My97DatePicker日期筛选 限制开始日期不能晚于结束日期；最大间距1年

方式一：直接利用控件属性——

         <%--开始日期不能晚于结束日期；最大间距1年--%>
            &nbsp;&nbsp;创建时间：<input id="FCreatedTimeBegin" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(1,'FCreatedTimeEnd');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', maxDate: '#F{$dp.$D(\'FCreatedTimeEnd\')||\'%y-%M-%d\'}',minDate:date})" class="txt txtSearch" />
            至：<input id="FCreatedTimeEnd" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(2,'FCreatedTimeBegin');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', minDate: '#F{$dp.$D(\'FCreatedTimeBegin\')}',maxDate:date})" class="txt txtSearch" />
            &nbsp;&nbsp;完成时间：<input id="FCompletedTimeBegin" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(1,'FCompletedTimeEnd');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', maxDate: '#F{$dp.$D(\'FCompletedTimeEnd\')||\'%y-%M-%d\'}',minDate:date})" class="txt txtSearch" />
            至：<input id="FCompletedTimeEnd" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(2,'FCompletedTimeBegin');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', minDate: '#F{$dp.$D(\'FCompletedTimeBegin\')}', maxDate:date})" class="txt txtSearch" />

方式二：自定义函数——

  &nbsp;&nbsp;创建时间：<input id="FCreatedTimeBegin" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(1,'FCreatedTimeEnd');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', maxDate: '#F{$dp.$D(\'FCreatedTimeEnd\')}',minDate:date})" class="txt txtSearch" />
            至：<input id="FCreatedTimeEnd" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(2,'FCreatedTimeBegin');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', minDate: '#F{$dp.$D(\'FCreatedTimeBegin\')}',maxDate:date})" class="txt txtSearch" />
            &nbsp;&nbsp;完成时间：<input id="FCompletedTimeBegin" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(1,'FCompletedTimeEnd');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', maxDate: '#F{$dp.$D(\'FCompletedTimeEnd\')}',minDate:date})" class="txt txtSearch" />
            至：<input id="FCompletedTimeEnd" runat="server" type="text" readonly="readonly" onfocus="var date=limitMonthDate(2,'FCompletedTimeBegin');WdatePicker({dateFmt:'yyyy-MM-dd',vel:'d244_2', minDate: '#F{$dp.$D(\'FCompletedTimeBegin\')}', maxDate:date})" class="txt txtSearch" />

    var DateString;
    if (e == 2) {

        } else {
            return t;
        }
    }
