如何更改输入类型=“ datetime-local”的格式？

Question

我想更改占位符或输入类型=“ datetime-local”的格式 如何使用普通的javascript或html输入标签将其从mm/dd/yyyy更改为dd/mm/yyyy？

Answer 1

默认以dd / mm / yyyy格式显示

<input type="datetime-local" name="date">

Answer 2

您可以这样：

function nowAsDuration(){
    return moment.duration({
        hours:   moment().hour(),
        minutes: moment().minute(),
        seconds: moment().second()
    });
}


$("input").on("change", function() {
    var a = moment(this.value);
    var b = nowAsDuration();
    var c = a.add(b);
    
        
    this.setAttribute("my-date", c.format( this.getAttribute("my-date-format") )
    )
}).trigger("change")

input {
    position: relative;
    width: 250px; height: 20px;
    color: white;
}

input:before {
    position: absolute;
    top: 3px; left: 3px;
    content: attr(my-date);
    display: inline-block;
    color: black;
}

<input type="date" my-date="" my-date-format="DD/MM/YYYY, hh:mm:ss" value="2015-08-09">

Answer 3

codepen Simple Bootstrap datepicker中有一个类似的示例。 使用此功能，您可以根据需要以任何格式显示日期时间。 上面示例中的唯一问题是，由于输入类型为 text 。

，因此用户可以在输入字段中输入任何字符。

我刚刚添加了 onkeydown =“ return false” ，这样用户将无法通过单击输入字段直接输入数据，并且还向其中添加了CSS删除闪烁的光标。

注意：在运行代码段时，单击“整页”或使用“箭头键”查看整个日历。

希望这会有所帮助！

$(function() {
  var bindDatePicker = function() {
    $(".date").datetimepicker({
      format: 'DD/MM/YYYY hh:mm A',
      icons: {
        time: "fa fa-clock-o",
        date: "fa fa-calendar",
        up: "fa fa-arrow-up",
        down: "fa fa-arrow-down"
      }
    }).find('input:first').on("blur", function() {
      // check if the date is correct. We can accept dd-mm-yyyy and yyyy-mm-dd.
      // update the format if it's yyyy-mm-dd
      var date = parseDate($(this).val());

      if (!isValidDate(date)) {
        //create date based on momentjs (we have that)
        date = moment().format('DD/MM/YYYY hh:mm A');
      }

      $(this).val(date);
    });
  }

  var isValidDate = function(value, format) {
    format = format || false;
    // lets parse the date to the best of our knowledge
    if (format) {
      value = parseDate(value);
    }

    var timestamp = Date.parse(value);

    return isNaN(timestamp) == false;
  }

  var parseDate = function(value) {
    var m = value.match(/^(\d{1,2})(\/|-)?(\d{1,2})(\/|-)?(\d{4})$/);
    if (m)
      value = m[5] + '-' + ("00" + m[3]).slice(-2) + '-' + ("00" + m[1]).slice(-2);

    return value;
  }

  bindDatePicker();
});

input[type="text"]{
    color : transparent;
    text-shadow : 0 0 0 #000;
}

我对Vue.js很陌生。我尝试了一些东西，请看看这个...

// Initialize as global component
Vue.component('date-picker', VueBootstrapDatetimePicker);

// Using font-awesome 5 icons
$.extend(true, $.fn.datetimepicker.defaults, {
  icons: {
    time: 'far fa-clock',
    date: 'far fa-calendar',
    up: 'fas fa-arrow-up',
    down: 'fas fa-arrow-down',
    previous: 'fas fa-chevron-left',
    next: 'fas fa-chevron-right',
    today: 'fas fa-calendar-check',
    clear: 'far fa-trash-alt',
    close: 'far fa-times-circle'
  }
});

new Vue({
  el: '#app',
  data: {
    date: null,
    options: {
      // https://momentjs.com/docs/#/displaying/
      format: 'DD/MM/YYYY hh:mm A',
      useCurrent: false,
      showClear: true,
      showClose: true,
    }
  },
});
