<script type="text/javascript">
$('#jTweetsAnywhereSample').jTweetsAnywhere({
    showTweetBox:{
        counter: true,
        width: 380,
        height: 65,
        label: '<span style="color: #A4A4A4">What\'s happening?</span>',
        defaultContent: '#jTweetsAnywhere',
        onTweet: function(textTweet, htmlTweet){
            alert('You tweeted: ' + textTweet);
        }
    }
});
</script>

Here's the code to create the customized Tweet Box. The Box can be configured by the showTweetBox attribute. For any value omitted, a default value will be used.
