求大神幫忙修改下列js代碼，要實作的功能是：
選擇串列中的li1要實作
http://search.chinalaw.gov.cn/SearchLawTitle?effectLevel=&SiteID=124&Query="輸入的關鍵詞"
的搜索
選擇串列中的li2要實作
http://std.samr.gov.cn/search/std?q="輸入的關鍵詞"
的搜索
選擇串列中的li3要實作
http://www.sxpc.gov.cn/sxsrdsearch/search.jsp?sword="輸入的關鍵詞"
的搜索
現在第一個搜索可以做到，怎么實作第二、第三個搜索。

按你自己說的，你這都做好了第一個。后面兩個不就是換一下那個網址嗎？三個網址存一個陣列中，先獲取當前是哪種搜索(li索引)。然后從陣列中取出對應的網址，拼好你的關鍵詞。window.open()
