From Angular's documentation it follows that ngSubmit is a preferred way of submitting a form. All pending operations are immediately finished and $submitted
flag is set as well. Whereas listening to ngClick
event does not have the same effect.
从Angular的文档中可以看出,ngSubmit是提交表单的首选方式。所有待处理的操作立即完成,并且还设置了$ submitted标志。而听取ngClick事件却没有同样的效果。
Now I need to submit a form with hotkeys having all the goodies of ngSumbit
approach. Hence I need some way to trigger standard submit workflow.
现在我需要提交一个表格,其中包含具有ngSumbit方法所有优点的热键。因此,我需要一些方法来触发标准提交工作流程。
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:
我在DOM表单上尝试了submit()并且它有效,但是附加到scope的angular的form对象不包含对DOM表单的引用,因此我需要通过jqLite访问它:
var frm = angular.element('#frmId');
frm.submit();
I didn't like this solution for accessing DOM in controller code so I created a directive:
我不喜欢这个在控制器代码中访问DOM的解决方案,所以我创建了一个指令:
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 $submit
method.
使用$ submit方法扩展表单对象。
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:
两种变体都不能用于未知原因。 form.submit()尝试发送数据,不会阻止默认操作。更新1事实证明,Angular会侦听具有type =“input”的元素的click事件。最终我决定触发该元素的click事件:
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?
这个功能有没有开箱即用的解决方案?

Just use event .triggerHandler('submit') on form element.
只需在表单元素上使用事件.triggerHandler('submit')。
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);
}
})
}
};
}]);

You can modify your directive code a bit like:
你可以修改你的指令代码:
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() {
// Parse the handler of submit & execute that.
var fn = $parse(attr.ngSubmit);
$scope.$apply(function() {
fn($scope, {$event: e});
});
};
}
}
};
}
Here you don't have to add wu-submit
everywhere. ng-submit
will work.
在这里你不必在任何地方添加wu-submit。 ng-submit将有效。
