已经基本了解了dojo中tree的使用,现在做一些比较经典的应用。 先截个图,展示一下总体的目标: 大致就是左边是一棵树,右边是一棵树,然后用户可以方便的选择。 好了,现在分步
已经基本了解了dojo中tree的使用,现在做一些比较经典的应用。
先截个图,展示一下总体的目标:
大致就是左边是一棵树,右边是一棵树,然后用户可以方便的选择。
好了,现在分步来实现,先是这个框架,代码:
<!DOCTYPE HTML> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'treeTest.jsp' starting page</title> <link rel="stylesheet" type="text/css" href="js/dijit/themes/claro/claro.css"> <link rel="stylesheet" type="text/css" href="css/main.css"> </head> <body class="claro"> <button type="button" id="treeBtn" data-dojo-type="dijit/form/Button">tree测试</button> <form data-dojo-type="dijit/form/Form"> <div data-dojo-type="dijit/Dialog" class="selectDia" id="selectDia" title="终端划分"> <table> <tr> <td> <fieldset> <legend>未选中</legend> <div class="leftTree" id="leftTree"></div> </fieldset> </td> <td> <button class="toRightBtn" id="toRightBtn" type="button" data-dojo-type="dijit/form/Button">--></button> <br/> <br/> <button class="toLeftBtn" id="toLeftBtn"type="button" data-dojo-type="dijit/form/Button"><--</button> </td> <td> <fieldset> <legend>已选中</legend> <div class="rightTree" id="rightTree"></div> </fieldset> </td> </tr> </table> <div class="actionBar"> <button type="submit" data-dojo-type="dijit/form/Button">确定</button> <button type="button" id="cancelBtn" data-dojo-type="dijit/form/Button">取消</button> </div> </div> </form> <script type="text/javascript" src="js/dojo/dojo.js" data-dojo-config="parseOnLoad:false"></script> <script type="text/javascript"> require([ "dojo/parser", "dijit/registry", "dojo/on", "dijit/form/Button", "dijit/Tree", "dojo/domReady!" ], function(parser, registry, on, Button, Tree){ parser.parse().then(function(){ registry.byId("treeBtn").on("click", function(){ registry.byId("selectDia").show(); }); registry.byId("cancelBtn").on("click", function(){ registry.byId("selectDia").hide(); }); }); }); </script> </body> </html>
css代码:
保存为main.css
html,body{ margin:0 0; padding:0 0; } .leftTree{ width:230px; height:350px; border:1px solid #d3d3d3; } .rightTree{ width:230px; height:350px; border:1px solid #d3d3d3; } .actionBar{ text-align: right; background-color: #efefef; border-top: 1px solid #d3d3d3; margin: 10px -8px -10px; padding: 3px 10px 3px 7px; } .clear{ clear: both; }到此,框架已经搭起来了,下面将开始重头戏,cbtree,第三方扩展dojo的tree,使其带有checkbox,这样就方便多了,下回分解。
