Are you tired of struggling to create a seamless user experience for your website visitors when dealing with PDF files? Do you want to learn the secrets of redirecting to a specific page on button click in HTML, especially when it comes to PDF files with a type of “application/pdf”? Look no further! In this comprehensive guide, we’ll take you by the hand and walk you through the process of achieving this feat with ease.

Understanding the Basics: What is an iframe and an embed?

Before we dive into the nitty-gritty of redirecting to a page on button click, it’s essential to understand the basics of iframes and embeds in HTML.

What is an iframe?

An iframe (short for inline frame) is an HTML element that allows you to embed another HTML document inside a web page. It’s essentially a container that holds a separate document, which can be an HTML file, a PDF, or even another website.

<iframe src="https://example.com" width="100%" height="500px"></iframe>

What is an embed?

An embed element, on the other hand, is used to incorporate external content, such as a PDF file, into a web page. It’s similar to an iframe, but it’s specifically designed for embedding multimedia content, like videos or PDFs.

<embed src="example.pdf" type="application/pdf" width="100%" height="500px"></embed>

Why Do We Need to Redirect to a Specific Page on Button Click?

In many scenarios, you might want to redirect users to a specific page or section within a PDF file when they click a button. This could be due to various reasons, such as:

• Providing a seamless user experience: By redirecting users to a specific page, you can ensure they land exactly where they need to be, without having to navigate through the entire PDF.
• Enhancing accessibility: Redirecting to a specific page can be particularly helpful for users with disabilities, as it allows them to access the desired information quickly and easily.
• Streamlining workflows: In certain cases, redirecting to a specific page can help streamline workflows, especially when dealing with complex documents or forms.

How to Redirect to a Page on Button Click in HTML for PDF Files

Now that we’ve covered the basics, let’s dive into the meat of the matter! To redirect to a specific page on button click in HTML for PDF files, you’ll need to follow these steps:

1. First, create an iframe or embed element to display the PDF file:

   <iframe src="example.pdf" width="100%" height="500px"></iframe>

   Or

   <embed src="example.pdf" type="application/pdf" width="100%" height="500px"></embed>

2. Next, create a button element with an onclick event that will trigger the redirection:

   <button onclick="gotoPage(2)">Go to Page 2</button>

3. Now, add a JavaScript function that will handle the redirection:

   <script>
         function gotoPage(pageNumber) {
           var iframe = document.getElementById('pdf-iframe');
           iframe.src = 'example.pdf#page=' + pageNumber;
         }
       </script>

   Note that we’re using the #page= anchor to specify the page number we want to redirect to.

4. Finally, add an ID to your iframe or embed element so that we can target it with JavaScript:

   <iframe id="pdf-iframe" src="example.pdf" width="100%" height="500px"></iframe>

An Example in Action

Here’s a complete example that demonstrates how to redirect to a specific page on button click in HTML for a PDF file:

<script>
  function gotoPage(pageNumber) {
    var iframe = document.getElementById('pdf-iframe');
    iframe.src = 'example.pdf#page=' + pageNumber;
  }
</script>
