jQuery Raty set score inside click event

Question

I'm trying to use this rating plugin but I was unable to set the new score on click.

I'm making an ajax request on click event and get new calculated score. I wanted to set the new score inside the click event. What is the right way to do it?

<div class="rating" data-id="some-int" data-score="0.5"></div>

Javascript:

$(".rating").raty({
    score: function () { return $(this).attr("data-score"); },
    click: function (score, evt) {
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "./ajax.asmx/RateImage",
            data: "{ ImgId: " + $(this).attr("data-id") + ", Score: " + score + "}",
            dataType: "json",
            async: false,
            success: function (result) { actionResult = result.d; }
        });

        if (actionResult.Success) {
            console.log("Score: " + actionResult.Message);
            score = actionResult.Message;
        } else { // cancel rating
            alert(actionResult.Message);
            return false;
        }
    }
});

There is a built in method to set new score, so just use:

$('.rating').each(function(i) {
    var thisRating = $(this);
    thisRating.raty({
        score: function () {
            return $(this).data('score');
        },
        click: function (score, evt) {
            $.ajax({
                type: 'post',
                contentType: 'application/json; charset=utf-8',
                url: './ajax.asmx/RateImage',
                data: {
                    ImgId: thisRating.data('id'),
                    Score: score
                },
                dataType: "json",
                success: function (result) {
                    thisRating.raty('score', result.d.Message);
                }
            });
            return false;
        }
    });
});

Under docs - Functions you will find:

$('#star').raty('score');

Get the current score. If there is no score then undefined will be returned.

$('#star').raty('score', number);

Set a score.

You can do

$(".rating").raty('setScore', score);

See it working

According to the documentation, you can simply do $('#selector').raty({score: 3}) to set the score. So in the callback, you can call $(".rating").raty({score: actionResult.Message}) like so:

$(".rating").raty({
    score: function () { return $(this).attr("data-score"); },
    click: function (score, evt) {
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "./ajax.asmx/RateImage",
            data: "{ ImgId: " + $(this).attr("data-id") + ", Score: " + score + "}",
            dataType: "json",
            async: false,
            success: function (result) { actionResult = result.d; }
        });

        if (actionResult.Success) {
            console.log("Score: " + actionResult.Message);
            $(".rating").raty({score: actionResult.Message});
        } else { // cancel rating
            alert(actionResult.Message);
            return false;
        }
    }
});
