Create the Redirection Drop-Down List Box

To create the redirection drop-down list box, follow these steps:

  1. Start FrontPage, and then open your site.
  2. On the File menu, point to New, and then click Blank page in the New task pane.
  3. On the View menu, click Page(if it is not already selected), and then click Code at the bottom of the page.
  4. Insert the following code sample between the <body> and </body> tags on your page:
    <h4 align="center">Where Do You Want to Go Today?</h4> <center> <form> <p><select name="section" size="1" language="javascript" onChange="gotoPage(this.selectedIndex);"> <option selected>Where do you want to go today?</option> <option>- - - - - - - - - - - - - - - - -</option> <option>Microsoft Home Page</option> <option>MSN Home Page</option> </select></p> </form> </center> <script language="JavaScript"> <!-- function gotoPage(varItem) { switch(varItem) { case 0: window.parent.self.status="Goes Nowhere"; break; case 1: window.parent.self.status="Goes Nowhere"; break; case 2: window.location="http://www.microsoft.com"; break; case 3: window.location="http://www.msn.com"; break;}} // --> </script>

    Note This code sample uses the window.location property to load new pages. If you are using a frameset, the new page is displayed in the current frame. If you want, you can use the window.open method to load the page and then specify a target frame. For example, to display the Microsoft® home page in a full screen, use the following JavaScript code:

    case 2: window.open("http://www.microsoft.com", target="_top"); break;

    Note– You may receive an error message, or the page may not display correctly if you copy the examples directly from this article and paste them into FrontPage. The angle brackets (< and >) may appear as HTML code. To work around this behavior, first paste the code sample into a blank document in Notepad, and then copy the code sample from the document in Notepad to your page in FrontPage. To do so, follow these steps:

    1. Copy the code sample from step 4.
    2. Start Notepad, and then open a blank document.
    3. On the Edit menu, click Paste.
    4. On the Edit menu, click Select All.
    5. On the Edit menu, click Copy.
    6. In FrontPage, position the insertion point on a blank line immediately below the <body> tag where you want to insert the JavaScript code.
    7. On the Edit menu, click Paste.
  5. On the File menu, click Save.
  6. In the Save As dialog box, specify a file name and a location where you want to save the page, and then click Save.
  7. On the File menu, point to Preview in Browser, and then click the Web browser that you want to use to preview the page.
