前端页面如下
<p class="form-group">
{!! Form::label('phone','新手机号',['class' => 'col-md-2 control-label']) !!}
<p class="col-md-5">
{!! Form::text('phone',null,['class'=>'form-control']) !!}
</p>
<p class="col-md-4">
<p class="form-control-static">
<a href="#">发送验证码</a>
</p>
</p>
</p>
后台发送方法位sendVerifyMessage,对应的路由为domain/send-verify-message
求js代码能够将用户输入的手机号，验证，并传入后台的代码。

需要jquery 和 jquery.cookie
var SendCode = (function($, Cookies) {
