删除实例 view层调用Controller中Action删除 MVC AJAX JSON

View层

<a onclick="Del('@item.ID')" href="javascript:void(0)">删除</a>

 <script type="text/javascript" language="javascript">
    function Del(id) {
        var warning = "您确定要删除吗？";
        var flag = true;
        //调用controller中的方法，判断是否允许删除
         if (confirm(warning)) {
            $.ajax({
                type: 'post',
                async: false, //是否异步
                 url: '/Controller/AllowDelete', //  '/Controller/Action'
                data: {id:id},//{参数：参数值}
                success:function(data){
                    if(data=="true")
                    {
                        flag=true;
                    }
                    else
                    {
                        flag=false;
                    }
                }
            })
            if(flag==false){
                alert("禁止删除！");
            }
        }
        else{
            flag=false;
        }
        //判断成功后直接删除
        if (flag) { //  '/Controller/Action'
            $.get("/Controller/Delete", { id: id }, function (data) {
                if (data.result) {
                    window.location.href = window.location.href;
                }
                else {
                    alert("删除失败！");
                }
            })
        }
    }
</script>

Controller 层

//删除
        public ActionResult Delete(int id)
        {
            return Json(new { result = BLL.Delete(id) }, JsonRequestBehavior.AllowGet);
        }

        //判断能否删除
        [HttpPost]
        public ActionResult AllowDelete(int id)
        {
            return Content(BLL.AllowDelete(id).ToString().ToLower());//ToLower() 转化为小写字母
        }
