|
||
* @param {function|boolean} test - Function returning true if feature is supported,
|
||
* false if not. Otherwise a boolean representing the results of a feature detection
|
||
* @example
|
||
*
|
||
* The most common way of creating your own feature detects is by calling
|
||
* `Modernizr.addTest` with a string (preferably just lowercase, without any
|
||
* punctuation), and a function you want executed that will return a boolean result
|
||
*
|
||
* ```js
|
||
* Modernizr.addTest('itsTuesday', function() {
|
||
* var d = new Date();
|
||
* return d.getDay() === 2;
|
||
* });
|
||
* ```
|
||
*
|
||
* When the above is run, it will set Modernizr.itstuesday to `true` when it is tuesday,
|
||
* and to `false` every other day of the week. One thing to notice is that the names of
|
||
* feature detect functions are always lowercased when added to the Modernizr object. That
|
||
* means that `Modernizr.itsTuesday` will not exist, but `Modernizr.itstuesday` will.
|
||
*
|
||
*
|
||
* Since we only look at the returned value from any feature detection function,
|
||
* you do not need to actually use a function. For simple detections, just passing
|
||
* in a statement that will return a boolean value works just fine.
|
||
*
|
||
* ```js
|
||
* Modernizr.addTest('hasJquery', 'jQuery' in window);
|
||
* ```
|
||
*
|
||
* Just like before, when the above runs `Modernizr.hasjquery` will be true if
|
||
* jQuery has been included on the page. Not using a function saves a small amount
|
||
* of overhead for the browser, as well as making your code much more readable.
|
||
*
|
||
* Finally, you also have the ability to pass in an object of feature names and
|
||
* their tests. This is handy if you want to add multiple detections in one go.
|
||
* The keys should always be a string, and the value can be either a boolean or
|
||
* function that returns a boolean.
|
||
*
|
||
* ```js
|
||
* var detects = {
|
||
* 'hasjquery': 'jQuery' in window,
|
||
* 'itstuesday': function() {
|
||
* var d = new Date();
|
||
* return d.getDay() === 2;
|
||
* }
|
||
* }
|
||
*
|
||
* Modernizr.addTest(detects);
|
||
* ```
|
||
*
|
||
* There is really no difference between the first methods and this one, it is
|
||
* just a convenience to let you write more readable code.

|

|

|
||
* @example
|

* `Modernizr.testStyles` takes a CSS rule and injects it onto the current page
|
||
* along with (possibly multiple) DOM elements. This lets you check for features
|
||
* that can not be detected by simply checking the [IDL](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Interface_development_guide/IDL_interface_rules).
|

* ```js
|
||
* Modernizr.testStyles('#modernizr { width: 9px; color: papayawhip; }', function(elem, rule) {
|
||
* // elem is the first DOM node in the page (by default #modernizr)
|
||
* // rule is the first argument you supplied - the CSS rule in string form
|
||
*
|
||
* addTest('widthworks', elem.style.width === '9px')
|
||
* });
|
||
* ```
|
||
*
|
||
* If your test requires multiple nodes, you can include a third argument
|
||
* indicating how many additional div elements to include on the page. The
|
||
* additional nodes are injected as children of the `elem` that is returned as
|
||
* the first argument to the callback.
|
||
*
|
||
* ```js
|
||
* Modernizr.testStyles('#modernizr {width: 1px}; #modernizr2 {width: 2px}', function(elem) {
|
||
* document.getElementById('modernizr').style.width === '1px'; // true
|
||
* document.getElementById('modernizr2').style.width === '2px'; // true
|
||
* elem.firstChild === document.getElementById('modernizr2'); // true
|
||
* }, 1);
|
||
* ```
|
||
*
|
||
* By default, all of the additional elements have an ID of `modernizr[n]`, where
|
||
* `n` is its index (e.g. the first additional, second overall is `#modernizr2`,
|
||
* the second additional is `#modernizr3`, etc.).
|
||
* If you want to have more meaningful IDs for your function, you can provide
|
||
* them as the fourth argument, as an array of strings
|
||
*
|
||
* ```js
|
||
* Modernizr.testStyles('#foo {width: 10px}; #bar {height: 20px}', function(elem) {
|
||
* elem.firstChild === document.getElementById('foo'); // true
|
||
* elem.lastChild === document.getElementById('bar'); // true
|
||
* }, 2, ['foo', 'bar']);

|
||
* version of the property, or `false` when it is unsupported.
|
||
* @example
|
||
*
|
||
* Modernizr.prefixed takes a string css value in the DOM style camelCase (as
|
||
* opposed to the css style kebab-case) form and returns the (possibly prefixed)
|
||
* version of that property that the browser actually supports.
|
||
*
|
||
* For example, in older Firefox...
|
||
* ```js
|
||
* prefixed('boxSizing')
|
||
* ```
|
||
* returns 'MozBoxSizing'
|
||
*
|
||
* In newer Firefox, as well as any other browser that support the unprefixed
|
||
* version would simply return `boxSizing`. Any browser that does not support
|
||
* the property at all, it will return `false`.
|
||
*
|
||
* By default, prefixed is checked against a DOM element. If you want to check
|
||
* for a property on another object, just pass it as a second argument
|
||
*
|
||
* ```js
|
||
* var rAF = prefixed('requestAnimationFrame', window);
|
||
*
|
||
* raf(function() {
|
||
* renderFunction();
|
||
* })
|
||
* ```
|
||
*
|
||
* Note that this will return _the actual function_ - not the name of the function.
|
||
* If you need the actual name of the property, pass in `false` as a third argument
|
||
*
|
||
* ```js
|
||
* var rAFProp = prefixed('requestAnimationFrame', window, false);
|
||
*
|
||
* rafProp === 'WebkitRequestAnimationFrame' // in older webkit
|
||
* ```
|
||
*
|
||
* One common use case for prefixed is if you're trying to determine which transition
|
||
* end event to bind to, you might do something like...
|
||
* ```js
|
||
* var transEndEventNames = {
|
||
* 'WebkitTransition' : 'webkitTransitionEnd', * Saf 6, Android Browser
|
||
* 'MozTransition' : 'transitionend', * only for FF < 15
|
||
* 'transition' : 'transitionend' * IE10, Opera, Chrome, FF 15+, Saf 7+
|
||
* };
|
||
*
|
||
* var transEndEventName = transEndEventNames[ Modernizr.prefixed('transition') ];
|
||
* ```
|
||
*
|
||
* If you want a similar lookup, but in kebab-case, you can use [prefixedCSS](#modernizr-prefixedcss).

This featured in both the 'tweener' syntax (implemented by IE10) and the 'modern' syntax (implemented by others). This detect will return `true` for either of these implementations, as long as the `flex-wrap` property is supported. So to ensure the modern syntax is supported, use together with `Modernizr.flexbox`:
