I'm not a fan of appendTo, in a case like this to me it looks like
reading code backwards, rather than nicely nesting.
Ok, this does work:
var list = ['foo', 'bar', 'baz'];
var ul = $('#myul');
list.forEach(function(data) {
ul.append($('<li/>')).text(data);
});
The extra $() call isn't bad, it's short enough, I just don't want to do
a long "ul.append(document.createElement('li'))...." each and every time
I insert a single dom node.
As for using .each, I do know about that. However I'm not a fan of using
a jQuery method for iterating over data. I prefer sticking with the
native JavaScript 1.6/1.8 methods and tossing in compatibility for the
browsers without them.
Only reason I would possibly use jQuery to iterate over an array of
data, is if jQuery offered a method similar to my framework's .load
method. (actually it would be nice if jQuery also supported something
like my .nest)
pf('#foo').append('li').nest(function()
{
this.text('...');
this.append('img', {src:...}).click(function()
... do stuff ...
if(somecondition) this.addClass('foo');
});
pf('#myli').load([{name:'foo'}, {name:'bar', class: 'out'}, {name:'baz'}],
function(data) {
this.text(data.name);
if(class) this.addClass(class);
});
