Question

我想并排制作两个textareas，它们共用一个边框。然后我们可以拖动边框并改变它们的宽度，同时保持它们的宽度总和不变。换句话说，它就像JSBin中的面板。

有谁知道如何实现这个目标？

PS：这是制作两个固定文本区域的代码：

<!DOCTYPE html>
<html>
<head>
  <title>JS Bin</title>
</head>
<body>
  <textarea name="t1"></textarea>
  <textarea name="t2"></textarea>   
</body>
</html>

编辑1：以下代码来自JSBin的index.html。但我不知道它如何设法实现共享边界：

  <div id="panelswaiting">
    <div class="code stretch html panel">
      <div role="menubar" class="label menu" tabindex="0"><span class="name"><strong><a href="#htmlprocessors" role="menuitem" class="fake-dropdown button-dropdown">Processor</a></strong></span><div class="dropdown" id="htmlprocessors">
          <div role="menu" aria-hidden="true" class="dropdownmenu processorSelector" data-type="html">
            <a role="menuitemradio" aria-checked="true" href="#html" data-label="HTML">HTML</a>

            <a href="#convert">Convert to HTML</a>
          </div>
        </div>
      </div>
      <div class="editbox">
        <textarea aria-label="HTML Code Panel" spellcheck="false" autocapitalize="none" autocorrect="off" id="html"></textarea>
      </div>
    </div>
    <div class="code stretch javascript panel">
      <div role="menubar" class="label menu" tabindex="0"><span class="name"><strong><a role="menuitem" class="fake-dropdown button-dropdown" href="#javascriptprocessors">Processor</a></strong></span>
        <div class="dropdown" id="javascriptprocessors">
          <div role="menu" aria-hidden="true" class="dropdownmenu processorSelector" data-type="javascript">

            <a role="menuitem" href="#convert">Convert to JavaScript</a>
          </div>
        </div>
      </div>
      <div class="editbox">
        <textarea aria-label="JavaScript Code Panel" spellcheck="false" autocapitalize="none" autocorrect="off" id="javascript"></textarea>
      </div>
    </div>
    ...
  </div>

编辑2：

根据Ankit vadariya的回答，我做了a minimum case ...只剩下一件事：如何确保min-width的{{1}}？它目前似乎不起作用......

一种方法是设置.panel-right的{{1}}，但如果我们查看JSBin，则每个面板都没有max-width的限制，而.panel-left。max-width。 ..

Here is the your solution

希望它对你有用。

$(".panel-left").resizable({
   handleSelector: ".splitter",
   resizeHeight: false
 });

 $(".panel-top").resizable({
   handleSelector: ".splitter-horizontal",
   resizeWidth: false
 });

  overflow: auto;
}

.page-container {
  margin: 20px;

/* horizontal panel*/

.panel-container {
  display: flex;

Answer 2

我能看到这样做的唯一方法是使用像JavaScript这样的东西，实时分析一个宽度，让另一个加到100％。

让两个textareas并排共享一个灵活的边界
