This JavaScript code enhances your HTML webpage by enabling it to read a selected text file and display its content dynamically. The code utilizes the FileReader API<\/a> to handle the selected file, checks if it’s a text file, and then renders the content in the designated HTML area. This functionality allows you to effortlessly showcase text files on your webpage, offering a seamless way to share and present textual information.<\/p>\n

You can use this code on websites where you want users to interactively view text files. It’s handy for sharing documents, instructions, or any text-based content. One major benefit is its simplicity\u2014users can select a file, and it promptly displays the text on the webpage, making information easily accessible without additional downloads or plugins.<\/p>\n

How to Read Text File and Display In HTML Using JavaScript<\/h2>\n

1. Start by creating an HTML file and include the necessary structure. Copy the following HTML code into your <body><\/code> section. This establishes a basic webpage with a file input element and an area to display text.<\/p>\n

<div id=\"page-wrapper\">\r\n\r\n\t\t<h1>Text File Reader<\/h1>\r\n\t\t<div>\r\n\t\t\tSelect a text file: \r\n\t\t\t<input type=\"file\" id=\"fileInput\">\r\n\t\t<\/div>\r\n\t\t<pre id=\"fileDisplayArea\"><pre>\r\n\r\n\t<\/div><\/pre>\n
2. Now, copy the CSS code into your <style><\/code> or external stylesheet. This ensures a clean and visually appealing layout for your file reader.<\/p>\n
html {\r\n  font-family: Helvetica, Arial, sans-serif;\r\n  font-size: 100%;\r\n  \r\n}\r\n\r\n#page-wrapper {\r\n  width: 600px;\r\n  background: #FFF;\r\n  padding: 1em;\r\n  margin: 1em auto;\r\n  min-height: 300px;\r\n  border-top: 5px solid #69c773;\r\n  box-shadow: 0 2px 10px rgba(0,0,0,0.8);\r\n}\r\n\r\nh1 {\r\n\tmargin-top: 0;\r\n}\r\n\r\nimg {\r\n  max-width: 100%;\r\n}\r\n\r\n#fileDisplayArea {\r\n  margin-top: 2em;\r\n  width: 100%;\r\n  overflow-x: auto;\r\n}<\/pre>\n
3. Finally, copy the following JavaScript code into a <script><\/code> tag or an external JavaScript file. This script allows your webpage to read and display the content of a selected text file.<\/p>\n
window.onload = function() {\r\n\t\tvar fileInput = document.getElementById('fileInput');\r\n\t\tvar fileDisplayArea = document.getElementById('fileDisplayArea');\r\n\r\n\t\tfileInput.addEventListener('change', function(e) {\r\n\t\t\tvar file = fileInput.files[0];\r\n\t\t\tvar textType = \/text.*\/;\r\n\r\n\t\t\tif (file.type.match(textType)) {\r\n\t\t\t\tvar reader = new FileReader();\r\n\r\n\t\t\t\treader.onload = function(e) {\r\n\t\t\t\t\tfileDisplayArea.innerText = reader.result;\r\n\t\t\t\t}\r\n\r\n\t\t\t\treader.readAsText(file);\t\r\n\t\t\t} else {\r\n\t\t\t\tfileDisplayArea.innerText = \"File not supported!\"\r\n\t\t\t}\r\n\t\t});\r\n}<\/pre>\n
