How to using eq() while dealing in Div tag - Jquery

I am having this following HTML code,
<div class="row add_all">
<div class="col-lg-12">
<span class="pf-title">Title</span>
<div class="pf-field">
<input type="text" placeholder="Write Something here.." />
<button class="add-subject" type="button">
<i class="fa fa-plus"></i>
</button>
<div style="display: inline-flex; margin-bottom: 22px;">
<select data-placeholder="Allow In Search" id="input_data1" style="width: 70%; margin-right: 10px;">
<option value="">Level</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<select data-placeholder="Allow In Search" id="input_data2" style="width: 70%; margin-right: 10px;">
<option value="">Level</option>
<option value="I">I</option>
<option value="II">II</option>
<option value="III">III</option>
</select>
</div>
</div>
</div>
<div class="col-lg-12">
<div class="sodmzs"></div>
</div>
<div class="col-lg-12">
<button type="submit">Update</button>
</div>
</div>
Where I am having one textbox in the first row and two combo boxes in the second row. When the user will click on plus icon, another textbox in the first row and two combo boxes in the second row will get generated and added. User can generate as many as they wants (1 textbox and 2 combo boxes) via clicking on the add icon.
To get the whole values from the generated div tag, I wrote the following code,
$("#form_id_name").submit(function(e){
e.preventDefault();
var json_data = [];
$(".add_all").each(function(){
title = $(this).children().eq(0).find('input').val();
level_no = $(this).children().eq(0).find("option:selected").text();
level_ro = $(this).children().eq(1).find("option:selected").text();
var single_data = {"title":title, "level_no":level_no, "level_ro":level_ro}
json_data.push(single_data);
});
var string_data = JSON.stringify(json_data);
console.log(string_data);
*ajax code*
But this code doesn't help me to get the desired output that I want. Can you help me out to know where I am doing it wrong ?
Thanks.
NOTE: I am appending the HTML code using $('.sodmzs').append(fieldHTML); where fieldHTML contains html code encapsulated in single quotes.

I believe you're using too many methods to access the DOM elements, this code is a simplified version, I tested it in codepen and returns:
$("button").click(function (e) {
e.preventDefault();
var json_data;
$(".add_all").each(function () {
title = $(this).find("input").val();
level_no = $(this).find("option:selected:first").text();
level_ro = $(this).find("option:selected:last").text();
json_data = {
title: title,
level_no: level_no,
level_ro: level_ro
};
});
json_data = JSON.stringify(json_data);
console.log(json_data);
});
// "{'title':'my title','level_no':'1','level_ro':'III'}"

It looks like you're pushing single_data onto json_data before assigning it a value. Due to hoisting, single_data gets declared at the top of the function - so it's defined and you won't get an error. But, you also won't get your data.
Change
json_data.push(single_data);
var single_data = {"title":title, "level_no":level_no, "level_ro":level_ro}
to just
json_data.push({"title":title, "level_no":level_no, "level_ro":level_ro});
Also, you could clean up the code a bit by adding classes to your inputs & selects. So this:
title = $(this).children().eq(0).find('input').val();
could be simplified to this:
title = $(this).find(".titleinput").val();
It'll also be more robust if you change the underlying markup.

Problem with add and delete elements dinamically in angularjs

I have multiple select with different values. When the user selects the options that he wishes, press add button and must be added as elements to an array and that new line of added options be displayed in the view.
This does not work correctly, since each new selection steps on the values of the previous one. Only the last chosen option prevails. Example of my wrong array of values:
[{"product":"Product3","type":"A"},{"product":"Product3","type":"A"},{"type":"Product3","type":"A"}]
Here is my code:
<div class="col-md-3">
<label for="product" class="control-label">Product</label>
<select class="form-control pull-right" name="product" ng-model="data.product" >
<option ng-repeat='(key,value) in productList' value="{{key}}">{{value}}</option>
</select>
</div>
<div class="col-md-3">
<label for="type" class="control-label">Type</label>
<select class="form-control pull-right" name="type" ng-model="data.type" >
<option ng-repeat='i in typeList' value="{{i}}">{{i}}</option>
</select>
</div>
<button type="button" class="btn" ng-click="addElements()" >Add</button>
<div class="col-md-3">{{elementsList}}</div>
And in my angular controller:
$scope.elementsList = [];
$scope.addElements = function() {
$scope.elementsList.push($scope.data);
}
What's my problem? I am new in angular and js and it is difficult for me to see it ... how can I add and remove elements dynamically? Thanks!

When you add the $scope.data object to the array in addElements, it adds a reference to that object because that's how Javascript objects are stored: by reference. What that means is that any time that $scope.data changes in the future, the value you see in the array will also change. So you can do something like this instead:
$scope.addElements = function() {
const clone = Object.assign({}, $scope.data);
$scope.elementsList.push(clone);
}
This creates a new object clone each time.

using ng-options within ng-repeat

I am new to angular and I'm confused over this thing. I'm trying to populate a select box based on object inside an array. I want selectbox by using ng-repeat for that array... but initially i need to show only one selectbox after clicking add() next selectbox has to come. for ref:[initially one selectbox has to come]
HTML
<div class="col-lg-12" id="variant1" style="margin-top:10px" ng-repeat="variant in variants">
<div class="col-lg-4" style="text-align:right;padding-top:2px;padding-right: 20px" >
<label for="variant1name">Variant Name</label>
</div>
<div class="col-lg-6" >
<div >
<select class="form-control" ng-model="filterFormInputs.apps" ng-options="app.Application for app in variants" >
<option value="" disabled selected>Select an Application</option>
</select>
<label ng-repeat="checkbox in filterFormInputs.apps.details">
<input class="ecomtexttype1" type="checkbox" ng-model="checkbox.checked"> {{checkbox.name}}
</label>
</div>
</div>
</div>
Controller:
$scope.variants =
[
{"Application": "Color", "details":[{"name":"red"},{"name":"blue"},{"name":"black"}]},
{"Application": "Color", "details":[{"name":"red"},{"name":"blue"},{"name":"black"}]},
{"Application": "Color", "details":[{"name":"red"},{"name":"blue"},{"name":"black"}]}
]

I think that you can just have your add() function update the array... if things are configured correctly the new row should render due to the binding on the array.
As mentioned in comments you did not provide enough source code, so here is the assumed pseudo-code:
in html you might have
<button ng-click="$scope.add()">Add</button>
so in the controller
$scope.variants = [
// array of whatever you are displaying
{"foo":"bar1"},
{"foo":"bar2"}
];
$scope.add = function() {
variants.push({"foo":"bar_new"});
}
Have you considered using a Directive for this? That may work better, depending on your situation. Look into this: https://docs.angularjs.org/guide/directive

AngularJS: Is there a way to create two-way binding on a label element so that I can dynamically attach it to an object?

This problem has been frustrating me for the last couple days now so, here I am. I'll try to be as clear as possible.
I have an object to retrieve from the database. This object is used to create dropdown menus. It has two properties on it: A section property, which contains one string. The other property is called value, which contains all the possible options that the user can select in the dropdown. I use two nested ng-repeats in my HTML to create the dropdowns.
I am trying to send out to the database a formData object that has 2 properties in it: the name of the dropdown menu, and the value that the user selected. Appending the value selected from the dropdown menu is easy thanks to two way data binding that I set on the select element. However, I CANNOT figure out how to grab the value from the label element inside my controller so that I can attach it to my formData object. As far as I know, ng-model does not work on a label element. Here is the HTML, which hopefully will make it a bit more clear:
<form class="form-horizontal" ng-controller="PreferenceCtrl">
<div ng-repeat="(name, section) in configs">
<label ng-bind="name"></label>
<select class="form-control" ng-model="formData.settings[$index].value">
<option value="" disabled="disabled">---Please Select Option---</option>
<option ng-repeat="item in section" value="{{item.value}}" ng-bind="item.value">
</option>
</select>
</div>
<div class="col-md-12" ng-include="gametemp"></div>
<div class="row">
<div class="hr-line-dashed"></div>
<div class="text-center col-md-12 padding-15">
<button class="btn btn-primary btn-lg" ng-click="saveSetting()" formnovalidate translate>
<i class='fa fa-circle-o-notch fa-spin' ng-if="showBusy"></i> Save
</button>
</div>
</div>
</form>
Because the <select> class can have an ng-model attached to it, I can easily capture that value in my controller. I cannot do the same with the label. If anyone can help me out I will forever be your best friend. Thank you!

In answer to your question title "Is there a way to create a two-way binding on a label element", no, that isn't possible.
But if I understand correctly what you're trying to do, it sounds like you want to save data to the database based on information contained in both the <label> and it's associated <select>. If that's true, then I'd recommend using an ng-change function in your <select> like this:
<select class="form-control" ng-model="formData.settings[$index].value" ng-click="dropdownItemClicked(name, formData.settings[$index].value)">
<option value="" disabled="disabled">---Please Select Option---</option>
<option ng-repeat="item in section" value="{{item.value}}" ng-bind="item.value">
</option>
</select>
In your controller, create a function to handle this ng-click event:
$scope.dropdownItemClicked = function(name, value) {
console.log(name, value);
// save name/value to database
}
The key is to pass in the exact data you want to save to the database into your dropdownItemClicked() function.

Could you just put the value inside the label?
<label ng-bind="name">{{formData.settings[$index].value}}</label>

There is no way to read from the label. It is the one way binding after all, right. I would do something like this.
var app = angular.module('MyApp', []);
app.controller("MyCtrl", function($scope){
$scope.formData = {
settings:[]
};
$scope.configs = {
'Label1': [{ value: 11 }, { value: 12 }],
'Label2': [{ value: 21 }, { value: 22 }]
};
$scope.change = function(name, idx) {
$scope.formData.settings[idx].name = name;
};
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<div ng-cloak="" ng-app="MyApp">
<form class="form-horizontal" ng-controller="MyCtrl">
<div ng-repeat="(name, section) in configs">
<label ng-bind="name"></label>
<select class="form-control" ng-model="formData.settings[$index].value" ng-change="change(name, $index)">
<option value="" disabled="disabled">---Please Select Option---</option>
<option ng-repeat="item in section" value="{{item.value}}" ng-bind="item.value">
{{item.name}}
</option>
</select>
</div>
<div class="col-md-12" ng-include="gametemp"></div>
<div class="row">
<div class="hr-line-dashed"></div>
<div class="text-center col-md-12 padding-15">
<button class="btn btn-primary btn-lg" ng-click="saveSetting()" formnovalidate translate>
<i class='fa fa-circle-o-notch fa-spin' ng-if="showBusy"></i> Save
</button>
</div>
</div>
<div>
{{formData.settings}}
</div>
</form>
</div>

Creating dropdown at runtime and bind dropdown values after that - not working ngOptions

I am generating dropdown at runtime using AngularJs. I also want to bind corresponding options with it which will be generated based on dropdown type being created.
<div class="form-group" ng-repeat="attrib in col1Attribs">
<label class="control-label" for="txtCode">{{attrib.displayText}}</label>
<select class="form-control"
ng-options="item.configValue for item in configOptions(attrib.configType)" />
</div>
My controller has following method.
$scope.configOptions = function (type){
return SmartCache.get(type); //SmartCache is my cacheFactory
}
EDIT:
Here is my data when parameter type = 'Status'
[{"$id":"1","people":[],"configId":"STAT001","configValue":"Active","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Active","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHM=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]},{"$id":"2","people":[],"configId":"STAT002","configValue":"Suspended","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Suspended","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHQ=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]},{"$id":"3","people":[],"configId":"STAT003","configValue":"Terminated","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Terminated","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHU=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]},{"$id":"4","people":[],"configId":"STAT004","configValue":"Deleted","startDate":"2014-01-31T00:00:00","endDate":"9999-01-01T00:00:00","description":"Deleted","status":1,"parentId":null,"isSelectable":true,"timestamp":"AAAAAAAAKHY=","isSystemData":true,"children":[],"parent":null,"personAttributes":[],"items1":[]}]
I am able to achieve my task using code below but not using ngOptions.
<div class="form-group" ng-repeat="attrib in col1Attribs">
<label class="control-label" for="txtCode">{{attrib.displayText}}</label>
<select class="form-control">
<option ng-repeat="c in configOptions(attrib.configType)" value="{{c.configId}}">
{{c.configValue}}</option>
</div>
</div>
Try this jsFiddle

I can't see the rest of your code. Here is a snippet of how to create the dropdown:
<select data-ng-options="e.description for e in configOptions" data-ng-model="selectedOption" />
Demo:http://plnkr.co/edit/YcuqZ1gs4iDAAgfLrZPO?p=preview

Probably you are trying this
Use as
<select class="form-control"
ng-options="item.configId as item.configValue for item in configOptions(attrib.configType)" />
configId adds as option value and configValue as display value.
