下面我就為大家分享一篇淺談ajax在jquery中的請求和servlet中的回應，具有很好的參考價值，希望對大家有所幫助。
在jsp中，首先，你需要匯入jquery的架包：
# 取得可傳回網站的根路徑：
<% String path = request.getContextPath(); %>
在jquery中寫ajax請求：
#
<script type="text/javascript">
$(function(){
$(".B").click(function(){
$.ajax({
type: "GET",
//对应servlet中的方法
url: "<%=path%>" + "/queryEvaluateByuserId.do",
//返回是json数据
dataType: "json",
async:false,
data:{
},
success: function(data){
str = "";
if(data != null){
//循环表单列表
for (var i in data)
{
var num = parseInt(i) + 1 ;
str +="<tr><td>" + num + "</td><td>"
+ data[i]['name'] + "</td><td>"
+ data[i]['price'] + "元</td>"
+ "</tr>";
}
$(".trtd4").after(str);
}else{
}
},
error: function(data){
}
})
});
}
</script>##jsp部分：#
<p class="tab-pane" id="B" style="text-align:center;">
<p class="row marg" >
<table border="2 " style="width:80%;text-align:center;">
<tr class="trtd4">
<th>序号</th>
<th>业主名</th>
<th>金额</th>
</tr>
</table>
</p>
</p>在servlet中用到了阿里巴巴的快速轉換json的套件com.alibaba.fastjson.JSON：
private void queryEvaluateByuserId(HttpServletRequest request, HttpServletResponse response) throws SQLException, IOException, ServletException{
HttpSession session=request.getSession();
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
Cookie[] cookies = request.getCookies();
int ownerId = 0;
for (int i = 0; i < cookies.length; i++) {
Cookie cookie = cookies[i];
if (cookie.getName().equals("ownerId")) {
ownerId = Integer.parseInt(cookie.getValue());
}
}
List<Order> orderList = new ArrayList<>();
List<Evaluate> queryEvaluateList = new ArrayList<>();
orderList = orderServiceImpl.queryOrderList(ownerId, null, null, null, null, null);
List<Map<String, String>> workers = new ArrayList<Map<String, String>>();
for(int i = 0;i < orderList.size();i++){
Map<String,String> order = new HashMap<String, String>();
order.put("description", orderList.get(i).getDescription());
order.put("name", orderList.get(i).getOwnerName());
System.out.println(orderList.get(i).getDescription());
order.put("type",orderList.get(i).getTypeName());
queryEvaluateList = orderServiceImpl.queryEvaluateListByUserId(orderList.get(i).getId());
order.put("comment", queryEvaluateList.get(0).getComment());
List<Allocation> allocation = orderServiceImpl.queryAllocationByOrderId(orderList.get(i).getId());
order.put("price", String.valueOf(allocation.get(0).getPrice()));
System.out.println(order);
workers.add(order);
}
//将map键值对转换成json，传给jsp
response.getOutputStream().write(JSON.toJSONBytes(workers));
}以上是有關ajax在jquery中的請求（詳細教程）的詳細內容。更多資訊請關注PHP中文網其他相關文章！
