我的多步和提交进入有问题。我已经按照本教程创建了一个多步骤表单。
现在的问题是，当你在第一步中按enter键时，它会提交表单，而这不是目的。
我有一个通用的form。html，像这样:<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>
我还有
form-license.html (step 1)
<!-- 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)" ng-disabled="!licenseValidated" class="btn btn-next btn-block">
Volgende
</a>
</div>
</div>
form-profile.html (step 2)
<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 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)" ng-disabled="!infoValidated" class="btn btn-block btn-next col-xs-3">
Volgende
</a>
</div>
</div>
</div>
form-appointment.html(步骤3)
<div class="appointment">
<!-- form-payment.html -->
<div class="text-center">
<div id="calendar" class="span8 calendar" ui-calendar="uiConfig.calendar" full-calendar ng-model="eventSources"></div>
<div id="appointment_hours">
<div ng-repeat="(key, value) in formData.appointments">
<input id='<% key %>' type='radio' ng-model='formData.appointment_hour' ng-change="change('<% key %>')" name='appointment' value='<% key %>'>
<!-- change int to string -->
<label for='<% key %>'><% key | format_time %></label><br>
</div>
</div>
<div class="form-group row">
<div class="col-xs-8 col-xs-offset-2">
<a ng-click="next(2)" ui-sref="form.profile" class="btn btn-block btn-previous col-xs-3">
VORIGE
</a>
<button type="button" class="btn btn-block btn-next col-xs-3">VOLGENDE</button>
</div>
</div>
</div>
</div>
我的配置和控制器是这样的:

angular.module('formApp', ['ngAnimate', 'ui.router', 'ui.calendar'])

.state('form', {
url: '/form',
templateUrl: 'views/form.html',

// url will be /form/interests

问题是当你在第一步或第二步点击enter时，它提交了表单，数据没有正确发布。它调用函数processForm。但是我只想在最后一步调用processForm函数。
当你在第一步点击回车键的时候，我怎么才能让它在第二步运行呢?我已经尝试禁用输入按钮，但它不工作与指令。
您需要创建一个指令来监听表单上的keydown事件，并防止按下的键为enter keyCode == 13时的默认动作
这是一个DEMO
包括jquery
创建一个指令disable-enter-submit并将其附加到表单
<form id="appointment-form" name="appointmentform" ng-submit="processForm()" disable-enter-submit>
app.directive('disableEnterSubmit', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
// listen to the keydown event on the form and if the pressed ..
//..key is enter then prevent the default action/s which is submitting the form
element.bind("keydown", function(event) {
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
});
}
}
});
这里是一个稍微改进的DEMO
-------------------------- --------------------------
如果按下enter键需要进入下一步
创建控制器变量
var total_steps = 2; // total steps of the form
var current_step = 1; // active step
$scope.next = function(step) {
// if current step is equals to total steps then submit the form
if(current_step == total_steps) {
$scope.processForm();
return;
}
// if step is defined then assign the current_step to step
// else increment the current_step by 1
if (!angular.isUndefined(step)) {
current_step = step;
} else {
current_step++;
}
// load the proper template based on step
$scope.form_fields = 'step' + current_step + '.html';
};
element.bind("keydown", function(event) {
if (event.keyCode == 13) {
// if press enter then call the next() function on the scope
// we need to trigger the digest cycle manually
// because `element.bind("keydown"..` happens out of angular knowledge.
// so i wrapped it in a `$timeout` or you can use `scope.$apply();` after the `scope.next();`
$timeout(function() {
scope.next();
});
event.preventDefault();
return false;
}
});
这里是DEMO
