For PDFs, libraries like PDF.js can help with rendering and basic interactions, while more advanced features might require server-side processing or specialized APIs. A simple example of how one might implement a text highlight feature using JavaScript and PDF.js could look something like this: Rick Ross - Teflon Don -album - 2010-
// Assuming pdfDoc is your PDF document loaded via PDF.js pdfDoc.getPage(1).then(function(page) { page.getTextContent().then(function(textContent) { // Do something with the text, like adding a highlight const highlightedText = textContent.strings[0]; // Example string // Add highlighting logic here }); }); This snippet is highly simplified and represents just a starting point. Implementing the features described would require a much more detailed approach, including UI considerations, user authentication, and data storage solutions. Ngintip Abg Mandi Link [SAFE]
