yii 前端js动态添加验证规则

在使用 activeForm 生成表单及验证时，默认是按照 model 里的 rules 生成js验证，model 验证在加载完页面后生效，不可修改，如果需要扩展、动态验证，需要使用js来配合

直接上Dome吧：

$('#returnmanualform-refundway input[type="radio"]').on('click', function(){
    if($(this).is(':checked') && $(this).val()==3){
        $('.account-info').removeClass('hidden');

        // 添加验证规则
        $('#w0').yiiActiveForm('add', {
            "id": "returnmanualform-bankname",
            "name": "bankName",
            "container": ".field-returnmanualform-bankname",
            "input": "#returnmanualform-bankname",
            "validate": function(attribute, value, messages, deferred, form) {
                yii.validation.required(value, messages, { "message": "转账银行不能为空。" });
            }
        });

        $('#w0').yiiActiveForm('add', {
            "id": "returnmanualform-bankaccount",
            "name": "bankAccount",
            "container": ".field-returnmanualform-bankaccount",
            "input": "#returnmanualform-bankaccount",
            "validate": function(attribute, value, messages, deferred, form) {
                yii.validation.required(value, messages, { "message": "转账账号不能为空。" });
            }
        });

        $('#w0').yiiActiveForm('add', {
            "id": "returnmanualform-bankusername",
            "name": "bankUserName",
            "container": ".field-returnmanualform-bankusername",
            "input": "#returnmanualform-bankusername",
            "validate": function(attribute, value, messages, deferred, form) {
                yii.validation.required(value, messages, { "message": "用户名不能为空。" });
            }
        });
    }else{
        $('.account-info').addClass('hidden');

        // 移除验证规则
        $('#w0').yiiActiveForm('remove', "returnmanualform-bankname");
        $('#w0').yiiActiveForm('remove', "returnmanualform-bankaccount");
        $('#w0').yiiActiveForm('remove', "returnmanualform-bankusername");
    }
});
