thinkphp5使用bootstrapvalidator进行异步验证邮箱的示例

/** * Created by HONGXIN on 2017-10-23. */$(function () {  $('form').bootstrapValidator({    message: 'This value is not valid',    feedbackIcons: {      valid: 'glyphicon glyphicon-ok',      invalid: 'glyphicon glyphicon-remove',      validating: 'glyphicon glyphicon-refresh'    },    live: 'disabled',//验证失败后，提交按钮仍然是可选状态    fields: {      email: {        message: '用户名验证失败',//默认        verbose: false,        validators: {          notEmpty: {            message: '邮箱不能为空'          },          emailAddress: {            message: '邮箱地址格式有误'          },          remote: {            url: '/ajax_email',            message:"此邮箱已经注册",            type: "post",            dataType: 'json',            data: {              //默认传递的就是输入框的值            },            delay: 500,//延迟效果          },        }      },      password: {        validators: {          notEmpty: {            message: '邮箱地址不能为空'          },          stringLength: {            min: 6,            max: 18,            message: '用户名长度必须在6到18位之间'          },        },      },      password2: {        validators: {          notEmpty: {            message: '确认密码不能为空'          },          identical: {            field: 'password',            message: '两次密码必须一致'          }        }      },      username:{        validators: {          notEmpty: {            message: '用户名不能为空'          },          stringLength: {            min: 2,            max: 8,            message: '用户名长度必须在2到8位之间'          }        }      }    }  });});

  public function ajax_email(){    //该message可以为空，它替换JS验证的message属性    echo json_encode(['valid'=>false,'message'=>'验证码不正确']);  }
