AngularJS: Call The Ng-submit Event Outside The Form

April 25, 2023 Post a Comment

I'm a fish in AngularJS and I have this scenario. In normal ways Angular

Solution 1:

Use HTML5's form attribute, here's a sample:

angular.module('app', [])

.controller('MyCtrl', ['$scope', function($scope) {
  $scope.submitted = false;
  
  $scope.confirm = function() {
    $scope.submitted = true;
  };
}]);

form {
  padding:5px;
  border: 1px solid black
}

<!DOCTYPE html>
<html ng-app="app">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
  <meta charset="utf-8">
  <title>JS Bin</title>
</head>
<body ng-controller="MyCtrl">
  
  <form id="myform" ng-submit="confirm()">
    <label for="myinput">My Input</label>
    <input type="text" id="myinput" name="myinput">
  </form>
  <br>
  
  <input type="submit" value="Submit" form="myform">
  
  <p ng-show="submitted">
    The form was submitted
  </p>

</body>
</html>

Solution 2:

Please, surround your code with a ng-controller, and use ng-click on buttons out of scope of <form>.

I make a sample on jsfiddle for you... try it:

http://jsfiddle.net/xKkvj/2/

<div ng-app>
    <div ng-controller="Ctrl">
        <form ng-submit="submit()">Enter text and hit enter:
            <input type="text" ng-model="text" name="text" />
            <input type="submit" id="submit" value="Submit" /> <pre>list={{list}}</pre>
        </form>
        <button ng-click="submit()">Submit 2</button>
    </div>
</div>

with js:

function Ctrl($scope) {
    $scope.list = [];
    $scope.text = 'hello';
    $scope.submit = function () {
        if ($scope.text) {
            $scope.list.push($scope.text);
            $scope.text = '';
        }
    };
}

Solution 3:

This is by far the cleanest solution I found, all credits go to @Offereins https://stackoverflow.com/a/23456905/3819736

<form ng-submit="vm.submit()">
    <input type="text" name="name" />
    <input type="submit" id="submit-form" class="hidden" />
</form>
<label for="submit-form">
    <button type="submit">submit</button>
</label>

This method doesn't require any additional controller JS or other jQuery tweaks.

Solution 4:

Angular 2

For anyone looking to achieve the same with Angular 2, ngForm exposes an event emitter you can use.

https://angular.io/api/forms/NgForm

<form role="form" (ngSubmit)="onSubmit()" #myForm="ngForm">
<div class="form-group">
    <label for="name">Name</label>
    <input autofocus type="text" ngControl="name" #name="ngForm" class="form-control" id="name" placeholder="Name">
    <div [hidden]="name.valid || name.pristine" class="alert alert-danger">
        Name is required
    </div>
</div>
</form>
<button type="submit" class="btn btn-primary" (click)="myForm.ngSubmit.emit()">Add</button>

You can also perform the same emit from inside your component ts/js file

All great answers, but the uber-solution, with all your options laid out: http://plnkr.co/edit/VWH1gVXjP2W9T9esnVZP?p=preview

  <form ng-submit="submit()" name="jForm" id="jForm" onsubmit="event.returnValue = false; return false;">
    <input type="text" class="form-control" placeholder="try to hit the enter key in here" />
    <div class="btn btn-default" id="tap">
      Tap me
    </div>

    <div ui-submit="" class="btn btn-primary">Submit form</div>
  </form>
  <ui-submitform class="btn btn-primary" formsubmitfunction="submit()">Submit form 2</ui-submitform>
  <button onclick="$('#jForm').submit()">jquery Submit</button>

and extending @m-k's and combing ideas from @joaozito-polo:

app.directive('uiSubmitform', function()
{
    // need this to make sure that you can submit your form by simply pressing the enter key in one of the input fields
    return {
     restrict: 'E',
     link: function(scope, element, attrs)
     {
        element.onTrigger(function()
        {
          //scope.$apply(attrs.formsubmitfunction); 
            scope.$eval(attrs.formsubmitfunction);
        });
     }
 };
});
