一.效果。如下图中,各途中可相互拖拉,右下角可删除。注意图1和图2对比区别

图2
二.源码详解
html源码

js源码
$(function(){ $(‘.btn.remove‘).click(function(){ if(confirm("确定要删除页面吗?")) { $(this).parent().detach(); } }); var dropable = $(‘#dropzone‘).droppable({ activeClass : ‘active‘, hoverClass : ‘hover‘, accept : ":not(.ui-sortable-helper)" }); dropable.sortable({ items : ‘.drop-item‘, sort : function() { $(this).removeClass("active"); } }); $(‘#report_page_save_btn‘).click(function(){ save(); }); $(‘#report_page_def_btn‘).click(function(){ if(confirm("确定要恢复页面数据吗?")) { set_def(); } }); });
使用其他第三方js结构如下。其实就只有使用了jquery-ui
另一个简单案例

jquery-ui-处理拖动位置Droppable,Draggable
