jQuery datepicker - 在init之后更改.ui-datepicker-calendar的显示

Question

How can I change the css display attribute of the ui-datepicker-calendar class after the datepicker has already been initialized? I have a html form with a selectable checkbox from which I want to toggle the display of this table. I've tried the following:

HTML sample:

 <div class="row">
  <div class="adddescr"><label for="date">Zeitraum:</label></div>
  <div class="addinput" id="date"><input type="text" id="datefrom" name="datefrom" class="date" /> - <input type="text" id="dateto" name="dateto" class="date" /></div>
 </div>
 <div class="row">
  <div class="addinput"><label><input type="checkbox" id="dateplanedcheck" /> grobe Planung</label></div>
 </div>

JS first approach:

 <script>
  $(document).ready(function() {
   $("#datefrom, #dateto").datepicker({ dateFormat: "dd.mm.yy",

   [...]

    beforeShow: function(input, inst) {
     if ($("#dateplanedcheck").is(':checked')) {
      $(".ui-datepicker-calendar").css("display", "none");
    }}
   });

   [...]

  });
 <script>

The beforeShow is called, but the calender is still displayed.

JS second approach:

 <script>
  $(document).ready(function() {

  [....]

   $("#dateplanedcheck").change(function() {
    if ($(this).is(':checked')) {
      $(".ui-datepicker-calendar").css("display", "none");
    }
   });
  });
 </script>

What am I missing? Does this even work with jQuery? Thanks in advance!

Answer 1

So you want to NOT show the calendar if the checkbox is checked?

Just return false; in the beforeShow.

$("#datefrom, #dateto").datepicker({
    dateFormat: "dd.mm.yy",
    beforeShow: function(input, inst) {
        if ($("#dateplanedcheck").prop('checked')) {
            return false;
           }

    }
});

Answer:

Still displaying the calendar but making it invisible:

BeforeShow can't access the ui-datepicker-calendar on the table because it hasn't been rendered yet. Apply a class like $(inst.dpDiv).addClass('calendar-off') and then have the style .calendar-off table.ui-datepicker-calendar { display none; } .calendar-off table.ui-datepicker-calendar { display none; } like this: http://jsfiddle.net/JzbPD/4
