原话这一层权限能改成不需要勾选么就当个分组用 最终的效果图如下 解决思路
1.判断哪些是父节点给父节点添加disabled属性——this.permissionList是数据源
通过递归的方法来判断是否是父节点。
filterMenuList(arr, item) {arr.forEach((child) {if (child.children child.children.length 0) {child.disabled true;child this.filterMenuList(child.children, item);}});return item;
},使用递归方法
this.permissionList.forEach((item) {if (item.permissions item.permissions.length 0) {item this.filterMenuList(item.permissions, item);}
});通过上面的方法可以给父节点添加disabled为true的属性了。
2.通过css样式来处理disabled的父节点
/deep/li.ant-tree-treenode-disabled span.ant-tree-checkbox.ant-tree-checkbox-disabled {display: none !important;
}
/deep/.ant-treeli.ant-tree-treenode-disabled .ant-tree-node-content-wrapper span {color: rgba(0, 0, 0, 0.65) !important;
}3.完整代码如下
