Manipulating the DOM of a collection of divs using Jquery

Am working on the frontend part of an application whereby I have
some form inputs (wrapped in divs). Each div has a button called
Add Beneficiary. Basically when the user clicks on the button, the div
below it should be displayed (which is hidden by default) and the
sequence continues (each button on a div clicked the div below it
displays).
On the button of each div I have writen some logic whereby on click event
a function called addBeneficiary is triggered. I parse the id of the
button clicked. Next in the function I manipulate the DOM by reaching
out to the parent div and displaying it but the logic does not
work.
~ Kindly assist?

Logic
function addBeneficiary(beneficiary){
let check = $('#' + beneficiary).parents('div').last().prop('id');
//console.log(check);
$("check").css("display", "block");
}

Its not working because both parents div id is "beneficiary1". And you can't use same id with multiple tag. It should be unique like beneficiary1, beneficiary2 & so on... And also little bit change into your script.
function addBeneficiary(beneficiary){
let check = $('#' + beneficiary).parents('div').next('div');
//console.log(check);
check.css("display", "block");
}

How to add dynamic data attribute value to a button and a div generated by repeater.js

I am using repeater.js to repeat a div with some input fields and button, but the problem is that i want to give each and every div a unique id so that i can extract data from all the fields of that particular div input elements.
this is the HTML Code:
<div class="form-group mt-repeater">
<a href="javascript:;" data-repeater-create class="btn btn-circle purple mt-repeater-add">
<i class="fa fa-edit"></i> Repeat Field
</a>
<div data-repeater-list="group-b">
<div data-repeater-item class="mt-repeater-item">
<div class="mt-repeater-cell">
<div class="row">
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="dosage_form" class="form-control typeahead-findings circle-input" placeholder="Dosage Form">
<label for="dosage_form">e.g. Tablet / Syrup / Capsule etc.</label>
</div>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="brand_name" class="form-control typeahead-findings circle-input" placeholder="Brand / Generic Name">
<label for="brand_name">e.g. Dytor</label>
</div>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<input class="form-control circle-input" id="contents" type="text" placeholder="Contents" />
<span class="help-block"> e.g Paracetamol </span>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="dose" class="form-control typeahead-findings circle-input" placeholder="Dose">
<label for="dose">e.g. 20 mg / 20 ml</label>
</div>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<input class="form-control circle-input" id="dose_regimen" type="text" placeholder="Dose Regimen" />
<span class="help-block"> e.g 1-1-1-1 </span>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<div class="input-group">
<input type="text" id="therapy_duration" class="form-control typeahead-findings circle-input" placeholder="Therapy Duration">
<label for="therapy_duration">e.g. 1 Day / 1 Month etc.</label>
</div>
</div>
</div>
<div class="col-md-1 col-sm-6 col-xs-6">
<i class="fa fa-plus"></i>
</div>
<div class="col-md-1 col-sm-6 col-xs-6">
<i class="fa fa-minus"></i>
</div>
</div>
</div>
</div>
every time i click on the add repater button this div gets replicated but what i also want is that the new div generated should have a unique div id also the curresponding elemnts inside it should have a class or id starting with that id so that data extraction can be easy for that particular div
I was using this Jquery code:
$(".addData").on('click' ,function()
{
alert("hi");
});
This is the repeater i am using: https://pastebin.com/n7g7tdTH
but this code only runs for the very first div on the later generated dynamic divs it doesn't run. I also tried editing the repeater.js but no success because its all dynamic and i am not able to understand where i should edit that code to add a dynamic data-counter value for the div and the corresponding elements.
Can anyone help with this logic?

Another option, to retrieve field values would be to rename all input field id with name (example below) and use repeater.js repeaterVal() to get all the field values .
$(".mt-repeater").repeater();
$("#getVal").click(function () {
$('.mt-repeater').repeaterVal()["group-b"].map(function(fields){
//fields contain the collection of input fields per row
console.log(fields["dosage_form"]);
console.log(fields["brand_name"]);
//....
})
})

<button id="getVal">Get Value</button>

For the first problem..
but this code only runs for the very first div on the later generated
dynamic divs it doesn't run
You can convert your jquery events into delegated events.. These allow you to catch events on DOM elements based on a selector, so when newer DOM elements are added these are caught too.
So -> $(".addData").on('click' ,function()
As a delegated event becomes -> $(document.body).on("click",".addData" ,function()
The second problem.
but how to get the values from the input field that are present near that button
This can be achieved by traversing up the DOM tree to a parent that surrounds the elements you want,. eg. .row or maybe mt-repeater-cell, as long as it's a DOM element that contains the elements you want to find. Here you can use jquery's closest selector, that will traverse up the tree until it finds the element your after.
So -> $(this).closest('.row').find('#dose_regimen').val()
The above will traverse up the DOM tree until it finds a .row class, we then find element with id dose_regimen etc,.. #dose_regimen and then finally get it's value with .val()

JavaScript Pop-Up Dialog Not Being Read by Web Accessibility Screen Reader

I have a project requirement in which the web page I am building in question needs to be read by the JAWS screen reading software, but the client only has access to JAWS 11 as their latest version.
We currently have JavaScript-based pop-up dialogs for many of the forms on the web and right now a big problem is that the JAWS 11 software cannot read the below pop-up text. What is wrong with the pop-up dialog below (in HTML)?

Setting the main content to aria-hidden='true' tells the screen reader to stop reading the content there.
Try using aria-hidden='false'

How are you opening the modal? Because with a tabindex of -1 on the wrapper div, you will only be able to send the screenreader and keyboard focus to the modal via JavaScript. In that case it's best to make moving the focus part of the script which opens the modal.
On the other hand, if it's opened via a link, you can just remove that tabindex attribute altogether and put the id of the wrapper div in the link href, e.g. <a href=#EditContentModal>
Either way, remember to send focus back to where it started when the modal is closed.
Edited to clarify: the tabindex="-1" attribute on your wrapper div is preventing keyboard access. Remove it. See MDN's tabindex reference: a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation.

Send form data in a querystring to url with AngularJS

I am trying to create a simple for that then passes the data into a querystring.
ie capturing:
first name
last name
email
Which when submitted with give soemthing like:
http://www.url.com?FirstName=John&LastName=Smith&johnsmith#url.com
I thought I would try 2 way binding and add the querystrings via the action but obviously this gave me an error. I don't need to save this data trust transfer it from a small form to the main application.
I also tried doing this all on submit which works however the link is still clickable when the form is blank. Any suggestions would be very welcome.
<form class="form" name="appForm" novalidate action="https://www.url.com?FirstName={{firstname}}" method="Post">
<div class="row">
<div class="col-md-12">
<div class="row">
<div class="col-md-11 flowuplabels">
<div class="form-group has-feedback" show-errors="{ showSuccess: true }">
<div class="fl_wrap">
<label for="appfirstname" class="fieldLabel fl_label">
First name<span class="text-danger">*</span>
</label>
<input type="text" name="appfirstname" id="appfirstname" class="form-control fl_input" data-ng-model="firstname" ng-required />
<span class="form-bar"></span>
</div>
</div>
<div class="form-group has-feedback" show-errors="{ showSuccess: true }">
<div class="fl_wrap">
<label for="applastname" class="fieldLabel fl_label">
Last name<span class="text-danger">*</span>
</label>
<input type="text" name="applastname" id="applastname" class="form-control fl_input" data-ng-model="lastname" ng-required />
<span class="form-bar"></span>
</div>
</div>
<div class="form-group has-feedback" show-errors="{ showSuccess: true }">
<div class="fl_wrap">
<label for="appemail" class="fieldLabel fl_label">
Email<span class="text-danger">*</span>
</label>
<input type="email" name="appemail" id="appemail" class="form-control fl_input" data-ng-model="email" ng-required />
<span class="form-bar"></span>
<p ng-show="appForm.appemail.$invalid && !appForm.appemail.$pristine" class="help-block">Enter a valid email.</p>
</div>
</div>
<div class="form-group">
<button id="btnSend" class="btn btn-red" ng-disabled="!firstname || !lastname || !email">Join us</button>
</div>
</div>
</div>
</div>
</div>
</form>

Typical as soon as I ask I solve
should have used get and just put the url ie:
It will then ass the query string using the input name as the query name so much simpler that what I was trying to do

Unable to make html/java script form function correctly

I'm struggling with a solution for this. I have the first block of code, which I want to use for css formatting/look feel etc.
<div class="login-form">
<!-- Start Error box -->
<div class="alert alert-danger hide">
<button type="button" class="close" data-dismiss="alert"> ×</button>
<h4>Error!</h4>
Your Error Message goes here
</div> <!-- End Error box -->
<form action="#" method="get" >
<input type="text" placeholder="User name" class="input-field" required/>
<input type="password" placeholder="Password" class="input-field" required/>
<button type="submit" class="btn btn-login">Login</button>
</form>
</div>
Then I have this separate code that uses a script to submit the user info once entered. I want to move the actions that this script performs onto the above code. Therefore having the look and feel of the first block of code and the actions of the second.
I'm learning at the moment, so it seems logical to try and use example code that exists as a starting point. I'm not able to find any help on goofle that direcly helps resolve this question.
I think if I could work out if I can wrap the script around the top block I could get it from there, just need some direction.
<div class="container" id="login-block">
<script type="text/template" id="login-template">
<header id="header"></header>

<input type="text" id="login-username" placeholder="Username" />
<input type="password" id="login-password" placeholder="Password" />
<button>Log In</button>
</form>
</script>

This is what I wanted to achieve. Works now, only taken 3 hours to work it out ;-/
