      $(this).parents(".tur-list-box").find("figure img").attr("src",getAttr);
    },
    function(e) {

    }
);
</script>

and I want to share with you demo link to see how to work

顺便说一句，如果你看不到检查元素上的data-src，请尝试查看源代码（ctrl + U代表chrome）

Answer 1

$(selector).data("src")将获取data-src属性的值

https://api.jquery.com/data/

Answer 2

$（this）.attr（＆＃34; data-src＆＃34;）

您可以查看此链接以获取更多信息How to get the data-id attribute?

Answer 3

您可以尝试使用以下行：

var getDefaultImg = $(this).find("figure img").data("src");

有关数据功能的更多信息，请访问：https://api.jquery.com/data/

Answer 4

您实际上想要获取src而不是data-src属性，以便在悬停后找到图像的来源，正如您的代码所示，因此它var getDefaultImg = $(this).find("figure img").attr("src");

这是因为您使用的延迟加载图片插件在加载图片完成时将data-src替换为src。

例如（取自plugin's demo）

<!--image 6 load is complete-->    
<img class="lazy img-responsive" src="images/6.jpg?t=1477297898" style="display: block;">

<!--image 7 not loaded yet-->
<img class="lazy img-responsive" data-src="images/7.jpg?t=1477297898" src="data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==">

如何使用jquery获取data-src属性？
