Question

index.cshtml

<script type="text/javascript">
    function OnSuccessComment(data) {
        alert(data.resultMessage);
    }
</script>

@using (Ajax.BeginForm(new AjaxOptions
{
    Url = Url.Action("AddCommentAjax"),
    OnSuccess = "OnSuccessComment",
    HttpMethod = "POST"
}))
{
    @Html.TextArea("comment")
    <input type="submit" value="Добавить комментарий" />
}

HomeController.cs

namespace WebApplication12.Controllers
{
    public class HomeController : Controller
    {
        private static List<string> _comments = new List<string>();
        public ActionResult Index()
        {
            return View(_comments);
        }
        [HttpPost]
        public ActionResult AddComment(string comment)
        {
            //необходимые действия
            return View();
        }

        [HttpPost]
        public ActionResult AddCommentAjax(string comment)
        {
            //необходимые действия
            return Json(new { resultMessage = "Ваш комментарий добавлен успешно!" });
        }

    }
}

问题是按钮点击不会调用函数AddCommentAjax。如何解决？有什么问题？

Answer 1

@using (Ajax.BeginForm("AddCommentAjax", "Home", new AjaxOptions { OnSuccess = "OnSuccessComment",
    HttpMethod = "POST"
}))

尝试这样的事情

不要忘记包含javascript文件：

<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>

MVC中的AJAX不会调用联结
