获取数据ID＆＃34;未定义＆＃34;

Question

我使用了floatingMenu ，我希望获得带有Data-id的身份证号码，但我无法获取按钮的ID号

输出：

example.com/?id=undefined

为什么我收到此错误？

var myDiv = document.querySelector('.designer-actions');

$.floatingMenu({
    selector: '.designer-actions a[data-action="show-actions-menu"]',

更新回答：

你需要遍历数组：

$('.designer-actions a').each(function(){
  idNo = $(this).data('idno');
  $.floatingMenu({
      selector: '.designer-actions a[data-action="show-actions-menu"]',
      items: [{
        title: 'Open',
        action: 'https://example.com/?id=' + idNo
      }, ]
  });
});
