Adobe Dreamweaver CS5 : Working with Multimedia and Online Tools - Checking for Plug-ins

1/6/2013 6:17:34 PM

Use the Check Plugin action to send visitors to different pages depending on whether they have the specified plug-in installed. For example, you might want visitors to go to one page if they have Shockwave and another page if they do not. The Check Plugins action is an excellent tool for making your visitor’s experience a pleasant one.

Use the Check Plug-in Action

1. Open the Web page you want to use.

2. Select an object (for an element) or click the <body> tag in the tag selector (for an entire page).

3. Open the Behaviors panel.

4. Click the Plus (+) button, and then click Check Plugin from the Actions menu.

5. Select a plug-in from the Plugin list arrow, or type the exact name of the plug-in in the adjacent text box.

6. Configure Check Plug-in using the following options:

If Found, Go To URL. Enter a URL for visitors who have the plug-in.

Note

To cause visitors with the plug-in to stay on the same page, leave this field blank.
Otherwise, Go To URL. Enter an alternative URL for visitors who don’t have the plug-in.

Note

To cause visitors without the plug-in to stay on the same page, leave this field blank.
Always Go To First URL If Detection Is Not Possible. In general, if the plug-in content is integral to your page, select this option; visitors without the plug-in will often be prompted by the browser to download the plug-in. If the plug-in content is not essential to your page, leave this option deselected.

Note

This option applies only to Internet Explorer; Netscape Navigator can always detect plug-ins.

7. Click OK.

8. Select an event from the list menu.

9. Click the File menu, point to Preview In Browser, and then select a browser to test the page from the available options.

Important

Plug-in detection is not possible in Internet Explorer on the Macintosh, and most plug-ins cannot be detected in Internet Explorer on Windows.
