How to change the default icon in Easyui Treegrid

Under normal circumstances, treegrid icons are in the form of default folders and files, as shown below:

We can add iconCls to the json text to change the default icon , for example in the sample:

{"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"}
]}

Then modify icon.css and place the icons to be used in the specified folder.

Normally, after making such modifications, treegrid can display the icons you designed.

If the icon you set cannot be displayed at this time, you can check the order in which icon.css and easyui.css are introduced on the page. Make sure that easyui.css is in In front, icon.css is in the back. Otherwise, the style in easyui.css will overwrite icon.css and still display the default icon.

The following is an introduction to the jQuery EasyUI treegrid addition, deletion, modification and check code

<script type="text/javascript">

if (value){

return s;
} else {
return &#39;&#39;;
