Avoid sending Ajax request parameters in query string style

While reviewing some code, I found someone calling jQuery Ajax like this:

$.ajax({
       type: “POST”,
       url: “/AddPost”,
       data:  “postText=”+ PostText ,
       dataType: “json”,
       success: function (status) {

       }
}); //$.ajax({

And as you see in the previous code, it is sending the data using this line: data: “postText=”+ PostText ,

This is like a query string style, this will work well but image the user inserted a special char in PostText, such as ?? you will get on the server un expected value “”jQuery15107041011152323335_1309357585354″”

So never use this style while dealing with Ajax calls, you need to post it in JSON style like this:

$.ajax({
        type: “POST”,
        url: “/AddPost”,
        data: { postText: PostText },
        dataType: “json”,
        success: function (status) {

        }
}); //$.ajax({

This will work whatever char the user will insert.
