Dart：如何以编程方式将标题添加到 'pop-up' window？

Question

当我的主页上有一个按钮 clicked/tapped 但不知道如何显示标题时，我设法显示了一个以编程方式创建的带有一些按钮的 'pop up' 页面。我该怎么做，还有我应该在 HEAD 中设置的其他项目吗？我是新手

btnToolsClicked(Event e) { 

  var content = 'Choose an Action <b>(Work In Progress)</b>'
    '<div id="menu-btns" class="radio-btns">'
      '<input id="B1" type="radio" name="radio-btn">'
        '<label id="lblB1" class="radiobutton-label" for="B1">&nbspExtract Thermal Data.</label><br>'
      '<input id="B2" type="radio" name="radio-btn" >'
        '<label id="lblB2" class="radiobutton-label" for="B2">&nbspCopy Data to USB drive.</label><br>'
      '<input id="BClose" type="radio" name="radio-btn" >'
        '<label id="lblClose" class="radiobutton-label" for="&nbspBClose">Close</label>'
    '</div>';


  JsObject w =
  context.callMethod("open",["","MsgWindow","width=640,height=480,top=100,left=100"]);

  JsObject doc = w['document'];
  doc['head']['innerHtML'] = '<title>Tools Menu</title>'; // FAILS
  doc['body']['innerHTML'] = content;
}

Answer 1

还没有测试过，但我希望它能工作：

  JsObject doc = w['document'];
  doc['title'] = 'Tools Menu';
