如何使用Java从selenium中的日历中自动选择特定日期

1）假设您可以在输入字段中输入日期，而日历仅是图标。你可以有这样的帮助方法

    public String threeDaysBefore(){    String threeDaysBefore = "";    Date date = new Date();    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.add(Calendar.DAY_OF_YEAR, -3);    Date before = cal.getTime();    SimpleDateFormat formatter = new SimpleDateFormat("dd.MM.yyyy HH:mm");    threeDaysBefore = formatter.format(before);    return threeDaysBefore;}

然后在代码中

  WebElement calendarManualInput = driver.findElement...// find the manual input field  calendarManualInput.sendKeys(threeDaysBefore());

2）如果您只能单击日历，那将更加棘手。您仍然需要String，但有一点不同：

    public String threeDaysBefore(){    String threeDaysBefore = "";    Date date = new Date();    Calendar cal = Calendar.getInstance();    cal.setTime(date);    cal.add(Calendar.DAY_OF_YEAR, -3);    Date before = cal.getTime();    SimpleDateFormat formatter = new SimpleDateFormat("dd");    threeDaysBefore = formatter.format(before);    return threeDaysBefore;}

但是，上面没有什么收获。如果日期是1.4。那么它将返回“ 29”，可以解释为29.4。你不想发生。因此，在代码后面，您可能必须这样做

//this will click three days beforeDate today = new Date();Date minusThree = new Date();Calendar now = Calendar.getInstance();now.setTime(today);Calendar before = Calendar.getInstance();before.setTime(minusThree);before.add(Calendar.DAY_OF_YEAR, -3);int monthNow = now.get(Calendar.MONTH);int monthBefore = before.get(Calendar.MONTH);if (monthBefore < monthNow){  // click previous month in the calendar tooltip on page}WebElement dateToSelect = driver.findElement(By.xpath("//span[text()='"+threeDaysBefore()+"']"));dateToSelect.click();
