Question

我正在处理一个星级评分页面，我正在使用rateYo插件（http://rateyo.fundoocode.ninja）。如果我使用一个星级评级，一切正常，但我需要在此页面上动态使用它，从数据库中获取产品数据。我最初的想法是使用类与ID在页面上有多个并使用带有一些模拟数据的循环：

var demoRatings = [3.5, 4, 2, 1.5, 5, 4.5, 2.5, 1],
    stars       = $('.rateYo');

for (var i = 0; i < stars.length; i++) {
  $('.rateYo').rateYo({
    halfStar: true,
    rating: demoRatings[i],
    readOnly: true
  });
};

虽然我没有尝试这个错误并显示所有评级部分，但它只显示数组中第一个项目的星星（3.5）。知道我在这里缺少什么，或者这可以像这样使用吗？我将包含小提琴链接并使用下面的代码片段。谢谢你的帮助。

  $('.rateYo').rateYo({
    halfStar: true,
    rating: demoRatings[i],
    readOnly: true

Answer 1

问题在于您尝试更改已初始化的元素上的RateYo设置。例如，您将代码更改为

query.setHint("toplink.jdbc.fetch-size", "100");

它会起作用。

以下是使用元素中的 data - 属性的示例。

for (var i = 0; i < stars.length; i++) {
  $('.rateYo').eq(i).rateYo({ // select by index as an example
    halfStar: true,
    rating: demoRatings[i],
    readOnly: true
  });
}

$('.rateYo').each(function() {
  $(this).rateYo({
    halfStar: true,
    rating: this.dataset.rating,
    readOnly: true
  });
});

使用each from jQuery的绝佳机会：

var demoRatings = [3.5, 4, 2],
  stars       = $('.rateYo');

stars.each(function(i) {
  $(this).rateYo({
    halfStar: true,
    rating: demoRatings[i],
    readOnly: true
  })
});
