Question

error when calling applet method with javascript

Answer 1

A:

Perhaps you are missing the CLASSID attribute of the object tag? Also try changing the function to use document.getElementById

function getMAC(){
   // ...
   a=document.getElementById("jsap").readMACaddress();
   // ...
}

More about the classId attribute is documented here

i changed the script as you said.still the problem is existing .. the error was "Object doesn't support this property or method"

Have you tried adding the classid attribute to the object tag?

Answer 2

A:

According to http://download.oracle.com/docs/cd/E17409_01/javase/6/docs/technotes/guides/plugin/developer_guide/java_js.html, syntax changes from object, applet and embed tags. The 'MAYSCRIPT' attribute should be uppercase (maybe case matters).

I'd try using 'true' instead of 'yes' as suggested by the same page above.

I seem to recall that you need to use MAYSCRIPT as an attribute instead of a parameter, with IE. So I'd try something like

<object type="application/x-java-applet"
  classid="clsid:CAFEEFAC-0016-0000-0000-ABCDEFFEDCBA" 
 width= "180" height= "180"  name="jsap" id="jsap" MAYSCRIPT="true" >
  <param name="archive" value="macaddr.jar" />
  <param name="code" value="com/mac/GeneralApplet"  />
  <param name="MAYSCRIPT" value="true" />
  <param name="scriptable" value="true" />
</object>

Also, you mention (if I understood correctly) that the problem happens at load time. Try calling your method from the onLoad event of the body element, which should ensure that every resource has been loaded before being triggered.

<body onLoad="yourCode();" />

Hope it helps.
