使用datetimepicker的多个实例以及日期之间的范围

Question

我正在尝试获取多个实例的“日期之间的范围”。 每个实例对都有一个不同的ID。 使用类添加了datetimepicker，这对于所有实例都是相同的：

var format = "d-m-Y H:i";
var startSelector = ".date_timepicker_start";
var endSelector = ".date_timepicker_end";

现在，我想获取被单击的字段的ID，然后从头开始替换，因此我具有匹配的end字段的ID，并使用此结果来获取值：

$(startSelector).datetimepicker( {
  format : format,
  onShow : function(ct) {
    var selectedid = $(this).attr('id');
    var selid = selectedid.replace("start", "end");
    var val = $("#"+selid).val();
    console.log('id: '+selectedid);
    var opts = {
      formatDate : "d-m-Y",
      maxDate : val ? val.split(' ')[0] : false
    };
    this.setOptions(opts);
  },

}）;

var selectedid = $（this）.attr（'id'）;但是返回undefined。 我也尝试过this.id等。有人知道吗？ 我可能正在俯视某事。

谢谢！

Answer 1

onShow方法中的$(this)引用datetimepicker div而不是输入。 因此，您会看到undefined

但是onShow方法还有其他参数

onShow：函数（日期，$ input，事件）

您可以对第二个参数使用，并通过$input.attr('id')获取ID

另外，您不需要这样的多个选择器。 你可以做这样的事情

<input type="text" class="datetimepicker" id="start" />
<input type="text" class="datetimepicker" id="end"/>

现在您只能使用一个选择器

$('.datetimepicker').datetimepicker({
  onShow: function(date, $input, event){
    alert($input.attr('id'));
  }
});

 var format = "dmY H:i"; // var startSelector = ".date_timepicker_start"; // var endSelector = ".date_timepicker_end"; var options = { format: format, onShow: function(date, $input, event) { alert($input.attr('id')); } }; /* Date Picker Validation JS */ $('.datetimepicker').datetimepicker(options);

Answer 2

而是先尝试使用jQuery each()函数对项目进行迭代，并在创建datetimepicker实例之前准备选项：

$(startSelector).each(function(){
    var $this=$(this); //local reference of jQuery object

    var selectedid = $this.attr('id');
    var selid = selectedid.replace("start", "end");
    var val = $("#"+selid).val();
    console.log('id: '+selectedid);

    $this.datetimepicker( {
        format : format,
        formatDate : "d-m-Y",
        maxDate : val ? val.split(' ')[0] : false
    });
});
