/* OTF_NOTF_winLoaded.js v0.3.7 by Eric Gerds - This script, together with PluginDetect and getJavaInfo.jar, is capable of doing both OTF and NOTF Java detection. - NOTF detection can only be performed by this script if the PluginDetect script is generated with the "NOTF" checkbox enabled. - Java Detection is performed AFTER the browser window has loaded. - Feel free to change this script, remove comments, etc... to fit your own needs. USAGE: 1) Insert the PluginDetect script in the of your HTML page: 2) Insert the output
in the of your HTML page. This div will receive the plugin detection results:
3) If you wish to use the plugindetect
, then place it wherever you wish in the . For example:
4) Insert the OTF_NOTF_winLoaded.js script anywhere after the PluginDetect script It does not matter too much where you place this script because it waits until the window has loaded before doing any detection. 5) Get a copy of the "getJavaInfo.jar" jarfile and put it in the same folder as your HTML page. If you put the jarfile in a different directory than the HTML page, then you must adjust the path of the jarfile. The jarfile path is always relative to the web page. For example, say your web page is at http://www.mysite.com/webpage.htm and you have the jarfile at http://www.mysite.com/stuff/getJavaInfo.jar then jarfile = "stuff/getJavaInfo.jar" If your web page is at http://www.mysite.com/webpage.htm and you have the jarfile at http://www.mysite.com/getJavaInfo.jar then jarfile = "getJavaInfo.jar" */ // GLOBAL VARIABLES var g_debugCheckJava = false; // Allows to activate debug. var g_checkJava = false; // Indicates if detection is done. var PD = PluginDetect; var outputNode = 'javaresult'; // Id of output
