Name

MAYSCRIPT — NN 3 IE 4 HTML n/a

Synopsis

MAYSCRIPT

Optional

Navigator 3 introduced a technology called LiveConnect, which allowed scripts to communicate with Java applets and vice versa. For security reasons, an applet’s communications facilities with scripts must be explicitly switched on by the page author. By adding the MAYSCRIPT attribute to the applet’s tag, an applet that is written to take advantage of the document objects and scripts can address those items. In other words, the HTML is granting the applet the ability to reach scripts in the document. This attribute is a simple switch: when the attribute name is present, it is turned on.

One more step is required for an applet to communicate with JavaScript. The applet code must import a special Netscape class called JSObject.class. This class file (and its companion exception class) are built into the Java support in the Windows version of Internet Explorer 4. Although the execution is not perfect in IE 4, applets can perform basic communication with scripts.

Example

<APPLET CODE="ScriptableClock.class" WIDTH=400 HEIGHT=50 MAYSCRIPT>
</APPLET>

Value

No value assigned to the attribute. The presence of the attribute name sets turns on applet-to-script communication.

Default

Off.
