tag 'select', field 'list', name 'department.id':

本文主要是介绍tag 'select', field 'list', name 'department.id':，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

下拉选择框：

<s:select class="form-control" list="#allDeparts" name="departmentId"  listKey="id" listValue="name" headerKey="-1" headerValue="--请选择--"/>

今天这个问题花了几个小时，原本快要放弃了，最后单点调试，逐个的把数据输出来才发现问题所在

1.在加载页面前，需要加载数据，导致了departs集合中为空

2.在迭代加入departs集合中出现了问题，主要是输出是也是it.next（），加入集合中数据过少,在最后的迭代判断的时出错

System.out.println("----------"+it.next());
if(it.next().isChild()){
System.out.println("======="+it.next());
}

这篇关于tag 'select', field 'list', name 'department.id':的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
