Save check box values to firebase

In my form I have several checkboxes. All selected checkbox values should be written in firebase database. However, cannot manipulate the checkboxes. My code does not take the checkbox values. It does not appear on firebase. My form looks like this [![Form][1]][1]

HTML Code
<td>
<label>
<input class="paint" id = "paint" value="Anti-Fungus Paint" type="checkbox" unchecked> Anti-Fungus Paint
</label>
<label>
<input class="paint" id = "paint" value="Emulsion Paint" type="checkbox" unchecked> Emulsion Paint
</label>
<label>
<input class="paint" id = "paint" value="Anti-Corrosive Paint" type="checkbox" unchecked> Anti-Corrosive Paint
</label>
<label>
<input class="paint" id = "paint" value="All in one Paint" type="checkbox" unchecked> All in one Paint
</label>
</td>
Javasript
document.getElementById('formBid').addEventListener('submit',function(e){
e.preventDefault();
var id=Date.now(); //generating a unqiue id
set(ref(db,'quotes/' + id),{
paint:document.querySelectorAll('input[id="paint"]:checked'),
});
alert('Quote Sent To Client');
formBid.reset();

first, you should difference the id of each checkbox, the id should be unique to make it works.
I usually use getElementById to get each value because it's easier for me.

How to get the boolean value based on radio button selected in html using angular

I have created two radio buttons like Order, and Cart as like below, and I just want to get the TRUE (if the radio button is checked and by default Order button is checked) and FALSE if its not checked in app.component.ts file in angular JS.
app.component.html
<div class="container">
<form>
<label class="radio-inline">
<input type="radio" name="optradio" checked id="place_Oreder">Order
</label>
<label class="radio-inline">
<input type="radio" name="optradio" id="add_cart">Cart
</label>
</form>
</div>
I just written the following code which say if there is onclick on both button the boolean value will change:
isSelectedMSM:boolean=false;
isSelectedLive:boolean=false;
$(document).ready(function(){
$("#place_Oreder").click(function(){
this.isSelectedOrder=true;
});
});
$(document).ready(function(){
$("#add_cart").click(function(){
this.isSelectedcart=true;
});
});
I'm not sure that How can I print TRUE or FALSE in app.components file based on the radio button selected by user based on that I need to put if condition and call an appropriate service to invoke.
Can someone help me to achieve this? I just googled but I didn't find the right resource to implement the same. It would be much helpful if someone share your experience to solve this.
Update:
I'm not sure the above code will work. But can someone lead me that how can I achieve this in better way.

A simple click event will do the trick
<label class="radio-inline">
<input type="radio" name="optradio" checked id="place_Oreder" (click)="onClick('order')">Order
</label>
<label class="radio-inline">
<input type="radio" name="optradio" id="add_cart" (click)="onClick('cart')">Cart
</label>
comp.ts
onClick(item) {
if(item == 'order')
this.isSelectedOrder = true;
else if(item == 'cart')
this.isSelectedCart = true;
}

You can use ngForm for this, pass ref to function and from component, get the values as required.
Demo (Check console.)
HTML
<div class="container">
<form #myForm="ngForm" (submit)="submitForm(myForm)">
<label class="radio-inline">
<input ngModel type="radio" name="optradio" checked value="true" id="place_Oreder">Order
</label>
<label class="radio-inline">
<input ngModel type="radio" name="optradio" value="false">Cart
</label>
<button type="submit">Submit</button>
</form>
</div>
Component
submitForm(form: NgForm) {
console.log(form.value);
}

select default for radio buttons inside a loop modelled with dynamic ngModel

I have a for loop containing inputs, each loop consists of five radio values whose name and model are dynamic.
I want to set value 1 as default, I can use the usual html "checked" or "checked = checked" but it works only without ngModel, if I'm using ngModel, I have to initialize it in the component class but since, it's dynamic there's no way I can initialize it first.
Is there any alternative or am I missing anything??
<div class="scorecard-attribute" *ngFor="let attribute of opportunity.scorecard.scorecard_attributes">
<input type="radio" name="{{attribute.name}}" [value]=1 [(ngModel)]="newRating[attribute.id]" checked>
<input type="radio" name="{{attribute.name}}" [value]=2 [(ngModel)]="newRating[attribute.id]">
<input type="radio" name="{{attribute.name}}" [value]=3 [(ngModel)]="newRating[attribute.id]">
<input type="radio" name="{{attribute.name}}" [value]=4 [(ngModel)]="newRating[attribute.id]">
<input type="radio" name="{{attribute.name}}" [value]=5 [(ngModel)]="newRating[attribute.id]">

You can try this code in your HTML file,
<div class="scorecard-attribute" *ngFor="let attribute of opportunity.scorecard.scorecard_attributes">
<input type="radio" [value]="attribute" [(ngModel)]="newRating" (click)="click(attribute)">{{attribute.name}}
</div>
Add this code in component file,
newRating:any=opportunity.scorecard.scorecard_attributes[0];
click(obj){
console.log(obj);
}

Problems with retrieving radio button value for feedback form

I'm trying to build a simple feedback form. The user will answer a series of yes or no questions. If they choose no, then they will be provided with a comment form to include text.
Currently, I'm having problems with retrieving radio button values. I am trying to print them in the console, but nothing happens when I choose the appropriate choice. If the user chooses 'no', it needs to be able to remember the comment that will get submitted.
My JSFiddle is here: http://jsfiddle.net/787x18vx/
HTML
<p>You are providing feedback</p>
<form>
<div id="question-1">
<label for="question-1">Is this correct?</label>
<input type="radio" value="yes" name="choice-1" />Yes
<input type="radio" value="no" name="choice-1" />No
</div>
<div id="question-2">
<label for="question-2">Another question</label>
<input type="radio" value="yes" name="choice-2" />Yes
<input type="radio" value="no" name="choice-2" />No
</div>
<div id="question-3">
<label for="question-3">One more question</label>
<input type="radio" value="yes" name="choice-3" />Yes
<input type="radio" value="no" name="choice-3" />No
</div>
<br />
<button>Send Feedback</button>
</form>
jQuery
var firstInput = 'input[name=choice]';
var firstInputValue = $('input[name=choice-1]:checked').val();
$(firstInput).on('click', function() {
console.log(firstInputValue);
console.log($('input[name="choice-1"]:checked').val());
console.log($('input[name="choice-2"]:checked').val());
// if value === 'no' show comment form
});

You are using input[name=choice] selector which is not exisiting.
Use input[type=radio] instead.
var firstInput = 'input[type=radio]';
var firstInputValue = $('input[name=choice-1]:checked').val();
$(firstInput).on('click', function() {
console.log(firstInputValue);
console.log($('input[name="choice-1"]:checked').val());
console.log($('input[name="choice-2"]:checked').val());
// if value === 'no' show comment form
});
Fiddle

var firstInput = 'input[name=choice]';
This is looking for something specifically with the name choice, which doesn't appear to be in your html.
There are two quick ways about this.
First, just change your selector:
$('input[type=radio]').on('click', function(){...
This will trigger the function on a click of any radio
Another way is with the wildcard selector:
var firstInput = 'input[name^=choice]';
The ^ should make is so any input with the name starting with choice gets selected.
This method should work, but targeting input[type=radio] is probably a better solution,

You are missing the -1 in your name
var firstInput = 'input[name=choice-1]';

Your selector is trying to get tags with name exactly equals 'choice'. You can search by prefix with the following
var firstInput = 'input[name|="choice"]';
This will get all tags which name starts with 'choice'

Validating if atleast one checkbox is checked or one input field is filled

I need better validation logic, where some Checkboxes and some input fields are grouped together.
The user either have to check at least one checkbox or have to fill at least one input box.
If a checkbox is checked or an input field is filled then the complete group is validated.
What will be the best possible way to validate such a situation?
e.g
<input class="checkbox" type="checkbox" name="check-deal" value="1" grouped="deal" >
<input class="checkbox" type="checkbox" name="check-deal" value="2" grouped="deal">
<input class="checkbox" type="checkbox" name="check-deal" value="3" grouped="deal">
<input class="checkbox" type="checkbox" name="check-deal" value="4" grouped="deal">
<input class="input-group" type="text" name="deal-name1" value="" grouped="deal">
<input class="input-group" type="text" name="deal-name2" value="" grouped="deal">
I have defined an extra attribute grouped for all input and checkboxes that should be grouped togather
but getting no idea how to validate the group as best practice.

DEMO
Point No.1 : There isn't any attribute called grouped for html as of my knowledge but I would suggest you to use data-* prefixed attribute names like data-grouped or data-anyname which is valid
Point No.2 : I rather categorized your checkboxes and textboxes into separate divs and below is how it is:
<div class="chkbox">
<input class="checkbox" type="checkbox" name="check-deal" value="1" />
<input class="checkbox" type="checkbox" name="check-deal" value="2" />
<input class="checkbox" type="checkbox" name="check-deal" value="3" />
<input class="checkbox" type="checkbox" name="check-deal" value="4" />
</div>
<div class="txtbxs">
<input class="input-group" type="text" name="deal-name1" value="" />
<input class="input-group" type="text" name="deal-name2" value="" />
</div>
<button class="btnValidate">Validate</button>
Point No.3 : Below is how you can validate using jquery
$('.btnValidate').on('click',function(){
var chkLength=$('.chkbox .checkbox:checked').length; //get checkbox checked length
var filledText=$(".txtbxs .input-group").val()!="";
//get bool value whether any of the text box is filled or not
if(chkLength || filledText) //check with or condition
alert('valid')
else
alert('invalid');
});
UPDATE
DEMO
As #AkshatG pointed in his answer the discrepancy was there in my answer so I've edited it and here is the updated solution.
$('.btnValidate').on('click',function(){
var chkLength=$('.chkbox .checkbox:checked').length;
var filledText=false; //First set it to false
$.each($(".txtbxs .input-group"),function(index,value){
if($(value).val()!="")
{
filledText=true//if it finds any value then set it to true
return;//break from $.each
}
})
if(chkLength || filledText)
alert('valid')
else
alert('invalid');
});

You first need to take count of each validations. And then check if any of the two has count greater than 0 or not. Guruprasad's answer won't work if you enter text on second textbox because it won't filter all the textboxes. You have to use filter function for this :
$("input[type='text'],textarea").filter(function() {
return $(this).val() != "";
}).length;
Here's a jsfiddle :

Hope this helps.
