A re-introduction to JavaScript (JS tutorial) - JavaScript
t name fields. there are two ways in which the name might be displayed: as "first last" or as "last, first". 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 personfullnamereversed(person) { return person.last + ', ' + person.first; } var s = makeperson('simon', 'willison'); personfullname(s); // "simon willison" personfullnamereversed(s); // "willison, simon" this works, but it's pretty ugly. you end up with dozens of functions in your global namespace. what we really need is a way to attach a function to an object. since functions are objects, this is easy: function...
...s); // "willison, simon" this works, but it's pretty ugly. you end up with dozens of functions in your global namespace. what we really need is a way to attach a function to an object. since functions are objects, this is easy: function makeperson(first, last) { return { first: first, last: last, fullname: function() { return this.first + ' ' + this.last; }, fullnamereversed: function() { return this.last + ', ' + this.first; } }; } var s = makeperson('simon', 'willison'); s.fullname(); // "simon willison" s.fullnamereversed(); // "willison, simon" note on the this keyword. used inside a function, this refers to the current object. what that actually means is specified by the way in which you called that function. if you called it using dot notation or...
...e, without using s.fullname(), this is bound to the global object. since there are no global variables called first or last we get undefined for each one. 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.fullnamereversed = function() { return this.last + ', ' + this.first; }; } var s = new person('simon', 'willison'); we have introduced another keyword: new. new is strongly related to this. it creates a brand new empty object, and then calls the function specified, with this set to that new object. notice though that the function specified with this does not return a value but merely modifies the this obj...

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. similarly, you may wish to change a property when the element is focused. you might have a need to change whether an element can have the focus or not. for this, you can use a special style property -moz-user-focus. this property controls whether an element can be focused. (see focus and selection) handling mouse events for mouse events, you can use the button attribute to have the handler only ...
