OT Adam D Ruppe's web stuff

[Adam D. Ruppe]

Here's more ddocs.

http://arsdnet.net/web.d/dom.html


Not terribly useful, I'll admit. The Javascript
discussion at the bottom of the first link might be
good to read though.

The dom.html there is mostly just (incomplete) method
listing. I didn't write most of it up at all.

When I started doing dom.d, I was going to be strictly
a clone of the browser implementation, so some of the
comments still say things like "extension", but I went
my own direction a long time ago.

I don't know... I think most of the dom is self-explanatory
if you're already experienced with javascript anyway though.


BTW here's something I wrote up on aother site as an
example of how awesome D is:




examples:
[code="D ROX"]

// don't need a document to create elements
auto div = Element.make("div", "Hello <there>"); // convenience 
params do innerText
assert(div.innerText == "Hello <there>"); // text set
assert(div.innerHTML == "Hello <there>"); // html properly 
encoded mindlessly

// getting and setting attributes works w/ property syntax
// of course they are always properly encoded for charset and 
html stuffs
div.id = "whoa";
assert(div.id == "whoa");
div.customAtrribute = div.id ~ "works";
assert(div.customAttribute == "whoaworks");

// i also support the dataset sugar over attributes

div.dataset.myData = "cool";
assert(div.getAttribute("data-my-data") == "cool" == 
div.dataset.myData);

// as well as with the style..

div.style = "top: 10px;" // works with strings just like any 
other attribute

div.style.top = "15px"; // or with property syntax like in 
javascript

assert(div.style.top == "15px"); // reading works no matter how 
you set it
assert(div.style == "top: 15px;"); // or you can read it as a 
string


// i have convenience methods too

div.innerText = "sweet"; // worx, w/ proper encoding

// calls Element.make and appendChild in one go.
// can easily set text and/or a tag specific attribute
auto a = div.addChild("a", "Click me!", "link.html"); // tagName, 
value, value2, dependent on tag

a.addClass("cool").addClass("beans"); // convenience methods 
(chainable btw) for the class attribute
assert(a.hasClass("cool") && a.hasClass("beans") && 
!a.hasClass("coolbeans"));
assert(a.className == "cool beans");

// subclasses rock too, especially with automatic checked casts
Link link = div.requireSelector!Link("a"); // css selector syntax 
supported
// alternatively:
link = cast(Link) a; // but if a isn't actually a Link, this can 
be null

// easy working with the link url
a.setValue("cool", "param");
assert(a.href == "link.html?cool=param");

// arsd.html also includes functions to convert links into POST 
forms btw

// the Form subclass rox too

auto form = cast(Form) Element.make("form");
form.method = "POST";
// convenience functions from the browsers are here but who needs 
them when the dom rox?
form.innerHTML = "<select 
name=\"cool\"><option>Whoa</option><option>WTF</option></select>";

// similarly to the Link class, you can set values with ease
form.setValue("cool", "WTF"); // even works on non-text form 
elements
form.setValue("sweet", "whoa"); // also can implicitly create a 
hidden element to carry a value (can lead to mistakes but so 
useful)


// and the Table class is pretty sweet

auto table = cast(Table) Element.make("table");
table.caption = "Cool"; // sets the caption element, not an 
attribute

// variadic templates rok
table.appendRow("sweet", "whoa", 10, Element.make("a")); // adds 
to the <tbody> a <tr> with appropriate children
[/code]


some people luv jquery and think it is the best thing ever

those people have never used my dom library


Speaking of jquery, what about collections of elements?

Well D has this thing called foreach which does that. But, just
to prove I could, I wrote a couple dozen lines of D to do this:

==
document["p a"].addClass("mutated").appendText("all links in 
paragraphs get this text and that class!");
==



Operator overloading template craziness!

But i'm pretty meh on that since foreach is better anyway.
