        $(".rating-stars").ratingStars(ratingOptions);

        $(".rating-stars").on("ratingChanged", function (ev, data) {
            $("#ratingChanged").html(data.ratingValue);
        });

        $(".rating-stars").on("ratingOnEnter", function (ev, data) {
            $("#ratingOnEnter").html(data.ratingValue);
        });

        $(".rating-stars").on("ratingOnLeave", function (ev, data) {
            $("#ratingOnLeave").html(data.ratingValue);
        });
    </script>
</body>
</html>

使用前要有jquer插件库

第二种用循环

效果图

代码

for (let i = 0; i < res.data.length; i++) {
		    // let phot = res.data[i].score;
			let phot = parseInt(res.data[i].score);
			console.log(phot);
		    let stars = '';
		    for (let k = 0; k < phot; k++) { // 使用phot的数值进行循环
		        stars += `<p class='imgs'><img src="img/五角星.png" alt=""></p>`;
				console.log(stars);
		    }

使用这样的循环在相应的位置拼接
