2024-04-30 03:39:04 425

要将div分为三列，请使用columnCount属性。设置列数并除以div。

示例

您可以尝试运行以下代码以返回使用JavaScript将元素划分为的列数-

<!DOCTYPE html>
<html>
   <body>
      <p>Click below to create 4 columns</p>
      <button onclick="display()">Columns</button>
      <div id="myID">
         This is demo text. This is demo text. This is demo text. This is demo text.
         This is demo text. This is demo text. This is demo text. This is demo text.
         This is demo text. This is demo text. This is demo text. This is demo text.
         This is demo text. This is demo text. This is demo text. This is demo text.
         This is demo text. This is demo text. This is demo text. This is demo text.
         This is demo text. This is demo text. This is demo text. This is demo text.
         This is demo text. This is demo text. This is demo text. This is demo text.
      </div>
      <script>
         function display() {
            document.getElementById("myID").style.columnCount = "4";
         }
      </script>
   </body>
</html>
