javascript - 脚本代码片段显示在博客文章摘要中

Question

最近我的博客Sample批准了 Adsense，所以我开始将广告放在帖子的顶部。但这会导致广告代码显示在帖子摘要中，如下所示请看这个

请帮我弄清楚如何删除它。

Java 脚本代码

<script type='text/javascript'>
//<![CDATA[
//Post Thumbnail Setting
var TemplateismSummary = {
    displayimages: false,
    imagePosition: 'left',
    Widthimg: 200,
    Heightimg: 0,
    noThumb: 'https://lh3.googleusercontent.com/-GRP8IcURRsw/T9MjiNWXUcI/AAAAAAAAB88/QEDpDHxI55o/s1600/no-thumb.jpg',
    SummaryWords: 21,
    wordsNoImg: 20,
    skipper: 0,
    DisplayHome: true,
    DisplayLabel: true
};

您将需要使用新引入的 snippet运算符(operator)。这是 Blogger 用于从 HTML 字符串生成片段的 native 方法(在我们的示例中，这是完整的帖子内容)。设置选项linebreaks和links至false需要完成从通过此运算符生成的代码片段中删除所有 HTML 标签。替换<data:post.body/>的实例使用以下代码 -

<b:if cond='data:blog.pageType not in {"static_page", "item"}'>
  <b:eval expr='snippet(data:post.body, {length: 450, linebreaks: false, links: false})' />
<b:else/>
  <data:post.body/>
</b:if>

有关 snippet 的所有选项的信息运算符-

snippet(string, options)

Produces a short snippet from an HTML string.

options: Object specifying the snippeting options, which are:

• links: boolean for whether to preserve anchors/links in the snippet.Defaults to true.
• linebreaks: boolean for whether to preserve linebreaks (tags) in thesnippet. Defaults to true.
• ellipsis: boolean for whether to append an ellipsis to the end ofthe snippet. Defaults to true.
• length: Number specifying the maximum length of the snippet.
