使用 data-id 从页面重定向

  • 772

有一个很具体的情况，有一定数量的帖子（比如10个），还有两个按钮：删除，查看。我们需要View按钮来使用data-id重定向用户，但这很好，但按钮位置很糟糕。此外，每个帖子都有一个带有自己id的图像，也许以这种方式重定向用户会更好？

// viewLinkID - значение атрибута data-id

$('span').each(function() {
  $(this).append('<button><a href=' + viewLinkID + '> [ View ]</button>')
}

顺便说一句，获取data-id的最佳方法是什么？通过方法data()还是attr()？如果代码中有任何错误，请指出并纠正我。

最终，“删除”按钮应该有一个“查看”按钮，可以重定向到当前帖子（在当前 ID/号码下发布）。

目标是首先<div>获取 的值data-id⁣，并使用该值在“删除”按钮旁边创建一个按钮，并为每个<div>.

    更好通过data()，更清晰

    $('div[data-id]').each(function() {
  let viewLinkID = $(this).data('id');
  $(this).append('<button><a href="post/'+ viewLinkID +'"> [ View ]</button>')
})
