单击推特按钮时获取数据属性. [英] GET data attr when twitter button is clicked.

问题描述

单击tweet按钮时，我需要访问data-url ="some link".

I need to access the data-url="some link" when the tweet button is clicked.

使用此代码:

twttr.events.bind('click', function(event) {

var tweeturl = $('.twitter-share-button').data("url");
var count = $('.twitter-share-button').data("count");
console.log(tweeturl, count);
});

但是控制台输出"undefined undefined".谁能告诉我为什么会这样以及如何解决?

However the console is outputting 'undefined undefined'. Can anyone tell me why this is happening and how to fix it?

非常感谢你们.

推荐答案

twitter API似乎正在更改您的链接并将其放入IFrame.因此，该链接不再可用.我可能需要更好地了解您的工作方式，才能正确回答您的问题.

It looks like the twitter API is changing your link and putting it into a IFrame. So the link is longer accessible. I may need to better understand what your after to properly answer your question.

但是您也可以将数据存储在foo元素中吗?

But could you store your data in the foo element as well?

twttr.events.bind('click', function(event) {
  var tweeturl = $('#foo').data("url");
  var count = $('#foo').data("count");
  console.log(tweeturl, count);
});
