This tutorial illustrates how to check if a plugin exists or if plugin has been already loaded using jQuery. This is particularly useful if you are writing your jQuery code that depends on that plugin.
if(jQuery().plugin_name) {
// plugin exists
} else {
// plugin not loaded
}

Here’s a tutorial on how to get the value of a checked or selected radio button out of a group of radio buttons:
...
<input type="radio" name="sample" value="1" />
<input type="radio" name="sample" value="2" checked="checked" />
<input type="radio" name="sample" value="3" />
...
//javascript code
<script type="text/javascript">
<!--
// displays the selected radio button in an alert box
alert($('input[name=sample]:checked').val())
-->
</script>
