怎样获取一个display：none的元素的宽高？补充问题【按照以下代码测试】<!DOCTYPE HTML><html><head> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> <meta charset="utf-8" /> <style type="text/css"> .m1 { display: none; width: 500px; height: 500px; margin: 0px auto; border: 1px solid red; } .m2 { width: 50%; height: 5%; border: 1px solid red; } </style> <!-- 这里可以自行引用jQuery --> <script type="text/javascript" src="js/jquery-1.8.3/jquery.min.js"></script></head><body> <div id="m1" class="m1"> <div id="m2" class="m2"></div> </div> <script type="text/javascript"> console.log($('#m2').height()); </script></body></html>
