如何使用jquery獲取data-src屬性？

Question

其實我想做的事情，當我徘徊關閉第一個圖像必須被再次出現 我想順便說你

<div class="tur-list-box"> 

    <div class="tur-list-content"> 
     <figure> 
      <img data-src="img/assets/tourlist-2.jpg" class="lazy" src="img/assets/placeholder.png" alt="tur sayfası"> 
      <a href="#" class="figure-overlay"> 
       <p class="tour-price"> 
       <span class="price-big">73,</span> 
       <span class="price-little">40</span> 
       <span class="price-unit">TL*</span> 
       <span class="price-block">‘den itibaren</span> 
       </p> 
      </a> 
     </figure><!-- tur resim--> 

     <div class="tur-details"> 
      <h3><a href="#">Hafta Sonu Turları</a></h3> 
      <p>15 farklı program</p> 
      <i class=" open-tur-toggle fa fa-chevron-down" aria-hidden="true"></i> 
     </div><!-- tur detay--> 

    </div><!-- tur list content--> 

    <div class="tur-list-toggle"> 
     <ul class="list-unstyled"> 
     <li><a href="#" data-img="http://cdn.anitur.com.tr/resimler/orta/2016-02/otel_buyuk-abant-oteli_vPYKBnet58y0itPrkpce.jpg">Kakava (Hıdırellez) Şenlikleri Alaçatı <i class="fa fa-chevron-right" aria-hidden="true"></i></a></li>

<script> 
$(".tur-list-box").hover(
    function(){ 
     $(this).find(".tur-list-toggle").stop().slideDown(); 
     $(this).find(".open-tur-toggle").stop().removeClass("fa-chevron-down").addClass("fa-chevron-up"); 
    }, 
    function(){ 
     var getDefaultImg = $(this).find("figure img").data(".lazy"); 
     console.log(getDefaultImg); 
     $(this).find(".tur-list-toggle").stop().slideUp(); 
     $(this).find(".open-tur-toggle").stop().removeClass("fa-chevron-up").addClass("fa-chevron-down"); 
    } 
); 

$('.tur-list-toggle ul li a').hover(
    function(e) { 
     e.preventDefault(); 
     var getAttr = $(this).attr("data-img"); 
     $(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

分享我的結構，如果你不能看到data-src上檢查元素嘗試簽出源代碼（按Ctrl + U鉻）

Answer 1

$（本）.attr（ 「數據-SRC」）

您可以檢查此鏈接瞭解更多信息How to get the data-id attribute?

Answer 2

您可以嘗試使用以下行：

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

更多關於數據功能在這裏：https://api.jquery.com/data/

Answer 3

$(selector).data("src")將獲取的數據src屬性

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

Answer 4

的價值

你其實想要src而不是data-src屬性以便在懸停後查找圖像的來源，如代碼所示，因此它是var getDefaultImg = $(this).find("figure img").attr("src");。

這是因爲您使用的延遲加載圖像插件在加載圖像完成時將data-src替換爲src。

例如（從plugin's demo拍攝）

<!--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==">
