GAS：是否可以在服务器端构建html

Question

我正在处理具有多个输入的复杂synamic表单。我认为在服务器端构建并在客户端注入HTML服务表单可能更容易。我有：

  function buildOptionList(id, options) {

    //  http://jsfiddle.net/4pwvg/

    var document = '<div id="myDiv">Append here</div>';

  //  var myDiv = document.getElementById("myDiv");

    //Create array of options to be added
    //  var array = ["Volvo","Saab","Mercades","Audi"];
    var array = options;


    //Create and append select list
    var selectList = document.createElement("select");
    selectList.setAttribute("id", id);
    //  myDiv.appendChild(selectList);

    //Create and append the options
    for (var i = 0; i < array.length; i++) {
      var option = document.createElement("option");
      option.setAttribute("value", array[i]);
      option.text = array[i];
      selectList.appendChild(option);
    }
    Logger.log(selectList)
    return selectList;

  }

但是当我跑步时，我得到了：

TypeError: Cannot find function createElement in object <div id="myDiv">Append here</div>

所以我想知道服务器端GAS是否有能力构建HTML？
