项目中要用到easyui，使用也有几年时间了，刚开始使用还不错，毕竟只是简单的增删改查数据，不过到后面越来越觉得easyui不如extjs了，好多复杂一点的问题，easyui表现就力不从心了，题外话就讲到这吧，下面看看这个问题是如何解决的：
$(function () { $.fn.zTree.init($("#tree"), setting); initTopoConfig(); showTopo(0); stage.wheelZoom = 0.85; // 设置鼠标缩放比例 $("#undo").hide(); }); //初始化拓扑图配置 function initTopoConfig() { $("#center").append(''); var canvas = document.getElementById('canvas'); $("#main").panel({ onResize: function (w, h) { canvas.width = w-30; canvas.height = h - 20; } }); stage = new JTopo.Stage(canvas); scene = new JTopo.Scene(stage); setScene(); }
<body onselectstart="return false" class="easyui-layout" style="margin: -1px;"> <div id="myposition" data-options="region:'west',split:true,title:'交换机列表'" style=" 250px;"> <ul id="tree" class="ztree"> </ul> </div> <div id="center" data-options="region:'center',border:false,fit:true"> <div id="main" fit="true"> <div id="tool" style="background-color: #f5f5f5; border-bottom: 1px solid #ddd"> <table> <tr> <td> <a href="#" class="easyui-linkbutton" iconcls="icon-add" plain="true" onclick="addRouter()"> 添加路由</a> </td> <td> <a href="#" class="easyui-linkbutton" iconcls="icon-add" plain="true" onclick="addChildrenTopo()"> 添加子图</a> </td> <td> <a href="#" class="easyui-linkbutton" iconcls="icon-save" plain="true" onclick="save()"> 保存</a> </td> <td> <a href="#" class="easyui-linkbutton" iconcls="icon-zoomin" plain="true" onclick="zoomout()"> 放大</a> </td> <td> <a href="#" class="easyui-linkbutton" iconcls="icon-zoomout" plain="true" onclick="zoomin()"> 缩小</a> </td> <td> <a href="#" class="easyui-linkbutton" iconcls="icon-resize" plain="true" onclick="fitContent()"> 自适应</a> </td> <td> <a href="javascript:void(0)" class="easyui-linkbutton" plain="true" style="text-align: center" data-options="iconCls:'icon-reload'" onclick="javascript:location.reload();">刷新页面</a> </td> <td id="undo"> <a href="#" class="easyui-linkbutton" iconcls="icon-undo" plain="true" onclick="before()"> 返回上一级</a> </td> </tr> </table> </div> <canvas id="canvas"></canvas> </div>
总结：要把id为tool的div放到main里面，要不然就会出现自适应不成功的问题。
