AngularJS dynamic forms with ng-repeat - javascript

i am working with AngularJS dynamic forms . According to my userid value i generated multiple form field with same model name using ng-repeat. i am not able to get this input model values due to this ng-repeat. in this example i am using static userid data.
<div ng-app="myApp">
<div ng-controller="myCtrl">
<form role="form" name='userForm' novalidate>
<div class="container">
<div class="row" ng-repeat="myid in userid">
<div class="form-group">
<div class="col-md-3">
<label>ID</label>
<input ng-model="myid" id="myid" name="myid" placeholder="Enter bugid" type="text" required readonly disabled>
</div>
<div class="col-md-3">
<label>Comments</label>
<textarea ng-model="manualComment" id="textarea1" rows="1" required></textarea>
</div>
<div class="col-md-3 ">
<label>Gender</label>
<select ng-model="gender" name="select2" required>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
</div>
</div>
</div>
</div>
<div class="buttonContainer text-center btn-container">
<br>
<button ng-disabled="userForm.$invalid" type="button" id="adduser" ng-click="adduser">Add user</button>
<button type="button" class="btn button--default btn--small pull-center">Close</button>
</div>
</form>
</div>
my js code
var myApp = angular.module('myApp', []);
myApp.controller('myCtrl', function($scope) {
$scope.userid = [1, 2, 3];
$sope.adduser = function() {
}
});
i need to send array of objects to my server.my userid also dynamic it has more than 100 data. how can i get each and every data field model value? and how to convert those model data into array of objects like my sampleserver data?
i am expecting my final output data like this
var sampleServerData = [{
"userid": 1,
"manualcomment": "mycmt1",
"gender": "male"
}, {
"userid": 2,
"manualcomment": "mycmt2",
"gender": "male"
}, {
"userid": 3,
"manualcomment": "mycmt3",
"gender": "female"
}]

You should change your textarea id to a class or create a textarea id in your user object(more on that below).
If the id's you have to work with are in an array, then create an array of objects based on you ids array.
var ids = [1, 2, 3];
var users = ids.map(function(id) {
return {id: id, comment: "", gender: ""};
})
I think I have a solution for you, I made you a jsbin. Make sure you hit the run with js button, for some reason it doesn't run onload.
HTML
<div ng-app="myApp">
<div ng-controller="myCtrl">
<form role="form" name='userForm' novalidate>
<div class="container">
<div class="row" ng-repeat="user in users">
<div class="form-group">
<div class="col-md-3">
<label>ID</label>
<input ng-model="user.id" id="user.id" name="user.id" placeholder="Enter bugid" type="text" required readonly disabled>
</div>
<div class="col-md-3">
<label>Comments</label>
<textarea ng-model="user.comment" id="textarea1" rows="1" required></textarea>
</div>
<div class="col-md-3 ">
<label>Gender</label>
<select ng-model="user.gender" name="select2" required>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
</div>
</div>
</div>
</div>
<div class="buttonContainer text-center btn-container">
<br>
<button ng-disabled="userForm.$invalid" type="button" id="adduser" ng-click="adduser()">Add user</button>
<button type="button" class="btn button--default btn--small pull-center">Close</button>
</div>
</form>
</div>
JS
var myApp = angular.module('myApp', []);
myApp.controller('myCtrl', function($scope) {
$scope.ids = [1, 2, 3];
$scope.users = $scope.ids.map(function(id) {
return {id: id, comment: "", gender: ""};
});
$scope.adduser = function() {
var data = $scope.users.map(function(user) {
return {
"userid": user.id,
"manualcomment": user.comment,
"gender": user.gender
}
});
console.log("data", data)
}
});

In your HTML file you can call ng-repeat like this;
<div ng-app="myApp">
<div ng-controller="myCtrl">
<form role="form" name='userForm' novalidate>
<div class="container">
<div class="row" ng-repeat="myid in userId">
<div class="form-group">
<div class="col-md-3">
<label>ID</label>
<input ng-model="userId[$index].id" id="myid"name="myid" placeholder="Enter bugid" type="text" required readonly disabled>
</div>
<div class="col-md-3">
<label>Comments</label>
<textarea ng-model="userId[$index].manualcomment" id="textarea1" rows="1" required></textarea>
</div>
<div class="col-md-3 ">
<label>Gender</label>
<select ng-model="userId[$index].gender" name="select2" required>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
</div>
</div>
</div>
</div>
<div class="buttonContainer text-center btn-container">
<br>
<button ng-disabled="userForm.$invalid" type="button" id="adduser" ng-click="addusers()">Add user</button>
<button type="button" class="btn button--default btn--small pull-center">Close</button>
</div>
</form>
</div>
And then in the controller.
var myApp = angular.module('myApp', []);
myApp.controller('myCtrl', function($scope) {
$scope.userId = [1,2,3,4,5] // or new Array(3);
$sope.adduser = function() {
var serverData = $scope.userId;
}
});

you can use track by $index in ng-repat and then use the index for models
<div class="row" ng-repeat="myid in userid track by $index">
<div class="form-group">
<div class="col-md-3">
<label>ID</label>
<input ng-model="userId[$index].id" id="myid"name="myid" placeholder="Enter bugid" type="text" required readonly disabled>
</div>
<div class="col-md-3">
<label>Comments</label>
<textarea ng-model="userId[$index].manualcomment" id="textarea1" rows="1" required></textarea>
</div>
<div class="col-md-3 ">
<label>Gender</label>
<select ng-model="userId[$index].gender" name="select2" required>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
</div>

Get textarea value from selected input by data id, from appended (jquery) elements

I was able to get the value for Description (textarea) from the first service (selected input) (which is right), for the attribute of data id, but I'm having a problem getting it from appended elements, after using the add more button
What am I missing, please?
Below is my code and I can explain further if need be.
<div class="service-box">
<div class="row">
<div class="col-md-12 service-group">
<div class="row">
<div class="form-group mb-3 col-md-6">
<label class="form-label">Service</label>
<div >
<select type="text" class="form-select" placeholder="Services" value="" name="service" id="service">
<option value="" disabled selected>Select your option</option>
#foreach ($services as $service)
<option value="{{$service->service_name}}" data-id="{{$service->description}}">{{$service->service_name}}</option>
#endforeach
</select>
</div>
</div>
<div class="form-group mb-3 col-md-6">
<label class="form-label">Amount</label>
<div >
<input type="text" class="form-control" name="amount" id="amount" placeholder="Amount">
</div>
</div>
<div class="form-group mb-3 col-md-12">
<label class="form-label">Description</label>
<textarea class="form-control" id="description" name="description" rows="6" placeholder="Content.." readonly></textarea>
</div>
</div>
</div>
</div>
</div>
<div class="col-md-12">
<button type="button" id="addmore" class="btn btn-default">Add more</button>
<button type="button" id="remove" class="btn btn-default">Remove</button>
</div>
$("#addmore").click(function() {
var serviceGroupHTML = $('.service-group').html();
$( ".service-box" ).append(serviceGroupHTML);
});
$("#remove").on("click", function() {
$(".service-box").children().last().remove();
});
<!-- This is where the problem lies -->
const service = new Array(document.getElementById("service"));
const description = new Array(document.getElementById("description"));
service[0].addEventListener("change", function(){
description[0].value = $('#service option:selected').data('id');
})
service[1].addEventListener("change", function(){
description[1].value = $('#service option:selected').data('id');
})
As your newly created element are dynamic so you need to bind it with static element. Then, you can get the value of the data-attribute by using $(this).find("option:selected").data("id") and assign this to your textarea of that particular group .
Demo Code :
$("#addmore").click(function() {
$('.service-group:first').clone().find("input:text,textarea").val("").end()
.appendTo('.service-box');
});
$("#remove").on("click", function() {
$(".service-box").children().last().remove();
});
$("body").on("change", "select[name=service]", function() {
//get description for data-attribute
var description = $(this).find("option:selected").data("id");
//assign value
$(this).closest(".service-group").find("textarea[name=description]").val(description)
})

get value from form select and then calculate value in an input

I am trying to calculate multiple values based on multiple selections from a and then have the data add up and display in an on the same form. I tried some jquery stuff but didn't really work at all. I've tried using some Javascript to do the calcultions but nothing seems to be happening.

To clarify, I want {{ $law->months }} & {{ $law->fine }} to add up and then display in #punishment <input>
Thanks for looking!
You can do some thing like this.
Update <option> tag to this
<option data-fine="{{$law['fine']}}" data-months="{{$law['months']}}" value="{{ $law['name'] }} {{ $law['fine'] }} {{ $law['months'] }}">Offence: {{ $law['name'] }} </option>
and you can get data attribute of the selected <option> tag in your script like this.
`$("#lawspicker").change(function() {
var fine = $(this).find(':selected').data('fine');
let months = $(this).find(':selected').data('months');
$("#punishment").val(parseInt(fine+months));
});`
Thanks.
I would be tempted to replace your select element with checkboxes personally.
An example below using jquery to calculate the fine and months when a button is clicked but could be an event of your choosing. I stripped it back from your example so it was easier to see what is going on.
Checkbox example
<div class="container mt-4">
<div class="row">
<div class="col-12">
<div class="form-group">
<h4>Select Offences</h4>
<div class="d-flex">
<div class="custom-control custom-checkbox">
<input type="checkbox" name="laws[]" id="law-a" data-fine="100" data-months="12" class="custom-control-input offence">
<label for="law-a" class="custom-control-label">Law A</label>
</div>
<div class="custom-control custom-checkbox">
<input type="checkbox" name="laws[]" id="law-b" data-fine="999" data-months="6.5" class="custom-control-input offence">
<label for="law-b" class="custom-control-label">Law B</label>
</div>
<div class="custom-control custom-checkbox">
<input type="checkbox" name="laws[]" id="law-c" data-fine="123.5" data-months="8" class="custom-control-input offence">
<label for="law-c" class="custom-control-label">Law C</label>
</div>
</div>
</div>
</div>
<div class="col-12">
<div class="form-group">
<label for="punishment">Punishment</label>
<input type="text" class="form-control" id="punishment" name="punishment" readonly>
</div>
</div>
<div class="col-12">
<button type="submit" id="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</div>
Then some javascript (jquery)
$(function() {
$("#submit").click(function() {
let fine = 0;
let months = 0;
$(".offence").each(function(index, obj) {
if (obj.checked) {
fine += parseFloat($(obj).data("fine"));
months += parseFloat($(obj).data("months"));
}
})
$("#punishment").val("Fine: "+ fine + " Months: " + months);
})
});
When you click submit, the javascript will loop through each element with the offence class and then read the value of the data-fine and calculate the totals.

Initialize select on your angular add function.
$scope.choices = [{id: 1,purchaser_account:'',price:0,weight:0}];
$scope.addNewChoice = function() {
var newItemNo = $scope.choices.length+1;
$scope.choices.push({'id':newItemNo,purchaser_account:'',price:0,weight:0});
$(".select2").select2();
};
same initialize it where your are add first option in choice array.

I am trying to fetch values of contact numbers i.e with id's relationship-type-contact(n) values in the line "
var relationshipContactNumber =$this.find("input[type=text]:last-child").val();"
This is fetching values of first-child textboxes in the variable relationshipContactNumber in the loop.
Please help !!!
This should work, use the .first() and .last() selectors.
Another way, if you have access to alter the HTML, is to add class names for the input fields and select them by using that instead.
function getData() {
var relationship_details_array = [];
// Relationship details Array
$(".relationship-container").each(function(i, obj) {
var $this = $(this);
$this.find("select").each(function() {
var relationshipTypeValue = $(this).val();
var relationshipName = $this.find("input[type=text]").first().val();
var relationshipContactNumber = $this.find("input[type=text]").last().val();
var innerRelationshipArray = {};
innerRelationshipArray = {
relationshipTypeValue: relationshipTypeValue,
relationshipName: relationshipName,
relationshipContactNumber: relationshipContactNumber
};
relationship_details_array.push(innerRelationshipArray);
});
});
console.log(relationship_details_array);
}
$("#getData").on("click", getData);

I have created dynamic forms with ng-repeat directive. I am getting form field according to userid value. Once I have filled every field in form my add user button should be enabled. As of now its not enabled. I have attached my code below.
My html code:
<div ng-app="myApp">
<div ng-controller="myCtrl">
<form role="form" name='userForm' novalidate>
<div class="container">
<div class="row" ng-repeat="myid in userid">
<div class="form-group">
<div class="col-md-3">
<label>ID</label>
<input ng-model="myid" id="myid" name="myid" placeholder="Enter bugid" type="text" required readonly disabled>
</div>
<div class="col-md-3">
<label>Comments</label>
<textarea ng-model="manualComment" id="textarea1" rows="1"></textarea>
</div>
<div class="col-md-3 ">
<label>Gender</label>
<select ng-model="gender" name="select2">
<option value="male">Male</option>
<option value="female">Female</option>
</select>
</div>
</div>
</div>
</div>
<div class="buttonContainer text-center btn-container">
<br>
<button ng-disabled="!(myid && manualComment && gender)" type="button" id="adduser">Add user</button>
<button type="button" class="btn button--default btn--small pull-center">Close</button>
</div>
</form>
</div>
my app.js file
var myApp = angular.module('myApp', []);
myApp.controller('myCtrl', function($scope) {
$scope.userid = [1, 2, 3]
});
How can I enable add user button once all field are filled?
Update:
If you want to convert your initial array from the server to a usage array check this fiddle

If you want an object which contains all the form values, please refer to the below fiddle!

Based on the statement below, this is my solution.
How can I enable add user button once all field are filled?
I have added the required attribute to all the input fields, the form name userForm is a variable in the scope. It has its validation variables, in my case I am using userForm.$invalid which will be true unless all the fields with required attribute are filled. The Add User is disabled by using the ng-disabled attribute, check the below JSFiddle for a demo.
