I was recently asked how to cancel Tab Key on a TextBox and instead call a custom function using jQuery. Here’s the code for it:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Call Custom functions on Tab KeyPress in TextBoxes</title>
<script src="http://code.jquery.com/jquery-latest.js"
type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$('input.tabcancel').bind('keydown', function(e) {
var keyCode = e.keyCode e.which;
if (keyCode == 9) {
e.preventDefault();
alertMe();
}
});
});
function alertMe() {
var $par = $("#para");
$par.html('perform some action here');
setTimeout(function() {
$par.empty();
}, 1000);
}
</script>
</head>
<body>
<input type="text" class="tabcancel" /><br />
<input type="text" class="tabcancel" /><br />
<input type="text" /><br />
<input type="text" class="tabcancel" /><br />
<p id="para"/>
</body>
</html>
The code shown above handles the keydown event on all textboxes with the class ‘tabcancel’. The keyCode == 9 determines the tab key and we cancel the tab using e.preventDefault() and call a custom function alertMe(). The setTimeout() empties the contents of the para after 1 second.
