创建树形网格(TreeGrid)
<table id="test" title="Folder Browser" class="easyui-treegrid" style="width:700px;height:300px"
data-options="
url: 'data/treegrid_data.json',
method: 'get',
rownumbers: true,
idField: 'id',
treeField: 'name',
loadFilter: myLoadFilter
<thead>
<th field="name" width="220">Name</th>
<th field="size" width="100" align="right">Size</th>
<th field="date" width="150">Modified Date</th>
</thead>
</table>
为了放置加载子节点,我们需要为每个节点重命名 'children' 属性。
正如下面的代码所示,'children' 属性重命名为 'children1'。
当展开一个节点时,我们调用 'append' 方法来加载它的子节点数据。
'loadFilter' 代码
function myLoadFilter(data,parentId){
function setData(){
var todo = [];
for(var i=0; i<data.length; i++){
todo.push(data[i]);
while(todo.length){
var node = todo.shift();
if (node.children){
node.state = 'closed';
node.children1 = node.children;
node.children = undefined;
todo = todo.concat(node.children1);
setData(data);
var tg = $(this);
var opts = tg.treegrid('options');
opts.onBeforeExpand = function(row){
if (row.children1){
tg.treegrid('append',{
parent: row[opts.idField],
data: row.children1
row.children1 = undefined;
tg.treegrid('expand', row[opts.idField]);
return row.children1 == undefined;
return data;
