多个星级评分问题

Question

我有一个星级应用程序，用户可以在1到5之间投票。但现在它只允许单一评级，即如果我从第二个选择星号，第一个部分似乎是选择而不是第二个（总是默认第一部分）。我试图改变课程和身份，但它没有用。

Html代码：

<fieldset id='demo1' class="rating">
   <input class="stars" type="radio" id="star_a-5" name="rating" value="5" />
   <label class = "full" for="star5" title="Awesome - 5 stars"></label>
   <input class="stars" type="radio" id="star_a_5-half" name="rating" value="4.5" />
   <label class="half" for="star4half" title="Pretty good - 4.5 stars"></label>
   <input class="stars" type="radio" id="star_a-4" name="rating" value="4" />

请帮帮我。我该如何解决这个问题？

Answer 1

HTML中存在多个问题：

1. 您有多个具有相同id的元素，页面上的id永远不会超过1个元素。
2. 您的所有radio's都具有相同的name属性值。因此，如果您点击第一个评级，它将删除评级2或3的任何评级

我还更改了您的jQuery以使其更简单。基本上我改变了这一点：$("fieldset[id^='demo'] .stars")现在所有fieldset的{​​{1}}都以id

开头
＆＃13;
＆＃13;
demo
＆＃13;
$('document').ready(function() {
  $('.toggleswitch').bootstrapToggle();
  $("fieldset[id^='demo'] .stars").click(function() {
    alert($(this).val());
    $(this).attr("checked");
  });
});
＆＃13;

Answer 2

你的一些ids正在重复。重命名它。 在demo1中检查id =“star2half”

<input class="stars" type="radio" id="star2half" name="rating" value="2.5" />
<label class="half" for="star2half" title="Kinda bad - 2.5 stars"></label>

演示3：

<input class="stars" type="radio" id="star2half" name="rating" value="2.5" />
<label class="half" for="star2half" title="Kinda bad - 2.5 stars"></label>
