删除小部件后如何定位jquery Gridster? [英] How to position the jquery gridster after remove a widget?

问题描述

我可以删除小部件，但是在定位其余小部件时遇到了问题.

I can remove widget but I am facing problem with positioning the remain widgets.

当我从顶部移除窗口小部件时，底部窗口小部件将自动移至顶部，看起来不错.但是，当我从左侧删除窗口小部件时，右侧窗口小部件不会移到左侧吗?

When I remove a widget from top the bottom widget will automatically get moved to top its looks good. But when I remove a widget from left the right widget not gets moved to left?

推荐答案

最后我解决了这个问题

<div class="gridster">
    <ul>
      <li data-row="1" data-col="1" data-sizex="2" data-sizey="2">0<span class="removeWidget">X</span></li>
      <li data-row="1" data-col="3" data-sizex="1" data-sizey="2">1<span class="removeWidget">X</span></li>
      <li data-row="1" data-col="4" data-sizex="1" data-sizey="1">2<span class="removeWidget">X</span></li>
      <li data-row="3" data-col="2" data-sizex="3" data-sizey="1">3<span class="removeWidget">X</span></li>
      <li data-row="4" data-col="1" data-sizex="1" data-sizey="1">4<span class="removeWidget">X</span></li>
      <li data-row="3" data-col="1" data-sizex="1" data-sizey="1">5<span class="removeWidget">X</span></li>
      <li data-row="4" data-col="2" data-sizex="1" data-sizey="1">6<span class="removeWidget">X</span></li>
      <li data-row="5" data-col="2" data-sizex="1" data-sizey="1">7<span class="removeWidget">X</span></li>
      <li data-row="4" data-col="4" data-sizex="1" data-sizey="1">8<span class="removeWidget">X</span></li>
      <li data-row="1" data-col="5" data-sizex="1" data-sizey="3">9<span class="removeWidget">X</span></li>
    </ul>
  </div>
