EXTJS 遇到的函数定义问题，请高人指点，谢谢
function callback_${param.cmpId}(cmp){ var tree = new Ext.tree.TreePanel({ title: '组织机构', region: 'west', collapsible: true, autoScroll : false, rootVisible : true, autoScroll : true, width: 210, bodyStyle: 'background:white', margins: '0 5 0 0', root : new Ext.tree.AsyncTreeNode({ text: '组织机构', expanded: true, id: 0 }), loader: new Ext.tree.TreeLoader({ dataUrl: baseURL+'/orgAction!loadOrgTree.page', baseParams: {} }), listeners: { click: function(node) { var treeNodeId = node.attributes.id; organisationStore.load({params:{orgId: treeNodeId}}); }, scope: this } }); var organisationStore = new Ext.data.Store({ proxy: new Ext.data.HttpProxy({ url: baseURL + '/userAction!searchUser.page', method: 'POST' }), reader: new Ext.data.JsonReader({ root: 'data', idProperty: 'Id', totalProperty: 'totalCount', successProperty: 'success' }, [ {name: 'Id'}, {name: 'UserName'}, {name: 'UserRealName'}, {name: 'IsActive'} ]) }); var gridTbr = new Ext.Toolbar({ items: [ {text: '新增',iconCls:'addIcon', handler: function(){ openNewWin(grid); } }, {text: '修改',iconCls:'edit1Icon', handler: function(){ openEidtWin(grid); } }, {text: '删除',iconCls:'deleteIcon', handler: function(){ delRecord(grid); } },'-', {text: '锁定',iconCls:'lockIcon', handler: function(){ unactiveuser(grid); } }, {text: '解锁',iconCls:'lockOpen', handler: function(){ activeuser(grid); } },'-', {text: '所属部门',iconCls:'award_star_bronze_3', handler: function(){ openEidtPart(grid); } }, {text: '所属角色',iconCls:'award_star_bronze_3', handler: function(){ openEidtWin(grid); } } ]}); var sm = new Ext.grid.CheckboxSelectionModel(); var grid = new Ext.grid.GridPanel({ region: 'center', tbar: gridTbr, store: organisationStore, sm: sm, columns: [ sm, {header: '编号',dataIndex: 'Id'}, {header: '用户姓名',dataIndex: 'UserRealName'}, {header: '用户帐号',dataIndex: 'UserName'}, {header: '状态',dataIndex: 'IsActive',renderer: function(value){ return value == '1' ?
