From Angular's documentation it follows that ngSubmit is a preferred way of submitting a form. All pending operations are immediately finished and $submitted
flag is set as well. Whereas listening to ngClick
event does not have the same effect.
Now I need to submit a form with hotkeys having all the goodies of ngSubmit
approach. Hence I need some way to trigger standard submit workflow.
I tried submit()
on DOM form and it worked, but angular's form object attached to scope contains no references to DOM form, thus I need to access it through jqLite:
var frm = angular.element('#frmId');
frm.submit();
I didn't like this solution for accessing DOM in controller code so I created a directive:
function wuSubmit() {
return {
require: 'form',
restrict: 'A',
link: function(scope, element, attributes) {
var scope = element.scope();
if (attributes.name && scope[attributes.name]) {
scope[attributes.name].$submit = function() {
element[0].submit();
};
}
}
};
}
which extends form object with $submit
method.
Both variants do not work for yet unknown reason. form.submit()
tries to send data, default action is not prevented.
Update 1
It turns out that Angular listens to click events of elements having type="input"
.
Eventually I decided to trigger click event for that element:
wuSubmit.$inject = ['$timeout'];
function wuSubmit($timeout) {
return {
require: 'form',
restrict: 'A',
link: function (scope, element, attributes) {
var submitElement = element.find('[type="submit"]').first();
if (attributes.name && scope[attributes.name]) {
scope[attributes.name].$submit = submit;
}
function submit() {
$timeout(function() {
submitElement.trigger('click');
});
}
}
};
}
Is there any out of the box solution for this functionality?
Just use event .triggerHandler('submit') on form element.
myApp.directive("extSubmit", ['$timeout',function($timeout){
return {
link: function($scope, $el, $attr) {
$scope.$on('makeSubmit', function(event, data){
if(data.formName === $attr.name) {
$timeout(function() {
$el.triggerHandler('submit'); //<<< This is Important
//equivalent with native event
//$el[0].dispatchEvent(new Event('submit'))
}, 0, false);
}
})
}
};
}]);
Look at http://jsfiddle.net/84bodm5p/
app.directive("form", function(){
return {
require: 'form',
restrict: 'E',
link: function(scope, elem, attrs, form) {
form.doSubmit = function() {
form.$setSubmitted();
return scope.$eval(attrs.ngSubmit);
};
}
};
});
Html:
<form name="myForm" ng-submit="$ctrl.submit()" novalidate>
Then call in controller
$scope.myForm.doSubmit();
