我的选择列表中有2个optgroup (类别和子类别)并且我试图显示optgroup并在选择子类别时隐藏其他。
例如,如果我选择类别(运动,音乐)在子类别我仅显示运动和音乐
中我尝试了以下代码,但不起作用
谢谢
$("#custom_form_names_category").on("change", function() {
var selectedVal = $(this).find("option:selected").text();
console.log(selectedVal);
$('#custom_form_names_subcategorie > [aria-label="' + selectedVal + '"]')
.show()
.siblings("optgroup")
.css("display", "none");
});
$(".js-select2").select2({
closeOnSelect: false,
allowClear: true,
tags: true,
dropdownCssClass: "beforecheckbox"
});

您不能与选项组进行交互,但要与select2的渲染结果进行交互:
测试:
$ ('#select2-custom_form_names_subcategorie-results > [aria-label="' + selectedVal + '"]').show().siblings("li").css('display', 'none');
