我想从图像单击获取数据链接属性.

i want to get data-link attribute form an image click .

以下是我的图片标签

<a href="#"  class="aclick">
    <img data-link="petroliumjelly.php" src="productsimgs/petroliumjelly.png" class="img-responsive" id="2">
</a>

要点击它，这就是我正在做的，

       $(".aclick").click(function (e) {
        e.preventDefault();

        var link = $(this).data("data-link");// tried both

    });

</script>

当我尝试记录或提醒它时，我无法定义 请帮我如何解决

推荐答案

下面是可帮助您的代码段.数据链接属性位于img标签中，而不位于"a"标签中.

Below is code snippet to help you. data-link attribute is in img tag and not in 'a' tag.

$(".aclick").click(function (e) {
        e.preventDefault();
        alert($(this).find('img').attr("data-link"));
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#"  class="aclick">
    <img data-link="petroliumjelly.php" src="productsimgs/petroliumjelly.png" class="img-responsive" id="2">
</a>
