Alpha 4 released!

It’s been a long three months but we’re very happy to announce the release of jQuery Geo 1.0a4! Here are some highlights and details:

At the service level

In alpha 3, you could append and interact with shapes on the map. In alpha 4, this is extended to services! Service-level shapes have their own shapeStyle apart from the map’s and hide when their service is hidden.

More modes!

There are new modes to let you measure distance & area, and a static mode for when you want to display a map but not let users interact with it. Apart from the three new built-in modes, you can also create custom modes to help organize your app.

What’s that? CSS labels!

You can now give any shape a label when you append it. You can style the label from your regular style sheet using the .geo-label class which opens labeling up to all the design power of CSS3. There’s even more potential if you put a class or id on your map service because you can target labels on different services using CSS rules. Also, labels can be any HTML which opens them up to new features in HTML5!

More service src options

The old getUrl property has been renamed to src (see Breaking below) and you can now set it to a string template. jQuery Geo will stick your tile row, column, zoom, or image bbox in for you. Services defined as a string are a little easier on the eyes than a function and can be stored as JSON data.

You can still use a function and the function can now return a jQuery Promise to delay loading of the map image or tile. Want to calculate a Mandlebrot image in a JavaScript web worker without blocking user interaction? Return a new jQuery.Deferred() and call resolve when you’re done!

Mobile

This version has better mobile support including pinch zoom on iOS and Android 3+ as well as other bug fixes for mobile devices.

Don’t worry about $.geo.proj so much

You can now send either geodetic (lon, lat) or projected (x, y) coordinates to any library function and it will return accordingly if you stay on the default web mercator projection. You should still set it to null or implement the (to|from)GeodeticPos functions if you need to change projections.

Breaking

There is one deprecation (a service object property will be renamed in beta) and one minor breaking change.

To align this API with HTML itself, the getUrl property on service objects will be renamed to src. Using either src or getUrl will work for this alpha release but getUrl will be removed for beta. Please update any map services to use the new src property when you’re defining them.

Also on service objects, the initial opacity and visibility are in a property of the service object itself named style. Your old services will still function but ones you may expect to be hidden initially will be visible until you update the service object.

To exemplify both of these changes, instead of:

{ type: "tiled", getUrl: function( view ) { return ""; }, visibility: "hidden" }

you should write:

{ type: "tiled", src: function( view ) { return ""; }, style: { visibility: "hidden" } }

Everything else

With over 60 commits, there are more features and bug fixes to write about. If you dare to click the link below (or read the README file on the project’s GitHub page) you can get a better idea of what went into this build. This is the last alpha release (!) and the path to beta will add unit testing, a better build process, and smaller, more refined source code. Thanks for all your support!
