通过Ajax操作Dom：

if(xmlHttp.readyState == 4){
            if(xmlHttp.status == 200){
                var sobj = document.getElementById("suggest");
                var str = xmlHttp.responseText.split("-");
                var suggest = "";
                if(str.length >0 && str[0].length > 0){
                    for(var i=0; i<str.length; i++){
                        suggest += "<div class='suggest_link' " +
                                " onmouseover="this.className='suggest_link_over'" " +
                                " onmouseout="this.className='suggest_link'" >"+str[i]+"</div>"
                    }
                    sobj.innerHTML = suggest;
                    sobj.style.display = "block";
                }else{
                    sobj.style.display = "none";
                }
            }
        }

把数据库中的数据显示在界面上。
