AngularJS自动表单验证
AngularJS的另外一种表单验证方式是自动验证,即通过directive来实现,除了AngularJS自带的directive,还需要用到angular-auto-validate这个第三方module。
有关angular-auto-validate:
- 安装:npmiangular-auto-validate
- 引用:<scriptsrc="../node_modules/angular-auto-validate/dist/jcs-auto-validate.min.js"></script>
- module依赖:varmyApp=angular.module("app",["jcs-autoValidate"]);
为了实现错误信息本地化,还需要angular-localize这个第三方module:
- 安装:npminstallangular-localize--save
- module依赖:varmyApp=angular.module("app",["localize"]);
- 引用:
<scriptsrc="../node_modules/angular-sanitize/angular-sanitize.min.js"></script> <scriptsrc="../node_modules/angular-localize/angular-localize.min.js"></script>
此外,当点击提交表单按钮,需要禁用按钮并显示一种等待效果,需要用到angular-ladda这个第三方module:
- 安装:bowerinstallangular-ladda--save
- module依赖:varmyApp=angular.module("app",["angular-ladda"]);
- 引用:
<linkrel="stylesheet"href="../bower_components/ladda/dist/ladda-themeless.min.css"/> <scriptsrc="../bower_components/ladda/dist/spin.min.js"></script> <scriptsrc="../bower_components/ladda/dist/ladda.min.js"></script> <scriptsrc="../bower_components/angular-ladda/dist/angular-ladda.min.js"></script>
页面如下:
<html> <head> <metacharset="gb2312"> <title></title> <linkrel="stylesheet"href="../node_modules/bootstrap/dist/css/bootstrap.min.css"/> <linkrel="stylesheet"href="../bower_components/ladda/dist/ladda-themeless.min.css"/> <linkrel="stylesheet"href="../css/main.css"/> </head> <body> <navclass="navbarnavbar-inversenavbar-fixed-top"> <divclass="container"> <divclass="navbar-header"> <ahref="/"class="navbar-brand">FormValidatingAuto</a> </div> </div> </nav> <divclass="containermain-content"ng-controller="myCtrl1"> <!--novalidate让表单不要使用html验证--> <!--theForm变成scope的一个字段--> <formng-submit="onSubmit()"novalidate="novalidate"> <divclass="form-group"> <labelfor="name"class="control-label">Name</label> <inputtype="text"class="form-control"id="name"ng-model="formModel.name"required="required"/> </div> <divclass="form-group"> <labelfor="email"class="control-label">Email</label> <inputtype="email"class="form-control"id="email"ng-model="formModel.email"required="required"/> </div> <divclass="form-group"> <labelfor="username"class="control-label">Username</label> <inputtype="text" class="form-control" id="username" ng-model="formModel.username" required="required" ng-pattern="/^[A-Za-z0-9_]{1,32}$/" ng-minlength="7" ng-pattern-err-type="badUsername" /> </div> <divclass="form-group"> <labelfor="age"class="control-label">Age</label> <inputtype="number" class="form-control" id="age" ng-model="formModel.age" required="required" min="18" max="65" ng-min-err-type="tooYoung" ng-max-err-type="tooOld" /> </div> <divclass="form-group"> <labelfor="sex"class="control-label">Sex</label> <selectname="sex"id="sex"class="form-control"ng-model="formModel.sex"required="required"> <optionvalue="">Pleasechoose</option> <optionvalue="male">Mail</option> <optionvalue="femail">Femail</option> </select> </div> <divclass="form-group"> <labelfor="password"class="control-label">Password</label> <inputtype="text"class="form-control"id="password"ng-model="formModel.password"required="required"ng-minlength="6"/> </div> <divclass="form-group"> <!--<buttonclass="btnbtn-primary"ng-click="onSubmit()">Register</button>--> <buttonclass="btnbtn-primary" ladda="submitting" data-style="expand-right" type="submit"> <spanng-show="submitting">正在注册...</span> <spanng-show="!submitting">注册</span> </button> </div> <pre> {{formModel|json}} </pre> </form> </div> <scriptsrc="../node_modules/angular/angular.min.js"></script> <scriptsrc="form_validation_auto.js"></script> <scriptsrc="../node_modules/angular-auto-validate/dist/jcs-auto-validate.min.js"></script> <scriptsrc="../node_modules/angular-sanitize/angular-sanitize.min.js"></script> <scriptsrc="../node_modules/angular-localize/angular-localize.min.js"></script> <scriptsrc="../bower_components/ladda/dist/spin.min.js"></script> <scriptsrc="../bower_components/ladda/dist/ladda.min.js"></script> <scriptsrc="../bower_components/angular-ladda/dist/angular-ladda.min.js"></script> </body> </html>
先看提交按钮:
<divclass="form-group"> <!--<buttonclass="btnbtn-primary"ng-click="onSubmit()">Register</button>--> <buttonclass="btnbtn-primary" ladda="submitting" data-style="expand-right" type="submit"> <spanng-show="submitting">正在注册...</span> <spanng-show="!submitting">注册</span> </button> </div>
- ladda属性值为bool值,true表示显示动态等待效果,false不显示动态等待效果,这里的submitting是scope中的一个属性
- data-style="expand-right"表示在按钮的右侧显示动态等待效果
再拿表单中的Age字段来说:
<divclass="form-group"> <labelfor="age"class="control-label">Age</label> <inputtype="number" class="form-control" id="age" ng-model="formModel.age" required="required" min="18" max="65" ng-min-err-type="tooYoung" ng-max-err-type="tooOld" /> </div>
其中,min,max为AgularJS的directive,而ng-min-err-type是angular-auto-validate的directive。这里遵循的惯例是ng-AngularJS表单验证的directive名称-err-type,而tooYoung和tooOld的作用是什么,又是在哪里用上了呢?
是在module层面用上了,定义在了form_validation_auto.js文件中。
varmyApp1=angular.module('myApp1',['jcs-autoValidate','localize','angular-ladda']); myApp1.run(function(defaultErrorMessageResolver){ defaultErrorMessageResolver.getErrorMessages().then(function(errorMessages){ errorMessages['tooYoung']='年龄必须小于{0}'; errorMessages['tooOld']='年龄不能大于{0}'; errorMessages['badUsername']='用户名只能包含数字、字母或下划线'; }); }); myApp1.controller('myCtrl1',function($scope,$http){ $scope.formModel={}; $scope.submitting=false; $scope.onSubmit=function(){ $scope.submitting=true; console.log('已提交'); console.log($scope.formModel); $http.post('url',$scope.formModel) .success(function(data){ console.log(':)'); $scope.submitting=false; }) .error(function(data){ console.log(':('); $scope.submitting=false; }); }; });
以上就是本文的全部内容,希望对AngularJS手动表单验证能够熟练操作。
