Question

我正在使用以下代码，似乎无法弄清楚它为什么不起作用。我的目标是根据右侧6个图像之一的点击更改.featured-artist类的背景图像。

JQUERY

<script>
    $('.artist-photo img').click(function(){
  var images = $('.artist-photo img').attr('src');
    $('.featured-artist').css('background-image','url('+images+')');
});
</script>

CSS

.featured-artist {
    background-image: url('http://michaelfroseth.com/clients/postedprints/html/img/ER 8 (original) copy.png');
    margin-left: 0px;
    margin-right: 0px;
    padding-left: 0px;
    padding-right: 0px;
}

有没有人有一个工作的jsfiddle使用类似的功能，我可以学习？

Answer 1

我发现你的脚本存在两个问题;

您正在为图片变量分配多个值
您的背景图片网址缺少引号

试试这个

<script>
$(".artist-photo img").click(function(){
var images = $(this).attr('src');
$(".featured-artist").css("background-image","url('"+images+"')");
});
</script>

通过jQuery更改CSS背景图像不起作用
