基于jquery实现的图片在各种分辨率下未知的容器内上下左右居中

  DIV:

  

复制代码 代码如下:

  <div class="pic_conent">

  <div class=" fn-pr pic_layer">

  <!--图片文字介绍透明层-->

  <section class="bg text_layer_home p10 font-yahei fn-bc">

  <h2 class="f14 fefefe">${pic.desc}</h2>

  <aside class="f12 bbb">

  <c:if test="${not empty pic.poi}">

  <span class="scenery fn-fl">${pic.poi}</span>

  </c:if>

  <span class="fn-fr mt10">by ${pic.username}</span>

  </aside>

  </section>

  <img src="${pic.picUrl}" width="320" height="420" />

  </div>

  </div>

  CSS:

  

复制代码 代码如下:

  .pic_conent{

  height: 720px;/*这个高度会被js改掉*/

  text-align: center;

  display: table-cell;

  vertical-align: middle;

  }

  .pic_layer{text-align:center; width:100%; display:inline-block; vertical-align:middle;}

  jquery:

  

复制代码 代码如下:

  $(function() {

  var surH = $(window).height();

  $(".pic_conent").height(surH);

  window.onresize=function(){

  var surH = $(window).height();

  $(".pic_conent").height(surH);

  }
