使用正则表达式获取Google搜索的最后一个关键字

Question

I'm using a javascript regex to extract the keyword from a Google search. ( Extract keyword from Google search in Javascript )

The answer from the previous post works great except some cases when you do several searches in a row

ie I searched for the keyword "car" and I got some results, then I did another search for the keyword "plane" and I got the url ( http://www.google.com/search?q=car&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:fr:official&client=firefox-a#sclient=psy&hl=en&client=firefox-a&hs=P4M&rls=org.mozilla:fr%3Aofficial&source=hp&q=plane&aq=f&aq ... ). For this search I get the keyword "car" and then the keyword "plane" and what I'd like is only the last keyword ("plane").

Does someone know how to correct the regex from the previous to make it work ?

您提到的帖子中的JavaScript对我来说效果很好，并且仅返回“ plane”，请参见此处： http : //jsfiddle.net/EWx4S/
