Question

我尝试使用required =＆＃34; true＆＃34;和th：required =＆＃34; required＆＃34;并且仅使用必需（因为我使用百里香叶时抛出错误），添加空值值=＆＃34;＆＃34;但仍然无法正常工作。我尝试添加值=＆＃34;哑＆＃34;和价值=＆＃34;＆＃34;对于第二个选项标签，同样......没有工作并尝试使用bootstrap验证器。当我提交表单时，我有一个弹出窗口，如果我按OK，则提交表单。我正在使用chrome，我有另一种形式，我正在使用输入+必需，并且它正在工作。任何帮助将不胜感激。谢谢！

<form th:action="@{/appointment/create}" method="post" id="appointmentForm">
<div class="form-group">
                <label for="location">Alege institutia:</label>

                <select class="form-control" required="required" 
                th:value="${appointment.institutie}"name="institutie" 
                id="institutie">

                 <option value="" disabled="disabled" selected="selected" > 
                 -- alege institutia --</option>
                 <option th:each="institutie : ${institutieList}"  
               th:text="${institutie.numeInstitutie}" ></option>

               </select>
</div></form>


            var confirm = function() {
            bootbox.confirm({
                title : "Confirmare programare",
                message : "Doriti sa creeati programarea?",
                buttons : {
                    cancel : {
                        label : '<i class="fa fa-times"></i> Nu'
                    },
                    confirm : {
                        label : '<i class="fa fa-check"></i> Da'
                    }
                },
                callback : function(result) {
                    if (result == true) {
                        $('#appointmentForm').submit();
                    } else {
                        console.log("Confirmare anulata.");
                    }
                }
            });
        };

UPDATE 控制器负责填充＆＃34; institutieList＆＃34;

@RequestMapping(value="/create", method=RequestMethod.GET)
public String createAppointmentPost(Model model, @ModelAttribute("city") 
City city, @ModelAttribute("agency") Agency agency, Principal principal){

    User user = userService.findByUsername(principal.getName());
    Appointment appointment=new Appointment();
    model.addAttribute("appointment", appointment);
    model.addAttribute("dateString", "");
    model.addAttribute("cities", cityService.findAll());    
    model.addAttribute("institutieList", instituteService.findAll());
    model.addAttribute("myFiles", userService.listAllUploadedFiles(user));
    return "appointment";
}

更新2：问题在于提交按钮，我忘了输入=＆＃34;提交＆＃34;。

Answer 1

正确使用所需的isn不需要=＆＃34; true＆＃34;但只需要，如：

<select class="form-control" required 
            th:value="${appointment.institutie}"name="institutie" 
            id="institutie">

标签选择所需的属性不起作用
