jquery 关于模糊验证

Question

我正在使用 jquery 验证插件。点击“提交”按钮后，我的表单得到验证。但我需要 onblur 验证，例如：如果 html 文本框/其他元素失去焦点（onblur），那么我需要验证相应的字段。那么如何修改下面的代码呢？

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/
libs/jquery/1.3.0/jquery.min.js"></script>
<script type="text/javascript" src="jquery.validate.js"></script>
<script type="text/javascript" >
$(document).ready(function() {
$.validator.addMethod("email", function(value, element)
{
return this.optional(element) || /^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$/i.test(value);
}, "Please enter a valid email address.");

$.validator.addMethod("username",function(value,element)
{
return this.optional(element) || /^[a-zA-Z0-9._-]{3,16}$/i.test(value);
},"Username are 3-15 characters");

$.validator.addMethod("password",function(value,element)
{
return this.optional(element) || /^[A-Za-z0-9!@#$%^&*()_]{6,16}$/i.test(value);
},"Passwords are 6-16 characters");

// Validate signup form
$("#signup").validate({
rules: {
email: "required email",
username: "required username",
password: "required password",
},
});
});
</script>

提前致谢

根据docs，您可以在输入失去焦点时启用验证onfocusout：

$(".selector").validate({
    onfocusout: false
})

在你的情况下，具体来说：

$("#signup").validate({
    onfocusout: false,    //this setting is what you need
    rules: {
        email: "required email",
        username: "required username",
        password: "required password"
    }
});
