Function doesn't work with long input parameter

Question

Below function works when the input string (#txtarea) contain few characters but doesn't work when it contain long string, how to get it working?

below is my code:

 $('#insertcmt').click(function () {
        $.getJSON('http://localhost:55679/RESTService.svc/InsertComment?callback=?', { commenttext: $('#txtarea').val() }, function (data) {
        });
        loadcomments();

    });

server side logic:

    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    public void InsertComment(string commenttext)
    {
        string sql = "INSERT statement";
        Database db = Utilities.GetDataBase();
        DbCommand cmd = db.GetSqlStringCommand(sql);
        db.ExecuteNonQuery(cmd);
    }

Is it because i am trying to access from Cross Domain?

you need to show your server logic and some examples of when it work and when it doen't — Ilya Ivanov, Mar 21 '13 at 16:30
This function escapes text var encoded = HttpUtility.HtmlEncode(unencoded); var decoded = HttpUtility.HtmlDecode(encoded); — Joan Caron, Mar 21 '13 at 16:36

This is probably caused by the limitation in the RFC GET request. Take a look at this question.

Since you are using an insert statement in your serverside logic, you should probably use a POST request anyways.

 $('#insertcmt').click(function () {
    $.post('http://localhost:55679/RESTService.svc/InsertComment?callback=?', { commenttext: $('#txtarea').val() }, function (data) {
    });
    loadcomments();
});

@Khan: Maybe that is caused by a cross-domain request. A common solution is using jsonp. See [this answer](http://stackoverflow.com/a/3506306/473475) for details on this :) However, this might also be a serverside issue. I am not an asp developer, and I don't really know how to debug this, sorry. – Esben Tind Mar 21 '13 at 21:32

Long URL (over 2000 characters) may not work in all web browsers.

Use a POST method:

$('#insertcmt').click(function () {
  $.post('http://localhost:55679/RESTService.svc/InsertComment?callback=', 
    { commenttext: $('#txtarea').val() }, 
    function (data) {

    });

  loadcomments();
});

Edit:

You'll have to change the [WebGet] attribute to:

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]

@Khan You have to change the atttribute [WebGet] to [WebInvoke(Method = "POST")] – Corneliu Mar 21 '13 at 17:06
I change to [WebPost(ResponseFormat = WebMessageFormat.Json)] but its not recognising WebPost – Khan Mar 21 '13 at 17:09
@Khan I've edited my comment, it should be [WebInvoke(Method = "POST")] – Corneliu Mar 21 '13 at 17:10

Try sending the content via POST, rather than a GET, there's no universal limit in theory.
