I have an application with add friend feature, in that feature, user must fill their friend's username in the textbox. this is the html code:
<div content-for="title">
<span>Add Friend</span>
</div>
<form class="form-inline" role="form">
<div class="form-group">
<label class="sr-only" for="exampleInputEmail2">User ID</label>
<input type="text" class="form-control" data-ng-model="add.email" id="exampleInputEmail2" placeholder="User ID">
</div>
<button type="submit" class="btn btn-default" data-ng-click="addfriends()">Add</button>
the interface will be like this
and this is the js code:
// addfriend
$scope.add = {};
$scope.addfriends = function(){
$scope.messages = {
email : $scope.add.email,
userid : $scope.datauser['data']['_id']
};
//event add friend
socket.emit('addfriend',$scope.messages,function(callback){
if(!callback['error']){
$scope.datauser['data']['penddingrequest'].push(callback['data']);
//push pendding request to localstorage user
localStorageService.remove('user');
localStorageService.add('user', $scope.datauser);
$scope.add['email'] = '';
alert('Successfully added friend');
}else{
var msg = callback['error'];
navigator.notification.alert(msg,'','Error Report','Ok');
}
});
};
I want to change this feature little bit, I want to make this textbox showing some suggestion based on the input, like if user input 'a', the textbox will show all user id that start with 'a'. something like twitter's searchbox or instagram searchbox. these user ids is from database.
example searchbox of web instagram
my question is how to change this textbox to be autocomplete but still work like before? thanks very much
There are many ways to do this.
First is this one: You basically create Angular directive for your input.
http://jsfiddle.net/sebmade/swfjT/
Another way to do is to attach onKeyUp event to your input:
<div class="form-group">
<label class="sr-only" for="exampleInputEmail2">User ID</label>
<input type="text" class="form-control" data-ng-model="add.email" id="exampleInputEmail2" placeholder="User ID" ng-keyup="searchFriends()">
<div ng-model="searchFriendsResult" />
</div>
And then, in your controller, you create a searchFriends function that will:
Search your database
Display the result in the view.
Something like this (not a complete code):
$scope.searchFriends = function(value){
// Make Ajax call
var userRes = $resource('/user/:username', {username: '#username'});
userRes.get({username:value})
.$promise.then(function(users) {
$scope.searchFriendsResult = users;
});
};
Use Bootstrap Typeahead
<input type="text" ng-model="asyncSelected"
placeholder="Locations loaded via $http"
uib-typeahead="address for address in getLocation($viewValue)"
typeahead-loading="loadingLocations"
typeahead-no-results="noResults"
class="form-control"/>

I am trying to handle some JavaScript work, which I don't have much experience with. I have a 2 part form where a user enters their personal info, and then company info. I am trying to set some of the company fields to what they already entered in their personal info.
I don't want the user to have to retype address, email, etc.
for example, I have...
<div class="form-group">
<label for="email">Email<span>*</span></label>
<input name="email" type="text" class="form-control required" id="email"placeholder="Email" value=".
{{email}}">
<span id="span_email" class="error-msg"></span>
And...
<div class="form-group">
<label for="comp_email">Company Email<span>*</span></label>
<input name="comp_email" type="text" class="form-control required" id="comp_email"placeholder="Email"
value="{{comp_email}}">
<span id="span_email" class="error-msg"></span>
How would I be able to set that second comp_email field to initially have the email info, so the user doesn't have to retype, unless they actually wanted to change the comp_email to another email address?
EDIT
It is all in one form, just separated by divs. Initially, when the page is loaded, the account section div is displayed, when the user hits next, it triggers the display of the business info.
<input type="button" onclick="nextFormPage(); window.scrollTo(0, 100)"
class="btn btn-danger btn-block" value="Next">
The nextFormPage() function just hides the first div and displays the second div.
You have tagged both javascript and jQuery so I'm not sure which you are using. But you can do this with a single line either way:
Javascript::
document.getElementById("comp_email").value = document.getElementById("email").value;
document.getElementById("email").value gets the value from the email input and we set the value of the document.getElementById("comp_email") by setting its value attribute:
jQuery:
$("#comp_email").val( $("#email").val() );
$("#email").val() get the value from the email input and $("#comp_email").val( ... ); sets the text passed in as the input value.
Javascript Working Example
function nextFormPage(){
document.getElementById("comp_email").value = document.getElementById("email").value;
}
<div class="form-group">
<label for="email">Email<span>*</span></label>
<input name="email" type="text" class="form-control required" id="email" placeholder="Email" value="">
<span id="span_email" class="error-msg"></span>
<div class="form-group">
<label for="comp_email">Company Email<span>*</span></label>
<input name="comp_email" type="text" class="form-control required" id="comp_email" placeholder="Email"
value="">
<span id="span_email" class="error-msg"></span>
<input type="button" onclick="nextFormPage(); window.scrollTo(0, 100)"
class="btn btn-danger btn-block" value="Next">
If your user is logged in, you should pass all of their information to the form, including their email. For example:
const logIn = () => {
... some code to get the user ...
... pass the user to the form, probably through an event listener...
let button = document.createElement("button")
button.textContent = "Edit"
button.addEventListener('click', () => {editYourStuff(user)}
}
const editYourStuff = user => {
... grab whatever your form is called ...
editForm.email.value = user.email
}
This should pre populate your form with the email
I have a form, let's call it myForm similar to this:
<form name="myForm" class="vertical grid-block shrink" ng-init="initSearch()" ng-submit="doSearch(myForm.$valid)" novalidate>
And three input fields: one with keeps details, second which is a starting date and third which is a ending date.
The fields look like this:
<input id="details" type="text" ng-model="myObject.details" placeholder="DETAILS_PLACEHOLDER">
<input id="from" class="uppercase" type="text" name="from" placeholder="{{datePlaceHolder}}" ng-model="myObject.from" required/>
<input id="until" class="uppercase" type="text" name="until" placeholder="{{datePlaceHolder}}" ng-model="myObject.until"/>
And I want to display a button based on the form fields. If the form fields have not changed the button should be hidden.
I tried using $dirty but the problem is $dirty remains true even if the user types in details and then deletes the text.
Anyone has any solution for this?
Also the solution must work even if I come back to the form from another page which probably has another controller.
Any help is appreciated. Thank you
This should fix that. It checks for $pristine, ie untouched.
<button ng-show="myForm.$pristine"></button>
Take a look at sample below, basically you need $viewValue for displaying/hiding submit button.
var app = angular.module('app', []);
app.controller('ctrl', function($scope) {
$scope.myObject = {};
$scope.datePlaceHolder = 'from date';
$scope.datePlaceHolder2 = 'until date';
$scope.doSearch = function() {
alert('submit');
}
$scope.initSearch = function() {
console.log('init search called');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.0/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<p>Need to fill FROM and UNTIL values to submit</p>
<form name="myForm" ng-init="initSearch()" ng-submit="doSearch(myForm.$valid)" novalidate>
<input id="details" type="text" ng-model="myObject.details" placeholder="DETAILS_PLACEHOLDER">
<input id="from" type="text" name="from" placeholder="{{datePlaceHolder}}" ng-model="myObject.from" required/>
<input id="until" type="text" name="until" placeholder="{{datePlaceHolder2}}" ng-model="myObject.until" />
<button type="submit" ng-show="myForm.from.$viewValue && myForm.until.$viewValue">Submit</button>
</form>
</div>
You can add more conditions to
ng-show="myForm.from.$viewValue && myForm.until.$viewValue"
Notice that if you delete value from input, submit button disappears
I'm trying to use Angular's built-in form functions, specifically setPristine() to clear the form on user submit. My controller has access to $scope.newForm (my form) with all of its methods, but running $scope.newForm.$setPristine() isn't resetting the form fields.
Here is my HTML:
<div ng-controller="NewFormController">
<h3>New Entry</h3>
<form name="newForm" method="post" novalidate>
<div class="input-group">
<label>Name</label>
<input name="name" type="text" ng-model="place.name"/>
</div>
<div class="input-group">
<label>Description</label>
<textarea name="description" type="text" ng-model="place.description"></textarea>
</div>
<div class="input-group">
<label>Neighborhood</label>
<input name="neighborhood" type="text" ng-model="place.neighborhood"/>
</div>
<div class="input-group">
<label>Address</label>
<input name="location" type="text" ng-model="place.address"/>
</div>
<input type="submit" value="Submit" ng-click="submit(place)"/>
</form>
</div>
And here is the controller where I call setPristine():
app.controller('NewFormController', function($scope, $compile) {
$scope.place = {
name: 'ExamplePlace',
description: 'This is a description!',
neighborhood: 'Manhattan',
address: '112 Street Place'
};
$scope.submit = function(place) {
$scope.newForm.$setPristine();
$scope.newForm.$setUntouched();
};
});
Here is a working codepen that reproduces my problem.
Note: I'm using Angular version 1.4.3.
$setPristine only marks the form as being $pristine, which is useful for validation-driven expressions and CSS (e.g. .ng-dirty)
So, $setPristine does not clear the form's controls. In fact, it wouldn't even know how to do that. Consider, that to "clear" could mean different things to different models. "Clear" could mean "", or undefined, or null, or anything at all that a custom input control that works with ngModel could mean.
So, to properly clear the form is to modify the View Model that drives the form to whatever definition of "clear" it needs. In most cases - yours included - it is just a matter of setting the View Model to a new object:
$scope.submit = function(place) {
$scope.newForm.$setPristine();
$scope.newForm.$setUntouched();
// clear the form
$scope.place = {};
};
var name = document.getElementById('contact-name'),
email = document.getElementById('contact-email'),
phone = document.getElementById('contact-phone'),
message = document.getElementById('contact-message');
function checkForm() {
if (name.value == '') {
alert('test');
}
}
I was simply trying to make sure everything was working before I began learning actual client-side validation.
Here is the HTML
<form role='form' name='contactForm' action='#' method="POST" id='contact-form'>
<div class="form-group">
<label for="contact-name">First and Last Name</label>
<input type="text" class="form-control" id="contact-name" name="contactName" placeholder="Enter your name.." pattern="[A-Za-z]+\s[A-Za-z]+">
</div>
<div class="form-group">
<label for="contact-email">Email address</label>
<input type="email" class="form-control" id="contactEmail" name="contactEmail" placeholder="Enter Email" required>
</div>
<div class="form-group">
<label for="contact-phone">Phone Number</label>
<input type="number" class="form-control" id="contactPhone" name="contactPhone" placeholder="Enter Phone Number" required'>
</div>
<div class="form-group">
<label for='contactMessage'>Your Message</label>
<textarea class="form-control" rows="5" placeholder="Enter a brief message" name='contactMessage' id='contact-message' required></textarea>
</div>
<input type="submit" class="btn btn-default" value='Submit' onclick='checkForm()'>
</fieldset>
</form>
I took the required attribute off, and if I leave the name field empty it goes right to the other one when i click submit. To check whether javascript was working at all, i did an basic onclick function that worked.
Maybe someone can explain to me what is wrong with the checkForm function. Thanks in advance.
P.S The form-group and form-control classes belong to bootstrap
Change your javascript to this:
var contactName = document.getElementById('contact-name'),
email = document.getElementById('contact-email'),
phone = document.getElementById('contact-phone'),
message = document.getElementById('contact-message');
function checkForm() {
if (contactName.value === '') {
alert('test');
}
}
Okay, Hobbes, thank you for editing your question, now I can understand your problem.
Your code faces three two issues.
Your control flow. If you want to validate your field, you have to obtain its value upon validation. You instead populate variable name when the page loads, but the user will enter the text only after that. Hence you need to add var someVariableName = document.getElementById(...); to the beginning of the checkForm() function.
global variables. Please do not use them like that, it is a good design to avoid global variables as much as possible, otherwise you bring upon yourself the danger of introducing side effects (or suffering their impact, which happens in your situation). The global context window already contains a variable name and you cannot override that. See window.name in your console. You can of course use var name = ... inside the function or a block.
Even if you fix the above, you will still submit the form. You can prevent the form submission if you end your checkForm() function with return false;
For clarity I append the partial javascript that should work for you:
function checkForm() {
var name = document.getElementById('contact-name');
if (name.value == '') {
alert('test');
return false;
}
}
EDIT: As Eman Z pointed out, the part 1 of the problem does not really prevent the code from working as there's being retrieved an address of an object (thanks, Eman Z!),
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()}">
