Question: I want to use jQuery in my ASP.NET 3.5 website that uses master pages and content pages. How do I do document ready() functions for the child pages for those that will use jQuery ? Where do I put the code?

I figured the jQuery declarations should go in the master page, but don't know how to make sure any jQuery calls go into the HEAD of the resolved page.

Answer: 
Just put a content placeholder in the master's head section, and then write page-specific scripts withing the asp:Content tags of your pages.

**Master**

```
<%@ Master Language="C#" %>
<html>
    <head>
        <script type="text/javascript" src="scripts/jquery-1.4.3.js"></script>
        <asp:contentplaceholder id="LocalScripts" runat="server" />
    </head>
    <body>
    </body>
</html>

```

**Page**

```
<%@ Page Language="C#" MasterPageFile="~/Master1.master" 
         AutoEventWireup="true" Title="MyTitle"  %>
<asp:Content ID="Content1" Runat="Server" ContentPlaceHolderID="LocalScripts" >
    <script type="text/javascript"> 
        $(document).ready(function () {
           // some local script logic here
        });
    </script>
</asp:Content>

```
You should be able to just use something like this:

**In child page** (*I don't think it matters greatly WHERE it is put in the page*):

```
<script type="text/javascript">
    $(document).ready(function () {
        //Do work here
    });
</script>

```

as long as you have included the necessary jQuery files (libraries and plug-ins) in your master page.
