The example in this article describes how jquery implements a Taobao star rating function and is shared with you for your reference. The specific method is as follows:
The html part of the code is as follows:
<body>
<div id="div">
<ul>
<li>☆</li>
<li>☆</li>
<li>☆</li>
<li>☆</li>
<li>☆</li>
</ul>
</div>
<p id="p"></p>
<p id="score"></p>
</body>
In the above code:
id="p"show real-time score
id="score" displays the final score
The javascript code is as follows:
<script type="text/javascript">
$(function () {
//为所有的li标签绑定mouseout和mouseover事件。bind({事件名：function(){},事件名：function(){}})的方法绑定多个事件
$("#div li").bind({
mouseout:function () {
$(this).css("color", "black").html("☆").prevAll().css("color", "black").html("☆")
},
mouseover: function () {
$(this).css("color", "red").html("★").prevAll().css("color", "red").html("★")
}
});
//=实时显示分数.【index】搜索匹配的元素，并返回相应元素的索引值，从0开始计数。
$("#div li").mouseover(function () {
$("#p").html(parseInt( $(this).index("#div li"))+1);
});
//鼠标按下时，确定分数。额，就不更改了，大局已定。
$("#div li").mousedown(function () {
$("#score").html(("你选择的分数是" + (parseInt($(this).index("#div li")) + 1)));
$(this).css("color", "red").html("★").prevAll().css("color", "red").html("★")
//全部li标签的绑定事件全部清除--unbind方法可以加参数清除特定的事件。不加全部清除
$(this).unbind().prevAll().unbind().nextAll().unbind();
});
})
</script>
