jQuery input element with id selection using id selector

I am using JQuery 3.6 and I'm trying to create a simple email registration snippet on a page.
I am surprised that when I type an email in the input, and click the button, the alert box shows a blank. I get the same result when I use Code Inspector. The element is identified and selected correctly, but for some reason, I can't seem to extract the email value entered in the input box.
Here is my markup and minimal Javascript:
<div class="g-mb-30">
<div class="input-group border-0 rounded">
<input id="newsletter-subscription-email" class="form-control border-0 g-pa-12" type="email" title="Subscribe to our newsletter!" placeholder="Email address">
<div class="input-group-append p-0">
<button id="newsletter-subscribe" class="btn btn-primary" type="submit" role="button">Subscribe</button>
</div>
</div>
</div>
<script type="text/javascript">
function isValidEmail(some_email){
/* impl detail */
}
$().ready(function(){
$('#newsletter-subscribe').on('click', function(e){
let email = $('#newsletter-subscription-email').val().trim().toLowerCase();
alert(email); // displays blank if even I type an email address
if (email.length && isValidEmail(email)) {
e.preventDefault();
// some logic ...
}
}
});
</script>
Why is the address not being correctly retrieved - since the selector CSS is correct - and how do I fix this to correctly retrieve the entered email?

I faced the same thing with you months ago.
At last, I found that there were two controls with the same ID, jquery always choose the first one with the ID
your code is perfect, please check is there are more than one input with that ID attr

Probably the $()ready(function(){ and also a missing }); in the js.
$(function() {
$('#newsletter-subscribe').on('click', function(e){
let email = $('#newsletter-subscription-email').val().trim().toLowerCase();
alert(email); // displays blank if even I type an email address
if (email.length && isValidEmail(email)) {
e.preventDefault();
// some logic ...
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
<div class="g-mb-30">
<div class="input-group border-0 rounded">
<input id="newsletter-subscription-email" class="form-control border-0 g-pa-12" type="email" title="Subscribe to our newsletter!" placeholder="Email address">
<div class="input-group-append p-0">
<button id="newsletter-subscribe" class="btn btn-primary" type="submit" role="button">Subscribe</button>

how to concatenate a string in controller side to autofill form?

I have a bootstrap form where user enter an email I want if user doesn't enter #scoops.com it concatenates automatically either form side or controller side
In controller it saves using this $customer->email = $request->email; if want to check at controller side how I can check if user enters #scoops.com at the end of user name. If it is missing then concatenate #scoops.com with user name
<div class="form-group">
<label>Email <span style="opacity: 0.5; font-style: italic; color: red;">(Required)</span></label>
<div class="input-group">
<input type="search" name="email" id="email" autocomplete="off" class="form-control input-lg" placeholder="Enter Email" name="name" required="#scoops.com" / onfocus='tmp=this.value;this.value=""' onblur='if(this.value=="")this.value=tmp'>
<div class="input-group-append">
<span class="input-group-text">#scoops.com</span>
</div>
</div>
<ul id="suggested-emails" class="list-group"></ul>
<span id="error_email"></span>
#if($errors->has('email'))
<div class="alert alert-danger">
{{ $errors->first('email') }}
</div>
#endif
</div>
`

Something like:
$customer->email = $request->email;
if (!preg_match('/^.*#scoops.com$/', $customer->email)) {
$customer->email .= '#scoops.com';
}
The risk is if they put in anything#example.com, you'll then get anything#example.com#scoops.com. It probably needs something additional to check if it looks like an email address already (i.e. has at least an "#" in it).

First of all you will check if #scoop.com is present or not like below:
use Illuminate\Support\Str;
$myString = '#scoop.com';
$contains = Str::contains($request->email, '#scoop.com');
$contains will either true or false
if it's false then concatenate #scoop.com as below
$newString = $request->email.$myString;

Python-requests module, post two "values" to renew&scrape website

The first part was already answered, however, EDIT isn't.
I am using python and the requests module to scrape a website. Therefore I have to “click” a Renew-Button, which is a link(href) wrapped in an image “pat_renewmark.gif”.
html
<form name="checkout_form" method="POST" id="checkout_form">
<input type="HIDDEN" id="checkoutpagecmd">
<a href="#" onclick="return submitCheckout( 'sortByCheckoutDate', 'bycheckoutdate' )">
<img src="/screens/pat_sortbychkout.gif" alt="SORT BY DATE CHECKED OUT" border="0">
</a>
<input type="HIDDEN" name="currentsortorder" value="current_duedate">
<a href="#" onclick="return submitCheckout( 'requestRenewSome', 'requestRenewSome' )">
<img src="/screens/pat_renewmark.gif" alt="RENEW SELECTED ITEMS" border="0">
</a>
</form>
javascript (submitCheckout)
function submitCheckout(buttonname, buttonvalue)
{
var oHiddenID;
oHiddenID = document.getElementById("checkoutpagecmd");
oHiddenID.name = buttonname;
oHiddenID.value = buttonvalue;
//c29364j/c1365070 - prevent the patron from submitting twice
var oButtonSpan;
oButtonSpan = document.getElementById("checkoutbuttons0");
if (oButtonSpan) oButtonSpan.style.display = "none";
oButtonSpan = document.getElementById("checkoutbuttons1");
if (oButtonSpan) oButtonSpan.style.display = "none";
document.getElementById("checkout_form").submit();
return true;
}
Apparently submitCheckout passes .name and value, which are both assigned to ”requestRenewSome”’, to the hidden input with theid=“checkoutpagecmd”`.
I’ve worked with the requests module before and I am able to handle a simple username&password input , for example:
html
<div class="formEntryArea">
<label for="extpatid">
<span class="formLabel">
Your username:
</span>
</label>
<input name="extpatid" id="extpatid" value="" size="20" maxlength="40">
<label for="extpatpw">
<span class="formLabel">
Your password:
</span>
</label>
<input name="extpatpw" id="extpatpw" type="PASSWORD" value="" size="20" maxlength="40">
</div>
python
import requests
with requests.Session() as c:
LOGIN_URL = "https://example.com"
USERNAME = “XXXXX”
PASSWORD = “YYYYY”
source = c.get(LOGIN_URL)
data_load = dict(extpatid=USERNAME,extpatpw=PASSWORD)
head_load = dict(referer=LOGIN_URL)
c.post(LOGIN_URL, data=data_load, headers=head_load)
However, here c.post is handling only one “value” per input (either USERNAME or PASSWORD) and no javascript code is included.
As it seems, for the problem above I somehow have to post the two attributes/strings
.name = 'requestRenewSome'
.value = 'requestRenewSome'
? Or is the approach completely different to the example I attached?
EDIT
The answer from matino (or the comment from t.m.adam) solves the problem! Unfortunately the User then has to approve that he is sure he wants to renew by clicking a YES button.
html
<form name="checkout_form" method="POST" id="checkout_form">
<input type="HIDDEN" id="checkoutpagecmd">
<input type="HIDDEN" name="currentsortorder" value="current_duedate">
<span id="checkoutbuttons0">
<input type="SUBMIT" name="renewsome" value="YES">
<input type="SUBMIT" name="donothing" value="NO">
</span>
</form>
I therefore added 'renewsome': 'YES'to the data_load dictionary, but thats not enough. I don't know the value for the hidden input/s? id=checkoutpagecmd and/or? name=currentsortorder but couldn't find any answer on how to proceed.
P.S. I know it's actually a knew question, and I'm going to separate it, if it's getting answered.

What the javascript code actually does is dynamically assigning name and value to the hidden input. So in the end there can be 2 cases:
<input type="hidden" id="checkoutpagecmd" name="sortByCheckoutDate" value= "bycheckoutdate">
or
<input type="hidden" id="checkoutpagecmd" name="requestRenewSome" value= "requestRenewSome">
Knowing that, you can send http request like this:
requests.post(url, data={'sortByCheckoutDate': 'bycheckoutdate'}) # 1st case
requests.post(url, data={'requestRenewSome': 'requestRenewSome'}) # 2nd case

How to show a blue colored progress bar exactly like gmail's horizontal blue colored progress bar which is displayed when user submits the form?

I'm using Bootstrap v3.3.5 in my website.
In one scenario I'm displaying a form in Bootstrap modal dialog. User fills in the data and submits the form. After submitting the form the form looks as it is until the response is received from the server.
So, what I want to do is display a blue colored horizontal progress bar exactly resembling the blue colored horizontal progress bar which gmail uses when it loads the inbox mail list after login. This progress bar should be dynamic like gmail's progress bar(i.e. progressive in nature and not like revolving circle loader image).
It should be displayed at the top of form with the message "Please wait...your event is being generated." I've added a comment in my code telling where it should be displayed exactly.
Following is my Bootstrap modal's HTML code:
<form method="post" action="{$site_url}add_event.php" id="formAddEvent" >
<!-- The gmail look alike loader should display here only upon successfull submission of a form. -->
<div class="form-group" id="addEventErrorMsg" style="display:none; color:#FF0000;">
</div>
<div class="form-group">
<input type="text" name="txt_event_title" id="txt_event_title" autocomplete="off" class="form-control custom-height" placeholder="Event Title" style="height:30px;" />
</div>
<div class="form-group">
<textarea type="text" name="txt_event_description" id="txt_event_description" autocomplete="off" class="form-control custom-height" placeholder="Description (optional)" style="height:60px;" ></textarea>

$("#myModal-add-event").hide();
//window.location = site_url + "event_index.php";
window.location.href = site_url + "event_index.php";
return false;
} else {
$("#btn_add_event").attr('disabled', false);
$("#addEventErrorMsg").show();
$("#addEventErrorMsg").html(data);
}
},
error: function() {}
});
})
});
Please help me. Thanks.
My question is different than any other question. I don't know how to work the progress bar percentage or progress with the response time. I'm not getting solution for it from anywhere. Please remove the tag of duplicate from my question.

No it's not different, and therefore it is duplicate of

This code snippet shows the essential part for a progress bar.

Meteor Accounts - Login forms change HTML remove dropdown JS

How do I modify Meteor's Accounts-ui to change the classes and the html tags rendered without re-writing all the accounts-ui logic?
For example I'd like to remove the "dropdown" behavior and just display the form directly in my page.
I read this answer but it doesn't go into detail - it just removes the default CSS. I'd like to go a bit deeper..

I figured this out for another answer, but thought I'd put it in here since it seems like a quicker way to get what you want.
Template.login.rendered = function()
{
Accounts._loginButtonsSession.set('dropdownVisible', true);
};
(Template.login should be Template.yourTemplateWithLoginButtons)

Styling
Remove accounts-ui
meteor remove accounts-ui
Add accounts-ui-unstyled & less
meteor add accounts-ui-unstyled
meteor add less
Finally, add the following file to your project directory & edit it to your viewing pleasure
https://github.com/meteor/meteor/blob/master/packages/accounts-ui/login_buttons.less
More customization
You can edit the accounts-ui package and edit html & js without starting from scratch:
Remove the accounts-ui-unstyled package and add the stuff in the dir below (except package.js & accounts_ui_tests.js) to your project's client dir, add accounts-urls and edit it to fine tune it to your spec.
https://github.com/meteor/meteor/tree/master/packages/accounts-ui-unstyled
Until meteor gives us a way to specify load order
Rename the following files so they load in the correct order
1accounts_ui.js
2login_buttons.html
3login_buttons_single.html
4login_buttons_dropdown.html
5login_buttons_dialogs.html
6login_buttons_session.js
7login_buttons.js
8login_buttons_single.js
9login_buttons_dropdown.js
login_buttons_dialogs.js

If all you want to do is remove the drop down behavior, then it would suffice to just add the accounts-ui-unstyled package and hide the components you don't want visible: e.g.:
.login-link-text { display: none; }
in your CSS to hide the Sign in link.
Here are the relevant id's and classes that you look into styling:
#forgot-password-link
#login-buttons
#login-buttons-password
#login-dropdown-list
#login-email
#login-email-label
#login-email-label-and-input
#login-password
#login-password-label
#login-password-label-and-input
#login-sign-in-link
#signup-link
.accounts-dialog
.additional-link
.additional-link-container
.login-button
.login-button-form-submit
.login-buttons-dropdown-align-left
.login-close-text-clear
.login-close-textClose
.login-form
.login-form-sign-in
.login-link-and-dropdown-list
.login-link-text
.login-password-form

Create your own html template similar to this below. Style it to your taste.
meteor add accounts-password accounts-ui
<template name="login">
<form class="login-form">
<div class="panel panel-default">
<div class="panel-heading">
<h3>Login</h3>
</div>
<div class="panel-body">
<div class="form-group">
<label>Email</label>
<input type="email" class="form-control" id="email" placeholder="Email address">
</div>
<div class="form-group">
<label>Password</label>
<input type="password" class="form-control" id="password" placeholder="password">
</div>
</div>
<div class="panel-footer">
<button type="submit" class="btn btn-danger btn-lg">Login</button>
</div>
</div>
</form>
</template>
You can now call Meteor.loginWithPassword in the template event like so:
Template.login.events({
'submit .login-form': function(e) {
e.preventDefault();
var email = e.target.email.value;
var password = e.target.password.value;
Meteor.loginWithPassword(email, password,function(error){
if(error) {
//do something if error occurred or
}else{
FlowRouter.go('/');
}
});
}
});
You can create another form for registration as well.
Just call Accounts.createUser(object, callback);
