第一步：根据学号和绑定的邮箱来进行密码的找回
第二步：输入想要设定的新密码，并输入邮箱收到的验证码
wxml代码如下：
!--pages/forgotpwd/forgotpwd.wxml--!-- textpages/forgotpwd/forgotpwd.wxml/text --view class='content' form bindsubmit='submit_email' wx:if="{{form_index ==0}}" label找回密码：第一步/label view class="sections" input name="no" type='number' placeholder-class='small' placeholder='请输入学号' / /view view class="sections" input name="email" placeholder-class='small' placeholder='请输入绑定的邮箱' / /view button type='primary' placeholder-class='small' formType="submit" 下一步/button /form form bindsubmit='submit_password' wx:else label找回密码：第二步/label view class="section" view class="left" input name="pwd" password="{{mask}}" placeholder-class='small' placeholder='输入新密码' / /view view class="right" switch bindchange="switchChange"/ /view /view view class="section" view class="left" input name="validcode" type='number' placeholder-class='small' placeholder='输入邮件中的验证码'/ /view view class="right" text style="color:#aaa"剩余：{{second}}秒/text /view /view button type='primary' placeholder-class='small' formType="submit" disabled="{{disabled}}"提交/button /form/view调用的js代码
