Question

So I have this javascript as my call:

$("#addNewThankYou").click(function () {
    var thankYouNote = $("#thankYouNote").html();

    var name = $("#enteredName").html();

    $.getJSON("/Home/AddEntryToDatabase", { Name: name, ThankYouNote: thankYouNote }, function (data) {
    ...
    });
});

The C# method behind is pretty standard:

public ActionResult AddEntryToDatabase(String Name, String ThankYouNote){
...
}

My problem lies potentially in the length of the string being passed in. For example, if I pass in a name and a note that are small (< 100 characters) I dont have any issues, it fires the method just fine. However, if I have a note that is pretty long, it doesn’t fire the method at all; when I click the button that calls the addNewThankYou.click is doesnt do anything. I tried putting a breakpoint on the first line of the method that gets called, and it doesn’t go in at all.

So, my question is this. Is there a limit to the string size that I can pass through the getJSON jQuery method? If so, any suggestions on how to get around this? I dont want to limit these thank you notes to 100 characters!

Historically you’ve always needed to treat long query strings (ie GET requests) with caution. In days gone by I believe query strings were restricted in length. It would probably be better if you were sending a large amount of data to use a ajax – POST instead.
