# ProductCart and jQuery

## How it is loaded

ProductCart leverages the popular [jQuery](http://jquery.com/) JavaScript library to perform client-side tasks such as displaying information in a modal window, handling the user experience on One Page Checkout, and more.

jQuery is loaded in the ProductCart storefront as follows:

- the file ”*header.asp*” in the pc folder includes ”*inc\_header.asp*”
- the file ”*inc\_header*” includes ”*inc\_jquery.asp*”
- ”*inc\_jquery.asp*” loads the CSS and JavaScript as follows (as of January, 2011)

  

```

<!--INCLUDE JQUERY - START -->
<%
private const scJQuery="1"
%>
<link type="text/css" href="../includes/jquery/themes/redmond/jquery-ui-1.7.2.custom.css" rel="stylesheet" />
<%
user_agent = request.servervariables("HTTP_USER_AGENT")
if Instr(ucase(user_agent),"CHROME")>0 then
	%>
    <link type="text/css" rel="stylesheet" href="onepagecheckout.css" />
    <link type="text/css" rel="stylesheet" href="onepagecheckoutGoogle.css" />
<% else %>
	<link type="text/css" rel="stylesheet" href="onepagecheckout.css" />
<% end if %>
<script type="text/javascript" src="../includes/jquery/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="../includes/jquery/jquery-ui-1.7.2.custom.min.js"></script>
<script type="text/javascript" src="../includes/jquery/jquery.validate.min.OPC.js"></script>
<script type="text/javascript" src="../includes/jquery/jquery.bgiframe.pack.js"></script>
<script type="text/javascript" src="../includes/jquery/jquery.form.js"></script>
<!--INCLUDE JQUERY - END -->
```

 

## Potential conflicts

If you load jQuery independently of ProductCart (e.g. you load it in header.asp as part of your Web site interface), there could be some conflicts that result in JavaScript errors.

For example, some customers have reported problems on One Page Checkout (cannot move passed Billing panel).

We strongly recommend that you do not load 2 instances of jQuery. You should be able to safely remove the additional include statements in your Web site design and just rely on the fact that ProductCart loads jQuery already.
