来自数据属性的jQuery UI滑块设置值

Question

嘿我有一些叫做"lp-slider"的jquery滑块设置如下:

                 <div class="xs-col-12">
                        <div class="col-xs-2 label label-default">Grit</div>
                        <div class="col-xs-9">
                            <div class="lp-slider" data-lpScore="30"></div>
                        </div>
                        <div class="col-xs-1"><img class="slider-img" src="images/close-white.png"></div>
                        <br class="clear-fix">
                    </div>
                    <div class="xs-col-12 spacer-med">
                        <div class="col-xs-2 label label-default">Self-efficacy</div>
                        <div class="col-xs-9">
                            <div class="lp-slider" data-lpScore="30"></div>
                        </div>
                        <div class="col-xs-1"><img class="slider-img" src="images/close-white.png"></div>
                        <br class="clear-fix">
                    </div>
                    <div class="xs-col-12 spacer-med">
                        <div class="col-xs-2 label label-default">Sociability</div>
                        <div class="col-xs-9">
                            <div class="lp-slider" data-lpScore="30"></div>
                        </div>
                        <div class="col-xs-1"><img class="slider-img" src="images/close-white.png"></div>
                        <br class="clear-fix">
                    </div>

我想在它们上运行每个语句,以便它抓取data属性并使用它来设置滑块值.我试过这个,我似乎无法弄清楚如何让它工作.它设置滑块但值部分无法正常工作:

$(".lp-slider").each(function() {
    var value = $(this).data("lpScore");
    $(this).slider({
        value:value,
        range:"min",
        min:1,
        max:100,
        step:1
    });
});

要使用jQuery获取数据属性,data()您必须以小写形式编写它lpscore.

这里对数据应用的规则进行了深入的解释.使用jQuery的数据属性

码:

$(".lp-slider").each(function () {
    var value = $(this).data("lpscore");
    $(this).slider({
        value: value,
        range: "min",
        min: 1,
        max: 100,
        step: 1
    });
});
