我制作了一个AngularJS表单,通过指令集成了Stripe。在这里小提琴:https://jsfiddle.net/u5h1uece/。
HTML:
<body ng-app="angularjs-starter">
<script src="https://js.stripe.com/v3/"></script>
<div ng-controller="MainCtrl">
<form name="regForm" id="register-form">
<label>Mail</label>
<input ng-model="reg.email" type="email" name="username">
<div stripe-validator
stripe-complete="stripeCompleted"
stripe-form-id="register-form"></div>
<br>
<button ng-model="reg.btn" ng-disabled="stripeCompleted === false || !regForm.username.$valid">Register</button>
</form>
</div>
</body>
JS:
var app = angular.module('angularjs-starter', []);
app.controller('MainCtrl', function($scope, $rootScope) {
//Init stripe state via controller
$scope.stripeCompleted = false;
});
app.directive('stripeValidator', function() {
return {
restrict: 'A',
template: `
<div id="stripe-wrapper">
<div id="card-element"></div>
</div>
<small id="card-errors" class="text-danger" role="alert">{{ ccErrMsg }}</small>
<input type="hidden" name="stripeToken" ng-value="stripeToken" />`,
scope: {
"stripeComplete": '=',
"stripeFormId": '@',
"stripeError": '=',
"stripeToken": '=',
},
link: function(scope, element, attrs) {
//Init
var stripe = Stripe("pk_test_6pRNASCoBOKtIshFeQd4XMUh");
var elements = stripe.elements();
var card = elements.create("card");
var form = document.getElementById(scope.stripeFormId);
//mount card element https://stripe.com/docs/stripe-js/reference#element-mount
card.mount("#card-element");
//add event listener
card.addEventListener('change', function(event) {
//check for errors
if (event.error) {
scope.ccErrMsg = event.error.message;
} else {
scope.ccErrMsg = '';
}
//check for complete
scope.stripeComplete = event.complete ? true : false;
//apply scope
scope.$apply();
});
//inject form submit event
form.addEventListener("submit", function(event) {
//prevent form submit
event.preventDefault();
//handle token, handle error and form submit forward
stripe.createToken(card).then(function(result) {
if (result.error) {
scope.ccErrMsg = event.error.message;
scope.stripeToken = '';
} else {
scope.ccErrMsg = '';
scope.stripeToken = result.token;
}
//apply scope
scope.$apply();
//forward submit
form.submit();
})
});
}
}
});
我想使用form.submit()
将表单参数和数据发送到我的后端,然后在$http.post()
函数中从那里发回任何数据,而不是使用.then()
。在这种情况下,参数包括reg.email
的值。
我如何设置表单的方式?我更喜欢使用ng-submit
,但如果那不可能,还有另外一种方法吗?
我建议使用component
来包装条纹输入。您可以使用ng-model
指令使此组件工作,以将卡元素传递回父作用域,并将表单验证应用于条带字段。
TL; DR - Here's an example Fiddle
您要做的第一件事是将条带对象创建为服务,以便共享。
app.service('stripe', function () {
return Stripe("pk_test_6pRNASCoBOKtIshFeQd4XMUh");
});
然后,您可以实现条带component
来环绕条带输入并应用自定义ng-model
验证。
app.component('stripe', {
bindings: {
state: '='
},
require: {
model: 'ngModel'
},
controller: function ($element, $timeout, stripe) {
this.$onInit = function () {
var ctrl = this;
// stripe is passed in to controller as a service
var elements = stripe.elements();
var card = elements.create('card');
card.mount($element[0]);
card.addEventListener('change', function (event) {
// Attach the event as the state so it is visible
// to consumers of the stripe component.
ctrl.state = event;
// Set the validity of the stripe on the ng-model
ctrl.model.$setValidity('stripe', event.complete);
// If the stripe is complete set the card element on
// the ng-model, otherwise null out the model value.
if (event.complete) {
ctrl.model.$setViewValue(card);
} else {
ctrl.model.$setViewValue(null);
}
});
}
}
});
然后在主控制器中,您可以在发送表单之前创建条带标记,然后再发送HTTP请求。
app.controller('MainCtrl', function ($scope, $http, stripe) {
$scope.reg = {};
$scope.onChange = function() {
console.log($scope.card);
};
$scope.register = function () {
// Create the stripe token and send the registration
stripe.createToken($scope.card).then(function (result) {
if (result.error) {
console.error(result.error);
} else {
$scope.reg.stripeToken = result.token;
$http.post('request-url', $scope.reg).then(function (response) {
console.log(response);
}).catch(function (err) {
console.error(err);
});
}
});
};
});
现在您只需将stripe
元素添加到模板中,如下所示:
<div ng-app="angularjs-starter" ng-controller="MainCtrl">
<form name="regForm" id="register-form" ng-submit="register()">
<stripe name="card" ng-model="card" state="cardState" ng-change="onChange()" ng-required="true"></stripe>
<button ng-disabled="regForm.$invalid">Register</button>
<span ng-if="regForm.card.$invalid">{{ cardState.error.message }}</span>
</form>
</div>
