接着前面来。
去看了看去哪网和携程网的购票流程页面，还是去把12306的页面扒了一点，功能没有那么多，感觉够用算了。
今日任务：实现用户登录，根据出发站 和终点站 进行搜索车票 ，进行预定
下面是登陆前台代码：
$("#btn").click(function () { var a = new Object(); a.username = $("#userName").val(); a.userpwd = $("#password").val(); $.ajax({ url: "http://localhost:8989/myticket/car/user/login", type: "post", dataType: "json", contentType: ‘application/json;charset=UTF-8‘, data: JSON.stringify(a), success: function (data) { if (data.usertype == 1){ document.cookie = "cookie_userid = " + data.userid; document.cookie = "cookie_username = " + data.username; location.href="http://localhost:8989/myticket/static/html/12306/Index/index.html"; }else { alert("账号未激活，请前往激活后再登录"); } }, error: function () { alert("登录出错"); } }) })
后台代码：
<select id="userlogin" resultType="com.hp.entity.Userticket" parameterType="com.hp.entity.Userticket"> select *from userticket where username=#{username} and userpwd=#{userpwd}; </select>
登陆成功后进行查询 选票：
搜索后台代码：
<select id="getlist" resultType="com.hp.entity.Fresta"> select f.freid,f.frenumber,f.frebegintime,f.freendtime,f.freprice,f.frecarid, s1.stationname as stbegin,s2.stationname as stend from frequency f INNER join station s1 on f.frebeginsid=s1.stationid INNER join station s2 on f.freendsid=s2.stationid where f.frebeginsid in <foreach collection="a" index="index" open="(" separator="," close=")" item="a"> #{a} </foreach> and f.freendsid in <foreach collection="b" index="index" open="(" separator="," close=")" item="b"> #{b} </foreach> </select> <select id="getbyid" resultType="com.hp.entity.Fresta2"> select f.freid,f.frenumber,f.frebegintime,f.freendtime,f.freprice,f.frecarid, s1.stationname as stbegin,s2.stationname as stend from frequency f INNER join station s1 on f.frebeginsid=s1.stationid INNER join station s2 on f.freendsid=s2.stationid where f.freid=#{freid}; </select>
前台代码：
$.ajax({ url: "http://localhost:8989/myticket/user/city/getAllcity", type: "post", dataType: "json", success: function (data) { va.serch_result=data; },error:function () { alert("城市信息出错"); } })
$.ajax({
url:"http://localhost:8989/myticket/user/piao/fresta",
dataType:"json",
type:"post",
contentType:"application/json;charset=UTF-8",
data:JSON.stringify(a),
success:function (data) {
va.trainInfos = data;
},error:function (e) {
alert("查询失败");
}
})
遇到问题： vue 显示数据的时候出现错误， ajax 提交数据的时候如何 使用外键 ？
