1：创建html网页和js文件
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>xx信息查询</title>
</head> <body>
<div class="main pusher">
<form class="ui form vertical segment form-search">
<div class="fields">
<div class="sixCl wide field js_query_seq">
<label>订单号</label>
<input type="text" maxlength="50" name="orderNo" id="orderNo" placeholder="">
</div>
<!--https://blog.csdn.net/dreamweaver_zhou/article/details/79203297-->
<div class="sixCl wide field js_query_btype">
<label>排序字段</label>
<select name="sortFiled" id="sortFiled">
<option value="order_no">订单号</option>
</select>
</div> <div>
<label></label>
<input type="button" value="搜索" id="btSearch" class="ui right floated positive button btn-search"/>
</div> </div>
</form> <div class="table-container">
<table class="ui nine column table celled table-result" id="table-result">
<thead>
<tr>
<th>hotelSeq</th>
<th>酒店名称</th>
</tr>
</thead> <tbody id="tbody-result">
</tbody> </table>
</div>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.0.js"></script>
<script type="text/javascript" src="./js/cheatorder.js"></script>
<!--<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.3.min.js"></script>--> </div>
</body>
</html>
js
$(function() {
$('#btSearch').click(function () {
var orderNo = $('#orderNo').val();
var sortFiled = $('#sortFiled').val();
var tbody=window.document.getElementById("tbody-result");
$.ajax({
type: "post",
dataType: "json",
url: "/orderTest",
data: {
orderNo: orderNo,
sortFiled: sortFiled
},
success: function (msg) { //请求成功之后的操作
// if (msg.ret) {
var str = "";
// var data = msg.data;
var data1=msg[0];
// for (i in data) {
str += "<tr>" +
"<td>" + data1.hotelSeq + "</td>" +
"<td>" + data1.hotelName + "</td>" +
"</tr>";
// }
tbody.innerHTML = str;
// }
},
error: function () {
alert("查询失败")
}
});
});
});
2:开启服务，在chrome浏览器中浏览html网页
3：进入开发者模式
4：选择source ，在浏览器的js代码中打断点
5：点击触发js代码的按钮，进行调试。
6：调试页面
二：html代码中通过js提交表单数据
1.button的type设置为button 而不用submit，并添加onclick方法调用js函数 <input type="button" name="confirmAlter" value="确认修改" onclick="changeInfo(form1.code,form1.name,form1.detail,form1.count)"/> 2.传到js函数中，然后提交表单到servlet并传递参数 <script language="javascript">
function changeInfo(code,name,detail,count){
var string1 = code.value;
var string2 = name.value;
var string3 = detail.value;
var number = count.value;
//alert("hello word!"); document.getElementById('form1').action="workServlet?action=alterInfo&code="+string1+"&name="+string2+"&detail="+string3+"&count="+number;
document.getElementById("form1").submit();
}
</script> 3.在servlet中调用request.getParameter()方法即可获取参数
