extjs 3.31 TreeGrid는 json을 TreeGrid_extjs로 로드하는 정적 페이지를 구현합니다.

var root = new Ext.tree .TreeNode({
text: 'Root node',
expanded: true
})
tree.setRootNode(root)
var node =
nodes.children = mydata;/*TreeGrid의 json 데이터 [{…},{…}]*/
function appendChild(node, o) {
if (o.children != null && o.children .length > 0) {
for (var a = 0; a < o.children.length; a ) {
var n = new Ext.tree.TreeNode({
task:o. children [a].task,
기간:o.children[a].duration,
user:o.children[a].user,
iconCls:o.children[a].iconCls
});
node.appendChild(n);
appendChild(n, o.children[a])
}
}
}
appendChild(루트, 노드) ;
