這個做了我想做的事,也是高手
$('section img').each(
function(){
var src = this.src,
h = $(this).height(),
w = $(this).width();
$(this).closest('div').css({
'min-width' : w,
'min-height' : h,
'background-image' : 'url(' + src + ')',
'background-repeat' : 'no-repeat',
'background-position' : '50% 50%'
});
}).remove();
=======
'background-image' : 'url(' + src + ')',
記得在加上"" =>
'background-image' : 'url("' + src + '")',
