Easyui Treegrid改变默认图标的方法
lyxc_0101 人气:0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。
