    button-ext grey" style="">
    <span class="sf-button-ext__content"><ng-
    transclude>Apply</ng-transclude></span>
    </button><!-- end ngIf: 
    popup.buttons.OK --> <button sf-name="popup-cancel" class="popup-footer-

Answer 1

在以下行的帮助下，您将获得text的{​​{1}}

sf-button-ext__content

尝试以下javascript，

document.getElementsByClassName('sf-button-ext__content')[0].textContent;

window.onload = function() {
  var element = document.getElementsByClassName('sf-button-ext__content');
  console.log(element[0].textContent);
}
