grid与tree行数据获取
获取管理对象
var treeManager = $(
"#roleTree").ligerGetTreeManager();
var gridManager = $(
"#listgrid").ligerGetGridManager();
获取多行选中记录
var gridData = gridManager.getCheckedRows();
var treeData = treeManager.getChecked();
这样获取的是集合对象[]，即使实际上只选中了行，获取数据也是gridData[0].attr
获取单行选中记录
var gridData = gridManager.getSelectedRow();
var treeData = treeManager.getSelected();
获取整个对象的所有数据(选中+未选中)
var allGridArray = gridManager.getData();
var allTreeArray = treeManager.getData();
