我有一个包含功能列表的jsp页面.在控制器中,我从数据库中获取此列表,并将其传递给jsp.
I have a jsp page with list of functions. Here in controller I get this list from database and pass it to jsp.
@RequestMapping(value = "/functionlist", method = RequestMethod.GET) public ModelAndView functionList(Model model) throws Exception { ModelAndView mv = new ModelAndView("functionList"); mv.addObject("functionList", getFunctionsFromDB()); return mv; }在我的jsp页面中,我使用此功能列表创建表
In my jsp page I create table using this list of functions
<table id="table"> <thead> <tr> <th></th> <th>Name</th> <th>Action</th> </tr> </thead> <tbody> <c:choose> <c:when test="${not empty functionList}"> <c:forEach var="function" items="${functionList}"> <tr> <td><input name="id" value="${function.id}" hidden></td> <td>${function.name}</td> <td> <input type="checkbox" id="${function.id}" value="${function.action}"></td> </tr> </c:forEach> </c:when> </c:choose> </tbody> </table> <button type="submit" name="save">Save</button>我还将功能ID赋予复选框ID.
I also give function id to checkbox id.
我的Function实体如下
My Function entity is the following
public class Function { private Integer id; private String name; private Boolean action; ... }我想按保存"按钮并进入控制器"/functionlist/save"我的复选框值列表.
I want to press button Save and get in controller "/functionlist/save" my list of checkbox values.
推荐答案尝试将这样的form添加到您的jsp页面
Try to add form like this to your jsp page
<form:form id="yourForm" action="/functionlist/save" method="POST" modelAttribute="functionList"> <c:forEach items="${functionList}" varStatus="status" var="function"> <tr> <td>${function.name}</td> <td> <form:checkbox path="functionList[${status.index}].action"/> </td> </tr> </c:forEach> <input type="submit" value="submit" /> </form:form>在Controller中,您应该有这样的方法
and in Controller you should have a method like this
@RequestMapping(value = { "/functionlist/save" }, method = RequestMethod.POST) public String savePerson(@ModelAttribute("functionList")List<Function> functionList) { // process your list }如果这不起作用,则可以尝试包装列表.
If this does not work, you can try to wrap you list.
public class FunctionListWrapper { private List<Function> functionList; public FunctionListWrapper() { this.functionList = new ArrayList<Function>(); } public List<Function> getFunctionList() { return functionList; } public void setFunctionList(List<Function> functionList) { this.functionList = functionList; } public void add(Function function) { this.functionList.add(function); } }在控制器中,而不是通过列表,而是通过包装器
in controller instead of passing list, pass wrapper
FunctionListWrapper functionListWrapper=new FunctionListWrapper(); functionListWrapper.setFunctionList(userService.getFunctionList()); mv.addObject("functionListWrapper", functionListWrapper);有关更多详细信息,请查看以下问题:问题1 和问题2
