调用百度“搜索建议（BaiduSuggestion）”的 API
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
原理
當(dāng)前發(fā)送一個(gè) Get 請(qǐng)求：http://suggestion.baidu.com/su?wd=wq&p=3&cb=window.bdsug.sug&t=1324271669786
注意 wd：搜索關(guān)鍵字
cb：callback 回調(diào)函數(shù)
那么百度將返回一個(gè)如下的 json 數(shù)據(jù)：
window.bdsug.sug({q:"wq",p:true,s:["wqvga","wqi","wqsg_umd","wqynyl","wqi下載","wqrc","wqnmlgb","wqvga分辨率","吳奇隆","吾棲之膚"]});
?
其實(shí)最復(fù)雜的是如何在客戶端展示這些數(shù)據(jù)，需要用到 css 和 js。
正好園子里有朋友做了，感謝！
