I'd be interested in seeing how using getElementsBySelector() performs (since on
some platforms it'll be using XPath which should be pretty fast). Also, someone
more CSS will probably correct my selector syntax.
link='mailto:';
var selector = 'input[type="checkbox" checked="true"]';
$A($('memberemail').getElementsBySelector(selector).each(function (el) {
link += el.value + ';';
}
