A JavaScript Preloader with Download Status and Priorities

Posted · Category: MIT License, Upload

PxLoader is a Javascript library that helps you download images, sound files or anything else you need before you take a specific action on your site (like showing a user interface or starting a game). You can use it to create a preloader for HTML5 games (e.g. Cut the Rope) and websites.

It let’s you monitor download status by providing progress and completed events and it lets you prioritize the order in which items are downloaded. You can even tag groups of files and then prioritize downloads or register for events by tag.

Tutorial: HTML5 File Upload with Progress Bar

Posted · Category: MIT License, Upload

Html5 finally solves an age old problem of being able to upload files while also showing the upload progress. Essentially, what you need to do is hook into the server’s byte stream while it is receiving a file so you know how many bytes you’ve received and somehow convey that information back to the client browser, while it is still in the process of uploading the file.

Matlus has written a really throughout tutorial on how to make a HTML5 File Upload with Progress, which is uploading of files using XMLHttpRequest and providing upload progress information to the end-user. This solution does not require any change to the server side, at least insofar as handling the multipart/form-data protocol. So existing server side logic should remain unchanged, which makes adapting this technology that much easier.

Create Spinning Progress Indicator with Spin.js

Posted · Category: MIT License, Upload

Spin.js uses the CSS3 to render the UI, falling back to VML Internet Explorer. If supported by the browser, @keyframe rules are used to animate the spinner. The spin() method creates the necessary HTML elements and starts the animation. If a target element is passed as argument, the spinner is added as first child and horizontally and vertically centered.

There is no images and external CSS for Spin.js. It is highly configurable, and works in all major browsers, including IE6. It is smaller than an animated GIF (2.8K minified, 1.7K gzipped).
