Javascript 正则表达式 : Best Buy product ID from URL

Question

给定百思买 URL:

http://www.bestbuy.com/site/Microsoft+-+Xbox+360+4GB+Console+-+Black/1162184.p?id=1218228678498&skuId=1162184

如何使用 Javascript 获取 13 位产品 ID:

1218228678498

Answer 1

这似乎有效:

var url = "http://www.bestbuy.com/site/Microsoft+-+Xbox+360+4GB+Console+-+Black/1162184.p?id=1218228678498&skuId=1162184";

//look for fist question mark in the url, then for id property as a first capture group
var regx = /\?.*?id=(.*?)&/g;

//get first group match
var id = regx.exec(url)[1]);

此正则表达式将从任何 URL 获取任何 id HTTP 查询参数。
