, \u0027threadID\u0027 : \u00270\u0027}","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.GetRawParamsFromPostRequest(HttpContext context, JavaScriptSerializer serializer)\r\n at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"} ``` Could someone say where is the error and how to fix it?
