Question

I wasted 4 hours searching and trying, but no luck.

if ((navigator.plugins) && (navigator.plugins.length)) {
    for (var xx = 0, l = navigator.plugins.length; xx < l; xx++) {    
        var tn = navigator.plugins[xx].name;    
        if (tn.indexOf("Java") != -1) {
            document.write("Found ");
        } 
        else {
            document.write("Nothing ");
        }    
    }
}

Insteading of writing just “Found” or “Nothing” this script writes the following:

NothingNothingFoundNothing

(there are 4 plugins btw):

How do I fix this so that I only receive one answer? I don’t want other way to find if Java is installed, just the above but working.

Edit:
Thanks both of you, now it’s working.

Answer 1

if ((navigator.plugins) && (navigator.plugins.length)) { 
    var found = false;
    for (var xx = 0, l = navigator.plugins.length; xx < l; xx++) { 

        var tn = navigator.plugins[xx].name; 

        if (tn.indexOf("Java(TM)") { 
           found = true;
        } 

    } 
    if(found) { 
        document.write("Java "); 
    } else { 
        document.write("Nothing "); 
    }
}
