所谓手动验证是通过AngularJS表单的属性来验证，而成为AngularJS表单必须满足两个条件：
1、给form元素加上novalidate="novalidate"；
2、给form元素加上name="theForm"，
如下：
<!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 class="navbar navbar-inverse navbar-fixed-top">
<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.$submitted)">email格式不正确</p>
</div>
<div class="form-group">
<label for="username">Username</label>
<input type="text" class="form-control" id="username" ng-model="formModel.username"/>
</div>
<div class="form-group">
<label for="age">Age</label>
<input type="number" class="form-control" id="age" ng-model="formModel.age"/>
</div>
<div class="form-group">
<label for="sex">Sex</label>
<select name="sex" id="sex" class="form-control" ng-model="formModel.sex">
<option value="">Please choose</option>
<option value="male">Mail</option>
<option value="femail">Femail</option>
</select>
</div>
<div class="form-group">
<label for="password">Password</label>
<input type="text" class="form-control" id="password" ng-model="formModel.password"/>
</div>
<div class="form-group">
<button class="btn btn-primary" type="submit">Register</button>
</div>
<pre>
{{theForm | json}}
</pre>
</form>
</div>
<script src="../node_modules/angular/angular.min.js"></script>
<script src="second.js"></script>
</body>
</html>
{
"$error": {
"required": [
{
"$validators": {},
"$asyncValidators": {},
"$parsers": [],
"$formatters": [
null
],
"$viewChangeListeners": [],
"$untouched": true,
"$touched": false,
"$pristine": true,
"$dirty": false,
"$valid": false,
"$invalid": true,
"$error": {
"required": true
},
"$name": "email",
"$options": null
}
]
},
"$name": "theForm",
"$dirty": false,
"$pristine": true,
"$valid": false,
"$invalid": true,
"$submitted": false,
"email": {
"$validators": {},
"$asyncValidators": {},
"$parsers": [],
"$formatters": [
null
],
"$viewChangeListeners": [],
"$untouched": true,
"$touched": false,
"$pristine": true,
"$dirty": false,
"$valid": false,
"$invalid": true,
"$error": {
"required": true
},
"$name": "email",
"$options": null
},
"sex": {
"$validators": {},
"$asyncValidators": {},
"$parsers": [],
"$formatters": [],
"$viewChangeListeners": [],
"$untouched": true,
"$touched": false,
"$pristine": true,
"$dirty": false,
"$valid": true,
"$invalid": false,
"$error": {},
"$name": "sex",
"$options": null
}
}
以上，凡是有name属性的input都被显示在上面。
在second.js文件中定义了module,controller以及提交表单的方法。
var myApp1 = angular.module('myApp1',[]);
myApp1.controller('myCtrl1', function($scope, $http){
$scope.formModel = {};
$scope.onSubmit = function(){
$http.post('someurl',$scope.formModel)
.success(function(data){
console.log(':)');
})
.error(function(data){
console.log(':(');
});
console.log($scope.formModel);
};
});
以上的表单验证方式好处是可控性强，但相对繁琐。
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。
