您如何使用 JS 或 jQuery 从引导 datetimepicker 中控制台记录日期

Question

当我单击按钮时，我想要console.log插入输入中的日期和时间，但是当我尝试时，我只会得到“未定义”。

      $('#picker-start').datetimepicker({

        timepicker: true,

        datepicker: true,

        format: 'y-m-d H:i',

        onShow: function(ct) {

          this.setOptions({

            maxDate: $('#picker-end').val() ? $('#picker-end').val() : false

          })

        }

      })

      $('#picker-end').datetimepicker({

        timepicker: true,

        datepicker: true,

        format: 'y-m-d H:i',

        onShow: function(ct) {

          this.setOptions({

            minDate: $('#picker-start').val() ? $('#picker-start').val() : false

          })

        }

      });

    <div class="form-group">

        <label for="">Start Date</label>

        <input type="text" id="picker-start" class="form-control">

        <label for="">Due Date</label>

        <input type="text" id="picker-end" class="form-control">

        <button type="submit" id="btn-time">get date</button>

      </div>

Answer 1

HTML：<div class="form-group">&nbsp; &nbsp; <label for="">Start Date</label>&nbsp; &nbsp; <input type="text" id="picker-start" class="form-control">&nbsp; &nbsp; <label for="">Due Date</label>&nbsp; &nbsp; <input type="text" id="picker-end" class="form-control">&nbsp; &nbsp; <button type="button" id="btn-time">get date</button></div>jQuery：$('#btn-time').on("click", function() {&nbsp; &nbsp; var startDate = $('#picker-start').val()&nbsp; &nbsp; var endDate = $('#picker-end').val()&nbsp; &nbsp; console.log(startDate+' - '+endDate);});
