jQuery Raty 在点击事件中设置分数

Question

我正在尝试使用 this 评分插件，但我无法在点击时设置新分数。

我正在对点击事件发出 ajax 请求并获得新的计算分数。我想在点击事件中设置新分数。正确的做法是什么？

<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;
        }
    }
});

根据文档，您只需执行 $('#selector').raty({score: 3}) 即可设置分数。所以在回调中，你可以这样调用 $(".rating").raty({score: actionResult.Message})：

$(".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;
        }
    }
});

有一个设置新分数的内置方法，所以只需使用：

$('.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;
        }
    });
});

在docs - Functions下您会发现：

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

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

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

Set a score.

你可以做到

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

看看效果如何
