星级评级系统，给出独特的评级

Star rating System, Give unique rating

本文关键字：系统      更新时间：2023-09-26

我使用星星系统从数据库中对一些电影进行评级，我将这些电影添加到while循环中，并与每部电影一起使用星星。

我希望用户对每部电影给出唯一的评价，比如如果用户给了一部电影5颗星，那么如果他试图给其他电影5颗星，必须有一些指示显示在提交评级之前，将星星从黄色变为红色。谁能给我一些样品?

<form method="get" action="" id="form1">
  <span class="star-rating star-5">
          <input type="radio" name="rating" value="1"><i></i>
          <input type="radio" name="rating" value="2"><i></i>
          <input type="radio" name="rating" value="3"><i></i>
          <input type="radio" name="rating" value="4"><i></i>
          <input type="radio" name="rating" value="5"><i></i>
        </span>
</form>

一旦这个问题得到解决，我将使用PHP存储评级。下面是我正在使用的代码:

感谢您的帮助:-)' '

添加一个类别already-given到已经给定的评级，这样如果这个类别与先前的star-rating类别存在，它将使用橙色星号

.star-rating.already input:hover+ i
{
  background: url('/*Url of orange star*/');!important
}
<form method="get" action="" id="form1">
  <span class="star-rating star-5 already-given">
          <input type="radio" name="rating" value="1"><i></i>
          <input type="radio" name="rating" value="2"><i></i>
          <input type="radio" name="rating" value="3"><i></i>
          <input type="radio" name="rating" value="4" checked><i></i>
          <input type="radio" name="rating" value="5"><i></i>
        </span>
</form>

Jquery代码

$(document).ready(function(){
  $("input[type=radio]").on("change",function(){
    $(this).parents(".star-rating").removeClass("already-given").addClass("already-given");
  });
});
编辑:

jsfield demo (请删除红色，url为橙色星号)

也检查这个(根据注释中的要求进行更改)

看看这个最简单的创建星级的方法HTML, CSS和Javascript。在这里，您可以在评级div之后创建一个新元素，以显示或存储您想要的电影的评级索引。
