easyui treegrid checkbox 无法清除

[jees5555]

现象
1.第一次进入能够自动匹配 javabean的 Boolean checked 字段
2.第二次无法清除 checkbox ,并且第一次选中的row也无法手动unchecked
3.savepermisson 方法无法获取roleid

源代码 permission.js

checkroleid = roleid;
checkrolename = rolename;
// 清空数据
$('#permissiondg').treegrid({
data : null
});
// 清除选中状态
$('#permissiondg').treegrid('clearChecked'); //这句有问题！！！！
// 重新加载数据

$('#permissiondg').treegrid('clearChecked'); //这句有问题！！！！ 放到treegrid的onLoadSuccess中执行，要不ajax都没返回数据你清除不了

[jees5555]

这样的确是可以清除了,可是我想在选择不同的角色之后加载新的treegrid，如果不在新的加载之前清除的话 那么原来checked的字段会一直check下去 datagrid 是可以先clear 再加载新的，而不只是在 onloadsuccess里才有效

[jees5555]

没有满意回复，但分还是给吧

[qq_36201508]

我现在也遇到这种情况一直没找到原因，请问你解决了吗？

[qq_21302299]

改为这样： ------------------------------- // 清除选中状态 $('#permissiondg').treegrid('clearChecked'); //这句有问题！！！！ // 清空数据 $('#permissiondg').treegrid({ data : null });
