我正在建立一個Web應用程序,其中有一個日期的輸入框。我怎樣才能將數據綁定到我的後臺代碼? 我試着直接做,但我猜一個輸入框只能處理字符串,所以一個轉換爲字符串方法等。綁定日期到角度飛鏢inpubtbox
<div>
<label>start date: </label>
<input [(ngModel)]="item.stringStartDate" placeholder="start date" type="date">
</div>
void set startDate(DateTime startDate)
{
_startDate = startDate;
}
void set stringStartDate(String startDate)
{
this.startDate = parseDate(startDate);
}
static DateTime parseDate(String formattedString)
{
final RegExp r = new RegExp(
r'^(\d\d)-?(\d\d)-?([+-]?\d{4,6})');
Match match = r.firstMatch(formattedString);
if (match != null)
{
int years = int.parse(match[3]);
int month = int.parse(match[2]);
int day = int.parse(match[1]);
return new DateTime(years, month, day);
}
else
{
throw new FormatException("Invalid date format", formattedString);
}
}
static String dateToString(DateTime date){
if (date == null)
return null;
String ret = "${date.year}/";
if (date.month < 10)
ret+="0";
ret+="${date.month}/";
if (date.day < 10)
ret += "0";
ret+="${date.day}";
return ret;
}
的伎倆感謝 –
