html - 任何人都有一些用于 asp.net mvc 的下拉列表日期选择器

Question

有人知道我在哪里可以找到 html 帮助程序或将生成由 3 个下拉菜单组成的日期选择器的东西吗？

Answer 1

这是我的小 helper 。

我相信这本身就是解释性的。可以调整以安排下拉菜单的顺序(月/日/年或日/月/年)，如果您使用的是 .NET 4，则可以为名称设置默认参数。

    TagBuilder daysList = new TagBuilder("select");
    TagBuilder monthsList = new TagBuilder("select");
    TagBuilder yearsList = new TagBuilder("select");

    daysList.Attributes.Add("name", dayName);
    monthsList.Attributes.Add("name", monthName);

    StringBuilder days = new StringBuilder();
    StringBuilder months = new StringBuilder();
    StringBuilder years = new StringBuilder();

    int beginYear = DateTime.UtcNow.Year - 100;
    int endYear = DateTime.UtcNow.Year;

    for (int i = 1; i <= 31; i++)
        days.AppendFormat("<option value='{0}'>{0}</option>", i);

    for (int i = 1; i <= 12; i++)
        months.AppendFormat("<option value='{0}'>{0}</option>", i);

    for (int i = beginYear; i <= endYear; i++)
        years.AppendFormat("<option value='{0}'>{0}</option>", i);

    daysList.InnerHtml = days.ToString();
    monthsList.InnerHtml = months.ToString();
    yearsList.InnerHtml = years.ToString();

    return string.Concat(daysList.ToString(), monthsList.ToString(), yearsList.ToString());
