I am new to Angular and I am trying to build a search page, I have a button that executes a function to get data from the server when it is clicked. The data is returned to the client, now I want to be able to display the data on that same page.
I've tried something but it does not show. What am I doing wrong?
This is my html:
<div class="search-area col-md-12 no-padding" ng-controller="SearchController as search">
<div class="col-md-3">
<!-- Select Basic -->
<div class="form-group">
<div class="col-md-12">
<select id="From" name="From" ng-model="d.from" class="form-control"
ng-options="item.id as item.dest_name for item in d.destinations">
</select>
</div>
</div>
</div>
<div class="col-md-3">
<!-- Select Basic -->
<div class="form-group">
<div class="col-md-12">
<select id="To" name="To" ng-model="d.to" class="form-control"
ng-options="item.id as item.dest_name for item in d.destinations">
</select>
</div>
</div>
</div>
<div class="col-md-3">
<div class="form-group">
<div class="col-md-12">
<input id="When" name="When" ng-model="d.when" placeholder="When" class="form-control input-md" required="" data-provide="datepicker" data-date-format="mm/dd/yyyy">
</div>
</div>
</div>
<div class="col-md-3">
<a ng-click="getSchedules()" class="submit">Buy Ticket</a>
</div>
</div>
<div class="clear"></div>
<div class="col-md-12" ng-repeat="schedule in d.schedules">
<div class="form-group">
<div class="col-md-12" ng-show="schedule.length">
<% schedule.transport_entity %>
</div>
</div>
</div>
search.js
(function() {
var app = angular.module('search', []);
app.controller('SearchController', ['$http', '$scope', function($http, $scope) {
var search = this;
this.destinations = [];
$scope.d = {};
$scope.getSchedules = function() {
$http.get('/trips/schedules?from='+$scope.d.from+'&to='+$scope.d.to+'&when='+$scope.d.when).success(function(data) {
$scope.d.schedules = data; // Getting The Search Results Here
});
};
$http.get('/trips/destinations').success(function(data) {
$scope.d.destinations = data;
});
}]);
}) ();
Store your data in the $scope rather than in properties of the controller itself. Also you can simplify your logic considerably by making proper use of data binding - if you set an ng-model on the form controls and use ng-options for the select boxes then you don't need any of the jQuery logic to extract values from the fields and generate the option elements - angular will do it all for you.
<div class="search-area col-md-12 no-padding" ng-controller="SearchController as search">
<div class="col-md-3">
<!-- Select Basic -->
<div class="form-group">
<div class="col-md-12">
<select id="From" name="From" ng-model="data.from" class="form-control" ng-options="item.id as item.dest_name for item in data.destinations">
</select>
</div>
</div>
</div>
<div class="col-md-3">
<!-- Select Basic -->
<div class="form-group">
<div class="col-md-12">
<select id="To" name="To" ng-model="data.to" class="form-control" ng-options="item.id as item.dest_name for item in data.destinations">
</select>
</div>
</div>
</div>
<div class="col-md-3">
<div class="form-group">
<div class="col-md-12">
<input id="When" name="When" ng-model="data.when" placeholder="When" class="form-control input-md" required="" data-provide="datepicker" data-date-format="mm/dd/yyyy">
</div>
</div>
</div>
<div class="col-md-3">
<a ng-click="getSchedules()" class="submit">Buy Ticket</a>
</div>
</div>
<div class="clear"></div>
<div class="col-md-12" ng-repeat="schedule in data.schedules">
<div class="form-group">
<div class="col-md-12" ng-show="schedule.length">
<% schedule.transport_entity %>
</div>
</div>
</div>
search.js
(function() {
var app = angular.module('search', []);
app.controller('SearchController', ['$http', '$scope' function($http, $scope) {
$scope.data = {};
$scope.getSchedules = function() {
$http.get('/trips/schedules?from='+$scope.data.from+'&to='+$scope.data.to+'&when='+$scope.data.when)
.success(function(data) {
$scope.data.schedules = data; // Getting The Search Results Here
});
};
$http.get('/trips/destinations').success(function(data) {
$scope.data.destinations = data;
});
}]);
}) ();
You need to add it to the scope.
$scope.search = this;
And when storing the results of the search..
$scope.search.schedules = data;
Then it will be available in the view.

I have a form and trying to send the value of the input to the angular controller but on click, the value in the controller is showing undefined.
html code
<div ng-if="questioncode == 2" class="user-form">
<div class="row">
<form>
<div class="col-sm-12">
<label class="control-label" >Phone number</label>
</div>
<div class="col-sm-12">
<input type="text" class="form-control" name="phone" placeholder="your phone number" ng-model="phone">
</div>
<div class="col-sm-12">
<input type="submit" class=" col-sm-12 btn btn-primary" ng-click="submituserPhone();" >
<flash-message duration="3000" show-close="true" on-dismiss="myCallback(flash);" ></flash-message>
</div>
</form>
</div>
</div>
angular controller
$scope.submituserPhone = function() {
console.log($scope.phone);
$http.post('insertphone',$scope.phone),then(function() {
if(response.data.status === false) {
Flash.create('danger',response.data.message);
}else{
$scope.questioncode = 3;
}
})
}
So the problem is the ng-if which is creating a new scope, hence the scope variable phone is not getting updated in the controller. Here are two methods to tackle this problem.
Using $parent:
You can use $parent to update the variable of the parent scope instead of the current one, then your variable will be visible inside the controller.
var app = angular.module('myApp', []);
app.controller('MyController', function MyController($scope) {
$scope.questioncode = 2;
$scope.submituserPhone = function() {
console.log($scope.phone);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-controller='MyController' ng-app="myApp">
<div ng-if="questioncode == 2" class="user-form">
<div class="row">
<form>
<div class="col-sm-12">
<label class="control-label">Phone number</label>
</div>
<div class="col-sm-12">
<input type="text" class="form-control" name="phone" placeholder="your phone number" ng-model="$parent.phone">
</div>
<div class="col-sm-12">
<input type="submit" class=" col-sm-12 btn btn-primary" ng-click="submituserPhone();">
<flash-message duration="3000" show-close="true" on-dismiss="myCallback(flash);"></flash-message>
</div>
</form>
</div>
</div>
</div>
Pass the variable as a parameter:
You can simply just pass the variable of the created scope into the controller function and update it there, as shown below.
var app = angular.module('myApp', []);
app.controller('MyController', function MyController($scope) {
$scope.questioncode = 2;
$scope.submituserPhone = function(phone) {
$scope.phone = phone;
console.log($scope.phone);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-controller='MyController' ng-app="myApp">
<div ng-if="questioncode == 2" class="user-form">
<div class="row">
<form>
<div class="col-sm-12">
<label class="control-label">Phone number</label>
</div>
<div class="col-sm-12">
<input type="text" class="form-control" name="phone" placeholder="your phone number" ng-model="phone">
</div>
<div class="col-sm-12">
<input type="submit" class=" col-sm-12 btn btn-primary" ng-click="submituserPhone(phone);">
<flash-message duration="3000" show-close="true" on-dismiss="myCallback(flash);"></flash-message>
</div>
</form>
</div>
</div>
</div>
I have seen similar questions, but am unable to understand the mistake and the way around.
I have a basic mean stack application. I have a submit button, where if I click, it throws me an error saying in the browser saying :
Cannot POST /
Although, the post request has gone to the server and it gets updated in my database. I just want the browser to come back to the previous page after I click submit and post request is done!
The browser console also shows an error saying:
POST http://localhost:3000/ 404 (Not Found)
Here are my files for reference ctrl1.js:

Your database gets updated because you have attached an ng-click directive to the submit button, which is correctly hitting your /applicationList route with a POST: that's good.
At the same time, your button is inside a form element and is of type submit, which means clicking it will trigger the form action. Because you have left the form action empty - action=" " - you are also hitting the non-existent / route. That's why you get your error.
A simple fix is to change your button types to button so that they don't trigger the form action, and remove the action attribute from the form.
you are trying to get '/' for this plealse write this code in
server.js
app.get('/', function(req, res) {
res.end('Welcome to api');
return;
})

I'm developing multiple security questions in the dropdown and its answers using angular js. The problem is that these questions come from an array inside the controller and on clicking on drop down, all the other dropdowns are also changing and first selected option should not be displayed in the other drop downs.I need to avoid it.I don't know where I'm making the mistake.
ng-model should be different for each select:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.questions = ["Select a question from the following options.", "What is your favorite color?", "What is your favorite sport?", "What is your favorite car?", "What is your first pet name?", "What is your first car color?"];
$scope.model = {};
});

please set different names for different select tags
You cannot use same model for different select tags.
I am trying to develop a page with a total of 6 input fields - 2 constant and 4 dynamic. A single form needs to send data with dynamic marks rows that will be added by users choice.
View :
<body ng-controller="homeController">
<div class="container">
<div class="row">
<div class="col-sm-8">
<h3>Students Form</h3>
<form name="StudentForm">
<div class="row">
<div class="col-sm-6">
<input type="text" ng-model="formData.regno" placeholder="Reg Number">
</div>
<div class="col-sm-6">
<input type="text" ng-model="formData.name" placeholder="Student Name">
</div>
</div>
<div ng-show="showMarks" ng-repeat="formData in studentMarks">
<div class="row">
<br>
<div class="col-sm-3"><input type="text" ng-model="formData.subone"
placeholder="Subject 1" style="width:70%"></div>
<div class="col-sm-3"><input type="text" ng-model="formData.subtwo"

Controller :
var std = angular.module("studentsApp",[]);
std.controller("homeController", function($scope){
$scope.showMarks=false;
$scope.studentMarks=[];
$scope.addMarks = function (){
$scope.showMarks=true;
var rowConut = $scope.studentMarks.length +1;
$scope.studentMarks.push({
subone:0,
subtwo:0,
subthree:0,
subfour:0,
});
console.log(rowConut);
console.log($scope.studentMarks);
};
$scope.delMarks = function (){
rowConut = $scope.studentMarks.length -1;
$scope.studentMarks.pop();
console.log(rowConut);
console.log($scope.studentMarks);
};
$scope.saveFullForm = function(){
//
console.log($scope.formData);
console.log($scope.marks);
console.log($scope.studentMarks);
};
});
Problem is:
When I click -save button form data for dynamic rows does not get shown up
in the console. Also, when adding more than one row, -delete button does
not deletes individual rows. The last row gets deleted by default. What might be the
problem in the code.
When using array.pop, it will remove the last element in the array. The solution is to pass the element index from the view through ng-click and splice the array based on the index , thus the element will be remove out from the array
View
<div class="col-sm-2"><button ng-click="delMarks($index)"> Delete</button></div>
Controller
$scope.delMarks = function (index){
rowConut = $scope.studentMarks.length -1;
$scope.studentMarks.splice(index,1);
console.log(rowConut);
console.log($scope.studentMarks);
};
Update
var std = angular.module("studentsApp",[]);
std.controller("homeController", function($scope){
$scope.showMarks=false;
$scope.studentMarks=[];
$scope.addMarks = function (){
$scope.showMarks=true;
var rowConut = $scope.studentMarks.length +1;
$scope.studentMarks.push({
subone:$scope.formData.regno,
subtwo:0,
subthree:0,
subfour:0,
});
//console.log(rowConut);
//console.log($scope.studentMarks);
};
$scope.delMarks = function (index){
rowConut = $scope.studentMarks.length -1;
$scope.studentMarks.splice(index,1);
//$scope.studentMarks.pop();
//console.log(rowConut);
//console.log($scope.studentMarks);
};
$scope.saveFullForm = function(){
//
console.log($scope.formData);
console.log($scope.marks);
console.log($scope.studentMarks);
};
});

The bug is very weird, I have been stucking here for hours just can find why my function in controller is fired.
Here is my HTML code:
<div class="col-md-9 clearfix" id="customer-account" ng-controller='ProfileController'>
<div class="box clearfix">
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="password_old">oldpassword</label>
<input type="password" class="form-control" id="password_old" ng-model="passwordold">
</div>
</div>
</div>
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="password_1">newpassword</label>
<input type="password" class="form-control" id="password_1" ng-model="passwordnew1">
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label for="password_2">retype</label>
<input type="password" class="form-control" id="password_2"ng-model="passwordnew2">
</div>
</div>
<p>{{passwordnew2}}</p>
</div>
<!-- /.row -->
<div class="text-center">
<button type="submit" class="btn btn-primary">
<i class="fa fa-save" ng-click="changePwd(passwordold,passwordnew1,passwordnew2)"></i> save
</button>
</div>
<div class="text-center" >
<p>{{errorMessageChangepwd}}aaaa</p>
</div>
</div>
</div>
After I click the Button, which ng-click attribute as you can see, nothing happen.
Here is my controller code:
controller('ProfileController', ['$scope','UserFactory','SharedDataFactory',
function($scope,UserFactory,SharedDataFactory){
$scope.user = UserFactory.user;
$scope.passwordold;
$scope.errorMessageChangepwd='error';
$scope.showErrMsgChangepwd = false;
$scope.passwordnew1;
$scope.passwordnew2;
$scope.changePwd = function(passwordold,passwordnew1,passwordnew2){
console.log("aaaaaaaaaa");
if (passwordnew1!==passwordnew2){
$scope.showErrMsgChangepwd= true;
$scope.errorMessageChangepwd = 'error';
}else{
UserFactory.changePwd(passwordnew1)
.catch(function(err){
console.log(err.data);
}).then(function(response){
console.log(response);
});
}
};}]);
I called console.log("aaaaaaaaaa"); in the first line of my function, but after I click the button, nothing is shown on console.
And also
<div class="text-center" >
<p>{{errorMessageChangepwd}}aaaa</p>
</div>`
does not show error aaaa as expected but aaa on the browser.
what could be wrong?
Thanks.
You need to add ng-controller="ProfileController" in the top of your form.
Which looks like missing on your code.
