Question

jQuery日历放在第二个调用“false”表示！即在第一个“Von”（从）字段中单击用户，正确调用日历。如果用户单击“Bis”（to）字段，则会正确调用日历。但是用户点击抵制日历上的“Von”（来自）字段被错误地调用，用户可以无限制地调用日历的“未来”滚动！

这里集成了源代码：

<script>
            $(function() {
                $(function() {
                    $( "#date_Von" ).datepicker({
                        dateFormat: 'dd.mm.yy',
                        changeMonth: true,
                        changeYear: true,
                        numberOfMonths: 3,
                        dayNamesMin: [ "So","Mo", "Di", "Mi", "Do", "Fr", "Sa" ],
                        monthNamesShort: [ "Jan", "Feb", "Mär", "Apr", "Mai", "Jun", "Jul", "Aug", "Sep", "Okt", "Nov", "Dez" ],
                        monthNames: ["Januar","Februar","März","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember"],
                        maxDate: "+0d",
                        minDate: new Date(2007, 1 - 1, 1),
                        prevText: "Zurück",
                        nextText: "Weiter",
                        onClose: function( selectedDate ) {
                            $( "#date_Bis" ).datepicker( "option", "minDate", selectedDate ); 
                        }
                    });
                    $( "#date_Bis" ).datepicker({
                        dateFormat: 'dd.mm.yy',
                        changeMonth: true,
                        changeYear: true,
                        numberOfMonths: 3,
                        dayNamesMin: [ "So","Mo", "Di", "Mi", "Do", "Fr", "Sa" ],
                        monthNamesShort: [ "Jan", "Feb", "Mär", "Apr", "Mai", "Jun", "Jul", "Aug", "Sep", "Okt", "Nov", "Dez" ],
                        monthNames: ["Januar","Februar","März","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember"],
                        maxDate: "+0d",
                        minDate: new Date(2007, 1 - 1, 1), 
                        prevText: "Zurück",
                        nextText: "Weiter",
                        onClose: function( selectedDate ) {
                            $( "#date_Von" ).datepicker( "option", "maxDate", selectedDate );
                        }
                    });
                });
            });
   </script>

首先致电：

在“Von”（From）字段中第二次单击后：

有谁知道为什么会这样？

Answer 1

问题是当你关闭第二个日期选择器而没有选择日期时，maxDate被设置为空白，有效地从第一个字段中删除了验证。

因此，一种可能的解决方案是使用onSelect事件

b.jsp

如果要使用关闭处理程序本身，则如果日期为空，则设置默认约束值

    <%!
   Connection connection = null;
    Statement statement = null;
%>
<%
    try {
    Class.forName("org.postgresql.Driver");
        connection =   DriverManager.getConnection("jdbc:postgresql://localhost:5432/test", "postgres", "root");
    statement = connection.createStatement();

    } catch (Exception e) {
    out.println(e.getMessage());
    }
%>
<%!
  public List select(String query) {
    List rows = new ArrayList();
    Map row = null;


    try {
        ResultSet resultSet = statement.executeQuery(query);
        ResultSetMetaData metaData = resultSet.getMetaData();
        int numColumns = metaData.getColumnCount();

        while (resultSet.next()) {
            row = new HashMap();
            for (int i = 1; i < numColumns + 1; i++) {
                row.put(metaData.getColumnName(i), resultSet.getObject(i));
            }
            rows.add(row);
        }

        resultSet.close();
    } catch (Exception e) {

    }

    return rows;
}
%>

datepicker，第二次调用后没有正确显示
