这里主要是用到了$watch监察数据的变化，并用正则判断数据是否符合要求。

关键HTML代码：

<div class="row row-form">      <div class="col col-form">        <div class="list">          <div class="row row-code">            <div class="col col-60 col-mobile">              <label class="item item-input mobile-btn">                <input type="text" placeholder="手机号" name="mobile_num" id="mobile_num" ng-model="mobileNum">              </label>            </div>            <div class="col col-40 col-code">                <input type="button" class="button button-block code-btn" id="get_num_btn" ng-click="getCode()" ng-value="info" ng-disabled="isDisabled">            </div>          </div>          <label class="item item-input">            <input type="text" placeholder="验证码" name="check_num" id="check_num" ng-model="codeNum">          </label>          <button class="button button-block button-my-style" id="submit_btn" ng-click="submit()" ng-disabled="isSubmitted">提 交</button>        </div>      </div>    </div>

关键CSS代码：

.col-form{  padding: 5% 2%;  margin-bottom: 10%;}.col-form .list label{   margin-bottom:0.2rem;   border-radius: 0.5rem;}.col-form .list input{  font:normal 1rem fzltxhjw;}.item-my-style{  padding: 0.5rem;}.row-code{  padding-left: 0;  padding-right: 0;}.button.code-btn{  margin:0;  border-radius: 0.5rem;  background-color: #ffba07;  color: #51110a;}.col-mobile{  padding-left: 0;}.col-code{  padding-right: 0;}

这里主要是AngularJS的代码部分：

var myApp=angular.module('myApp', ['ionic']);myApp.controller("FirstController",["$scope",function($scope){    //监察手机号    $scope.isDisabled=true;    $scope.mobileNum="";    $scope.mobileVal=function(){        return $scope.mobileNum;    };    $scope.$watch($scope.mobileVal,function(newValue,oldValue){        var regex = /^(13[0-9]|14[0-9]|15[0-9]|17[0-9]|18[0-9])\d{8}$/;        if(regex.test(newValue)){            $scope.isDisabled=false;        }else{            $scope.isDisabled=true;        }    });    //监察验证码    $scope.isSubmitted=true;    $scope.codeNum="";    $scope.codeVal=function(){        return $scope.codeNum;    };    $scope.$watch($scope.codeVal,function(newValue,oldValue){        if(newValue.length==4){            $scope.isSubmitted=false;        }else{            $scope.isSubmitted=true;        }    });    }]);
