Validate value of Dropdownlist (jquery)

[Kurt Kluth]

Currently have 2 dropdown lists (month & year) that I would like to validate they are not blank and verify that they aren't for a future date.  I am unable to get the value via jquery.  Suggestions?


<script type="text/javascript">

    var oWnd;

    //<![CDATA[

    function daysInMonth(month, year) {

        return new Date(year, month, 0).getDate();

    }

 

    function openRadWin(InMode) {

        //Removes the scroll bars from the Parent Window

        removeScrollbars();

 

        var MonthInput = $find("<%= _NewMonth.ClientID %>");

        var YearInput = $find("<%= _newYear.ClientID %>");

        var newVal = $('#_newYear').val();

        var dropFind = $find("<%= _NewMonth.ClientID %>");

        var valueFind = dropFind.get_value();

 

        alert(valueFind);

}

</script>

New statement cycle date <strong>(mm/dd/yyyy)</strong>:
<telerik:RadDropDownList ID="_NewMonth" runat="server" DefaultMessage="Select a Month">
    <Items>
        <telerik:DropDownListItem runat="server" Selected="false" Text="January" Value="1" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="February" Value="2" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="March" Value="3" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="April" Value="4" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="May" Value="5" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="June" Value="6" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="July" Value="7" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="August" Value="8" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="September" Value="9" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="October" Value="10" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="November" Value="11" />
        <telerik:DropDownListItem runat="server" Selected="false" Text="December" Value="12" />
    </Items>
</telerik:RadDropDownList>
<telerik:RadDropDownList ID="_NewYear" runat="server">
</telerik:RadDropDownList>

Hi Kurt Kluth,

Please try the following JavaScript which works fine at my end.

JavaScript:

<script type="text/javascript">
    function openRadWin(InMode) {
        var newVal = $('#_NewYear').val();
        var valueFind = $find("<%=_NewMonth.ClientID %>").get_selectedItem().get_value();
        if (newVal != "" && valueFind != "") {
            var date = new Date();
            var month = date.getMonth() + 1;
            var year = date.getFullYear();
            if (newVal > year)
                alert("validation fails");
            if (newVal == year) {
                if (valueFind > month)
                    alert("validation fails");
            }
            else
                alert("validation success");
        }
    }
</script>

Hope this will helps you.
Thanks,
Shinu.
