如何更改标签 div 中的属性？ [复制]

Question

我想替换属性 img 时遇到问题。 在class="HotProject_item HotProject_item_preview isotope-item" content class="content-asset" 有 <img src="/Uploads/images/0110/112/image012.jpg" 。

我想用新图像更改 img src。你能帮助我吗？

<div class="HotProject_item HotProject_item_preview isotope-item" zorder="1" row-num="1" data-id="149" 
enddate="31/12/2014" mark="10" style="position: absolute; left: 0px; top: 0px; -webkit-transform: translate3d(0px, 0px, 0px);"> 
<div class="content content_1 work" data-id="149" orgclass="content_1" curclass="content_1"> 
<div class="content-tl"> 
<div class="content-tr">

</div> <div class="content-bl"> <div class="content-br"> <div class="content-main"> 
<div class="content-mask-tl"></div> <div class="content-mask-tr"></div> <div class="content-mask-bl"></div> <div class="content-mask-br">
</div> <div class="content-inner"> 
<div class="content-top"> 
<div class="content-asset"> <a href="javascript:void(0);" data-id="149"> <img src="/Uploads/images/B%C3%ACnh%20ch%E1%BB%8Dn%20sp/thang%207/tu-lanh-1.jpg" alt=""> </a>

Answer 1

这样做

$(".content-asset img").attr("src","newimg.jpg");

意思是，改变它的source属性指向newimg.jpg
