Finding it challenging to retrieve the dynamically generated data from the PHP-MYSQL combination through jQuery AJAX

The question's title doesn't provide much information. Let me explain what I'm trying to accomplish here. Using jQuery, I have an HTML form that sends an AJAX request to a PHP file. The PHP file successfully returns the required data back to AJAX, and I am able to view these values. However, I'm encountering an issue when attempting to retrieve the value of a single element using its attribute. This problem will become clearer once you review my jQuery code:

var temp_client_name;
$("#temp_client_name").on('click', 'li', function(){
    temp_client_id = $(this).attr('id');
    //temp_client_name = $("#"+temp_client_id).html();
    temp_client_name = $("li[id='+temp_client_id+']").html();
    $("#client_name").val(temp_client_name);
    console.log('temp_client_name ' + temp_client_name);
});

The problem lies specifically in line 5 (an alternative to line 4, which appears to achieve the same result - hence why I commented it out as a viable option). In line 3, I retrieve the ID of the HTML element whose value interests me, and this works correctly; I obtain the correct ID for the desired element. So where could I possibly be making a mistake?

Snippet: Get Value using jQuery

// Retrieve the value of a specific element's ID
temp_client_name = $("li[id='+temp_client_id+']").val();

If you wish to utilize the variable temp_client_id:

// Obtain the value of an element with the specified ID (temp_client_id)
temp_client_name = $("li[id='" + temp_client_id + "']").val();

However, I am uncertain about the purpose behind this approach since accessing an element by its id can be accomplished with the following:

// Fetch the value using the unique identifier (id)
value = $( "#id" ).val();

Make sure to wrap the + sign with double quotes (") when using it in this line of code:

temp_client_name = $("li[id='"+temp_client_id+"']").val();

However, an alternative approach would be to use the following line of code:

temp_client_name = $(this).val();

Rather than doing multiple steps like this:

temp_client_id = $(this).attr('id');
//temp_client_name = $("#"+temp_client_id).val();
temp_client_name = $("li[id='"+temp_client_id+"']").val();

There are a few errors in your code that need to be addressed.

The IDs of the elements should be unique.
The HTML tag <li></li> does not have a value attribute, so using val() here is not helpful.
The line
```
temp_client_name = $("li[id='+temp_client_id+']").val();
```
is not functioning correctly because the concatenation is incorrect. It should be written as
```
$('li[id='+your_variable_here+']').val();
```

var temp_client_name;
$(document).on('click', 'li', function(){
 temp_client_id = $(this).attr('data-id');
 temp_client_name = $('#'+temp_client_id).val();
 alert('temp_client_name ' + temp_client_name);
});
