I have my chat and I dont want people to send empty message so I would like that my input become required. Thanks for your help.
I tried to put "required='required'" in the input line, I also tried veeValidate but it broke my chat when I use it, I also tried to put "Required = true" in Props and data but without a good result
This is ChatForm.vue
<template>
<div class="input-group" >
<input id="btn-input" type="text" name="message" class="form-control input-sm" placeholder="Ecrire..." v-model="newMessage" #keyup.enter="sendMessage">
<span class="input-group-btn">
<button class="btn btn-primary btn-sm" id="btn-chat" #click="sendMessage">
✓
</button>
</span>
</div>
</template>
<script>
export default {
props: ['user'],
data() {
return {
newMessage: '',
}
},
methods: {
sendMessage() {
this.$emit('messagesent', {
user: this.user,
message: this.newMessage
});
setTimeout(function() {
const messages = document.getElementById('mess_cont');
messages.scrollTop = messages.scrollHeight;
}, 200);
this.newMessage = '';
}
}
}
</script>
And this is my form in the app.blade.php
<div id="app" class="container-chat">
<div class="row">
<div class="col-md-12 col-md-offset-2">
<div class="col-md-12 col-md-offset-2">
<div class="panel-body panel-content" id="mess_cont">
<chat-messages id="mess" :messages="messages" :currentuserid="{{Auth::user()->id}}"></chat-messages>
</div>
<div class="panel-footer">
<chat-form
v-on:messagesent="addMessage"
:user="{{ Auth::user() }}"
></chat-form>
</div>
</div>
</div>
</div>
</div>
Try to change your ChatForm.vue like this:
<template>
<form #submit.prevent="sendMessage">
<div class="input-group" >
<input id="btn-input" type="text" name="message" class="form-control input-sm" placeholder="Ecrire..." v-model="newMessage" required>
<span class="input-group-btn">
<button class="btn btn-primary btn-sm" type="submit" id="btn-chat">
✓
</button>
</span>
</div>
</template>
You are not treating the input in the correct way, the input which is required needs to be inside a form and the required keyword will prevent the form submission if the input field is empty.
There are a few things I would do differently.
1/ Wrap your chat form in a tag, and execute the sendMessage() method on submit. This will give your users a nicer experience, as they can just to submit the message.
2/ Convert the button into a submit button so it triggers the form.submit event.
3/ You can easily disable the button by checking whether newMessage has contents. I don't think you need vee validate or anything else to achieve this; for something as simple as a chat form, your user doesn't need much more feedback than seeing a disabled button to realise (s)he needs to write something first.
4/ in the addMessage method you can just check the contents of newMessage and not do anything when it's empty. This is perfectly fine because you already hinted the user by disabling the button too.
I think this is a subtle way where you guide your user, but don't overdo it.
Please add name attributes to all of your form elements. Some of the element in my form had name attribute and some didn't. Element which had name attributes worked correctly but the one's which didn't had name failed.

EDIT: I am using Symfony forms to create the form but not sure if that is relevant
I am validating a textarea element to check for only whitespace, and throwing an error if there are no characters. The check works and is triggered by the submit button. However, if the validation message triggers, it will keep appearing every time I type, even if it is not whitespace.
This is my JS file
jQuery(document).ready(function () {
//the submit button is #announcement_create_save
$('#announcement_create_save').click(function () {
var content = $('#announcement_create_content').val();
// The regex which checks if the field only has whitespace
if (!(/.*\S+.*/.test(content))) {
document.getElementById('announcement_create_content').setCustomValidity('Please fill out this field.');
}
else {
document.getElementById('announcement_create_content').setCustomValidity("");
}
})
});
HTML
<form name="announcement_create" method="post">
<div class="announcement-card-body">
<label for="announcementText" class="content-label">Announcement (Supports Markdown)</label>
<textarea id="announcement_create_content" name="announcement_create[content]" required="required" class="form-control announcement-text" rows="5" name="content" maxlength="2000"></textarea>
</div>
</div>
</div>
<div class="card-footer border-0 bg-white pt-0">
<div>
<button type="submit" id="announcement_create_save" name="announcement_create[save]" class="btn btn-primary"><span class="fas fa-check"></span> Post announcement </button>
<button type="button" class="btn btn-light" data-dismiss="modal" aria-label="Close">Cancel
</button>
</div>
</div>
</form>
After validation is fired a popup notification of validation is displayed for a few seconds
Wait until this validation message is fired and after that try to enter the textarea.
Alert will not fire every time while typing it takes delay due to javascript load for few secounds.
I have two forms on a page that are identical, but I'm trying to validate the one field (which is email in this case), but I can't seem to get it to just validate the one input field as it just shows the error for both forms.
HTML:
<div class="general-form">
<div class="email-error" style="display:none;">
<p>You need valid email</p>
</div>
<div class="form-wrap">
<div class="form-row">
<input id="from-email" type="email" name="email" placeholder="Your Email" />
</div>
<div class="btn-row">
<button class="submit-btn">Submit</button>
</div>
</div>
</div>
<div class="general-form">
<div class="email-error" style="display:none;">
<p>You need valid email</p>
</div>
<div class="form-wrap">
<div class="form-row">
<input id="from-email" type="email" name="email" placeholder="Your Email" />
</div>
<div class="btn-row">
<button class="submit-btn">Submit</button>
</div>
</div>
</div>
JS:
$(".submit-btn").on("click", function() {
var $this = $(this);
var valid_email = $this.find("#from-email").val();
if (/(.+)#(.+){2,}\.(.+){2,}/.test(valid_email)) {
return true;
} else {
$this.parents().find(".email-error").show();
return false;
}
});
Overall, I can get it to pass through the validation, but the error message shows for both forms and I'm not sure how to get it so it only shows the error message for that particular form. I'm guessing that I'm pushing too far up the chain and it's testing for both of the forms, but I can't remember which one to target specifically if that makes any sense.
You doubled the id from-email that’s why. In your JS you are checking all fields with the id from-email in this case both of the inputs are checked because both the id.
If one of them is wrong you are searching for the email-error in all of your parents which will go up to the body and then find all off the error wrappers. $this.parents(“.general-form“) will do the deal and only go up to the wrapper of the input and error in your case.
Always make sure your id’s are unique.
Just add required> attribute and add this js
$("#formid").validate();
I write this html code with mojolicius code mixed. The idea is to submit the form when I select a radio input that is stylized as a Bootstrap button.
If I put a submit type input, I select the Bootstrap button and I submit it, it works perfectly. But when I use this function (submitForm(node)) to submit the form, it seems to submit it, but is doesn't do anything. The Firefox debugger doesn't throw any error.
<form method="post" id="runform">
%if (keys %$base) {
%for my $option (sort keys %$base) {
<div class="col-sm-4">
<div class="panel panel-success machine">
...
<div class="btn-group pannel-body" data-toggle="buttons">
<label class="btn btn-success" id="base_action" onclick="submitForm(<%= $option %>)">
<input name="id_base" id="submit<%= $option %>" type="radio" value="<%= $option %>"><strong> <i class="fa fa-play" aria-hidden="true"></i> Start this Machine</strong>
</label>
</div>
</div>
</div>
%}
</form>
The JavaScript Function:
function submitForm(node) {
var id = "submit"+ node ;
document.getElementById(id).checked=true;
document.getElementById("runform").submit();
}
Thanks
You lack an action attribute on the form, so it gets submitted to the current page, that's why it seems to submit, but does nothing, because it's likely you have configured your server to just reply with the same page to the request.
Point the form to the right URL.
I have a problem with my input fields in my modal view.
When I take a change in the input fields then it is updating the table list but when I leave the page and go back to this page with the table list then die changes are disappeared.
This is my modal view:
<form class="form-horizontal" name="editForm" novalidate>
<div class="modal-body">
<div class="form-group-sm has-feedback">
<label class="control-label">Firstname</label>
<input type="text"
class="form-control"
name="Fname"
ng-model="selected.fname"
ng-model-options="{updateOn: 'updateItem'}"
ng-required="true"
/>
</div>
</div>
//the same input field for lastname
...
<div class="modal-footer">
<button class="btn btn-default" ng-click="createItem(selected)" type="submit">Erstellen</button>
<button class="btn btn-default" ng-click="updateItem(selected)"> Ändern</button>
<button class="btn btn-default" ng-click="cancel()">Abbrechen</button>
</div>
</form>
Modal Ctrl:
$scope.cancel = function () {
$scope.editForm.$rollbackViewValue();
$modalInstance.dismiss('cancel');
}
$scope.updateItem = function (updateItem) {
CrudService.update(updateItem);
$scope.ok();
}
Crud Service:
...
update: function (updateItem) {
updateItem.$update();
},
...
I have only seen examples of $rollbackViewValue() with one input field and the code: $scope.myForm.inputName.$rollbackViewValue() but I have more than one input fields?
you should call $rollbackViewValue() through the form name:
editForm.$rollbackViewValue()
call it in your template:
{{editForm.$rollbackViewValue.toString()}}
and you will see how it actually works:
function () {
forEach(controls, function(control) {
control.$rollbackViewValue();
});
}
A little late but for others reference (I came across this looking for another issue with $rollbackViewValue).
Using $rollbackViewValue in controller: to use $scope to reference the form from the controller, you have to use the ng-form attribute on a child element of the form (like for instance the form-group div in your example).
That makes $scope.editForm.$rollbackViewValue() available in the controller and resets the entire form.
For cases where buttons are inside the form, using ng-submit and ng-model-options="{ updateOn: 'submit' }" on input fields, then adding 'type=button' attribute to cancel button element (so submit isn't triggered) is a quick solution.
Example:
https://embed.plnkr.co/IQ4vvutC3tcHvVBH0821/
At a user registration web form I validate via ajax whether a username already exists in DB. When a username already exists, the corresponding input-text will go .has-error class.
Edit
I changed the ng-class attribute to {'has-error':signup.userUnavaliable()} but even though that the input is not seemly getting such class, in other words the mail input text is not getting red.
I place the directive at the wrapper as this is how the Bootstrap docs tell it.
This is how my form looks like now:
<form class="form-inline" role="form">
<div class="form-group" ng-class="{'has-error':signup.userUnavaliable()}">
<input type="email" class="form-control input-lg" ng-model="signup.mail" placeholder="e-mail" ng-change="signup.userExists(signup.mail)">
</div>
<div class="form-group">
<input type="password" class="form-control input-lg" placeholder="Contraseña" ng-nodel="signup.password">
</div>
<div class="checkbox">
<label>
<input type="checkbox" ng-model="signup.role" value="admin"> Administrador
</label>
</div>
<button type="submit" class="btn btn-primary" ng-disabled="signup.unavaliable">Registrar</button>
</form>
And this is my Controller:
app.controller('SignUpController',function ($scope, $http) {
$scope.userUnavaliable = function() {
return $scope.unavaliable
}
$scope.print = function(msg) {
console.log(msg)
}
this.userExists = function(mail) {
if (mail) {
var who = $http.get("/existingUsers/"+mail)
who.success(function(data,status, headers, config) {
if (data.mail) {
$scope.unavaliable = true
console.log(data.mail + " ya existe en la DB")
}
else{
$scope.unavaliable = false
}
});
who.error(function(data, status, headers, config) {
alert("AJAX failed!");
})
}
}
})
Also, I'm trying to disable the button and it's not gettin such effect, so I think my controller has any issue.
As given in bootstrap validation states, if you want your label color to be changed according to the validation state of the input, you will have to apply ng-class on that.
Here is the sample code that I had written a little while. Please note that to take advantage of Angular JS validation states on form elements, you need to provide name to all input types.
This code would turn the input box plus label color red or green depending upon the validation state.
<div class="form-group"
ng-class="( newProfileForm.email.$dirty ? (newProfileForm.email.$valid ? 'has-success has-feedback' : 'has-error has-feedback' ) : ' ')"
>
<label class="col-sm-4 control-label">Email</label>
<div class="col-sm-6">
<input type="email" name="email" class="form-control" ng-model="user.mail" ng-required='true'>
<!-- Invalid Span -->
<span ng-if='newProfileForm.email.$invalid && newProfileForm.email.$dirty' class="glyphicon glyphicon-remove form-control-feedback"></span>
<!-- Valid Span -->
<span ng-if='newProfileForm.email.$valid' class="glyphicon glyphicon-ok form-control-feedback"></span>
<p ng-show="newProfileForm.email.$invalid && newProfileForm.email.$dirty" class="bg-danger pad">Please enter valid email.</p>
</div>
</div>
[EDIT] Explanation for name attribute.
Angular makes use of name attribute to determine the state of the input control. So, if you have a input control with name username. Even your form should have a name for angular validation states.
AngularJS would use the fallowing variables to check its validation state.
formname.username.$valid = if username is alright according to validation rules.
formname.username.$invalid = if username is invalid
formname.username.$dirty = if user has edited the input box
formname.username.$pristine = if user has not edited the input box.
Angular makes use of name attribute for validaiton.
And if you want your button to be disabled depending upon the availability of the user.
Use something like
<button class="btn btn-default" ng-disabled="unavaliable">Submit</button>
try
<div class="form-group" ng-class="{'has-error':signup.userUnavaliable()}">
