Minified.js Beta 4: Features and Changes

Beta 4 is a relatively small release. Notable changes include the new functions per() and onFocus(), a reorganization of request()'s advanced options as well as a new value for this in all event handlers.

Main reason to release it so early and with so few features is that I wanted to release some backward-incompatible changes as soon as possible. After beta 4 I intend to keep further backward-incompatible changes to a minimum, as Minified steers slowly towards its first stable release.

Backward-incompatible Changes

New: Iteration over sub-lists with per()

per() is an iteration function like each(), but with one key difference: it invokes the callback with the elements wrapped in a single-item Minified list. This can simplify your code in some cases.

$('.withHoverEffect').per(function(el) {
    el.onOver(el.toggle('hoverEffect'));
});

per() also supports sub-selects. That can make it easier to create events when you use iteration in templates:

$('#list').add(HTML('{{each}}<li>{{this.name}} <a class="del" href="#">Delete</a></li>{{each}}', items)
           .per('.del', function(el, index) {
               el.on('click', deleteItemByName, [items[index].name]);
           }));

New: onFocus() for toggling when an element gets focussed

per() is an iteration function like each(), but with one difference: it invokes the callback with the elements wrapped in a single-item Minified list. This can simplify your code in some cases.

$('input').per(function(el) {
    el.onFocus(el.toggle('isFocussed'));
});

New: reduce() for Minified lists

Beta 4 (re-)adds a simple reduce() version to the Util module.

var sum = _(1, 2, 3, 4, 5).reduce(function(memo, value, index) {
    return memo + value;
}, 0);

Change: on(), onOver() and onChange() return target wrapped in a list

Before beta 3, on() would call its handler with this set to the event source. Starting with beta 4, it passes a Minified list containing the event source as its only element.

onOver() and onChange() have also been modified accordingly.

Change: request() uses settings object, support for setting XHR properties

$.request()'s headers, username and password arguments have been moved into an object as 4th argument. You can now also set XMLHttpRequest properties.

Change: HTML() and ht() support templates stored in script tags

HTML() and ht() can now automatically get the template from a HTML <script> tag. This is mostly useful when you have large scripts that can not be conveniently stored in a JavaScript string, or when you need to store the string on the HTML page for internationalization purposes.

First create a <script> tag with a type not supported by the browser and put your template in there, like this: 

<script id="myTimeTpl" type="minified-template">The time is {{HH:mm:ss}}.</script>

Then you can specify the tag's id directly to access it:

$('#timeDisplay').ht('#myTimeTpl', new Date());

Site: Comments in API docs (Disqus)

Minified's API documentation supports comments now. It uses Disqus as its backend.
