Ways of getting Dropdown list Selected Values.

There are 2 ways to get DropDownList selected values through Javascript.

Suppose,we have a DropDownList as below:-

<asp:DropDownList ID="ddl_name_list" runat="server">
   <asp:ListItem Text="Vishal" Value="1">Vishal</asp:ListItem>
   <asp:ListItem Text="Rajesh" Value="2">Rajesh</asp:ListItem>
</asp:DropDownList>

1st way:-

var ddl = document.getElementById('<%=ddl_name_list.ClientID%>');
var value = ddl.options[ddl.selectedIndex].value;
alert(value);

2nd way:-

var value = document.getElementById("<%= ddl_name_list.ClientID %>").value;
alert(value);
