问题描述
我找到了输入 type =radio的星级评分示例。
I found an example of star rating with input of type="radio".
这太棒了，但我想要更简单的东西。而不是输入 type =radio，请使用星级评分< span> 演示（演示）示例。
It's fantastic, but I'd like something simpler. Instead of input of type="radio", use star rating with <span> example in demonstration (demo).
以下代码
.holder {
height: 1%;
overflow: hidden;
position: relative;
left: 0;
}
.left {
float: left;
}
.rating {
border: none;
float: none;
display: block;
left: 0;
}
.rating>input {
display: none;
}
.rating>label:before {
margin: 5px;
font-size: 1.25em;
font-family: FontAwesome;
display: inline-block;
content: "\f005";
}
.rating>.half:before {
content: "\f089";
position: absolute;
}
.rating>label {
color: #ddd;
float: right;
}
/* Styles hover mouse stars. */
.rating>input:checked~label,
/* Show gold star when clicked */
.rating:not(:checked)>label:hover,
/* Hover current star */
.rating:not(:checked)>label:hover~label {
color: #FFD700;
}
/* Hover previous stars in list */
.rating>input:checked+label:hover,
/* Hover current star when changing rating */
.rating>input:checked~label:hover,
.rating>label:hover~input:checked~label,
/* Lighten current selection */
.rating>input:checked~label:hover~label {
color: #FFED85;
}

如何在不使用框架作为Bootstrap或其他框架的情况下仅使用CSS和jQuery在此代码中创建相同特征的星星？
How can I create stars of the same characteristics in this code using only CSS and jQuery without using frameworks as Bootstrap or others?
<div id="rating" class="rating">
<span class="stars"></span>
<span class="stars"></span>
<span class="stars"></span>
<span class="stars"></span>
<span class="stars"></span>
</div>
或者此代码：
<ul class="star-rating">
<li class="star-icon">☆</li>
<li class="star-icon">☆</li>
<li class="star-icon">☆</li>
<li class="star-icon half">☆</li>
<li class="star-icon full">☆</li>
</ul>
通过jQuery，获取所选值并将它们发送到数据库。
And by means of jQuery, get the selected values and send them to the database.
$(document).ready(function() {
$(document).on('submit', '#frm-rating', function() {
//Obtenemos datos form.
var data = $(this).serialize();
//Ajax
$.ajax({
type: 'POST',
url: 'rating.php',
data: data,
success: function(data) {
$("#result-rating").html(data);
}
});
return false;
});
});
目标是优化更简单的代码。
The goal is to have simpler code optimized.
示例：
.star-icon {
color: #ddd;
font-size: 2em;
position: relative;
display: inline;
direction: rtl;
unicode-bidi: bidi-override;
}
.star-icon:before{
content: '\2605';
position: absolute;
left: 0;
}
.star-icon.full:before {
color: #fde16d;
content: '\2605';
position: absolute;
left: 0;
}
.star-icon.half:before {
color: #fde16d;
content: '\2605';
position: absolute;
left: 0;
width: 50%;
overflow: hidden;
direction: ltr;
}
.star-icon.half:after {
content: '\2605';
position: absolute;
right: 0;
width: 50%;
overflow: hidden;
}
.star-rating > li:hover,
.star-rating > li:hover ~li:before,
.star-rating > li:hover ~li:after
{
width: 100%;
color: #fde16d;
cursor: pointer;
}
<ul class="star-rating">
<li class="star-icon">☆</li>
<li class="star-icon">☆</li>
<li class="star-icon">☆</li>
<li class="star-icon half">☆</li>
<li class="star-icon full">☆</li>
</ul>
现在要知道用户通过PHP和jQuery选择了什么评级。
Now to know what rating the user has chosen through PHP and jQuery.
更动态。
<?php
function calculate_stars($max, $rating){
$full_stars=floor($rating);
$half_stars = ceil($rating-$full_stars);
$gray_stars = $max-($full_stars + $half_stars);
return array ($full_stars, $half_stars, $gray_stars);
}
function display_star($rating){
$output="";
$number_stars = calculate_stars(5,$rating);
$full = $number_stars[0];
$half = $number_stars[1];
$gray = $number_stars[2];
$output ='<ul class="star-rating">';
if($gray)
for ($i=0;$i<$gray;$i++)
{
$output .= '<li class="star-icon">☆</li>';
}
if($half){
$output .= '<li class="star-icon half">☆</li>';
}
if($full){
for($i=0; $i<$full;$i++)
{
$output .= '<li class="star-icon full">☆</li>';
}
}
$output .='</ul>';
return $output;
}
echo display_star(4.3);
exit;
?>

HTML标记：
<ul class="c-rating">
<li class="c-rating__item rating is-active left" data-index="0"></li>
<li class="c-rating__item" data-index="1"></li>
<li class="c-rating__item left" data-index="2"></li>
<li class="c-rating__item" data-index="3"></li>
<li class="c-rating__item left" data-index="4"></li>
<li class="c-rating__item" data-index="5"></li>
<li class="c-rating__item left" data-index="6"></li>
<li class="c-rating__item" data-index="7"></li>
<li class="c-rating__item left" data-index="8"></li>
<li class="c-rating__item" data-index="9"></li>
</ul>
<input type="hidden" class="rank" />
我为此功能创建了一个自定义jQuery插件，您需要传递 childClass 用于子选择器， inputClass 用于输入标签选择器。
I have created a custom jQuery plugin for this functionality where you need to pass childClass for child selector and inputClass for input tag selector.
var activeClassCount = 1;
$.fn.customStarRatings = function(obj) {
var wrapper = this;
var stars = obj.childClass;
var input = obj.inputClass;
$(wrapper).hover(function() {
activeClassCount = $(this).find('.rating').index() + 1;
}, function() {
var $this = $(this);
$this.find(stars).slice(1, activeClassCount).addClass('is-active');
$this.find(stars).slice(activeClassCount, 10).not('.rating').removeClass('is-active');
// console.log($this.find(stars).slice(activeClassCount, 4).not('.rating'))
});
$(stars).hover(function() {
$(this).prevAll(stars).add($(this)).addClass('is-active');
$(this).nextAll(stars).removeClass('is-active');
});
$(stars).click(function(event) {
$(".rating").removeClass("rating");
$(this).addClass('rating');
activeClassCount = $(this).index() + 1;
$(this).prevAll(stars).addClass('is-active');
if (input) {
$(input).val(($(this).index() + 1)/2);
console.log($(input).val(), activeClassCount)
}
});
}
然后你必须在DOM准备就绪时调用这个jQuery函数。 / p>
Then you have to simply call this jQuery function when the DOM gets ready.
$(".c-rating").customStarRatings({
childClass: ".c-rating__item",
inputClass: ".rank"
});
PS HTML标记不仅限于使用< ul> 和< li> 仅限代码。您需要做的就是在评级和输入元素的包装标签上调用此自定义函数。
PS The HTML markup is not confined to usage of <ul> and <li> tags only. All you need to do is call this custom function on the wrapper tag of ratings and input element.
CSS编辑：
.c-rating {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
list-style: none;
margin: 0;
padding: 0;
}
.c-rating__item {
-webkit-box-flex: 0;
-webkit-flex: 0 0 12px;
-ms-flex: 0 0 12px;
flex: 0 0 12px;
height: 24px;
background-position: -12px 0px;
background-image: url(stars.svg);
cursor: pointer;
}
.c-rating__item.left {
background-position: 0px 0px;
}
.c-rating__item.is-active,
.c-rating__item: hover {
background-position: -36px 0;
}
.c-rating__item.left.is-active,
.c-rating__item.left: hover {
background-position: -24px 0;
}
对此函数的jQuery调用保持不变。检查工作小提琴此处。
The jQuery call to this function remains the same. Check the working fiddle here.
