Question

$.each(['a'], function(){$('<a/>').text(this).appendTo('body');});

=> firefox and chrome told me that ‘appendTo’ is not a function…

Answer 1

You can use:

$.each(['a'], function(idx, elem){$('<a/>').text(elem).appendTo('body');});

Or even better, just use a for loop:

var elements = ['a'];
for (var i in elements) {
    $('<a/>').text(elements[i]).appendTo('body');
}

It’s both easier to read and faster to execute.
