readme.md

Makes loading of multiple assets easier

Usage:

$.loadAssets({
	assets: {
		'asset1': 'foo.html',
		'asset2': { url: 'bar.json', type: 'jsonp' }
	},
	success: function(data) {
		// do something with data.asset1 and data.asset2
	}
});

ender.loadassets.coffee

Function::bind ?= (scope) ->
	_function = this
	() ->
		_function.apply scope, arguments

$.ender
	loadAssets: (opt) ->
		data = {}
		cnt = 0
		for id of opt.assets
			asset = opt.assets[id]
			if typeof(asset) == "string"
				opt.assets[id] = { url: asset, type: 'text' }
			cnt++
			context = 
				id: id
			loaded = (content) ->
				data[this.id] = content
				for id2 of opt.assets
					if not data[id2]? then return
				opt.success data
			$.ajax
				url: asset.url
				method: asset.method
				type: asset.type
				data: asset.data
				success: loaded.bind context
				error: (a) ->
					console.error a
		if cnt == 0 then opt.success data
