我知道，如何通过点击某处来获取和更改网址，但我不知道如何获取背景图片的网址，然后在更大的图像处更改网址。

<img id="change-img" .. >

Answer 1

以下是您的回答，将background-image存储在变量中，删除url（）并将其替换为图像src

$(".ci-thumb").on("click",function(){
  var bg = $(this).css('background-image');
 bg = bg.replace('url(','').replace(')','').replace(/\"/gi, "");
 $("#change-img").attr("src",bg);
 })

.ci-top {
    clear: both;
    display: inline-block;
    width: 100%;
}

.top-left{
float: left
}

.ci-bottom {
    text-align: right;
}

.ci-thumb {
    height: 150px;
    width: 150px;
    margin: 0;
    display: inline-block;
}

.ci-thumb-1 {
    background-image: url(http://placeholder.pics/svg/300/FF2209);
}

.ci-thumb-2 {
    background-image: url(http://placeholder.pics/svg/300/5BFF76);
}

.ci-thumb-3 {
    background-image: url(http://placeholder.pics/svg/300/325BFF);
}
