---------------------------------------搜索建议使用方式---------------------------------------------

 以百度为例，API返回的是JSONP数据，JSONP是跨域访问的一种方式。由于服务器返回的JavaScript代码可以直接引用，通过回调函数的方式就可以间接的获取服务器的数据。

 下面是一个回调搜索建议的例子，window.baidu.sug 返回的是一个json对象

        <script type="text/javascript">
            window.onload = function() {
                
                //组装查询地址
                var sugurl = "http://suggestion.baidu.com/su?wd=#content#&cb=window.baidu.sug";
                var content = "关键字";
                sugurl = sugurl.replace("#content#", content);

                //定义回调函数
                window.baidu = {
                    sug: function(json) {
                        console.log(json)
                    }
                }

                //动态添加JS脚本
                var script = document.createElement("script");
                script.src = sugurl;
                document.getElementsByTagName("head")[0].appendChild(script);

            }
        </script>

控制台打印的结果：如果要将结果保存在一个字符串数组中，只需要 var arr = json.s 即可。
