Make sure that your jQuery loading and browser up to date...
Simplify the page to something like below. Get that working. Add back
your complexity afterwards:
<span class="EncodedDescriptionField">Q29va2llcyBvbmU=</span>
<script>
$(".EncodedDescriptionField").each( function(index, element ){
var hereWeAre = $(this).text();
alert(hereWeAre);
var decodedString = atob(hereWeAre);
console.log(decodedString);
});
</script>
