如何通过淘汰赛实现 CSS 星级评分
【中文标题】如何通过淘汰赛实现 CSS 星级评分【英文标题】:how to implement a css star rating with knockout 【发布时间】:2020-04-03 11:56:04 【问题描述】:有一个我想要实施的星级评定,它的工作范围是可以点击星星,我遇到的问题是当我显示多组星星时。发生的事情是点击了哪一组星星,它会影响另一组,只有改变点击的数量。如果我没有很好地解释,假设我有 3 颗星,我去第一组并给它一个 5 星评级,它保持这个值(都很好),但是如果去下一组星并给这个值说 2,这第二组将保持 2 星的值,但是上面的设置设置为无。就像检查的事件对于每个集合并不是唯一的并且重置另一个集合。我为此使用 bootstrap 和 Knockout js,我试图提供一个唯一的 ID,希望可以解决它,但没有运气。任何人都可以帮助解决这个问题?
下面的代码,我已经跳过了一些创建我的可观察数组的淘汰赛代码,我有这个工作,因为我为我的每个 feedbackToBeLeft 数组获得了一组星
<style>

【问题讨论】:
您需要独特的id
和for
和name
用于两组评级,如果您需要提供sn-p
在你上面的例子中,我没有看到一个独特的name
用于设置 2 个评级星
【参考方案1】:
这就是我会如何接近你想要做的事情。
var ratings = [

value: 1

name: 'Not Good',

【讨论】:
很好的例子非常感谢,我真的需要字体很棒的星星,我的例子与css和前后属性有关。我不知道如何正确操作这些,只是要从整个该死的事情重新开始:(以上是关于HTML 星级评定的主要内容,如果未能解决你的问题,请参考以下文章
