问题描述

 <   script     src   =  jquery-1.3 .2.min.js    type   =  text / javascript >   <   / script  >  
 <   script     type   =  text / javascript >  
 $（document）.ready（function（）{
 $（＃AmountId）。change（function（）{
 var a = parseInt（$（'#TotaltobePaid'）。val（），10）; 
 var b = parseInt（$（'＃AmountId'）。val（），10）; 
 $（'form'）。submit（）; 
 var result = 0; 
 a = isNaN（a）？ 0：a; 
 b = isNan（b）？ 0：b; 
 if（a> 0&& b> 0）
 result = a  -  b; 
 $（＃Balance）。text（+ result）; 
 
}）; 
 
}）; 

继承人我的HTML代码





@ Html.LabelFor（model => model.TotaltobePaid）





@ Html.EditorFor（model => model.TotaltobePaid，new {name =Totaltobepaid，id =TotaltobePaid}）







@ Html.LabelFor（model => model.AmountPaid）





@ Html.EditorFor（model => model.AmountPaid ，new {name =Amount，id =AmountId}）

< button class =btn btn-primaryid =AmountButton> Go< / button>





@ Html.LabelFor（model => model.Balance）





@ Html.EditorFor（model => model.Balance，new {name =Balance，id =Balance}）

解决方案

（document）.ready（function（）{

（＃AmountId）。change（function（）{
var a = parseInt（

（'＃要taltobePaid'）。val（），10）;
var b = parseInt（

<script src="jquery-1.3.2.min.js" type="text/javascript"></script>
  <script type="text/javascript">
      $(document).ready(function () {
                   $("#AmountId").change(function () {
              var a = parseInt($('#TotaltobePaid').val(), 10);
              var b = parseInt($('#AmountId').val(), 10);
              $('form').submit();
              var result=0;
              a = isNaN(a) ? 0 : a;
              b = isNan(b) ? 0 : b;
              if (a > 0 && b > 0)
                  result = a - b;
              $("#Balance").text(+result);

          });

      });

heres my html code


@Html.LabelFor(model => model.TotaltobePaid)


@Html.EditorFor(model => model.TotaltobePaid, new { name = "Totaltobepaid", id = "TotaltobePaid" })



@Html.LabelFor(model => model.AmountPaid)


@Html.EditorFor(model => model.AmountPaid, new { name = "Amount", id = "AmountId" })
<button class="btn btn-primary" id="AmountButton">Go</button>


@Html.LabelFor(model => model.Balance)


@Html.EditorFor(model => model.Balance, new { name = "Balance", id = "Balance" })

解决方案

(document).ready(function () {

("#AmountId").change(function () { var a = parseInt(

('#TotaltobePaid').val(), 10); var b = parseInt(
