I used two html inputs in this example. They are textbox and a button.
id for textbox is txt1 and it is used to get its value using javascript code.
value entered in texbox txt1 is saved in variable a and then it is displayed in alert box using function f1.
onclick event is fired when user click on a button to execute javascript code written inside function f1.
HTML and Javascript code to display text entered by user in alert box
<html>
<head>
<script type="text/javascript" >
function f1()
{
var a = document.getElementById("txt1").value;
alert(a);
}
</script>
</head>
<body>
<input type="text" id="txt1"/>
<br/>
<input type="button" value="Click" onclick="f1()"/>
</body>
</html>
