任何人有asp.net的MVC某些下拉列表日期选择器 [英] anybody has some dropdowns datepicker for asp.net mvc

问题描述

任何人知道我在哪里可以找到一个HTML帮助或东西是要生成一个从3下拉菜单组成的日期选择器？

anybody knows where can I find a html helper or something that is going to generate a datepicker composed from 3 dropdowns ?

推荐答案

这是我的小帮手。

本身的解释，我相信。可以调整，安排下拉菜单（月/日/年或日/月/年）的顺序，如果你使用.NET 4中，你可以把默认参数的名称。

Itself explanatory, I believe. Can be tweaked to arrange the order of the drop-downs (Month/Day/Year or Day/Month/Year), and if you're using .NET 4, you can put default parameters for the names.

/// <summary>

/// The parameters represent the value of the "name" attribute on the select control.

/// <param name="dayName">"Name" attribute of the day drop down list.</param>
/// <param name="monthName">"Name" attribute of the month drop down list.</param>
/// <param name="yearName">"Name" attribute of the year drop down list.</param>

public static string DatePickerDropDowns(this HtmlHelper html, string dayName, string monthName, string yearName)
{
    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);
    yearsList.Attributes.Add("name", yearName);

    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());
}
