Bagaimana untuk menukar ikon lalai dalam Easyui Treegrid_jquery

Biasanya, ikon treegrid adalah dalam bentuk folder dan fail lalai, seperti yang ditunjukkan di bawah:

​​​Kita boleh menambah iconCls pada teks json untuk menukar ikon lalai, contohnya dalam sampel:

​{"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"}
]}

Kemudian ubah suai icon.css dan letakkan ikon untuk digunakan dalam folder yang ditentukan.

Biasanya, selepas membuat pengubahsuaian sedemikian, treegrid boleh memaparkan ikon yang anda reka.

Jika ikon yang anda tetapkan tidak dapat dipaparkan pada masa ini, anda boleh menyemak susunan ikon.css dan easyui.css diperkenalkan pada halaman Pastikan easyui.css adalah yang pertama dan icon.css yang terakhir. Jika tidak, gaya dalam easyui.css akan menimpa icon.css dan masih memaparkan ikon lalai.
