HTML5每日一练之FileList文件列表对象的应用
在过去,上传文件的时候,我们每次都只能一次选择一个文件。如果想实现多文件上传,要么动态的增加file框要么使用Flash来代替。现在我们在HTML5中要想实现这个功能,是轻而易举的事情。
FileList对象:
FileList对象,其实就是多个file对象的列表。在HTML5中要想多文件上传我们只需要在原有的file类型的Input中加入multple属性即可。
HTML
JavaScript
为了能够让大家看清楚这个上传文本框,简单的写了一下JS,通过它来遍历出filelist中的文件,JS看不懂的话也没有关系,在这里主要是为了演示此控件的确获取了多个文件。
- function showFileName()
- {
- var file = document.getElementById("W3Cfuns_FileList");
- for(var i = 0, j = file.files.length; i
- {
- alert(file.files.name);
- }
- }
完整的代码
-
W3Cfuns_FileList - function showFileName()
- {
- var file = document.getElementById("W3Cfuns_FileList");
- for(var i = 0, j = file.files.length; i
- {
- alert(file.files.name);
- }
- }

Running the H5 project requires the following steps: installing necessary tools such as web server, Node.js, development tools, etc. Build a development environment, create project folders, initialize projects, and write code. Start the development server and run the command using the command line. Preview the project in your browser and enter the development server URL. Publish projects, optimize code, deploy projects, and set up web server configuration.

H5 page production refers to the creation of cross-platform compatible web pages using technologies such as HTML5, CSS3 and JavaScript. Its core lies in the browser's parsing code, rendering structure, style and interactive functions. Common technologies include animation effects, responsive design, and data interaction. To avoid errors, developers should be debugged; performance optimization and best practices include image format optimization, request reduction and code specifications, etc. to improve loading speed and code quality.

The steps to create an H5 click icon include: preparing a square source image in the image editing software. Add interactivity in the H5 editor and set the click event. Create a hotspot that covers the entire icon. Set the action of click events, such as jumping to the page or triggering animation. Export H5 documents as HTML, CSS, and JavaScript files. Deploy the exported files to a website or other platform.

H5 is not a standalone programming language, but a collection of HTML5, CSS3 and JavaScript for building modern web applications. 1. HTML5 defines the web page structure and content, and provides new tags and APIs. 2. CSS3 controls style and layout, and introduces new features such as animation. 3. JavaScript implements dynamic interaction and enhances functions through DOM operations and asynchronous requests.

Its advantages lie in cross-platformity and rich interactivity, but its limitations lie in complex interactions and animations, local resource access and offline capabilities.

H5 pop-up window creation steps: 1. Determine the triggering method (click, time, exit, scroll); 2. Design content (title, text, action button); 3. Set style (size, color, font, background); 4. Implement code (HTML, CSS, JavaScript); 5. Test and deployment.

Yes, H5 page production is an important implementation method for front-end development, involving core technologies such as HTML, CSS and JavaScript. Developers build dynamic and powerful H5 pages by cleverly combining these technologies, such as using the <canvas> tag to draw graphics or using JavaScript to control interaction behavior.
