Normally, 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:

&#8203;{"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 easyui.css is first and icon.css is last. Otherwise, the style in easyui.css will overwrite icon.css and still display the default icon.

Let me introduce to you the jQuery EasyUI treegrid addition, deletion, modification and check code

<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;
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 style="margin:10px 0;">
<a href="javascript：void(0)" disabled="disabled" class="easyui-linkbutton actionbtn" onclick="save()">Save</a>
<a href="javascript：void(0)" disabled="disabled" class="easyui-linkbutton actionbtn" onclick="cancel()">Cancel</a>
</div>
