To incorporate a script object into the DOM, you can establish a function like this:
<script type="text/javascript">
function loadMyCustomJavaScript() {
var script = document.createElement("script");
script.src = "http://www.example.org/my.js";
script.type = "text/javascript";
document.getElementsByTagName("head")[0].appendChild(script);
}
</script>
You can then utilize it through google.setOnLoadCallback
<script src="http://www.google.com/jsapi?key=ABCDEFG" type="text/javascript"></script>
<script type="text/javascript">
google.load("jquery", "1");
google.setOnLoadCallback(loadMyCustomJavaScript);
</script>
Alternatively, if you wish to link it with a specific Google library via a callback method:
<script src="http://www.google.com/jsapi?key=ABCDEFG" type="text/javascript"></script>
<script type="text/javascript">
google.load("maps", "2");
google.load("search", "1", {"callback" : loadMyCustomJavaScript});
</script>
Further update: You might consider using jQuery.getScript, which allows a callback function for externally loaded JavaScript code. As stated in HubLog: Google, jQuery and plugin loading, employing window.setTimeout could be necessary to postpone function execution until the script(s) are eval'd.
Given that jQuery and its plugins likely load asynchronously, utilizing unobtrusive JavaScript may be preferable over embedding jQuery/plugin functions directly within the HTML markup.
