一百二十：CMS系统之注册功能前后端逻辑

 

给提交按钮加一个id，方便写js

js

//发送ajax请求注册请求
$(function () {
   $('#submit-btn').click(function (event) {
       event.preventDefault();
       var telephone_input = $('input[name="telephone"]');
       var sms_captcha_input = $('input[name="sms_captcha"]');
       var username_input = $('input[name="username"]');
       var password1_input = $('input[name="password1"]');
       var password2_input = $('input[name="password2"]');
       var graph_captcha_input = $('input[name="graph_captcha"]');

       var telephone = telephone_input.val();
       var sms_captcha = sms_captcha_input.val();
       var username = username_input.val();
       var password1 = password1_input.val();
       var password2 = password2_input.val();
       var graph_captcha = graph_captcha_input.val();

       ajax.post({
           'url': '/signup/',
           'data': {
               'telephone': telephone,
               'sms_captcha': sms_captcha,
               'username': username,
               'password1': password1,
               'password2': password2,
               'graph_captcha': graph_captcha
           },
           'success': function (data) {
                if(data['code'] == 200){
                    window.location = '/';  // 登录成功后跳转到首页
                }else{
                    xtalert.alertInfo(data['message']);
                }
           },
           'fail': function () {
               xtalert.alertNetworkError();
           }
