show div based on Dropdown selection in mvc4?

Question

Hi my j query code is not working.

My View 

 

<div class="col-sm-4">

<div class="form-group">

@Html.LabelFor(model => model.POVisit, new { @class = "control- label",id="POVisit" })

@Html.DropDownList("POVisitID", "Select")

</div>

</div>

<div id ="OrderReceivedYesNo">

<div class="col-sm-4">

<div class="form-group">

@Html.LabelFor(model => model.OrderReceived, new { @class = "control-label" })

@Html.RadioButton("OrderReceived", 1) Yes

@Html.RadioButton("OrderReceived", 0) No

</div>

</div>

</div>

 

My jquery code 

 

 

$(document).ready(function () {

$("#OrderReceivedYesNo").hide();

});

$(document).ready(function () {

$("#POVisit").on('change', function () {

if (this.value == "Order")

{

$("#OrderReceivedYesNo").show();

}

});

});

 

The above code is not working. The POVisit Dropdown have 7 values which is directly fetch from Database. Initially i hide the OrderReceived radio buttons. If i select the "Order" value in POVisit DropDown it needs to show the "OrderReceivedYesNo" div. But the above code that show code is not working.

And my DateTimePicker is also not working.

$("#Date").datepicker({

maxDate: "+0D",

changeMonth: true,

changeYear: true,

yearRange: "-100:+0",

dateFormat: "M/dd/yy",

});

<input type="text" id="Date" class = "form-control date" />

<span class="error">Valid order date required (ex. MM-dd-yyyy)</span>

</div>

</div>

</div>
