Question

我正在尝试从以下标记中删除RT。我试过了

 $('#tweet').text( $('#tweet').text().replace("RT ", ''));

但它只从第一个div中删除了RT。有什么想法吗？

<div class="fslider" data-animation="slide" data-arrows="false" data-pagi="false">
  <div class="flexslider">
    <div class="slider-wrap">
      <div class="slide" id="tweet">RT  A new empowerment group, the Business Economic Empowerment Forum, has been launched in Zim aiming to promote business and ec…<span class="twitter_date"><br>
        </span></div>
      <div class="slide" id="tweet">RT  Alexander Forbes extends footprint to Zim through its acquisition of a significant stake in African Actuarial Consultants<span class="twitter_date"><br>
        </span></div>
      <div class="slide" id="tweet">RT  Nigeria &amp;amp; Morocco sign agreements on a regional gas pipeline which will see Nigeria providing gas to countries in West Africa<span class="twitter_date"><br>
        </span></div>
    </div>
  </div>
</div>

Answer 1

id值必须在页面上是唯一的，因此第一步是更改标记以使用tweet类而不是id：< / p>

<div class="fslider" data-animation="slide" data-arrows="false" data-pagi="false">
  <div class="flexslider">
    <div class="slider-wrap">
      <div class="slide tweet">RT  A new empowerment group, the Business Economic Empowerment Forum, has been launched in Zim aiming to promote business and ec…<span class="twitter_date"><br>
        </span></div>
      <div class="slide tweet">RT  Alexander Forbes extends footprint to Zim through its acquisition of a significant stake in African Actuarial Consultants<span class="twitter_date"><br>
        </span></div>
      <div class="slide tweet">RT  Nigeria &amp;amp; Morocco sign agreements on a regional gas pipeline which will see Nigeria providing gas to countries in West Africa<span class="twitter_date"><br>
        </span></div>
    </div>
  </div>
</div>

然后，您需要使用text's callback：

循环遍历它们

$(".tweet").text(function(_, text) {
    return text.replace("RT ", "");
});

请注意，奇怪的是，文本是回调的第二个参数。

直播示例：

＆＃13;

$(".tweet").text(function(_, text) {
    return text.replace("RT ", "");
});

＆＃13;

<div class="fslider" data-animation="slide" data-arrows="false" data-pagi="false">
  <div class="flexslider">
    <div class="slider-wrap">
      <div class="slide tweet">RT  A new empowerment group, the Business Economic Empowerment Forum, has been launched in Zim aiming to promote business and ec…<span class="twitter_date"><br>
        </span></div>
      <div class="slide tweet">RT  Alexander Forbes extends footprint to Zim through its acquisition of a significant stake in African Actuarial Consultants<span class="twitter_date"><br>
        </span></div>
      <div class="slide tweet">RT  Nigeria &amp;amp; Morocco sign agreements on a regional gas pipeline which will see Nigeria providing gas to countries in West Africa<span class="twitter_date"><br>
        </span></div>
    </div>
  </div>
</div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

＆＃13;

请注意，replace无论文本在何处都会替换RT，并且只会替换第一个return text.replace(/^RT /, "");。要使其专门只替换文本开头的一个，如果有的话，将其更改为

...其中/^RT +/表示＆＃34;开始输入。＆＃34;您甚至可以使用$(".tweet").text(function(_, text) { return text.replace(/^RT +/, ""); });，因此您可以替换它后面的所有空格而不只是一个。

直播示例：

＆＃13;

<div class="fslider" data-animation="slide" data-arrows="false" data-pagi="false">
  <div class="flexslider">
    <div class="slider-wrap">
      <div class="slide tweet">RT  A new empowerment group, the Business Economic Empowerment Forum, has been launched in Zim aiming to promote business and ec…<span class="twitter_date"><br>
        </span></div>
      <div class="slide tweet">RT  Alexander Forbes extends footprint to Zim through its acquisition of a significant stake in African Actuarial Consultants<span class="twitter_date"><br>
        </span></div>
      <div class="slide tweet">RT  Nigeria &amp;amp; Morocco sign agreements on a regional gas pipeline which will see Nigeria providing gas to countries in West Africa<span class="twitter_date"><br>
        </span></div>
    </div>
  </div>
</div>
