jquery 取字符串中数字的正则

核心代码:
代码如下:
var paddleft = $(".teacher-title").css("padding-left").replace(/[^0-9]/ig, "");
var num=parseInt(paddleft);

演示代码:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>jquery获取页面样式中的值</title> <style type="text/css"> .teacher-title{padding-left:50px; width:200px;} </style> <script type="text/javascript" src="jquery.js"></script> </head> <body> 看看那 <script> var paddleft = $(".teacher-title").css("padding-left").replace(/[^0-9]/ig, ""); var num=parseInt(paddleft); alert(num); </script> </body> </html>
