Question

我有这个脚本来制作自定义选择框。我正在选择Ul和LI重叠。但是当select具有名为“disabled”的属性时，我不想打开UL LI。有人可以帮我这么做吗？

grid-template-rows: 60px 1fr

HTML

// Iterate over each select element
$('select').each(function () {

    // Cache the number of options
    var $this = $(this),
        numberOfOptions = $(this).children('option').length;

    // Hides the select element
    $this.addClass('s-hidden');

    // Wrap the select element in a div
    $this.wrap('<div class="select"></div>');

    // Insert a styled div to sit over the top of the hidden select element
    $this.after('<div class="styledSelect"></div>');

    // Cache the styled div
    var $styledSelect = $this.next('div.styledSelect');

    // Show the first select option in the styled div
    $styledSelect.text($this.children('option').eq(0).text());

    // Insert an unordered list after the styled div and also cache the list
    var $list = $('<ul />', {
        'class': 'options'
    }).insertAfter($styledSelect);

    // Insert a list item into the unordered list for each select option
    for (var i = 0; i < numberOfOptions; i++) {
        $('<li />', {
            text: $this.children('option').eq(i).text(),
            rel: $this.children('option').eq(i).val()
        }).appendTo($list);
    }

    // Cache the list items
    var $listItems = $list.children('li');

    // Show the unordered list when the styled div is clicked (also hides it if the div is clicked again)
    $styledSelect.click(function (e) {
        e.stopPropagation();
        $('div.styledSelect.active').each(function () {
            $(this).removeClass('active').next('ul.options').hide();
        });
        $(this).toggleClass('active').next('ul.options').toggle();
    });

    // Hides the unordered list when a list item is clicked and updates the styled div to show the selected list item
    // Updates the select element to have the value of the equivalent option
    $listItems.click(function (e) {
        e.stopPropagation();
        $styledSelect.text($(this).text()).removeClass('active');
        $this.val($(this).attr('rel'));
        $list.hide();
        /* alert($this.val()); Uncomment this for demonstration! */
    });

    // Hides the unordered list when clicking outside of it
    $(document).click(function () {
        $styledSelect.removeClass('active');
        $list.hide();
    });

});

Answer 1

使用已启用的选择器：

$('select':enabled).each(function () {

}

请参阅演示here

Answer 2

.slbSelect.disabled {
  .styledSelect {
    background: lighten($disable, 14%);
    cursor: default;
    &:after {
      @include triangle(down, 6px, $disable);
    }
  }
}

if($this.is(':disabled')){
     $this.parent().addClass('disabled');
     $list.remove();
}

这解决了我的问题。谢谢大家。
