AngularJS多步骤表单验证
nie*_*lsv 9 javascript forms validation jquery angularjs
我已经按照本教程使用UI路由器了解AngularJS多步骤表单.表单有效,我可以保存我的数据,但现在我对如何验证表单中的每个步骤有疑问.
我有以下表格与输入字段:
步骤1
- 牌照
第2步
- 名称
- 街
- 邮政编码
- 市
- 电子邮件
- 电话
第3步
- 从日历中选择日期和时间
看起来有点像这样:
我有这样一般的基本视图:
<body ng-app="formApp">
<div id="top"></div>
<div class="container">
<!-- views will be injected here -->
<div ui-view></div>
</div>
</body>
在我的app.js中,我有以下内容(不完整,留下非重要的东西):
// app.js
// create our angular app and inject ngAnimate and ui-router
// =============================================================================
angular.module('formApp', ['ngAnimate', 'ui.router', 'ui.calendar'])
// configuring our routes
// =============================================================================
.config(function($stateProvider, $urlRouterProvider, $interpolateProvider) {
$interpolateProvider.startSymbol('<%');
$interpolateProvider.endSymbol('%>');
$stateProvider
// route to show our basic form (/form)
.state('form', {
url: '/form',
templateUrl: 'views/form.html',
controller: 'formController'
})
// nested states
// each of these sections will have their own view
// url will be /form/interests
.state('form.license', {
url: '/license',
templateUrl: 'views/form-license.html'
})
// url will be nested (/form/profile)
.state('form.profile', {
url: '/profile',
templateUrl: 'views/form-profile.html'
})
// url will be /form/payment
.state('form.appointment', {
url: '/appointment',
templateUrl: 'views/form-appointment.html'
})
// url will be /form/success
.state('form.success', {
url: '/success',
templateUrl: 'views/form-success.html'
});
// catch all route
// send users to the form page
$urlRouterProvider.otherwise('/form/license');
})
// our controller for the form
// =============================================================================
.controller('formController', function($scope, $http, $compile, $location, uiCalendarConfig) {
$scope.formData = {};
$scope.formData.profile = {};
$scope.next = function(step){
if(step == 1)
{
}
else if(step == 2)
{
}
};
// function to process the form
$scope.processForm = function(isValid) {
};
});
我的一般form.html:
<!-- form.html -->
<div class="row">
<div class="col-sm-6 col-sm-offset-3">
<div id="form-container">
<form id="appointment-form" name="appointmentform" ng-submit="processForm(appointmentform.$valid)">
<!-- our nested state views will be injected here -->
<div id="form-views" ui-view></div>
</form>
</div>
</div>
</div>
我的表单中的第一步是form-license.html:
<!-- form-license.html -->
<label>Nummerplaat ingeven</label>
<div class="form-group">
<div class="col-xs-8 col-xs-offset-2">
<input required type="text" class="form-control" name="license" ng-model="formData.license">
</div>
</div>
<div class="form-group row">
<div class="col-xs-4 col-xs-offset-4">
<a ng-click="next(1)" ui-sref="form.profile" class="btn btn-next btn-block">
Volgende
</a>
</div>
</div>
但现在我想知道当他们点击下一个按钮时我怎么能验证这个... 它不能使用正常的必需属性.
有人可以帮我这个吗？
更新:
现在我的第一步有以下几点:
<div class="col-xs-4 col-xs-offset-4">
<a ng-click="next(1, processForm)" ui-sref="form.profile" ng-disabled="!licenseValidated" class="btn btn-next btn-block">
Volgende
</a>
</div>
在我的控制器中:
var validateLicense = function (newVal) {
var validated = false;
// Run your custom validation checks
if(newVal)
{
validated = true;
}
return validated;
};
$scope.$watch('formData.license', function (newVal) {
$scope.licenseValidated = validateLicense(newVal);
});
好的,那很有效.但在我的第二步中,我有多个这样的字段:
<div class="profile">
<div class="form-group">
<label class="col-sm-3 control-label" for="name">Name</label>
<div class="col-sm-9">
<input type="text" class="form-control" name="name" ng-model="formData.profile.name">
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label" for="street">Street</label>
<div class="col-sm-9">
<input type="text" class="form-control" name="street" ng-model="formData.profile.street">
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label" for="zipcode">Zipcode</label>
<div class="col-sm-9">
<input type="text" class="form-control" name="zipcode" ng-model="formData.profile.zipcode">
</div>
</div>
<div class="form-group row">
<div class="col-xs-8 col-xs-offset-2">
<a ng-click="next(1)" ui-sref="form.license" class="btn btn-block btn-previous col-xs-3">
VORIGE
</a>
<a ng-click="next(2)" ui-sref="form.appointment" class="btn btn-block btn-next col-xs-3">
Volgende
</a>
</div>
</div>
</div>
我是否需要为每个人创建$ scope.watch？我是否需要将它们添加到按钮的ng-disabled中？
如果没有通过任何验证步骤,您可以简单地禁用下一个按钮.
就像是:
// Inside your controller.
// Don't overload the scope.
// Only assign what will be needed through your HTML or other AngularJS Scopes
var validateLicense = function (newVal) {
// If you are only checking for content to be entered
return (newVal !== '' && newVal !== undefined);
};
var validateInfo = function (newVal) {
if (newVal.length > 0) {
// Check to make sure that all of them have content
for (var i = 0, l = newVal.length; i < l; i++) {
if (newVal[i] === undefined || newVal[i] === '') {
return false;
}
}
// We didn't find invalid data, let's move on
return true;
}
return false;
};
var validateDate = function (newVal) {
var validated = false;
// Run your custom validation checks
return validated;
}
// Initialize the disabled "Next" buttons
$scope.licenseValidated = false;
$scope.infoValidated = false;
// Watch a single item in a form, if filled in we will let them proceed
$scope.$watch('formData.license', function (newVal) {
$scope.licenseValidated = validateLicense(newVal);
});
// Watch a multiple items in a form, if ALL are filled in we will let them proceed
// Note that the order in this array is the order the newVal will be,
// So further validation for formData.number would be on newVal[1]
$scope.$watchGroup(['formData.name', 'formData.number', 'formData.address'], function (newVal) {
$scope.infoValidated = validateInfo(newVal);
});
form-license.html ng-disabled在下一个按钮上添加属性:
<a ng-click="next(1, appointmentform)" ui-sref="form.profile" class="btn btn-next btn-block" ng-disabled="!licenseValidated">
Volgende
</a>
form-info.html重复上述步骤
<a ng-click="next(1, appointmentform)" ui-sref="form.profile" class="btn btn-next btn-block" ng-disabled="!infoValidated">
Volgende
</a>
等等...
