Populating large HTML div in JavaScript, based on JSON response from AJAX call

I currently have a significant amount of HTML inside a div which is generated within an iteration from a GET request to my .net core server.
Some of the values in the HTML is dynamic data returned from the server.
I've added a button to my website, which when pressed, makes an AJAX call to the server to return a JSON object representing the dynamic values for the next iteration.
So, I would like the JavaScript to add a new div to the DOM, which is the same, and has my dynamic values populated based on the JSON response.
For context, the DIV looks like this (which is from a bootstrap template I purchased):
<div class="card">

Question:
There's a lot of HTML here. What's the best way to build this out in Javascript? Is it just a case of biting the bullet and writing all of the JS code to create each element/class?
Would this be the best practice? Because it effectively means I'm maintaining the HTML markup in two places..
Thank you..!

I usually save the html of the template to be rendered inside an hidden element. Then I can always access it using that element.innerHTML. You could use specialized script tag instead. But the innerHTML part is the same.
After having the HTML as string you have 2 options
build the string with the values you want to populate, then add that as innerHTML to the target container.
but a better approach is to create an element from that html (see function below) then append it and manipulate it otherwise.
// render 5 cards
for (var i = 0; i < 5; i++) {
var html = document.querySelector("#card-template").innerHTML;
var elem = elemFromString(html)
// change something
elem.querySelector(".card-body>p strong").innerText = "card " + i
// append
document.querySelector("#container").append(elem)
}
// usefull utility
function elemFromString(html) {
var dummy = document.createElement("div");
dummy.innerHTML = html.trim();
if (dummy.children.length > 1) {
console.error("expecting one wrapping element for html. will return only firstChild")
}
var result = dummy.firstChild;
result.parentNode.removeChild(result)
return result;
}

HTML file not loading properly in django

I am trying to integrate my django app with a admin dashboard from github. I can see after my successful log in the app get directed to dashboard but only the HTML part is loading i can't see any fancy things getting added to my dashboard
.
It should have been looking like the one screenshot given in github link. I am not a regular frontend developer so it's getting hard for me figure out where the mistake is.

{% load static %}

Bootstrap closed.bs.alert doesnt fire when alert is being dynamically created

I have a page where I let the user search for information, and it displays an alert at the top stating that he is searching. He is then shown a filtered result. If he clicks the alert dismiss button, the main page is to be reloaded.
However I find that the dismissed event closed.bs.alert is never fired.
My javascript code:
$("document").ready(function () {
$('body').on('click', '#mainsearch', function (event) {
url = window.location.href;
console.log('Clicked');
SearchPatients();
});
$('body').on('closed.bs.alert', "#srpatalert", function () {
console.log('Closed alert');
window.location.href = "/appointments/patients";
});
$(function () {
$('#srpatalert').on('closed.bs.alert', function () {
console.log('Closed alert');
window.location.href = "/appointments/patients";
});
});
});
function SearchPatients() {
var srmsgpre = `
<div id="srpatalert" class="mr-3 alert alert-info alert-dismissible fade show" role="alert">
<strong>Searching For`;
var srmcl = ' </strong>';
var srmsgpost = `
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
`;
var breadcrumb = `
<li class="breadcrumb-item">
Home
</li>
<li class="breadcrumb-item">
Patients
</li>
<li class="breadcrumb-item active" aria-current="page">Search results</li>`;
var srstr = $("#searchterm").val();
sralmsg = srmsgpre + 'Patients:' + srmcl + srstr + srmsgpost;
$('#presearch').html(sralmsg);
return true;
}

As you can see above, I tried two different approaches. I'm not able to get the closed.bs.alert event to fire.

Replace
$(function () {
$('#srpatalert').on('closed.bs.alert', function () {
console.log('Closed alert');
window.location.href = "/appointments/patients";
});
});
with
$('#navbar').on('close.bs.alert', '#srpatalert', function () {
console.log('Closed alert');
window.location.href = "/appointments/patients";
});
Notice that, besides delegating the event to #navbar, I also changed the event itself (from closed.bs.alert to close.bs.alert) as closed.bs.alert doesn't seem to fire in this example - I don't know why and, since it's working with close.bs.alert, I didn't investigate further.
Here's a working example:
$("document").ready(function() {
$('body').on('click', '#mainsearch', function(event) {
url = window.location.href;
console.log('Clicked');
SearchPatients();
});
$('#navbar').on('close.bs.alert', "#srpatalert", function() {
console.log('Closed alert');
});
// don't mind next line, it's just for SO:
$(document).on('click', 'a', e => e.preventDefault())
});
function makeAlert(category, term) {
return $('<div />', {
id:'srpatalert',
class:'mr-3 alert alert-info alert-dismissible fade show',
role: 'alert'
}).append($('<strong />',{text:'Searching For ' + category + ': '}))
.append($('<span />', {text: term}))
.append($('<button />', {
type:'button',
class:'close',
'data-dismiss':'alert',
'aria-label':'Close',
html: $('<span />',{
'aria-hidden':true,
html:'×'
})
}))
}
function SearchPatients() {
sralmsg = makeAlert('Patients', $("#searchterm").val());
$('#presearch').html(sralmsg);
return true;
}

As discussed in comments on the accepted answer above, the closed event does not properly bubble even if you use a delegated event and attach the handler to parent. A bit of discussion on this here.
Also, it's important to note that there is a distinct difference between close and closed, which is that the latter fires after the alert has been removed. In some applications this difference may be significant, such as when you need to resize other elements based on changes to the dom.
With that in mind, if you absolutely need to use the closed event, you must dynamically add your handler anytime the alert is created. This could be done in your example code immediately after:
$('#presearch').html(sralmsg);
You could add your handler so it would look like this:
$('#presearch').html(sralmsg);
$('#srpatalert').off().on('closed.bs.alert', function () {
console.log('Closed alert');
window.location.href = "/appointments/patients";
});

Use HTML,CSS and Javascript in java code using IDE Eclipse

I am new to java and stuck in trying to embed the HTML/CSS and Javascript to the java code.
Any pointers will be helpful to finish building my code. I am using Eclipse editor to write my java code.
I have been able to successfully display some part of HTML display in my java code as below however I am trying to achieve a table sort via html/css/javascript and would like to add that too to my java code.
Below is my display.java file
public void transformForRequestSuccessful(MarkupOutput out) {
//Call render methods
renderdisplay(out);
}
public void renderdisplay(MarkupOutput out)
{
out.append("<BR/>");
out.append("<p>Look at the body!</p>");
out.append("<BR/>");
}
Below is the HTML/CSS/JavaScript that can be pasted as is and runs fine.
I saved this HTML file as sort.html and when called independently works fine.
html>
<head>
<meta http-equiv="content-type" content="text/html;charset=Windows-1252">
<script type="text/javascript">
var people, asc1 = 1,
asc2 = 1,
asc3 = 1;
window.onload = function () {
people = document.getElementById("people");
}
function sort_table(tbody, col, asc) {
var rows = tbody.rows,
rlen = rows.length,
arr = new Array(),
i, j, cells, clen;
// fill the array with values from the table
for (i = 0; i < rlen; i++) {
cells = rows[i].cells;
clen = cells.length;
arr[i] = new Array();
for (j = 0; j < clen; j++) {
arr[i][j] = cells[j].innerHTML;
}
}
// sort the array by the specified column number (col) and order
(asc)
arr.sort(function (a, b) {
return (a[col] == b[col]) ? 0 : ((a[col] > b[col]) ? asc : -1 *
asc);
});
// replace existing rows with new rows created from the sorted array
for (i = 0; i < rlen; i++) {
rows[i].innerHTML = "<td>" + arr[i].join("</td><td>") + "</td>";
}
}

</html>
Any help or suggestions how to embed this in java code will be helpful.
My apologies if I sound naive or unaware of the basic java programming.
Thanks

I would use the following frameworks:
Spring IO: https://spring.io/guides/gs/spring-boot/
This example shows you how to create the server and store your HTML/CSS/JavaScript. On the other hand, create a REST service to create a response with your embed HTML code.
JQuery: https://spring.io/guides/gs/consuming-rest-jquery/
This example shows you how to consume a RESTful Web Service with jQuery and append the embed code

In order to escape the special characters you need to integrate the OWASP encoder to encode the data for JS or CSS. Please refer to this link

Although it will not work alone but hope this will help you out to understand the implementation. This is a sample JSP file. In JSP file you can embed java code in the form of tags (scriplet,declarative and expression).

In this, I also made a dynamic table using scriplet tag.

If you're new, you're going to be exposed to many different approaches to accomplishing the same thing - how to get your Java code to work with other web technologies. IMO, Spring Boot is one of the quickest ways to get started, as #pakOverflow mentions above.
Another great (and simple) intro is from MyKong: https://www.mkyong.com/spring-boot/spring-boot-hello-world-example-jsp/
One (of the many) thing to keep in mind is that you want to separate concerns (see https://en.wikipedia.org/wiki/Separation_of_concerns). In Java, strive to have fairly small, simple objects work together to do interesting things rather than putting all your code in a very small number of classes that do everything.

how can i set success alert at middle of the page?

in my application when user update or insert any data that time if return value is 1 then it displays a bootstrap success alert. but it appears at the end of the page and i want it at middle of the page or at the div box footer. here is my code for that page.
ClassConnection.php :
<?php
class connection
{
Public $ServerName="localhost";
Public $ServerUser="root";
Public $ServerPassword="";
Public $DatabaseName="taksicab";
public $mycon=" ";
public $rs = " " ;
public $sql= " ";
public $myquery = " ";
function open_connection()
{
$con=mysql_connect($this->ServerName, $this->ServerUser, $this->ServerPassword);
if(!$con)
{
die("Error in connection .......");
}
else
{
$this->mycon=$con;
return $this->mycon;
}
}
function SelectDB()
{
mysql_select_db($this->DatabaseName);
}
//DBOperations
function DBOperation ($mTable,$mFields,$mValues,$mOperation)
{
$mSQL="";
$mStr="";
$tFields = explode(",",$mFields);
$tValues = explode(",",$mValues);
if($mOperation == "Insert")
{
$mSQL = "Insert into " . $mTable . "( " . $mFields . ") values ( " . $mValues . ")";
$query = mysql_query($mSQL);
}
else if($mOperation == "Update")
{
for($i=0; $i<count($tFields); $i++)
{
if($i== (count($tFields)-1))
{
$mStr = $mStr . " " . $tFields[$i] . " = " . $tValues[$i];
}
else
{
$mStr=$mStr . " " . $tFields[$i] . " = " . $tValues[$i] . " , ";
}
}
$mSQL = "Update " . $mTable . " set " . $mStr . " Where " . $tFields[0] . " = " . $tValues[0];
$query = mysql_query($mSQL);
}
else if($mOperation == "Delete")
{
$mSQL = "Delete from " . $mTable . " Where " . $tFields[0] . " = " . $tValues[0];
}
// echo $mSQL;
$this->myquery = $query ;
return $this->myquery;
}
}
?>
Block_User.php
<?php
include("ClassConnection.php");
$mcon=new connection();
$mcon->open_connection();

You can do that with fancy javascript which will move div box with output message into wherever you like.
But that's only dirty hack, not the proper way to code.
The proper way is to divide operation and display (at least, MVC is even better).
This way you can set some variable indicating name was changes and generate a page from template based on that variable (ie with success msg set on top of page if there is one).
Please don't make your own template engine. Use some existing ones instead (Savant is quite easy to learn).
Edit:
Ok, I won't give you ready-to-use code, instead I will tell you how to do it the quick-but-dirty way:
1) create a div in which you want your message to appear, place it wherever you want it to be and give it some id (unique in page scope) ie:
<div id="resultMsg"></div>
2) later in your php code: instead of printing div with a message, print some javascript which will fill your resultMsg container with a message:
echo '<script type="text/javascript">document.getElementById("resultMsg").innerHTML = "put your generated message here";</script>';
It's quick fix but don't get used to it. Instead learn how to do this the right way. You can start with https://github.com/phplucidframe/phplucidframe/wiki/Integration-of-Savant,-The-Simple-Template-System or use other templating system. It will save you many bigger problems than this one in future :)
