A re-introduction to JavaScript (JS tutorial) - JavaScript
using the functions and objects that we've discussed previously, we could display the data like this: function makeperson(first, last) { return { first: first, last: last }; } function personfullname(person) { return person.first + ' ' + person.last; } function personfullname
reversed(person) { return person.last + ', ' + person.first; } var s = makeperson('simon', 'willison'); personfullname(s); // "simon willison" personfullname
reversed(s); // "willison, simon" this works, but it's pretty ugly.
...since functions are objects, this is easy: function makeperson(first, last) { return { first: first, last: last, fullname: function() { return this.first + ' ' + this.last; }, fullname
reversed: function() { return this.last + ', ' + this.first; } }; } var s = makeperson('simon', 'willison'); s.fullname(); // "simon willison" s.fullname
reversed(); // "willison, simon" note on the this keyword.
... we can take advantage of the this keyword to improve our makeperson function: function person(first, last) { this.first = first; this.last = last; this.fullname = function() { return this.first + ' ' + this.last; }; this.fullname
reversed = function() { return this.last + ', ' + this.first; }; } var s = new person('simon', 'willison'); we have introduced another keyword: new.

Adding Event Handlers to XBL-defined Elements - Archive of obsolete content
example, a custom checkbox might have a checked property which needs to be changed when the user clicks the checkbox: <handlers> <handler event="mouseup" action="this.checked=!this.checked"/> </handlers> when the user clicks and releases the mouse button over the check box, the mouseup event is sent to it, and the handler defined here is called, causing the state of the checked property to be
reversed.

<input>: The Input (Form Input) element - HTML: Hypertext Markup Language
for the input types whose domain of possible values is periodic (that is, at the highest possible value, the values wrap back around to the beginning rather than ending), it's possible for the values of the max and min properties to be
reversed, which indicates that the range of permitted values starts at min, wraps around to the lowest possible value, then continues on until max is reached.
Regular expressions - JavaScript
the roles of "class" and "argument" get
reversed: in the case of .match(), the string class (or data type) owns the method and the regular expression is just an argument, while in the case of .exec(), it is the regular expression that owns the method, with the string being the argument.
