在引导日期选择器中禁用过去的日期

Question

我使用了源自以下内容的日期输入表单：

Youderian, C.如何将日期选择器添加到 Bootstrap 表单。形式登。[博客]。2015-10-27。

但我无法禁用过去的日期。我尝试了以下方法；根据GitHub 中的一个问题，但它对我不起作用。

$(document).ready(function() {
  var date_input = $('input[name="date"]'); //our date input has the name "date"
  var container = $('.bootstrap-iso form').length > 0 ? $('.bootstrap-iso form').parent() : "body";
  date_input.datepicker({
    format: 'mm/dd/yyyy',
    container: container,
    todayHighlight: true,
    autoclose: true,
  })
})
$(function() {
  var nowDate = new Date();
  var today = new Date(nowDate.getFullYear(), nowDate.getMonth(),
    nowDate.getDate(), 0, 0, 0, 0);
  $('#date').datepicker({
    startDate: today
  });
})

您可以startDate在第一次将其转换为日期选择器字段时将其添加到配置中，也可以使用setStartDate.

选择两者中的任何一个。

$(document).ready(function() {
  var dateInput = $('input[name="date"]'); // Our date input has the name "date"
  var container = $('.bootstrap-iso form').length > 0 ? $('.bootstrap-iso form').parent() : 'body';
  dateInput.datepicker({
    format: 'mm/dd/yyyy',
    container: container,
    todayHighlight: true,
    autoclose: true,
    startDate: truncateDate(new Date()) // <-- THIS WORKS
  });

  $('#date').datepicker('setStartDate', truncateDate(new Date())); // <-- SO DOES THIS
});

function truncateDate(date) {
  return new Date(date.getFullYear(), date.getMonth(), date.getDate());
}
