当我在 jQuery 日期选择器中的 select 未来或过去日期时，如何显示模式弹出窗口？

Question

当我在jQuery日期选择器中 select 未来和过去日期时如何显示模式弹出窗口。 我正在使用 v1.12.1 日期选择器和jQuery v3.3.1

我在互联网上找到了一种方法，但这不是jQuery的最新版本。 所以它对我不起作用..

示例小提琴在这里

这是我的示例小提琴

 $("#datepicker").datepicker(); $("#datepicker").change(function(){ var date = $(this).val(); $('<div>' + date + '</div>').dialog(); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <input type="text" id="datepicker">

注意：模态弹出窗口如“您是 select 未来日期，您要继续吗？是或否。” 像那样。

Answer 1

嗨，您可以使用普通的 java-script 模式弹出窗口来显示您的 output。

<div id="datepicker" style="font: 80% 'Trebuchet MS', sans-serif;"></div>
<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <p id="body">Some text in the Modal..</p>
  </div>

</div>

---

 $("#datepicker").datepicker();

$("#datepicker").change(function(){
     var date = $(this).val();
     $("#body").html("You have selected future date:"+ date);
     modal.style.display = "block";
});

// Get the modal
var modal = document.getElementById("myModal");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];



// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}

function isFutureDate(idate){
var today = new Date().getTime();
idate = new Date(idate).getTime();
return (today - idate) < 0 ? true : false;
}

这是工作示例
