Modernizr tests which native CSS3 and HTML5 features are available in the current UA and makes the results available to you in two ways: as properties on a global Modernizr object, and as classes on the <html> element. This information allows you to progressively enhance your pages with a granular level of control over the experience.
Often times people want to know when an asynchronous test is done so they can allow their application to react to it.
In the past, you've had to rely on watching properties or <html> classes. Only events on asynchronous tests are
supported. Synchronous tests should be handled synchronously to improve speed and to maintain consistency.
The new API looks like this:
// Listen to a test, give it a callback
Modernizr.on('testname', function( result ) {
if (result) {
console.log('The test passed!');
}
else {
console.log('The test failed!');
}
});We guarantee that we'll only invoke your function once (per time that you call on). We are currently not exposing
a method for exposing the trigger functionality. Instead, if you'd like to have control over async tests, use the
src/addTest feature, and any test that you set will automatically expose and trigger the on functionality.
- Clone or download the repository
- Install project dependencies with
npm install
Run the test suite
npm install
./bin/modernizr -c lib/config-all.json
//outputs to ./modernizr.jsgrunt testgrunt build
serve .
visit <url>/testserve the root dir, <url>/test/modular.html
- checkout the modernizr.com code
- install all your gems and bundles and jekyll and shit
jekyllserve ./_sites- visit /download
- It should be just a big list of things you can build with no frills.
Modernizr can be used programmatically via npm:
var modernizr = require("modernizr");A build method is exposed for generating custom Modernizr builds. Example:
var modernizr = require("modernizr");
modernizr.build({}, function (result) {
console.log(result); // the build
});The first parameter takes a JSON object of options and feature-detects to include. See lib/config-all.json for all available options.
The second parameter is a function invoked on task completion.
