I want to load image dynamically from database in popup form

how to receive or integred databending in JS script with laravel8 ?

<script type="text/javascript">
function getValues(){
document.getElementById('txt1').value=imageName; /*imageName=toto.jpg*/
var path = '{{asset(storage/images/imageName)}}'  ; 
document.getElementById('img').src=path ;
}
</script>

>> In HTML <<
<input type="text" name="txt1"  id="txt1" /> 
<img src="default.jpg" name="img" id="img" >


>> ERROR <<
<pre>Use of undefined constant storage - assumed 'storage' (this will throw an Error in a future version of PHP) (View: C:\xampp\htdocs\Ecommerce-Front\resources\views\popup.blade.php)

let imageSrc = '\assets\images\graph.jpeg'

var imageId1 = workbook.addImage(

    filename: imageSrc,
    extension: 'jpeg',
  });

workbook.xlsx.writeBuffer().then((data) => {
  let blob = new Blob([data], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' });
  fs.saveAs(blob, 'Random Number Generator.xlsx');
});

After the file is played, you need to load a new file and start playback.

According to my plan, I did this:

the file "au.js"

function replay()
{
	var aud = document.getElementById("audio_label");
	aud.src = "cap.wav?cb=" + new Date().getTime();
	aud.load();
	aud.play();
}

function hproc(e)
{
	replay();
}

var x = document.getElementById("audio_label");
x.addEventListener('ended',hproc,false);

the "index.html"

<pre><script src="au.js"></script>
<body>
<audio id="audio_label" autoplay controls src="cap.wav"
type="audio/wav"></audio>

Overview: 
COVID-19 cases have been increased in the last period. As a result, Ministry of Health has 
decided to make a simple application to keep track of all citizens and their vaccination status.
In this TMA, it is required to help the Ministry implement the required application.
Requirements:
After a quick meeting with the employee in charge, you got the following information:
 It is required to store the whole data in one collection 
 Each citizen has a unique civil ID number (national number), name and other attributes (add 
at least 2 attributes from your choice). In addition, it is required to store information about 
all doses taken by the citizen.
 For each dose, the following information should be stored: manufacturer, when and where 
has been taken, and information about the health professional who gave it.
 Each health professional has a unique civil ID number, name, and it is required to store 
his/her experience (in years).
Moreover, you have been informed that the following operations happen frequently:
 Adding a new citizen to the list
 Adding a new dose to a specified citizen
 Retrieving number of fully vaccinated persons (who toke at least 2 doses)
 Saving all the data into a text file after sorting them according to Civil ID.
Analysis:
Q1: There are common attributes and methods between citizen and health professional. What 
is the best choice for designing and writing the codes of these two classes? Explain your 
answer.
Q2: Draw a simple class diagram showing only relationships between the classes.
Implementation:
After analysing the given requirements, implement the required application:
 with Object Oriented Programming style
 following the rules of good programming style (e.g. adding comments, etc.)
 using only the material covered in M251 (and its prerequisites)
Hints:
 For each class, it is required to implement constructors, setters, getters, toString() method,
and any other necessary method
3
 If the user tries to do an operation that could violate the state of objects, the operation 
should be ignored and the application should display an error message (e.g. adding a citizen
twice to the list, etc.)
 Checking equality of any 2 objects should be done via the equals() method
 There is a class that will do the main job of the application as follows:
o It has one collection to store the whole data (all citizens)
o It has static methods, one for each operation happens frequently
o When you add a citizen to the list, a message should be displayed to the user to explain 
the status of the operation (i.e. if it was successful or not)
Testing:
After implementing the required classes, design and implement a testing class to test them as 
follows:
 Add at least 7 citizens to the collection that stores the whole data
 Add 1, 2 and 3 doses to different citizens and keep some citizens unvaccinated
 Try to violate the state of the objects and show that your code prevents all violations.
 Show that the other operations that happen frequently are working fine
 At the end, the whole data should be saved into a text file and this file should be saved 
automatically inside the folder contains your Java project
