Change Submit Button text on a Marketo Landing Page Form

gistfile1.html

<script type="text/javascript">
// Add this code in a "HTML" block in the Marketo Landing Page Editor.

// Use jQuery.noConflict just in case.
if ( typeof $jQ == 'undefined' ) { var $jQ = jQuery.noConflict(); }

// Declare your Submit Button Text; example: .val('Register for Webinar')
$jQ(document).ready(function() {
  $jQ('#mktFrmSubmit').val('... your text here...');
})
  
</script>

Thank you to Eric Hollebone for providing the basis for this code.
