获取其中包含特定元素的元素作为子元素，而不使用jquery

function getElementsWithSpecificChild(parentId, childSelector) {
  var parent = document.getElementById(parentId);
  var children = parent.querySelectorAll('*');
  var result = [];

  for (var i = 0; i < children.length; i++) {
    var child = children[i];
    if (child.querySelector(childSelector)) {
      result.push(child);
    }
  }

  return result;
}

var elements = getElementsWithSpecificChild('parentElementId', '.specificChildElement');
console.log(elements);
