I have a problem with jQuery Validator. I want to use "required" property on a text input. It doesn't work when input has set value attribute by HTML code (tested on Firefox (3.5), and on IE 8 - on IE it works a bit better).
Story: 1. Page loads; 2. value is cleared; 3. focus is changed. 4. Nothing happens but the error message should be displayed; 5. getting back to the field and typing some characters. 6. changing focus; 7. getting back to the field; 8. clearing the field. 9. Error is displayed even before leaving the field.
The HTML code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<script src="Web/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script>
<script src="Web/Scripts/jquery.validate.js" type="text/javascript"></script>
</head>
<body>
<form id="form1">
<input type="text" id="name1" name="name1" value="test" /><br />
<input type="text" />
</form>
<script type="text/javascript">
$(document).ready(function() {
var validator = $("form").validate({
rules: {
name1: {
required: true,
minlength: 2
}
},
messages: {
name1: "bad name"
},
});
});
</script>
</body>
</html>

You can override the onfocusout handler to make this work like you want (more eager):
$(function() {
var validator = $("form").validate({
rules: { name1: { required: true, minlength: 2 } },
messages: { name1: "bad name" },
onfocusout: function(element) { $(element).valid(); }
});
});
You can see the old broken demo (like your question) here and the updated one with onfocusout that works here.
