我使用以下代码在选择之间切换。但是我使用的脚本很简单，所以我需要在 HTML 中编写更多内容来隐藏其他选项卡，正如您在代码中看到的那样。帮助我使用脚本来简化 HTML 部分。
function showStuff(id) {
var id1 = id.replace(/[^\w\s]/gi, '');
document.getElementById(id).style.display = "block";
document.getElementById(id1).classList.add('active');
}
function hideStuff(id) {
var id1 = id.replace(/[^\w\s]/gi, '');
document.getElementById(id).style.display = "none";
document.getElementById(id1).classList.remove('active');
}
div.container {
padding: 7px;
height: 100%;
width: 80%;
margin: 0 auto;
}
<body>
<div class="container">
<ol>
<li id="tabs1" onclick="showStuff('tabs-1'); hideStuff('tabs-2'); hideStuff('tabs-3');hideStuff('tabs-4'); hideStuff('tabs-5');hideStuff('tabs-6'); hideStuff('tabs-7');hideStuff('tabs-8'); hideStuff('tabs-9');hideStuff('tabs-10'); hideStuff('tabs-11');hideStuff('tabs-12'); hideStuff('tabs-13');hideStuff('tabs-14'); hideStuff('tabs-15');hideStuff('tabs-16');hideStuff('tabs-17');hideStuff('tabs-18');hideStuff('tabs-19');">selet A</li>
<li id="tabs2" onclick="hideStuff('tabs-1'); showStuff('tabs-2'); hideStuff('tabs-3');hideStuff('tabs-4'); hideStuff('tabs-5');hideStuff('tabs-6'); hideStuff('tabs-7');hideStuff('tabs-8'); hideStuff('tabs-9');hideStuff('tabs-10'); hideStuff('tabs-11');hideStuff('tabs-12'); hideStuff('tabs-13');hideStuff('tabs-14'); hideStuff('tabs-15');hideStuff('tabs-16');hideStuff('tabs-17');hideStuff('tabs-18');hideStuff('tabs-19');">select B</li>
</ol>
</div>
<div style="display: table-cell; width: 1%; "></div>
<div id="tabs-1">
<h1>A is selected</h1>
<textarea onclick="this.focus(); this.select();" readonly="readonly">
this is example and A is selected
</textarea>
</div>
<div id="tabs-2" style="display : none">
<h1>B is selected:</h1>
<textarea onclick="this.focus();this.select()" readonly="readonly">
Another example for b is selected
</textarea></div>
</body>
此外，我需要从文本文件（存储在服务器中）或通过任何其他方式获取 textarea 内容，以便我可以避免在代码中添加冗长的部分。有没有办法用文本文件替换textarea？
