1、頁面程式碼如下

<div class="d-search-condition">
<label class="d-search-condition-label">病人姓名：</label>
<input type="text" id="zybrxm" name="zybrxm" maxlength="20" value="${zybrxm }" oninput="change()" required="required"  class="inputbox-text inputbox-text-border" >
<label class="input-required" >*</label>
</div>
<!-- 模糊查詢匹配 -->
<div id='brxmDiv' class="d-search-autodiv" onmouseleave="hide()" style="display:none;">  
<select id='brxmSelect' size="3" onclick="checked()" style='margin-top:0px;' class="d-search-autoselect">
</select>

</div>

樣式部分如下：

.inputbox-text{folat:left; display:block;font-size:12px;line-height:28px;height:28px;width:70%;padding:0;border:0 solid #ccc;border-right:0 solid #ccc;overflow:hidden;padding-left:3px;margin:0 auto;color:#444;box-sizing:border-box;padding:0 5px;}
.inputbox-text-border{border:1px solid #dadada !important;}
.inputbox-text {display: inline-block;}
.d-search-container-2x .d-search-condition,.d-search-container-2x .d-search-condition-btn{padding: 0 0 0 190px;box-sizing: border-box;}
.inputbox-text-readonly{
background:#DDDDDD;
} 
.d-search-condition-label{
display: inline-block;
font-size: 12px;
text-align: right;
width:60px;
folat:left; 
}
/* 必填項提示，紅色* */
.input-required{}
.d-search-autodiv{folat:left; display:block;font-size:12px;line-height:28px;position:fixed
padding:0;border:0 solid #ccc;border-right:0 solid #ccc;
background:#fff;overflow:hidden;padding-left:3px;margin-left:120px;
color:#444;box-sizing:border-box;padding:0 5px;}
.d-search-autoselect{folat:left; display:block;font-size:12px;line-height:28px;
padding:0;border:0 solid #ccc;border-right:0 solid #ccc;
background:#fff;overflow:hidden;padding-left:3px;margin-left:120px;
color:#444;box-sizing:border-box;padding:0 5px;}

2、js程式碼

//模糊查詢
function change() {
var content="";

var  sc= $("#zybrxm").val();

//清空之前的模糊匹配資訊
document.getElementById("brxmSelect").options.length=0;

//顯示div  設定顯示的高度
$("#brxmDiv").css("display","block");
var zybrxmWidth = $('#zybrxm').width();
$("#brxmSelect").css("width",zybrxmWidth);

//ajax 開始
$.ajax({
type: "POST",
dataType: "JSON",
url: '${pageContext.request.contextPath }/q0103/select.act',  

//引數
data: {sc:sc},
success: function(data){

//遍歷返回的JsonArray
$.each(data,function(index,data){
content += "<option value="+data['bh']+"> "+"["+data['bh']+"]"+data['mc']+"</option>";
});

//動態將option 寫入select
document.getElementById("brxmSelect").innerHTML=content;
 }
}
);
}
//模糊查詢select選中事件 可以賦值或是進行其他操作
function checked()
{
var myselect=document.getElementById("brxmSelect");
var index=myselect.selectedIndex ;
$("#zybrbh").val(myselect.options[index].value);
$("#zybrxm").val(myselect.options[index].text.split("]")[1]);
}
//滑鼠滑出模糊查詢div，隱藏div事件
function hide()
{
$("#brxmDiv").css("display","none");
}

3、controller層程式碼

//模糊匹配
@ResponseBody
@RequestMapping("/select")
public String select(HttpServletResponse response, ModelMap modelMap,
HttpServletRequest request, HttpSession session, Model opusmodel)
throws Exception {
String name = request.getParameter("sc");
List<Map<String,Object>> list = dao.selectByName(name);
String ret = JSONArray.fromObject(list).toString();

//返回jsonArray資料
return ret;
}

4、dao層

public List<Map<String, Object>> selectByName(String name) throws Exception{
StringBuffer sql=new StringBuffer();
sql.append(" select top 10  bh, mc from table ");
sql.append(" where mc like '%"+name+"%'");
return this.queryForList(sql.toString());
}
