好的，我知道每个人的第一个想法是简单地创建另一个验证方法和消息。但这是交易。我们有一个表单，其中包含一个用作雇主姓名和公司名称的字段，具体取决于下拉列表中选择的内容。
我需要做的是当下拉列表显示他们拥有公司并且他们没有填写该字段然后它显示一条消息。如果他们不拥有公司并且它是空的，那么它会显示另一条消息。
我将如何做到这一点？这是使用最新版本的jQuery和Validate插件（http://jqueryvalidation.org/）。

答案 0 :(得分：12)
这是一种更清洁（也可能是正确的）方式
messages: {
RoutingNumber: {
required:"Message1",
digits: "Message2",
rangelength: "Message 3"
}
}

答案 1 :(得分：2)
使用the .rules('add') method动态更改select更改时的消息。然后使用the .valid() method在字段上触发新测试，以便立即更新消息。
$(document).ready(function () {
$('#myform').validate({
rules: {
type: {
required: true
},
theName: {
required: true
}
}
});
$('select[name="type"]').on('change', function () {
var theMessage,
theType = $(this).val();
if (theType == 'employer') {
theMessage = "Required Message 1";
} else if (theType == 'company') {
theMessage = "Required Message 2";
} else {
theMessage = "This field is required.";
}
// dynamically change the message
$('input[name="theName"]').rules('add', {
messages: {
required: theMessage
}
});
// trigger immediate validation to update message
$('input[name="theName"]').valid();
});
});
