FP: Sample DHTML to Compare Two Passwords

View products that this article applies to.

Summary

In Microsoft FrontPage, when you use the HTML password text box to input data on a form, the text is not displayed to the browser. For example, in Microsoft Internet Explorer, asterisks appear in place of each character that you type. This can make it impossible to verify if the information entered is correct.

In addition, in FrontPage, the built-in form validation does not allow you to compare two text boxes to allow you to enter the same password twice to confirm a match.

You can use Dynamic HTML (DHTML) to compare the information typed in two password text boxes before you submit a form. This article provides sample DHTML code that checks the values in two password fields, displays a message box if the fields do not match, and prevents you from submitting the form results if they don't match.

NOTE: This article includes custom DHTML that may not be available in all browsers. For more information about compatibility with other browsers, click Microsoft FrontPage Help on the Help menu, type compatibility in the Office Assistant or the Answer Wizard, and then click Search to view the topic.

  1. In FrontPage, open a Web on a Web server.
  2. Open a new page.
  3. Switch to HTML view and remove all the existing HTML.
  4. Type the following HTML code:
    <html>
<head>
<title>Password Test</title>
<script language="javascript">
<!--
function checkMe()
{
  if (document.myForm.PWD1.value == document.myForm.PWD2.value)
  {
    document.myForm.PWD.value=document.myForm.PWD1.value;
    document.myForm.submit();
  }
  else
    alert("Passwords do not match!");
}
//-->
</script>
</head>

<body>

<p>Please enter your user name and password.</p>

<form method="POST" name="myForm">
  <input type="hidden" name="PWD">
  <table border="1">
    <tr>
      <td>Name</td>
      <td><input type="text" name="UID" size="20"></td>
    </tr>
    <tr>
      <td>Password</td>
      <td><input type="password" name="PWD1" size="20"></td>
    </tr>
    <tr>
      <td>Repeat Password</td>
      <td><input type="password" name="PWD2" size="20"></td>
    </tr>
    <tr>
      <td colspan="2" align="center">
        <input type="button" onClick="checkMe()" value="Submit">
        <input type="reset" value="Reset">
      </td>
    </tr>
  </table>
</form>
</body>
</html>
  5. Switch back to Normal View.

    You should see a form with three text boxes.
  6. Right-click the form and then click Form Properties on the menu that appears.
  7. In the Form Properties dialog box, click Send to, and then click Options.
