Hướng dẫn tạo nút chia sẻ bài viết dạng popup

Tạo nút chia sẻ bài viết blogspot với popup chia sẻ với các liên kết chia sẻ bài viết lên các trang mạng xã hội: Twitter, Facebook, Pinterest, Linkedin.

Popup chia sẻ với các liên kết chia sẻ bài viết lên các trang mạng xã hội: Twitter, Facebook, Pinterest, Linkedin.

Trước khi đi vào bài hướng dẫn, mình giới thiệu qua về điều kiện cần để tạo được nút chia sẻ bài viết
Blog đã xuất bản bài viết
Bài viết cần có tiêu đề, upload ít nhất một ảnh và có nội dung bằng văn bản đẻ có đoạn trích tóm tắt
Định cấu hình tiện ích bài đăng trên blog cho phép chia sẻ
Nút chia sẻ phải được đặt trong vòng lặp của post
Cần tạo ứng dụng Facebook để lấy id và tên ứng dụng
Theme cần có thư viện link jquery

Hướng dẫn tạo nút chia sẻ và các liên kết chia sẻ bài viết lên các trang mạng xã hội

Bước 1: Đặt nút chia sẻ trong vòng lặp post vào bất kỳ vị trí nào và tại bất kỳ trang nào


Nếu theme có widget Blog1 version='1'

<b:if cond='data:widgets.Blog.first.allBylineItems.share'>
  <span class='share share-this-post' expr:aria-label='data:messages.share' expr:data-href='data:post.url.canonical' expr:data-image='resizeImage(data:post.firstImageUrl, 1200, &quot;1200:630&quot;)' expr:data-postId='data:post.id' expr:data-snippets='data:post.snippet' expr:title='data:messages.share' role='button' tabindex='0'><data:messages.share/></span>
</b:if>

Nếu theme có widget Blog1 version='2'

<b:if cond='data:widgets.Blog.first.allBylineItems.share'>
  <span class='share share-this-post' expr:aria-label='data:messages.share' expr:data-href='data:post.url.canonical' expr:data-image='resizeImage(data:post.featuredImage, 1200, &quot;1200:630&quot;)' expr:data-postId='data:post.id' expr:data-snippets='data:post.snippets.short' expr:title='data:messages.share' role='button' tabindex='0'><data:messages.share/></span>
</b:if>

Bước 2: Đặt script trước thẻ đóng </body>

<script asyns='asyns' defer='defer' src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js'/>
<b:if cond='data:widgets.Blog.first.allBylineItems.share'>
  <script>

        share:&quot;<data:messages.share/>&quot;,     
        shareheader:&quot;Chia sẻ nội dung này qua&quot;,
        copy:&quot;Sao chép liên kết&quot;,
        facebook:&quot;<b:eval expr='data:blog.sharing.platforms[1].shareMessage'/>&quot;,
        twitter:&quot;<b:eval expr='data:blog.sharing.platforms[3].shareMessage'/>&quot;,
        pinterest:&quot;<b:eval expr='data:blog.sharing.platforms[4].shareMessage'/>&quot;,
        linkedin:&quot;Chia sẻ với Linkedin&quot;,
        email:&quot;Gửi bài qua Email&quot;,
        close:&quot;Đóng&quot;     
      }
    }
