To change text in status bar of a browser window, we just change "status" member of "window" object, which represents our entire browser window:

window.status = "This is some text";

----------------------------------------------- Using an input box to get text from user -----------------------------------------------

Just like in traditional windows applications, we can use an input box to get some text input from user. The "prompt" function is all we need:

var name = prompt("What is your name?"); document.write("Hello " + name);

The prompt function accepts just one argument (the title of input box), and returns value entered into text box. In example above, we get users name and store it in "name" variable. We then use "document.write" function to output their name into browser window.

----------------------------------------------- Using a message box to display text to user -----------------------------------------------

We can display a message box containing an OK button. These are great when you want to let user know what is happening during their time on a particular page. We can use a message box to display "name" variable from our previous example:

var name = prompt("What is your name?"); alert("Your name is: " + name);

The "alert" function takes one argument, which is text to display inside of message box.

----------------------------------------------- Changing title of browser window -----------------------------------------------

To change title of our web browser's window, we simply modify "document.title" variable, like this:

document.title = "My new title";

One bad thing about "document.title" variable is that we can only manipulate it in Microsoft Internet Explorer. Netscape's implementation of JavaScript doesn't allow us to modify it.

----------------------------------------------- In Closing -----------------------------------------------

As you can see from examples in this article, JavaScript is a powerful scripting language that we can use to enhance our visitors experience with our site. You shouldn't use JavaScript too much, however, because in some cases it can annoy your visitors and send them packing before your site even loads!

Where 'http://www.yourdomain.com/ADDRESS-TO/subscribe.js' is path to your subscribe.js file. You have uploaded it to your server right?

Include following code in BODY section of your html code:

Where 'subscribeaddress@yourdomain.com' is subscribe e-mail address of your list.

The above code will insert a form button in your page and so it is desirable that you insert above code preferably at bottom of your page.

Next, insert following attribute in BODY tag of your html page:

onLoad="popit()"

So your BODY tag will look something like this:

That's it !!!

Please don't install this code in all pages of your web site. It will surely be a turn off. Use it wisely.

The only disadvantage of this E-mail Capture box is that those with their e-mail clients not configured properly, won't be able to subscribe to your list :-( Also, your visitor's browser needs to Javascript enabled.

The MAIN ADVANTAGE of this E-mail Capture box is that you'll get genuine e-mail addresses and not fake addresses. The people who subscribe through these E-mail Capture boxes are bound to get your newsletter!

Try it!
