AngularJS:在表单外调用ng-submit事件

[英]AngularJS: Call the ng-submit event outside the form

I'm a fish in AngularJS and I have this scenario. 我是AngularJS的鱼,我有这个场景。

<form>
    <input type="text">
</form>
<button type="submit">submit</button>

In normal ways AngularJS provides the ng-submit directive to work as an attribute in the form but I need to call it outside. 在正常情况下,AngularJS提供ng-submit指令作为表单中的属性,但我需要在外面调用它。

So, someone has experienced the same problem? 那么,有人遇到过同样的问题吗? If yes, what you did? 如果是的话,你做了什么?

Use HTML5's form attribute, here's a sample: 使用HTML5的form属性,这是一个示例:

 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> 

Please, surround your code with a ng-controller, and use ng-click on buttons out of scope of <form>. 请使用ng-controller包围您的代码,并使用ng-单击<form>范围之外的按钮。

I make a sample on jsfiddle for you... try it: 我在jsfiddle上为你做一个样本...试试吧:

http://jsfiddle.net/xKkvj/2/ 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: 与js:

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

This is by far the cleanest solution I found, all credits go to @Offereins https://stackoverflow.com/a/23456905/3819736 这是迄今为止我找到的最干净的解决方案,所有信用都归@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. 此方法不需要任何其他控制器JS或其他jQuery调整。

Angular 2 Angular 2

For anyone looking to achieve the same with Angular 2, ngForm exposes an event emitter you can use. 对于希望使用Angular 2实现相同功能的任何人,ngForm会公开您可以使用的事件发射器。

https://angular.io/api/forms/NgForm 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 您还可以从组件ts / js文件中执行相同的发射

Here is my test code. 这是我的测试代码。 The controller who has the login method is already called! 已经调用了具有登录方法的控制器!

<form ng-submit="login()" id="form-test" name="formTest">
    <input type="text" name="username">
    <br>
    <input type="password" name="userpass">
    <br>

    <!-- works -->
    <input type="submit" value="submit inside" id="test">
</form>

<!-- change the path from /#/login to /?username=aaa&userpass=aaa#/login and reloads the page-->
<button type="submit" onclick="$('#form-test').submit();">submit outside (jquery)</button> 

<!-- doesn't work -->
<button type="submit" ng-click="formTest.submit()">submit outside (ng-click)</button> 

All great answers, but the uber-solution, with all your options laid out: http://plnkr.co/edit/VWH1gVXjP2W9T9esnVZP?p=preview 所有伟大的答案,但超级解决方案,所有选项都列出: 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 @mk's and combing ideas from @joaozito-polo: 并扩展@ mk并从@ joaozito-polo中梳理思路:

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);
        });
     }
 };
});

Easiest way for me create special directive for external submission. 对我来说最简单的方法是为外部提交创建特殊指令。

Important only use right event .triggerHandler('submit') on form element 重要的是仅在表单元素上使用权限事件.triggerHandler('submit')

$scope.$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 my answer here How to trigger form submit programmatically in AngularJS? 看看我在这里的答案如何在AngularJS中以编程方式触发表单提交?

如果你正在寻找提交状态的句柄:在函数ng-click中只需添加vm.formName。$ setSubmitted();

ng-click="vm.formName.$setSubmitted(); vm.submit()"

There is a solution that works for me: 有一个适合我的解决方案:

http://jsbin.com/ODaFaGU/3/edit http://jsbin.com/ODaFaGU/3/edit

Check out the PART 2 and PART 3. 查看第2部分和第3部分。

There are two solutions inside. 里面有两个解决方案。

One for the regular form submit buttons - it allows you to tap the buttons without a delay, but also ensures that pressing the "enter" key in any of the form fields will trigger a submit. 一个用于常规表单提交按钮 - 它允许您毫不拖延地点击按钮,但也确保在任何表单字段中按“输入”键将触发提交。

Secondly there is an additional eventHandler that combines the click, tap and keydown[enter] events into a single one - this ensures that you can hit your controls as well with the keyboard, as with a click on desktop, and a tap on mobile(without hitting the click event twice) devices. 其次还有一个额外的eventHandler,它将click,tap和keydown [enter]事件组合成一个 - 这可以确保您可以通过键盘点击控件,就像点击桌面一样,然后点击移动设备(没有点击两次点击事件)设备。

If you have any problems with this, give me a comment, I'll fix it. 如果你有任何问题,请给我一个评论,我会解决它。

In Angular you don't submit forms (well, at least in the angular way). 在Angular中,您不提交表单(好吧,至少以有角度的方式)。 You just need a function that will do what you want to do when you complete the form. 您只需要一个能够在完成表单时执行您想要执行的操作的功能。

Just call that function in your <button> and you're ready to go. 只需在<button>调用该功能,即可开始使用。
