Question

我将这些引号通过变量随机传递给段落，当一个新的引用＆＃34;按钮被堵住了。

我希望用户能够在Twitter上分享当前加载的报价。我尝试设置＆＃34;数据文本＆＃34;属性的值等于当前变量，但它似乎不起作用。我的代码到目前为止： http://codepen.io/RycerzPegaza/pen/YypZza

// HTML //

    <ul id="tweet"><a href="https://twitter.com/share" class="twitter-share-button" data-size="large" data-text="">share the quote</a></ul>

  <ul class="pager">
    <li onclick="randomquote()"><button type="button" class="btn btn-default"> a new qoute</button></li></ul></nav></div></div></body>

Answer 1

我从来没有使用过Twitter API，但是如果你在加载页面并运行twitter js之后动态更新它，那么我认为each方法无法正常工作。我会尝试使用Web Intents方法（参见页面底部），这意味着您可以在twitter共享网址中添加data-text的查询参数。一定要对文本进行url编码。每当报价发生变化时，您都需要更新text代码的href。

Answer 2

网络意图代码不起作用。

使用整个代码链接到codepen：http://codepen.io/RycerzPegaza/pen/NGpEGp

<a href="https://twitter.com/share?
      url=https%3A%2F%2Fdev.twitter.com%2Fweb%2Ftweet-button&
      via=twitterdev&
      related=twitterapi%2Ctwitter&
      hashtags=example%2Cdemo&
      text=custom%20share%20text">
    Tweet
    </a>

我尝试通过动态更改iframe src并将引号编码到url（为空格添加％20）来使用iframe，但它也不起作用：

// HTML //

    <iframe
 src="https://platform.twitter.com/widgets/tweet_button.html?size=l&text=custom%20share"
  width="140"
  height="100"
  title="Twitter Tweet Button"
  style="border: 0; overflow: hidden;">
</iframe>
