 In this example, when a user types a character in the input field, a function called "showHint()" is executed.
 The function is triggered by the onkeyup event.
 eg-----

 <html>
 <head>
 <script>
 function showHint(str) {
    if (str.length == 0) { 
        document.getElementById("txtHint").innerHTML = "";
        return;
    } else {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("txtHint").innerHTML = this.responseText;
            }
        };
        xmlhttp.open("GET", "gethint.php?q=" + str, true);
        xmlhttp.send();
    }
 }
 </script>
 </head>
 <body>

 <p><b>Start typing a name in the input field below:</b></p>
 <form> 
 First name: <input type="text" onkeyup="showHint(this.value)">
 </form>
 <p>Suggestions: <span id="txtHint"></span></p>
