这是在我的

$(‘#newTicketSubmit’).click(function () { var jsonData = [ {‘topic’:$(‘#inputTopic’).val()}, {‘priority’:$(‘#inputPriority option:selected’).val()}, {‘assigned’:$(‘#inputAssign option:selected’).val()}, {‘text’:$(‘#inputText’).val()}, {‘solved’:0}, {‘date’:‘No date set’} ]; $.ajax({ |
这就是我的 javascript 文件的样子。它确实调用了服务器。但我不是 100% 确定我是否正确地做所有事情

public class Ticket {
public Ticket() @Id @NotEmpty @NotEmpty @NotNull @NotNull @NotNull |
最后这里是我的
我希望我的项目了解的是,当我从 javascript 应用程序发送内容时。然后服务器将了解如何从该 json 数据创建 Ticket 类。如果我理解正确。这应该是可能的。但我以某种方式做错了什么。
任何可以带我走上正确道路的帮助都非常受欢迎

好的,所以我昨天找到了解决问题的方法。问题是我对 Json data
的实现

2 3 4 5 6 7 8 |
var jsonData = {
‘topic’:$(‘#inputTopic’).val(), ‘priority’:parseInt($(‘#inputPriority option:selected’).val()), ‘assigned’:parseInt($(‘#inputAssign option:selected’).val()), ‘text’:$(‘#inputText’).val(), ‘solved’:0, ‘date’:‘No date set’ }; |
这是一个在 javascript 中工作的 Json 数据示例。
