创建简单的文本编辑器 (javascript)

Question

新手上路，请多包涵

我想用 Javascript 创建一个简单的文本编辑器。我面临的挑战是：我的文本编辑器上方的按钮应该根据 DOM 的内容进行调整。例如：如果光标位于我的文本编辑器中的“ul”标签内，则应仅显示按钮“li”。

我已经创建了一个“内容可编辑的 div”，但我不知道接下来要看哪里。有人可以帮我一些想法吗？如果我可以在现有的 JS 文本编辑器的帮助下做到这一点，请说。

 <html>
<head>
    <style>
        #textEditor {
            border: 1px solid black; display:block; width: 300px; height: 200px;
        }
    </style>
    <script>
        var options = ['ul','div'];
        var subOptions = {
            'ul':['li'],
            'div':['div','span', 'p']
        };
    </script>

</head>
<body>
    <div id="textEditor" contenteditable="true"></div>
</body>
</html>

我使用唯一的 javascript 创建了一个简单的富文本编辑器。特别是我为我的 powerBI 自定义视觉对象创建了这个。您可以在任何项目中使用它。

     function chooseColor(){
      var mycolor = document.getElementById("myColor").value;
      document.execCommand('foreColor', false, mycolor);
    }

    function changeFont(){
      var myFont = document.getElementById("input-font").value;
      document.execCommand('fontName', false, myFont);
    }

    function changeSize(){
      var mysize = document.getElementById("fontSize").value;
      document.execCommand('fontSize', false, mysize);
    }

    function checkDiv(){
      var editorText = document.getElementById("editor1").innerHTML;
      if(editorText === ''){
        document.getElementById("editor1").style.border = '5px solid red';
      }
    }

    function removeBorder(){
      document.getElementById("editor1").style.border = '1px solid transparent';
    }

 body {
    font: 400 16px/1.4 'serif';
    }
