Javascript 选择高度大于给定值的所有图元

如何选择高度大于200px的项目，并在变量中记住它们

var something = $('.myClass').withHeightMoreThan200px();
$('.myClass').each(function(){$(this).height(random(50,500)});
something.hide(); //even if after random change of height some new elements have now height >200px I want it to affect only those remembered before.

使用：

var something = $('.myClass').filter(function(){
    return $(this).height() > 200;
});
