这是我从数据库中检索到的对象:
@RequestMapping("/category/edit/{id}")
@org.springframework.transaction.annotation.Transactional
public ModelAndView displayCategoryList(@PathVariable("id")Integer id){
ModelAndView mav = new ModelAndView("category-form");
List<CatFeatGroup> catFeatGroupList = catFeatGroupService.findGroupsForCategory(id);
mav.addObject("catFeatGroupList",catFeatGroupList);
return mav;
}
这是我的表格。
<form class="form-horizontal">
<div th:each="catFeatGroup,status : ${catFeatGroupList}" class="form-group">
<label>Position</label><input th:field="catFeatGroupList[${status.index}].position" th:value="${catFeatGroup.position}" />
<label>Name</label> <input name="catGroupList[${status.index}].name" th:value="${catFeatGroup.name}" />
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
我需要使用 th:field
来绑定(bind)该对象,但是出现了这个错误:
Could not parse as expression: "catFeatGroupList[${status.index}].position"
最佳答案
像这样添加“__”符号
<form class="form-horizontal">
<div th:each="catFeatGroup,status : ${catFeatGroupList}" class="form-group">
<label>Position</label><input th:field="*{catFeatGroupList[__${status.index}__].position}" th:value="${catFeatGroup.position}" />
<label>Name</label> <input data-th-name="*{catFeatGroupList[__${status.index}__].name}" th:value="${catFeatGroup.name}" />
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
