Ember.js TextField action submits form - javascript

I have the following form:
<form class="form-horizontal" {{action "formSubmit"}}>
<div class="form-group">
<label>User:</label>
{{input type="text" value=user action="findUser"}}
</div>
<div class="form-group">
<label>Notes:</label>
{{input type="text" value=notes}}
</div>
<button type="submit" class="btn btn-primary">Save</button>
</form>
As you notice, I have two actions for this form:
When I type on the user input field and press enter, it fires the findUser action
When the form submits, the formSubmit action is called.
Now, here's the problem.
When I type something on the user text field and press enter, it fires the findUser action but also fires the formSubmit. As I know, this is how a form normally behaves. When you press enter on a text field, it submits the form.
Is there a workaround on this behavior? That when I press enter on a the user text field, I want the findUser action to be fired but not submit the form.
Please help.

One workaround is removing form itself. You can have action on button. You may have to sacrifice some form related features but still works very well. Here is the jsbin.

There might be some other better way as well.
<div class="form-group">
<label>User:</label>
{{input type="text" value=user action="findUser" bubbles=false}}
</div>
<div class="form-group">
<label>Notes:</label>
{{input type="text" value=notes}}
</div>
<button type="submit" class="btn btn-primary" {{action "formSubmit"}}>Save</button>
and javascript
App.IndexController = Ember.Controller.extend({
actions: {
findUser: function(){
console.log('Find User');
},
formSubmit: function(){
console.log('Form Submit');
}
}
});

Another workaround that allows using the form:
http://emberjs.jsbin.com/povud/1/
Just add 'onkeypress="return event.keyCode != 13;"' to the form element and place the {{action}} on the button itself:
<form class="form-horizontal" onkeypress="return event.keyCode != 13;">
<div class="form-group">
<label>User:</label>
{{input type="text" value=user action="findUser"}}
</div>
<div class="form-group">
<label>Notes:</label>
{{input type="text" value=notes}}
</div>
<button class="btn btn-primary" {{action "formSubmit"}}>Save</button>
</form>

How to validate HTML elements when submitting through JQuery?

I have an HTML form as shown below with some form fields and a submit and a delete button:
There is also a floating component which appears whenever there are changes in the form as shown in the same diagram with text: You have unsaved changes. This is a common component which appears for all the forms in my website.
When I submit the form using the form's Submit button, it validates all the fields as per the validations.
(for example: <input type="number" min="0"> will check that the number should be positive)
But if I submit the form from the Save button on the floating element, it does not checks for any validation, and just posts the request.
I tried using the following code, but the reportValidity() function doesn't do anything.
if (!form.checkValidity()) {
form.reportValidity();
}
form.checkValidity() and form.reportValidity() both are returning false when I do a console.log.
What am I missing here, and how can I fix this?
P.S. I tried this on chrome v98.
Edit: Adding HTML code:
<form method="post" action="/products/manage/{{.Product.ID}}/submit/">
<div class="form-group col-md-5">
<label>Product Quantity</label>
<input type="number" min="0" name="ProductQuantity" value="{{if .Product}}{{.Product.Qunatity}}{{else}}10{{end}}">
</div>
<button type="submit" class="btn btn-success" value="Submit">Submit</button>
<button type="submit" class="btn btn-danger" value="Delete" formaction="/products/manage/{{.Product.ID}}/delete/">Delete</button>
</form>
Save button calls this function:
function submitForm(form, url) {
const form = $(form)[0]
if (!form.checkValidity()) { //<- Added the code here
form.reportValidity();
}
var serialized = serializeForm(form);
// Do some more things then use HTTP to request the API
}
You can easily use the jQuery event handlers do the work for you.
A simplified example below:
Give your form some identifier (example: id="form1")
Catch the click event on button click
Trigger the submit event to submit that form
$('.unsavedChangesBtn').on('click',function(){
$('#form1').submit();
});
In below example you can submit the form either by clicking the submit button or the save button.
$('document').ready(function(){
$('#form1').on('submit',function(){
alert("SUBMITTED");
});
$('.unsavedChangesBtn').on('click',function(){
$('#form1').submit();
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form method="post" id="form1" action="javascript:void(0);">
<div class="form-group col-md-5">
<label>Product Quantity</label>
<input type="number" min="0" name="ProductQuantity" value="{{if .Product}}{{.Product.Qunatity}}{{else}}10{{end}}">
</div>
<button type="submit" class="btn btn-success" value="Submit">Submit</button>
<button type="submit" class="btn btn-danger" value="Delete" formaction="/products/manage/{{.Product.ID}}/delete/">Delete</button>
</form>
<button class="unsavedChangesBtn"> SAVE </button>

Prevent angular form from submitting if input is blank

I have an Angular form inside a ng2 popup:
<popup>
Sign up for our Newsletter! <form #f="ngForm" (ngSubmit)="onSubmit()" novalidate>
</button> <input type="email"/>
<button>Submit</button>
</form>
</popup>
<button class="submit" (click)="ClickButton()">Sign up for our Newsletter </button>
here is the onClick event function:
constructor(private popup:Popup) { }
testAlert() { ClickButton(){
alert("Newsletter event works"); this.popup.options = {
widthProsentage: 15,
showButtons: false,
header: "Sign up for our Newsletter!",
}
this.popup.show(this.popup.options);
}
It works fine but I am able to submit her even if the input is blank, how can I make so that it does not submit if it is clicked empty
I tried using RegEx but it did not work
Consider adding validation.
Something like this:
<div class="form-group row">
<label class="col-md-2 col-form-label"
for="userNameId">User Name</label>
<div class="col-md-8">
<input class="form-control"
id="userNameId"
type="text"
placeholder="User Name (required)"
required
(ngModel)="userName"
name="userName"
#userNameVar="ngModel"
[ngClass]="{'is-invalid': (userNameVar.touched || userNameVar.dirty) && !userNameVar.valid }" />
<span class="invalid-feedback">
<span *ngIf="userNameVar.errors?.required">
User name is required.
</span>
</span>
</div>
</div>
You can then disable the submit button if the fields are not valid:
<button class="btn btn-primary"
type="submit"
style="width:80px;margin-right:10px"
[disabled]="!loginForm.valid">
Log In
</button>
(ngSubmit) is built-in event emitter inside of Angular ngForm and is directly related to button element which is kind of a trigger for form submission.
Therefore, as lealceldeiro said, you only need onSubmit function and button intended for submission inside of your form tag.
Please provide live demo so we can see the whole file (.ts particularly).
Setting the validation properly depends on what kind of forms you're going to use (template or ReactiveForms).
See more about proper ngForm usage in official documentation.

Onkeypress function not working on bootstrap input box

I've been trying to code a function that goes to a different page when the user hits the enter key into a certain input box. Here's the code:
<div class="container">
<div class="row">
<form>
<div id="search" onkeypress="enter(event)" >
<div class="input-group col-md-offset-8 col-md-3">
<input type="text" class="form-control">
<div class="input-group-btn">
<i class="glyphicon glyphicon-search"></i>
</div>
</div>
</div>
</form>
</div>
</div>
<script>
function enter(event){
if (event.keyCode == 13){
document.location.href = "newpage.com";
}
}
</script>
Thanks in advance!
What's happening is simple, you have a "form" tag, so when you hit enter, "onkeypress" is firing the event and the function "enter" that you created is handling that event, but having a "form" tag it just submitting a form.
To avoid that, just remove the "form" tag or just replace it for the following:
<form onsubmit="event.preventDefault();">
Also, you have to add the protocol if you want to redirect to a different page, like:
document.location.href = "http://newpage.com";
I hope it helps :)

Pressing Enter doesn't work with AngularJS

I am having a problem with using 'enter button' on the keyboard with an angular js login form. I know this question is asked before but I believe that my problem is a bit different because I tried almost everything written on the stackoverflow questions.
So, I just want to be able to hit enter and submit the form with only using the enter key on keyboard.
Here is login html:
<!-- BEGIN LOGIN FORM -->
<form ng-submit="loginCtrl.login()" class="login-form">
<h3 class="form-title">Sign In</h3>
<div class="alert alert-danger display-hide">
<button class="close" data-close="alert"></button>
<span>
Enter any username and password. </span>
</div>
<div class="form-group">
<!--ie8, ie9 does not support html5 placeholder, so we just show field title for that-->
<label class="control-label visible-ie8 visible-ie9">Username</label>
<input class="form-control form-control-solid placeholder-no-fix" type="text" autocomplete="off" placeholder="Company/username"
ng-model="loginCtrl.username" name="username"/>
</div>
<div class="form-group">
<label class="control-label visible-ie8 visible-ie9">Password</label>
<input class="form-control form-control-solid placeholder-no-fix" type="password" autocomplete="off" placeholder="Password"
ng-model="loginCtrl.password" name="password"/>
</div>
<div class="form-actions">
<input type="submit" class="btn btn-success uppercase" value="Login">
</div>
</form>
<!-- END LOGIN FORM -->
and here is my login:
self.login = function() {
var result = self.username.split("/");
var account = result[0];
var userId = result[1];
UserService.login(userId, self.password,account).then(function(user) {
self.userAccount = user;
$state.go('home');
}, function(err) {
alert("Authentication failure: Please check your credentials. ")
});
I get user name as "companyName/Username" so it is like:
amazon/bigboby
I'm pretty sure your problem is caused by this <button> tag:
<button class="close" data-close="alert"></button>
The answer is found in the documentation:
You can use one of the following two ways to specify what javascript method should be called when a form is submitted:
ngSubmit directive on the form element
ngClick directive on the first button or input field of type submit (input[type=submit])
Note the comment about how it looks for an ng-click handler on the first button. When you are pressing ENTER to submit the form, Angular looks at the form and sees that button. It would execute the ng-click handler on that button (if it had one).
If you include the type attribute on the button, you can prevent that and let it find the actual submit button:
<button type="button" class="close" data-close="alert"></button>

Angular blur validation preventing submission of separate form

I have an Angular page with a form for adding people, and a button (outside this form) to submit the list of people.
When the user focuses on a text input in the form, and then clicks to submit the list, the validation error from the text input appears but the submit event never occurs.
An example of this issue here: http://plnkr.co/edit/6Z0UUs
<div ng-controller="MyCtrl as vm">
<form name="form1" novalidate="">
<input type="text" name="field1" ng-model="vm.name" required>
<div ng-messages="form1.field1.$error" ng-if="form1.field1.$touched">
<label ng-message="required">Name is required</label>
</div>
<!--
This form adds a person to a list. I've not included this code to keep the example simple
<input type="submit" value="Add person">
-->
</form>
<button ng-click="vm.submit()">Submit list</button>
</div>
-
angular.module('myApp',[])
.controller('MyCtrl', function() {
var vm = this;
vm.name = '';
vm.submit = function () {
alert('submitted');
};
});
To replicate:
Click on the text input but leave blank
Click submit
Current behavior: "Name is required" appears thanks to the validation. Clicking 'Submit' again displays the 'submitted' alert.
Expected behavior: "Name is required" appears thanks to the validation and the 'submitted' alert appears.
Desired behavior: The 'submitted' alert appears and I add some code to vm.submit() to hide the 'Name is required' validation message as it's not important when the list is submitted.
I've observed that removing the ng-messages block fixes the issue, but I do need to show a validation message. Using a more basic directive (ng-show) to show the validation message instead does not help.
Any insights into what I'm doing wrong, or workarounds to achieve my desired behavior, would be great!
[Modified Answer] :
Here is a working plunker : http://plnkr.co/edit/JCyRi8xp4L3FtafABblS?p=preview
vm.preventDefaultIfSubmitted = function($event){
if($event.relatedTarget.id == "submit"){
$event.stopImmediatePropagation();
}
};
The idea is to get the $event when the blur occurs and then to look at the id of the relatedTarget (which is your button in this case) and if it is then you cancel the $event, otherwise you keep it.
That way if you click anywhere your validation message appears and if you click on submit it doesnt
May this help for form validation
