How to set encoding in .getJSON jQuery

In my web app, I submit some form fields with jQuery's $.getJSON() method. I am having some problems with the encoding. The character-set of my app is charset=ISO-8859-1, but I think these fields are submitted with UTF-8.

How I can set encoding used in $.getJSON calls?

If you want to use $.getJSON() you can add the following before the call :

$.ajaxSetup({
    scriptCharset: "utf-8",
    contentType: "application/json; charset=utf-8"
});

You can use the charset you want instead of utf-8.

The options are explained here.

contentType : When sending data to the server, use this content-type. Default is application/x-www-form-urlencoded, which is fine for most cases.

scriptCharset : Only for requests with jsonp or script dataType and GET type. Forces the request to be interpreted as a certain charset. Only needed for charset differences between the remote and local content.

You may need one or both ...

I think that you'll probably have to use $.ajax() if you want to change the encoding, see the contentType param below (the success and error callbacks assume you have <div id="success"></div> and <div id="error"></div> in the html):

$.ajax({
    type: "POST",
    url: "SomePage.aspx/GetSomeObjects",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: "{id: '" + someId + "'}",
    success: function(json) {
        $("#success").html("json.length=" + json.length);
        itemAddCallback(json);
    },
    error: function (xhr, textStatus, errorThrown) {
        $("#error").html(xhr.responseText);
    }
});

I actually just had to do this about an hour ago, what a coincidence!
