我正在使用php / mysql数据加载树面板。 但是当我点击加载树子节点时,它也没有显示父节点的名称。它获取记录并在控制台中显示json响应,但无法在树中加载子节点。
父节点的Json响应:
[{"0":"1","id":"1","1":"Settings","name":"Settings","leaf":false,"cls":"folder"},{"0":"2","id":"2","1":"Data","name":"Data","leaf":false,"cls":"folder"},{"0":"3","id":"3","1":"Reports","name":"Reports","leaf":false,"cls":"folder"},{"0":"4","id":"4","1":"Campaigns","name":"Campaigns","leaf":false,"cls":"folder"}]
子节点的Json响应
[{"0":"1","id":"1","1":"Home","text":"Home","leaf":false,"cls":"folder"},{"0":"2","id":"2","1":"Log out","text":"Log out","leaf":false,"cls":"folder"},{"0":"47","id":"47","1":"Campaign Reports","text":"Campaign Reports","leaf":false,"cls":"folder"},{"0":"49","id":"49","1":"Supplier Stats","text":"Supplier Stats","leaf":false,"cls":"folder"},{"0":"50","id":"50","1":"Label Piechart","text":"Label Piechart","leaf":false,"cls":"folder"},{"0":"51","id":"51","1":"Country Piechart","text":"Country Piechart","leaf":false,"cls":"folder"},{"0":"52","id":"52","1":"Supplier Piechart","text":"Supplier Piechart","leaf":false,"cls":"folder"},{"0":"53","id":"53","1":"Over All piechart","text":"Over All piechart","leaf":false,"cls":"folder"}]
js文件:
var store = Ext.create('Ext.data.TreeStore', {
autoLoad : true,

id : 'root_node',
