Il existe environ deux types de validation de formulaire dans AngularJS, l'une est la validation manuelle et l'autre est la validation automatique.
1. Vérification manuelle
La vérification dite manuelle consiste à vérifier via les attributs du formulaire AngularJS. Pour devenir un formulaire AngularJS, deux conditions doivent être remplies :
1. Ajoutez novalidate="novalidate" à l'élément de formulaire
2. Ajoutez name="theForm" à l'élément de formulaire, comme suit :
<!DOCTYPE html>
<html lang="en" ng-app="myApp1">
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="../node_modules/bootstrap/dist/css/bootstrap.min.css"/>
<link rel="stylesheet" href="../css/main.css"/>
</head>
<body>
<nav >
<div class="container">
<div class="navbar-header">
<a href="/" class="navbar-brand">Form Submitting</a>
</div>
</div>
</nav>
<div class="container main-content" ng-controller="myCtrl1">
<!--novalidate让表单不要使用html验证-->
<!--theForm变成scope的一个字段-->
<form ng-submit="onSubmit(theForm.$valid)" novalidate="novalidate" name="theForm">
<div class="form-group">
<label for="name">Name</label>
<input type="text" class="form-control" id="name" ng-model="formModel.name"/>
</div>
<div class="form-group" ng-class="{
'has-error': !theForm.email.$valid && (!theForm.$pristine || theForm.$submitted),
'has-success': theForm.email.$valid && (!theForm.$pristine || theForm.$submitted)
}">
<label for="email">Email</label>
<input type="email" class="form-control" id="email" ng-model="formModel.email" required="required" name="email"/>
<p class="help-block" ng-show="theForm.email.$error.required && (!theForm.$pristine || theForm.$submitted)">必填</p>
<p class="help-block" ng-show="theForm.email.$error.email && (!theForm.$pristine || theForm.$submitted)">email格式不正确</p>
