我见过使用内置 vType 和自定义 vType 作为字段的示例，但从来没有同时使用自定义和内置 vType。例如，这是我目前在我的代码中使用的一个，我从 Sencha 示例和论坛中找到的（非常感谢）：

//Add the additional 'advanced' VTypes
Ext.apply(Ext.form.VTypes, {
    daterange : function(val, field) {
        var date = field.parseDate(val);

        if(!date){
            return false;
        }
        if (field.startDateField) {
            var start = Ext.getCmp(field.startDateField);
            if (!start.maxValue || (date.getTime() != start.maxValue.getTime())) {
                start.setMaxValue(date);
                start.validate();
            }
        }
        else if (field.endDateField) {
            var end = Ext.getCmp(field.endDateField);
            if (!end.minValue || (date.getTime() != end.minValue.getTime())) {
                end.setMinValue(date);
                end.validate();
            }
        }
        /*
         * Always return true since we're only using this vtype to set the
         * min/max allowed values (these are tested for after the vtype test)
         */
            return true;
        }

});

尽管这可以防止用户选择按时间顺序不正确的开始和结束日期，并且我可以很好地添加，但它会覆盖默认值，该默认值会检查用户是否以正确的格式输入日期。有什么方法可以同时让高级 vType 和默认 vType 工作？现在用户只需在这些字段中输入字母或不正确的日期格式，就会提交答案而不会检查错误！如果已经存在让我拥有多个 vType 的东西，我不想重写已经编写的内容并重新发明轮子。

谢谢你的时间，

编辑 我正在按要求添加更多表单代码。很长，所以我剪掉了一部分。我希望这已经足够了……

如果您查看 Ext JS 源代码，您会看到 vType 是对字段的附加验证，并且会执行默认验证。因此，即使您将 'daterange' 作为新的 vType，也会执行现有的日期检查。

现在，关于用户键入正确的格式..您是在谈论日期格式 m/d/y 和 d/m/y 吗？format属性应该解决这个问题。您可以将 format: 'm/d/Y' 设置为您的两个日期字段。

关于用户键入简单文本而不是日期，我无法复制它！您是否应该显示您的表单代码以及您的问题。看看这个：在此处输入图像描述

我找了一个类似的问题。我找到了解决方案，也许它对您的问题也有帮助。

您可以为您的字段添加一个附加参数（例如 vTypes），将该字段声明为 Array。

你可以像这样在任何地方使用它：

field.vtypes.forEach(function(vType)
{
     vErrors[vType] = Ext.data.validations[vType]('', val);
});

您收到一个带有 Vtype 的数组和一个用于错误状态的布尔值；）
