the onkeyup method is supposedly not defined, however, the method is auto-recommended to me by my ide. When I view the error in chrome dev tools I get the error Uncaught TypeError: Object [object Object] has no method 'onkeyup'. I am using the latest version of jQuery. Here is my code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
var str = document.getElementById('txt1').value;
$.post("addName.php", {q: str});
});
$("input").onkeyup(function(){
var str = document.getElementById('txt1').value;
$.post("gethint.php", {q: str});
});
});
</script>
</head>
<body>
<h3>Start typing a name in the input field below:</h3>
<form action="">
First name: <input type="text" id="txt1"/>
</form>
<p>Suggestions: <span id="txtHint"></span></p>
<button> Add Name</button>
</body>
</html>

Definition and UsageThe onkeyup attribute fires when the user releases a key (on the keyboard). Tip: The order of events related to the onkeyup event: onkeydown. onkeypress.
Definition and Usagekeydown - The key is on its way down. keypress - The key is pressed down. keyup - The key is released.
The keyup event is fired when a key is released. The keydown and keyup events provide a code indicating which key is pressed, while keypress indicates which character was entered. For example, a lowercase "a" will be reported as 65 by keydown and keyup , but as 97 by keypress .
$("input").on('keyup', function(){
var str = document.getElementById('txt1').value;
$.post("gethint.php", {q: str});
});
or
$("input").keyup( function(){
var str = document.getElementById('txt1').value;
$.post("gethint.php", {q: str});
});
