UAM.js is a Universal Asset Manager, designed to be easy extendable for many asset types
Download and include the library in your application:
<script src="uam.min.js"></script>
Run Tests
Open test/test0/index.html in your browser and check out the example
First you need to create a configuration object. The object has two keys: in assetTypes you declare what needs to be done when the manager will load an asset, and assets key is an object containing pointers to assets (most commonly those will be URL strings, but can be anything, like arrays).
Here's an example of loading images:
var config = {
assetTypes: {
"image": function(url, asset){
var img = new Image();
img.onload = function(){
asset.data = img;
asset.done();
};
img.onerror = function(){ asset.error(); };
img.src = url;
}
},
assets: {
"image": [
"images/image1.png",
"images/image2.png"
]
}
};After that, we just load everything with an AssetManager:
var assetManager = new UAM.AssetManager(config);
assetManager.addEventListener("loaded", function(){
// use the loaded images
var myImage = assetManager.get('images/image1.png');
});
assetManager.load();Possible events are: loaded(), error(url) and progress(amountLeftToLoad, amountAllToLoad)
