Answer 1

My97我知道的，但是我使用的是Extjs的日期控件

Answer 2

楼上的都是浮云，
Ext的例子包里面就已经包含了两个日期控件的验证，
楼主也是大意，Ext4.x的例子请参考
http://dev.sencha.com/deploy/ext-4.0.2/examples/form/adv-vtypes.html
Ext3.x的类似。你下载一个源码，在例子包里面的examples/form/adv-vtypes.html文件。
Ext都封装好了，不用自己在做什么判断。

Answer 3

我是使用的Ext3.0，就是参考例子做的，注意问题是需要结束日期大于开始日期，而不是大于等于，我在验证方法中做过尝试，可惜是个新手，希望得到高手的指点

Answer 4

问题解决了，下面把代码贴出来，仅供参考，有不对的地方欢迎指出：
{
                xtype:'datefield',
                name:"startDt",
                id:'startDt',
                fieldLabel:TXT.PROJECT_FORM_FIELD_STARTDATE,
                format:"Y-m-d",
                anchor:"65%",
                editable:false,
                listeners: {
                    'select': function(f) {
                        var newDate = new Date(new Date(f.getValue()).valueOf() + 1 * 24 * 60 * 60 * 1000);
                        Ext.getCmp("endDt").setMinValue(newDate);
                    }
                }
            },
            {
                xtype:'datefield',
                name:"endDt",
                id:'endDt',
                fieldLabel:TXT.PROJECT_FORM_FIELD_ENDDATE,
                format:"Y-m-d",
                anchor:"65%",
                editable:false,
                listeners: {
                    'select': function(f) {
                        var newDate = new Date(new Date(f.getValue()).valueOf() - 1 * 24 * 60 * 60 * 1000);
                        Ext.getCmp("startDt").setMaxValue(newDate);
                    }
                }
            },按钮“reset”的时候记得：
                                Ext.getCmp("startDt").setMaxValue();
                                Ext.getCmp("endDt").setMinValue();
                                panel.form.reset();发分了……
