本地化org.apache.wicket.extensions.yui.calendar.DatePicker中的標籤

Question

有誰知道如何本地化org.apache.wicket的「Month」，「Year」，「Okay」和「Cancel」標籤。 extensions.yui.calendar.DatePicker？

根據API，您可以重寫localize（Map）方法來設置本地化的字符串，但是我找不到相應屬性的名稱。

Answer 1

該ticket 754添加支持localization。

可能是patch introduced then可以給你一些線索嗎？它引用：

src/main/java/org/apache/wicket/extensions/yui/calendar/locale/DatePicker_de.properties 

有：

DATE_FIELD_DELIMITER=x 
MDY_DAY_POSITION=1 
MDY_MONTH_POSITION=2 
MDY_YEAR_POSITION=3 
MD_DAY_POSITION=1 
MD_MONTH_POSITION=2 

MONTHS_SHORT=Jan,Feb,M\u00E4r,Apr,Mai,Jun,Jul,Aug,Sep,Okt,Nov,Dez 

MONTHS_LONG=Januar,Februar,M\u00E4rz,April,Mai,Juni,Juli,August,September,Oktober,November,Dezember 
WEEKDAYS_1CHAR=S,M,D,M,D,F,S 
WEEKDAYS_SHORT=So,Mo,Di,Mi,Do,Fr,Sa 
WEEKDAYS_MEDIUM=Son,Mon,Die,Mit,Don,Fre,Sam 
WEEKDAYS_LONG=Sonntag,Montag,Dienstag,Mittwoch,Donnerstag,Freitag,Samstag

關於標籤本身的定位，可能是你可以嘗試：

• getResourceSettings()在"Everything about Wicket internationalization"
提到
• 比this thread了類似的方法（這是另一個組件）
• 檢查dateTimePicker的代碼this page
• 退房的project Wicket-Calendar，看看有沒有JSCalendar賴以DatePicker seems to be based代碼線索本身
• 退房。

我想你是在談論日曆導航器上的標籤。這example可能會有所幫助。

根據this您可以通過覆蓋的DatePicker類的配置方法本地化標籤：

public class DatePicker extends org.apache.wicket.extensions.yui.calendar.DatePicker { 

    @Override 
    protected void configure(Map<String, Object> widgetProperties) { 
     super.configure(widgetProperties); 

     /* 
     * var navConfig = { 
     * strings: { 
     * month:"Calendar Month", 
     * year:"Calendar Year", 
     * submit: "Submit", 
     * cancel: "Cancel", 
     * invalidYear: "Please enter a valid year" 
     * }, 
     * monthFormat: YAHOO.widget.Calendar.SHORT, 
     * initialFocus: "month" 
     * } 
     */ 

     Map<String, Object> strings = new HashMap<String, Object>(); 
     strings.put("month", "Месяц"); 
     strings.put("year", "Год"); 
     strings.put("submit", "Ok"); // put label for 'Okay' button 
     strings.put("cancel", "Отмена"); // put label for 'Cancel' button 
     strings.put("invalidYear", "Введите корректный год"); 

     Map<String, Object> props = new HashMap<String, Object>(); 
     props.put("strings", strings); // pass localization related parameters 
     props.put("monthFormat", "YAHOO.widget.Calendar.SHORT"); 
     props.put("initialFocus", "year"); 

     widgetProperties.put("navigator", props); 
    } 
} 

希望你會發現這個代碼片斷非常有用。

我認爲這個解決方案是好的：

protected static final String[] NAVIGATOR_LOCALIZATION_KEYS = { 
    "month", "year", "submit", "cancel", "invalidYear", 
}; 

In overridden method u should write: 

super.configure(widgetProperties, response, initVariables); 
    Map<String, String> strings = MapBuilder.newHashMap(); 
    for (String key : NAVIGATOR_LOCALIZATION_KEYS) { 
     strings.put(key, LocalizationUtils.getString(key)); 
    } 
    widgetProperties.put(
     "navigator", Collections.singletonMap("strings", strings) 
    );
