Download Source Code : 592_BrowserProperties.zip

This article is about how you can display the browser properties to your user which includes code name, color depth, platform, if java is enabled, resolution, ip address and hostname.

 

Steps you will do.

 

 

Start visual studio and create a new web application.

 

Open the HTML design of your web page and add the following JavaScript functions before closing the head tag.

 

<script language="JavaScript">

 

function display() {

window.onerror=null;

 

colors = window.screen.colorDepth;

document.form.color.value = Math.pow (2, colors);

if (window.screen.fontSmoothingEnabled == true)

document.form.fonts.value = "Yes";

else document.form.fonts.value = "No";

 

document.form.navigator.value = navigator.appName;

document.form.version.value = navigator.appVersion;

document.form.colordepth.value = window.screen.colorDepth;

document.form.width.value = window.screen.width;

document.form.height.value = window.screen.height;

document.form.maxwidth.value = window.screen.availWidth;

document.form.maxheight.value = window.screen.availHeight;

document.form.codename.value = navigator.appCodeName;

document.form.platform.value = navigator.platform;

if (navigator.javaEnabled() < 1) document.form.java.value="No";

if (navigator.javaEnabled() == 1) document.form.java.value="Yes";

 

if(navigator.javaEnabled() && (navigator.appName != "Microsoft Internet Explorer")) {

vartool=java.awt.Toolkit.getDefaultToolkit();

addr=java.net.InetAddress.getLocalHost();

host=addr.getHostName();

ip=addr.getHostAddress();

alert("Your host name is '" + host + "'\nYour IP address is " + ip);

   }

}

</script>

 

  

Add the following HTML code to design the layout of your web form.

 

 

< body OnLoad="display()">

<center>

<form name="form">

<table border="1" width="468" style="WIDTH: 468px; HEIGHT: 334px">

<tr>

<td>current resolution:</td>

</tr>

<tr>

</tr>

<tr>
