如何在jQuery中的选择器返回的值上创建折叠？

<div>First</div>
<div>Second</div>
<div>Third</div>

$(\'div\').text();

$(\'div\').text().foldl(\'\', function(){ ... join_or_whatever ... })

var result = $.makeArray($(\'div\')).reduce(function(prev,curr){ 
        return prev + \'\\n\' + $(curr).text() 
});

var newArray = [];
//\'div\' is an outer container of your inner divs
$(\'div\').each(function(index, Element) {
    newArray.push($(this).text());
});

$(\'body\').append(newArray.join(\'\'));

var finalStr = \"\";
$(\'div\').each(function(index) {
   finalStr += $(this).text() + \"<br>\";
});
