javascript - ExtJS 将多个 vType 应用于一个字段

Question

我见过为一个字段使用内置 vType 和自定义 vType 的示例，但从未见过同时使用自定义 vType 和内置 vType 的示例。例如，这是我目前在我的代码中使用的一个，它是我从 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;
        }

});

虽然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，而且我可能会很好地添加，但它会覆盖默认值，默认值会检查用户是否以正确的格式输入日期。有什么方法可以让高级 vType 和默认 vType 同时工作？现在用户只需在这些字段中输入字母或输入错误的日期格式，答案就会在没有错误检查的情况下提交!如果我已经存在多个 vType 的东西，我不想重写已经写过的东西并重新发明轮子。

谢谢你的时间，

编辑我根据要求添加了更多的表单代码。它很长，所以我剪掉了一些。我希望这就足够了......

this.captchaURL = "captcha/CaptchaSecurityImages.php?width=160&height=80&characters=4&t=";

var boxCaptcha =    new Ext.BoxComponent({
    columnWidth:.35,    
    autoEl: {
                tag:'img'
                ,id: 'activateCodeImg'
                ,src:this.captchaURL+new Date().getTime()
            }
});

boxCaptcha.on('render',function (){
var curr = Ext.get('activateCodeImg');
curr.on('click',this.onCapthaChange,this);
},this);

function onCapthaChange(){
    var captchaURL = this.captchaURL;
    var curr = Ext.get('activateCodeImg');
    curr.slideOut('b', {callback: function(){
                Ext.get( 'activateCodeImg' ).dom.src= captchaURL+new Date().getTime();
                curr.slideIn('t');      
    }},this);
}

function getLang(){
     // decode language passed in url
   var locale = window.location.search 
                ? Ext.urlDecode(window.location.search.substring(1))
                : '';

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。

关于用户键入简单文本而不是日期，我无法复制它!可能你应该显示你的表单代码和你的问题。看看这个:
