Hide ui-datepicker-calendar based on element attribute

问题

I have multiple inputs on my page, all of which have jQuery UI's datepicker widget attached to them.

What I would like to do is show/hide the .ui-datepicker-calendar based on a data-calendar attribute on the input element.

For example:

<input type="text" data-calendar="false" />
<input type="text" data-calendar="false" />
<input type="text" data-calendar="true" />

So, the first two should not show the .ui-datepicker-calendar, but the last should.

I thought I could leverage the beforeShow event to set the display of the element, however, at the time the event fires, the .ui-datepicker-calendar does not yet exist:

$('input').datepicker({
  beforeShow: function(el, dp) {
    $('.ui-datepicker-calendar').toggle( !$(el).is('[data-calendar="false"]') );
  }
});

I've had a look at similar questions, and the answer is to use CSS to hide the .ui-datepicker-calendar element:

.ui-datepicker-calendar {
  display: none;
}

However, this won't work for me as I need to set the display property based on the element's data-calendar attribute.

Is there a simple way to achieve this? I had a look through the datepicker API but didn't come across anything.

Here's a simple base fiddle

Here's how I would like it to display, if data-calendar is false

回答1:

Having done some more searching, I came across this question which helped me solve my problem.

When the beforeShow event fires, add/remove a class on the #ui-datepicker-div element (this exists once the datepicker has been attached).

$('input').datepicker({
  beforeShow: function(el, dp) {
    $('#ui-datepicker-div').toggleClass('hide-calendar', $(el).is('[data-calendar="false"]'));
  }
});

Then, just add a style for .ui-datepicker-calendar within the .hide-calendar class:

.hide-calendar .ui-datepicker-calendar {
  display: none;
}

Here's a working fiddle

回答2:

Check the data attribute for each input element.

1) .data() - Method used to Store arbitrary data associated with the matched elements.

2) .each() - Method used to iterate objects of jQuery.

Try this.

$('input[type=text]').each(function(){
    alert($(this).data('calendar'));
    if($(this).data('calendar')){
        $(this).datepicker();
    }
});

Working Fiddle

From your comments,

$('input').datepicker();
$('input[type=text]').each(function () {
    if ($(this).data('calendar')) {
        $(this).datepicker();
    }
    else{
        $(this).datepicker('destroy');  //Removes the datepicker functionality 
    }
});
