这篇文章主要介绍了Easyui Treegrid改变默认图标的方法的相关资料,需要的朋友可以参考下

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 style="width:100%;border:1px solid #ccc">' +

'<div style="width:' + value + '%;background:#cc0000;color:#fff">' + value + '%' + '</div>'

'</div>';

return s;

} else {

return '';

}

}

var editingId;

if (editingId != undefined){

$('#tg').treegrid('select', editingId);
