Thymeleaf在前台下拉列表获取后台传的值
后台添加代码:
/** * 新增机构 */ @GetMapping("/add") public String add(ModelMap mmap) { List<Scholar> scholars = scholarService.selectScholarListName(); mmap.put("scholars",scholars); return "module/institution/add"; }
后台修改代码:
/** * 修改机构 */ @GetMapping("/edit/{id}") public String edit(@PathVariable("id") String id, ModelMap mmap) { Institution institution = institutionService.selectInstitutionById(id); List<Scholar> scholars = scholarService.selectScholarListName(); mmap.put("scholars",scholars); mmap.put("institution", institution); return "module/institution/edit"; }
前台代码添加:
<div class="form-group"> <label class="col-sm-3 control-label">主要研究人员:</label> <div class="col-sm-8" > <!--<input id="majorResearcher" name="majorResearcher" class="form-control" type="hidden">--> <!--<select name="title" id="title" class="form-control m-b"> <option th:each="scholars : ${scholars.title}" th:text="${scholars.title}" th:value="${scholars.title}" ></option> </select>--> <select class="form-control" name="majorResearcher"> <option value=""> -- 主要研究人员 -- </option> <option th:each="scholars:${scholars}" th:value="${scholars.title}" th:text="${scholars.title}"></option> </select> </div> </div>
前台代码回显:
<div class="form-group"> <label class="col-sm-3 control-label">主要研究人员:</label> <div class="col-sm-8"> <!-- <input id="majorResearcher" name="majorResearcher" th:field="*{majorResearcher}" class="form-control" type="text" >--> <select class="form-control" name="majorResearcher"> <option value=""> -- 主要研究人员 -- </option> <option th:each="scholars:${scholars}" th:value="${scholars.title}" th:text="${scholars.title}" th:field="*{majorResearcher}"></option> </select> </div> </div>
