JavaScript 将一个函数的结果显示为HTML

要把一个函数的结果显示为HTML，你可以使用-

document.getElementById().innerHTML.

示例

以下是代码 –

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Document</title>
</head>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<body>
   <div>
      <input type="text">
      <br>
      <input type="text">
      <br>
      <input type="radio">
      <br>
      <input type="text">
      <br>
      <input type="radio">
      <br>
   </div>
   <br>
   <span id='totalNumberOfTextBox'></span>
</body>
<script>
   total_number_of_check_box();
   function total_number_of_check_box() {
      var inputObj = document.getElementsByTagName("input"),
      counter = 0;
      for (var i = 0; i < inputObj.length; i++) {
         if (inputObj[i].type == "text") {
            counter++;
         }
      }
      document.getElementById('totalNumberOfTextBox').innerHTML = "Total
      Number of text box is=" + counter;
   }
</script>
</html>

要运行上述程序，请保存文件名 anyName.html(index.html)。在该文件上点击右键，在VS代码编辑器中选择 “用实时服务器打开 “选项。
