Ajax cooperates with Spring to implement file upload function code
Recently, I have been developing a web surface page that can upload images to the server. Here I will share with you the requirements and implementation ideas as well as the ajax source code. Friends who are interested in ajax can refer to the Ajax implementation with Spring File uploadfunction!
Due to project needs, develop a web form page that can upload images to the server.
1. Requirements
Web form page, you can upload pictures and other text information through the form.
2. The process of uploading pictures
I have never done this type of page before, so I can query the information. It is found that a common practice is to first upload the image to a file directory on the server side, and the server returns the storage path of the image to the front desk; then, the front desk submits the image storage path and other form information to the server, and all form information is stored in the database.
3. Method
Due to project needs, I will introduce two methods of image uploading here. The first one is to use ajax to directly upload an image. Upload; the second is to first cut the image into smaller files at the front desk, and then use ajax to upload the images to the server respectively, and the server will splice the files. (Method 2 is suitable for uploading larger files) Below I will introduce the two methods respectively.
Method 1: Directly upload the
1 html page
<pre name="code" class="html"><!DOCTYPE html> <head></head> <body> <form id="uploadForm" action="/PicSubmit/form" method="post" enctype="multipart/form-data" onsubmit="return submit_check()" class="bootstrap-frm" >
<input>
<input><input><input>" /><input> <input>

Python vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AMThe main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.
Python vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AMWhether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.
Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AMPython and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

Backend example: Create a Node.js server.
Python vs. JavaScript: Which Language Should You Learn?May 03, 2025 am 12:10 AMChoosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.
JavaScript Frameworks: Powering Modern Web DevelopmentMay 02, 2025 am 12:04 AMThe power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.
The Relationship Between JavaScript, C , and BrowsersMay 01, 2025 am 12:06 AMIntroduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting.
