I want to do some client side validation using javascript in ASP.NET page.
I tried using
<script src="../../../JS/Registration.js" language="javascript" type="text/javascript" />
but its not working. Please help.

ScriptManager control can also be used to reference javascript files. One catch is that the ScriptManager control needs to be place inside the form tag. I myself prefer ScriptManager control and generally place it just above the closing form tag.
<asp:ScriptManager ID="sm" runat="server">
<Scripts>
<asp:ScriptReference Path="~/Scripts/yourscript.min.js" />
</Scripts>
</asp:ScriptManager>
add like
<head runat="server">
<script src="Registration.js" type="text/javascript"></script>
</head>
OR can add in code behind.
Page.ClientScript.RegisterClientScriptInclude("Registration", ResolveUrl("~/js/Registration.js"));
I assume that you are using MasterPage so within your master page you should have
<head runat="server">
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
</head>
And within any of your pages based on that MasterPage add this
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<script src="js/yourscript.js" type="text/javascript"></script>
</asp:Content>
If your page is deeply pathed or might move around and your JS script is at "~/JS/Registration.js" of your web folder, you can try the following:
<script src='<%=ResolveClientUrl("~/JS/Registration.js") %>'
type="text/javascript"></script>
Use Fiddler to see what is happening. Then change the path accordingly. You will probably find you get a 404 error and the path is wrong.
