Question

我想将视图中的json数据发送到asp.net mvc中的控制器。但是数据是空的。

package wad.hellolist;

import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloListController {

    private List<String> list;

    public HelloListController() {
        this.list = new ArrayList<>();
        this.list.add("Hello list!");
    }

    @RequestMapping("/")
    public String home(Model model, @RequestParam(required = false) String content) {
        if (content != null && !content.trim().isEmpty()) {
            this.list.add(content.trim());
        }

        model.addAttribute("list", list);
        return "index";

    }
    // Method below needs something.
    @RequestMapping(value = "/", method = RequestMethod.POST)
    public void deleteList() {
            this.list.clear();  
    }
}

控制器代码：数据：电子邮件，用户名，密码。数据为空。调试结果：email = null，username = null，password = null

 $(document).ready(function () {
    $('#btnSignUp').click(function () {

        var email = ('#txtEmail').val();
        var username = ('#txtUsername').val()
        var password= ('#txtSifre').val();



        $.ajax({
            url: '/User/SignUp',
            data: { email: email, username: username, password: password},
            datatype: 'Json',
            type: 'Post'

        }).done(function () {
            $('#success').show(500);
        })

    })
})

Json数据发送为null
