JavaScript is a scripting language that uses objects. For example, your browser window is an object. We can refer to this object via JavaScript by using "window."
The following is a method (action) of the window object. This method is envoked by using the following code:
window.prompt("Please enter your name.", "");
The prompt reply is saved to a variable by using the following code:
var name;
name = window.prompt("Please enter your name.", "")' ;
The first line creates a variable by the name of 'name.' The second line sets 'name' equal to the reply of the prompt.
Here's the code to generate the prompt:
<script language="JavaScript" type="text/javascript">
// Create the variable
var name;
// Ask the user to type in their name
// I left the prompt blank by leaving out the second string
name = window.prompt("Please enter your name.", "");
//Write the name to the document.
window.document.writeln("<strong>Welcome to my Web page, " + name + "!</strong>");
window.document.writeln(name + ", you are so beautiful to look at!");
window.document.writeln("Mr. Chagoyan, however, is still much more handsome!");
</script>
