Data validation

Sep 7 2017 3:26 AM

I am building a web application. I want to make sure that the entered amount should be below available amount. I am not able to do this validation, I am using entityframework 6, MVC and C#. Is it possible to do this with $("#Id").change(function (). I would we glad if somebody help me to resolve this.

Thank you

My view has

<div class="form-group">
@Html.LabelFor(model => model.Amount, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Amount, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Amount, "", new { @class = "text-danger" })
</div>
</div>

Controller has

//code for checking balance ...........................
[HttpGet]
[OutputCache(Duration = 0)]
public JsonResult CheckAmount(Decimal Amount)
{
Decimal amt = Amount;
long MaxTrNo = db.CashBalances.Max(m => m.TRRecordNo);
var v = db.CashBalances.Where(m => m.TRRecordNo == MaxTrNo).Select(m => m.CashInHand);
decimal MaxCashInHand = v.FirstOrDefault().Value;
string msg = "";
if (MaxCashInHand <= amt)
{msg = "Sufficient fund"; }
else
{msg = "InSufficient fund"; }
return Json(msg, JsonRequestBehavior.AllowGet);

and Script in View has the following

<head>
<script src="~/Scripts/jquery-3.1.1.js"></script>
<script type="text/javascript">
$(function () {
$("#Amount").change(function () {
//????????????
//??????????????
});
});
</script>
