// specifying a submitHandler prevents the default submit, good for the demo

// set this class to error-labels to indicate valid fields
success: function(label) {
// set as text for IE
label.html(" ").addClass("checked");
}
});
// propose username by combining first- and lastname
$("#username").focus(function() {
var firstname = $("#firstname").val();
var lastname = $("#lastname").val();
if(firstname && lastname && !this.value) {
this.value = firstname + "." + lastname;
}
});
});
[/code]
两个问题：
1.后边的success: function(label)这里的label参数传进的是什么，是哪来的？
2.如果自定义正则表达式来匹配，怎么写？

[b]问题补充：[/b]
谢谢jones：按你的提示看了下源码，errorPlacement: function(error, element)这里的error参数传进来的就是一个label。
[b]还有第2个问题是是否可以用自定义的正则表达式？难道要改源码在源码里定义？[/b]
再附带个小疑问：）这里：
[code="java"]
// set as text for IE
label.html(" ").addClass("checked");
[/code]
这里为IE在label里放一个空格什么讲究呢？
