How to read files in HTML

Get straight to the point:

HTML itself does not provide the ability to directly read files.

Detailed explanation:

In order to read the file content, you need to use JavaScript, a server-side language or a third-party library. Here are some common methods:

  • XMLHttpRequest: is a way to load files asynchronously without refreshing the page. Syntax: var xhr = new XMLHttpRequest();.
  • fetch(): is a modern replacement for XMLHttpRequest with a simpler syntax. Syntax: fetch('myFile.txt').then((response) => response.text());.
  • FileReader: Used to read local files, only available after user authorization. Syntax: var reader = new FileReader(); reader.onload = function() { ... }; reader.readAsText('myFile.txt');.
  • Server-side languages: For example, PHP or Node.js, files can be read through file system functions. For example: $content = file_get_contents('myFile.txt');.

Third-party libraries:

There are also many third-party libraries that can simplify the file reading process, such as:

  • jQuery.get(): Use XMLHttpRequest to load files asynchronously. Syntax: $.get('myFile.txt', function(data) { ... });.
  • axios: Library for making HTTP requests. Syntax: axios.get('myFile.txt').then((response) => response.data);.
  • fs-extra: Node.js library, providing file system related functions. Syntax: const fs = require('fs-extra'); const content = fs.readFileSync('myFile.txt');.

Which method you choose depends on your specific needs and environment.

Scrapy asynchronous loading implementation method based on Ajax Scrapy asynchronous loading implementation method based on Ajax Jun 22, 2023 pm 11:09 PM

Scrapy is an open source Python crawler framework that can quickly and efficiently obtain data from websites. However, many websites use Ajax asynchronous loading technology, making it impossible for Scrapy to obtain data directly. This article will introduce the Scrapy implementation method based on Ajax asynchronous loading. 1. Ajax asynchronous loading principle Ajax asynchronous loading: In the traditional page loading method, after the browser sends a request to the server, it must wait for the server to return a response and load the entire page before proceeding to the next step.

Detailed explanation of the suspend function in Vue3: Optimizing asynchronous data loading In modern websites and applications, asynchronous data loading is essential. However, due to the instability of network connection speeds, asynchronous data loading may cause delays and freezes in the user interface. To solve this problem, Vue3 introduces a new suspend function to optimize asynchronous data loading. The suspense function is a new feature in Vue3. It allows you to display a loading UI when loading data asynchronously until asynchronously.
