Previewing pages in browsers



    Preview in a browser

    You can preview a page in a browser at any time; you don’t have to upload it to a web server first. When you preview a page, all browser-related functions should work, including JavaScript behaviors, document‑relative and absolute links, ActiveX® controls, and Netscape Navigator plug‑ins, provided that you installed the required plug‑ins or ActiveX controls in your browsers.

    Before previewing a document, save the document; otherwise, the browser does not display your most recent changes.

    1. Do one of the following to preview the page:

      • Select File > Preview In Browser, and then select one of the listed browsers.

        Note: If no browsers are listed, select Edit > Preferences or Dreamweaver > Preferences (Macintosh), and then select the Preview In Browser category on the left to select a browser.

      • Press F12 (Windows) or Option+F12 (Macintosh) to display the current document in the primary browser.

      • Press Control+F12 (Windows) or Command+F12 (Macintosh) to display the current document in the secondary browser.

    2. Click links and test content in your page.
      If you use Internet Explorer on a Windows XP computer with Service Pack 2 installed, the browser may display a message that tells you it has restricted the file from showing active content. You can fix this problem by including Mark of the Web code in the file.
      Note: Content linked with a site root-relative path does not appear when you preview documents in a local browser unless you specify a testing server, or select the Preview Using Temporary File option in Edit > Preferences > Preview In Browser. This is because browsers don’t recognize site roots—servers do.
      To preview content linked with root-relative paths, put the file on a remote server, and then select File > Preview In Browser to view it.
    3. Close the page in the browser when you finish testing.

    Set browser preview preferences

    You can set preferences for the browser to use when previewing a site and define default primary and secondary browsers.

    1. Select File > Preview In Browser > Edit Browser List.
    2. To add a browser to the list, click the Plus (+) button, complete the Add Browser dialog box, and then click OK.
    3. To delete a browser from the list, select the browser, and then click the Minus (-) button.
    4. To change settings for a selected browser, click the Edit button, make changes in the Edit Browser dialog box, and then click OK.
    5. Select the Primary Browser or the Secondary Browser option to specify whether the selected browser is the primary or secondary browser.

      F12 (Windows) or Option+F12 (Macintosh) opens the primary browser; Control+F12 (Windows) or Command+F12 (Macintosh) opens the secondary browser.

    6. Select Preview Using Temporary File to create a temporary copy for previewing and server debugging. (Deselect this option if you want to update the document directly.)

    Preview active content in Internet Explorer (Windows)

    If you preview a document that contains active content in Internet Explorer after installing the Windows XP Service Pack 2 update, the browser does not show active content. You can fix this problem by inserting Mark of the Web code in your document.

    Internet Explorer blocks active content and scripting that tries to run in the Local Machine zone. For security reasons, Microsoft increased the restrictions on what can run in this zone by default. Mark of the Web code tells the browser to run active content in another zone, in this case, the Internet zone. For more information, see TechNote 19578 on the Adobe website at www.adobe.com/go/19578.

    Insert Mark of the Web code

     With your document open in Dreamweaver, select Commands > Insert Mark Of The Web.

    Dreamweaver inserts the following line in your code:

    <!-- saved from url=(0014)about:internet -->

    The line tells the browser to bypass the Local Machine zone and run the active content in the Internet zone.

    Remove Mark of the Web code

    1. In Dreamweaver, open the document containing the Mark of the Web code.
    2. Select Commands > Remove Mark Of The Web.
