這篇文章主要介紹了jQuery Jsonp跨域模擬搜索引擎的相關(guān)資料，非常不錯(cuò)，具有參考借鑒價(jià)值,需要的朋友可以參考下

效果還不錯(cuò) 就差加上鍵盤控制了...

代碼如下：

<!DOCTYPE html> 
<html> 
  <head> 
    <meta charset="utf-8" /> 
    <title>迷糊網(wǎng)羅</title> 
    <style type="text/css"> 
      * { 
        margin: 0; 
        padding: 0; 
      } 
      form { 
        position: absolute; 
        left: 50%; 
        top: 40%; 
      } 
      form input:nth-child(1) { 
        width: 450px; 
        height: 34px; 
        float: left; 
        font-size: 16px; 
        text-indent: 0.5em; 
        outline: none; 
        box-sizing: border-box; 
      } 
      form input:nth-child(1):focus { 
        border: 1px solid blueviolet; 
      } 
      form input:nth-child(2) { 
        height: 34px; 
        float: left; 
        background: blueviolet; 
        cursor: pointer; 
        width: 80px; 
        letter-spacing: 2px; 
        border: 0; 
        font-size: 14px; 
        line-height: 34px; 
      } 
      #oul { 
        position: absolute; 
        left: 0; 
        top: 34px; 
        background: white; 
        width: 530px; 
        box-shadow: 3px 3px 5px #F3F3F3; 
        border: 1px solid #F3F3F3; 
        box-sizing: border-box; 
        display: none;
