You Can find screen Resolution in javascript using following code:
var screenW = 640, screenH = 480;
if (parseInt(navigator.appVersion) > 3) {
screenW = screen.width;
screenH = screen.height;
}
else if (navigator.appName == "Netscape"
&& parseInt(navigator.appVersion) == 3
&& navigator.javaEnabled()
) {
var jToolkit = java.awt.Toolkit.getDefaultToolkit();
var jScreenSize = jToolkit.getScreenSize();
screenW = jScreenSize.width;
screenH = jScreenSize.height;
}
if (parseInt(navigator.appVersion) > 3) {
screenW = screen.width;
screenH = screen.height;
}
else if (navigator.appName == "Netscape"
&& parseInt(navigator.appVersion) == 3
&& navigator.javaEnabled()
) {
var jToolkit = java.awt.Toolkit.getDefaultToolkit();
var jScreenSize = jToolkit.getScreenSize();
screenW = jScreenSize.width;
screenH = jScreenSize.height;
}
document.write("screenW " + screenW );
document.write("screenH " + screenH );
