Question

我试图创建一个函数，如果用户没有足够的积分，则无法扣减积分。我正在使用MVC来做到这一点。它将提示用户他们的分数不足以从问题中得到答案。回答

您可以通过Jquery进行Ajax Get函数来获取人物的分数

然后您可以检查一个人的点数是否大于10 .. 否则显示警报..

示例：

  if (confirm("Are you sure you want an answer? It will deduct 10 points.")) {                
    $.ajax({
        type: "post",
        url: "@Url.Content("~/")API/PointsTransaction/PointsTransactAnswer",
        contentType: "application/json; charset=utf-8",               
        success: function(obj) {

        // let make * Ppoints * is person points that we have gitten from Ajax
    if (Ppoints > 10 ) {
     // show the answer
    }else {
    alert("oops, you don't have enough points to show this answer")
    }

        }
    });   
    }

还有..使用按钮时，您可以使用Jquery进行功能。

  $(document).ready(function() {
  $('#answer').click(function() {
  // what to do if the button clicked
  })
  })

希望我能帮助您！和我的英语不好对不起。

hi @ rod在您的ajax调用中，您可以获得用户的积分，并且在成功时，如果积分大于10，您可以做其他事情

< a href = "#" class = "btn"  id = "answer" onclick = "return Confirm()" > Answer < /a> 



    < script type = "text/javascript" >
                 "use strict";
                 function Confirm() {

                 var text;
                         if (confirm("Are you sure you want an answer? It will deduct 10 points.")) {
                 $.ajax({
                 type: "post",
                         url: "@Url.Content("~/")API/PointsTransaction / PointsTransactAnswer",
                         contentType: "application/json; charset=utf-8",
                         success: function(obj) {
                         if (obj.points > 10){
                             // do whatever you want if points of user is grater than 10 .
                         } else{
                             // if points of user is less than 10 show message.
                             alert('Oops. points is less than 10 . ');
                         }

                         }
                 });
                         text = "";
                         return true;
                 } else {
                 return false;
                 }


                 }

如果用户的积分不足，则提醒用户
