Easyui Treegrid改变默认图标的方法

普通情况下，treegrid的图标是默认的文件夹与文件的形式，如下图：

​​​我们可以在json文本中加入iconCls来改变默认图标，例如样例中：

​{"total":7,"rows":[ {"id":1,"name":"All Tasks","begin":"3/4/2010","end":"3/20/2010","progress":60,"iconCls":"icon-ok"}, {"id":2,"name":"Designing","begin":"3/4/2010","end":"3/10/2010","progress":100,"_parentId":1,"state":"closed"}, {"id":21,"name":"Database","persons":2,"begin":"3/4/2010","end":"3/6/2010","progress":100,"_parentId":2}, {"id":22,"name":"UML","persons":1,"begin":"3/7/2010","end":"3/8/2010","progress":100,"_parentId":2}, {"id":23,"name":"Export Document","persons":1,"begin":"3/9/2010","end":"3/10/2010","progress":100,"_parentId":2}, {"id":3,"name":"Coding","persons":2,"begin":"3/11/2010","end":"3/18/2010","progress":80}, {"id":4,"name":"Testing","persons":1,"begin":"3/19/2010","end":"3/20/2010","progress":20} ],"footer":[ {"name":"Total Persons:","persons":7,"iconCls":"icon-sum"} ]}

然后修改icon.css以及将要用到的图标放在指定的文件夹。

通常情况下，讲过这样的修改，treegrid就可以显示出你自己设计的图标了。

​如果此时还不能显示出你设定的图标，可以查看一下页面中引入icon.css以及easyui.css的顺序，要保证easyui.css在前，icon.css在后。否则，easyui.css中的样式就会将icon.css覆盖点，依旧显示默认图标。

下面给大家介绍jQuery EasyUI treegrid 增删改查代码

<script type="text/javascript"> function formatProgress(value){ if (value){ var s = '<div>' + '<div>' + value + '%' + '</div>' '</div>'; return s; } else { return ''; } } var editingId; function deleteRow(){ if (editingId != undefined){ $('#tg').treegrid('select', editingId); return; } var row = $('#tg').treegrid('getSelected'); if (row){ editingId = row.id $('#tg').treegrid('remove', editingId); $('#tg').treegrid('reloadFooter'); } $(".actionbtn").toggleClass("l-btn-disabled"); } function edit(){ if (editingId != undefined){ $('#tg').treegrid('select', editingId); return; } var row = $('#tg').treegrid('getSelected'); if (row){ editingId = row.id $('#tg').treegrid('beginEdit', editingId); } $(".actionbtn").toggleClass("l-btn-disabled"); } function insert(){ if (editingId != undefined){ $('#tg').treegrid('select', editingId); return; } /**/ var rows = $('#tg').treegrid('getChildren'); editingId = rows.length+1; var row = null; var _data = {"id":editingId,"name":"new name","persons":0,"begin":"3/19/2010","end":"3/20/2010","progress":10}; var _parentId = 0; var row = $('#tg').treegrid('getSelected'); if (row){ $('#tg').treegrid('expand',row.id); _parentId = row.id; }else{ var root = $('#tg').treegrid('getRoot'); _parentId = null; } $('#tg').treegrid('append',{ parent: _parentId, // 这里指定父级标识就可以了 data: [_data] }); $('#tg').treegrid('beginEdit',_data.id); $(".actionbtn").toggleClass("l-btn-disabled"); } function save(){ if (editingId != undefined){ var t = $('#tg'); t.treegrid('endEdit', editingId); editingId = undefined; var persons = 0; var rows = t.treegrid('getChildren'); for(var i=0; i<rows.length; i++){ var p = parseInt(rows[i].persons); if (!isNaN(p)){ persons += p; } } var frow = t.treegrid('getFooterRows')[0]; frow.persons = persons; t.treegrid('reloadFooter'); $(".actionbtn").toggleClass("l-btn-disabled"); } } function cancel(){ if (editingId != undefined){ $('#tg').treegrid('cancelEdit', editingId); editingId = undefined; } $(".actionbtn").toggleClass("l-btn-disabled"); } </script> <div> <a href="https://www.jb51.net/javascript：void(0)" disabled="disabled">Save</a> <a href="https://www.jb51.net/javascript：void(0)" disabled="disabled">Cancel</a> </div>
