Javascript Button Pressing

I revised your post to put the HTML code in a Code Block.

We cannot properly test your HTML code snippet because it is incomplete and non-functional.

But here is my best un-tested guess, which can serve as a starting point for you:

var scriptResults = 'TBD';
var btn = document.querySelector('button.btn.ui-draggable[type="roll"]');
if (btn) {
  btn.click();
  scriptResults = 'OK';
} else { scriptResults = '[ERROR]  button.btn.ui-draggable was NOT found.'; }

scriptResults;
