Check Plugin

Page 449 highlights

Check Plugin Use the Check Plugin action to send visitors to different pages depending on whether they have the specified plugin installed. For example, you might want visitors to go to one page if they have Shockwave and another page if they do not. Note: You cannot detect specific plugins in Internet Explorer using JavaScript. However, selecting Flash or Director will add the appropriate VBScript code to your page to detect those plugins in IE on Windows. Plugin detection is impossible in IE on the Macintosh. To use the Check Plugin action: 1 Select an object and open the Behaviors panel. 2 Click the Plus (+) button and choose Check Plugin from the Actions pop-up menu. 3 Choose a plugin from the Plugin pop-up menu, or click Enter and type the exact name of the plugin in the adjacent field. You must use the exact name of the plugin as specified in bold on the About Plugins page in Navigator. (In Windows, choose Navigator's Help > About Plug-ins command; on the Macintosh, choose About Plug-ins from the Apple menu.) 4 In the If Found, Go To URL field, specify a URL for visitors who have the plugin. If you specify a remote URL, you must include the http:// prefix in the address. To make visitors with the plugin stay on the same page, leave this field blank. 5 In the Otherwise, Go To URL field, specify an alternative URL for visitors who don't have the plugin. To make visitors without the plugin stay on the same page, leave this field blank. 6 Plugin detection is not possible in Internet Explorer on the Macintosh, and most plugins cannot be detected in Internet Explorer on Windows. By default, when detection is impossible, the visitor is sent to the URL listed in the Otherwise field. To instead send the visitor to the first (If Found) URL, select the Always go to first URL if detection is not possible option. When selected, this option effectively means "assume that the visitor has the plugin, unless the browser explicitly indicates that the plugin is not present." In general, if the plugin content is integral to your page, select the "Always go to first URL if detection is not possible" option; visitors without the plugin will often be prompted by the browser to download the plugin. If the plugin content is not essential to your page, leave this option unselected. This option applies only to Internet Explorer; Navigator can always detect plugins. 7 Click OK. 8 Check that the default event is the one you want. If it isn't, choose another event from the pop-up menu. If the events you want are not listed, change the target browser in the Show Events For pop-up menu. Using Behaviors 449

Use the Check Plugin action to send visitors to different pages depending on
whether they have the specified plugin installed. For example, you might want
visitors to go to one page if they have Shockwave and another page if they do not.
Note:
You cannot detect specific plugins in Internet Explorer using JavaScript. However,
selecting Flash or Director will add the appropriate VBScript code to your page to detect
those plugins in IE on Windows. Plugin detection is impossible in IE on the Macintosh.
To use the Check Plugin action:
1
Select an object and open the Behaviors panel.
2
Click the Plus (+) button and choose Check Plugin from the Actions
pop-up menu.
3
Choose a plugin from the Plugin pop-up menu, or click Enter and type the
exact name of the plugin in the adjacent field.
You must use the exact name of the plugin as specified in bold on the About Plug-
ins page in Navigator. (In Windows, choose Navigator’s Help > About Plug-ins
command; on the Macintosh, choose About Plug-ins from the Apple menu.)
4
In the If Found, Go To URL field, specify a URL for visitors who have the plugin.
If you specify a remote URL, you must include the http:// prefix in the address.
To make visitors with the plugin stay on the same page, leave this field blank.
5
In the Otherwise, Go To URL field, specify an alternative URL for visitors who
don’t have the plugin.
To make visitors without the plugin stay on the same page, leave this field blank.
