Please help me with this plug-in detector + video loader window.

rbaibich · 07-10-2005, 11:56 PM

I'm making a website for a news show, and I'm using MovableType as the CMS for this. I have a bar with the latest shows so people can click on it and watch the whole thing.

I put a string in the MT template so the popup window address is something like yadayada.html?2005-07-10. I have a script that does the browser check for what video plugins are installed, but I'm having a hard time writing the part where it automatically chooses which code to use and calls the right video using the URL substring. Here's where I'm at right now:

Code:

<script language="JavaScript">
<!--

// initialize global variables
var detectableWithVB = false;
var pluginFound = false;


function goURL(daURL) {
    // if the browser can do it, use replace to preserve back button
    if(javascriptVersion1_1) {
	window.location.replace(daURL);
    } else {
	window.location = daURL;
    }
    return;
}

function redirectCheck(pluginFound, redirectURL, redirectIfFound) {
    // check for redirection
    if( redirectURL && ((pluginFound && redirectIfFound) ||
	(!pluginFound && !redirectIfFound)) ) {
	// go away
	goURL(redirectURL);
	return pluginFound;
    } else {
	// stay here and return result of plugin detection
	return pluginFound;
    }
}

function canDetectPlugins() {
    if( detectableWithVB || (navigator.plugins && navigator.plugins.length > 0) ) {
	return true;
    } else {
	return false;
    }
}

function detectFlash(redirectURL, redirectIfFound) {
    pluginFound = detectPlugin('Shockwave','Flash');
    // if not found, try to detect with VisualBasic
    if(!pluginFound && detectableWithVB) {
	pluginFound = detectActiveXControl('ShockwaveFlash.ShockwaveFlash.1');
    }
    // check for redirection
    return redirectCheck(pluginFound, redirectURL, redirectIfFound);
}

function detectDirector(redirectURL, redirectIfFound) {
    pluginFound = detectPlugin('Shockwave','Director');
    // if not found, try to detect with VisualBasic
    if(!pluginFound && detectableWithVB) {
	pluginFound = detectActiveXControl('SWCtl.SWCtl.1');
    }
    // check for redirection
    return redirectCheck(pluginFound, redirectURL, redirectIfFound);
}

function detectQuickTime(redirectURL, redirectIfFound) {
    pluginFound = detectPlugin('QuickTime');
    // if not found, try to detect with VisualBasic
    if(!pluginFound && detectableWithVB) {
	pluginFound = detectQuickTimeActiveXControl();
    }
    return redirectCheck(pluginFound, redirectURL, redirectIfFound);
}

function detectReal(redirectURL, redirectIfFound) {
    pluginFound = detectPlugin('RealPlayer');
    // if not found, try to detect with VisualBasic
    if(!pluginFound && detectableWithVB) {
	pluginFound = (detectActiveXControl('rmocx.RealPlayer G2 Control') ||
		       detectActiveXControl('RealPlayer.RealPlayer(tm) ActiveX Control (32-bit)') ||
		       detectActiveXControl('RealVideo.RealVideo(tm) ActiveX Control (32-bit)'));
    }
    return redirectCheck(pluginFound, redirectURL, redirectIfFound);
}

function detectWindowsMedia(redirectURL, redirectIfFound) {
    pluginFound = detectPlugin('Windows Media Player');
    // if not found, try to detect with VisualBasic
    if(!pluginFound && detectableWithVB) {
	pluginFound = detectActiveXControl('MediaPlayer.MediaPlayer.1');
    }
    return redirectCheck(pluginFound, redirectURL, redirectIfFound);
}

function detectPlugin() {
    // allow for multiple checks in a single pass
    var daPlugins = detectPlugin.arguments;
    // consider pluginFound to be false until proven true
    var pluginFound = false;
    // if plugins array is there and not fake
    if (navigator.plugins && navigator.plugins.length > 0) {
	var pluginsArrayLength = navigator.plugins.length;
	// for each plugin...
	for (pluginsArrayCounter=0; pluginsArrayCounter < pluginsArrayLength; pluginsArrayCounter++ ) {
	    // loop through all desired names and check each against the current plugin name
	    var numFound = 0;
	    for(namesCounter=0; namesCounter < daPlugins.length; namesCounter++) {
		// if desired plugin name is found in either plugin name or description
		if( (navigator.plugins[pluginsArrayCounter].name.indexOf(daPlugins[namesCounter]) >= 0) ||
		    (navigator.plugins[pluginsArrayCounter].description.indexOf(daPlugins[namesCounter]) >= 0) ) {
		    // this name was found
		    numFound++;
		}
	    }
	    // now that we have checked all the required names against this one plugin,
	    // if the number we found matches the total number provided then we were successful
	    if(numFound == daPlugins.length) {
		pluginFound = true;
		// if we've found the plugin, we can stop looking through at the rest of the plugins
		break;
	    }
	}
    }
    return pluginFound;
} // detectPlugin

Is this the way to go? This is not working, but I don't even know where to start. Would there be an easier way to do it?
