The principle is this JS:

1Window.onload =function() {2     varv8string = ' function%20javaenabled%28%29%20%7b%20%5bnative%20code%5d%20%7d ';3 4     if(Window.devicepixelratio)//If WebKit Browser5     {6         if(Escape (navigator.javaEnabled.toString ()) = = =v8string) {7Display (' V8 detected ');8}Else {9Display (' JSC detected ');Ten         } One}Else { ADisplay ("Not a WebKit browser"); -     } -  the     functionDisplay (msg) { -         varp = document.createelement (' P '); -p.innerhtml =msg; - Document.body.appendChild (p); +     } -  +};
