评级系统运行正常,根本不使用js。我将评级存储在数据库中。
如果我想更改评级并从数据库中检索评级,我应该对CSS进行哪些更改以显示存储的评级?
例如,我之前评价了四星级的东西。当我点击编辑页面时,我可以看到它被4星评级,我仍然可以将它改为1星或5星。

使用服务器端脚本在第4个(或任何一个)选项上设置checked
属性:
<span class="star-rating col-sm-10">
<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>
答案 1 :(得分:1)
将checked
属性添加到所需的input
:
<span class="star-rating col-sm-10">
<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" checked><i></i>
<input type="radio" name="rating" value="4"><i></i>
<input type="radio" name="rating" value="5"><i></i>
</span>
您还需要添加此CSS
.star-rating input:hover ~ input:checked + i {
opacity: 0;
}
.star-rating {
font-size: 0;
white-space: nowrap;
display: inline-block;
width: 150px;
