将 JSON 日期解析为 Bootstrap 日期选择器控件

Question

以下 sn-ps 显示了一个引导日期选择器控件。我有一个 JSON 数组，我正在显示它的解析结果，我如何将它安装到输入文本框并保持它与日期选择器的兼容性，这意味着当您单击该字段时，您将看到下拉日历中选择的日期

我尝试解析日期，例如 $.datepicker.parseDate('d/m/yy', new Date((obj[0].DOB.match(/\d+/)[0] * 1))); 但没有用 谢谢

 d='[{"DOB":"\/Date(1512460800000)\/"}]'
 var obj = $.parseJSON(d)
 console.log(new Date((obj[0].DOB.match(/\d+/)[0] * 1)))

Answer 1

这样做： date_input.datepicker("update", this_date); 将更新日期选择器中的日期。由于它接受Date 对象，它将保持日期与日期选择器兼容。

$(document).ready(function() {
  d = '[{"DOB":"\/Date(1512460800000)\/"}]'
  var obj = $.parseJSON(d)
  var this_date = new Date((obj[0].DOB.match(/\d+/)[0] * 1))
  console.log(new Date((obj[0].DOB.match(/\d+/)[0] * 1)))


  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";
  var options = {
    format: 'mm/dd/yyyy',
    container: container,
    todayHighlight: true,
    autoclose: true,
  };
  date_input.datepicker(options);
  date_input.datepicker("update", this_date);
})
