Cho*_*ken 4 html javascript validation angularjs
我正在尝试使用Angularjs验证来在列表中至少输入一个输入时启用按钮.我正在研究的内容类似于以下w3schools示例:
<head>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
</head>
<body>
<h2>Validation Example</h2>
<form ng-app="myApp" ng-controller="validateCtrl" name="myForm" novalidate>
<p>Username:<br>
<input type="text" name="user" ng-model="user" required>
<span style="color:red" ng-show="myForm.user.$dirty && myForm.user.$invalid">
<span ng-show="myForm.user.$error.required">Username is required.</span>
</span>
</p>
<p>Email:<br>
<input type="email" name="email" ng-model="email" required>
<span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
<span ng-show="myForm.email.$error.required">Email is required.</span>
<span ng-show="myForm.email.$error.email">Invalid email address.</span>
</span>
</p>
<p>
<input type="submit" ng-disabled="myForm.user.$dirty && myForm.user.$invalid || myForm.email.$dirty && myForm.email.$invalid>"
</p>
</form>
<script>
var app = angular.module('myApp', []);
app.controller('validateCtrl', function($scope) {
$scope.user = 'John Doe';
$scope.email = 'john.doe@gmail.com';
});
</script>
</body>
我尝试添加一个div包含两个带有"required"标签的输入,如下所示,但无济于事:
<div name="address" ng-model="address" required>
<input name="address1" ng-model="address1">
<input name="address2" ng-model="address2">
使用角度验证执行此操作的最佳方法是什么？

在NG-所需的指令可以帮助您为这个如有条件要求的需要.
例如:
<div name="addresses">
<input name="address1" ng-model="address1" ng-required="!address2">
<input name="address2" ng-model="address2" ng-required="!address1">
</div>
