删除以“data-wf-”开头的属性

var elements = document.querySelectorAll('[data-wf-]');

for (var i = 0; i < elements.length; i++) {
  var attributes = elements[i].attributes;
  
  for (var j = 0; j < attributes.length; j++) {
    var attributeName = attributes[j].name;
    
    if (attributeName.startsWith('data-wf-')) {
      elements[i].removeAttribute(attributeName);
    }
  }
}
