How to disable checkbox if condition is true using jQuery?

I have tried to disable checkbox like

 var t8 =283.50;
 var t9 = 283.50;
        

 if (t8 == t9) {
   $('.checkBoxClass:input([value=' + t11 + ')').attr('disabled', true);
 }

Condition is working but the checkbox is not getting disabled.

trtoggle += 
    "<tr><td class='invoicedate_check'>" + t6 + 
    "</td><td class='invoiceno_check'>" + t7 + 
    "</td><td style='text-align: right;' class='invoiceamt_check'>" + t8 + 
    "</td><td  style='text-align: right;' class=''>" + t9 + 
    "</td><td  style='text-align: right;' class=''>" + balance + 
    "</td><td class='checkBoxtd" + t11 + 
    "'><input type='checkbox' class='checkBoxClass checkBoxClassse" + t11 + 
    "' id='checkbox"+t11+"' name='myTextEditBox[]' value='" + t11 + 
    "'/> Select</td></tr>";

$(".tableinvoice_proj").last().append(trtoggle);

Here is my full function code:

$('#projectname_add').on('change', function() {
        $(".projectname_add_TextBox").val($(".projectname_add option:selected").html());
          var projectname_add = $('.projectname_add').val();
          var getID_comp = $('#getID_comp').val();
          //alert(getID_comp)
          $('#tableproject').find('tbody').remove();
          $('#tableinvoice_proj').find('tbody').remove();
          $('#myprojdisplay_new').find('tbody').remove();
          $('#myprojdisplaylatest').find('tbody').remove();
          if(projectname_add !== "list_all_projects"){
        $.ajax({
            url: base_url + "index.php/welcome/list_a_projects_invoice/",
           // url: base_url + "index.php/welcome/invoice_allList/",
            type: "POST",
            data: {
                "id": projectname_add
            },
            success: function(data) {
                var new_data = JSON.parse(data);
                console.log(new_data)
                
                if(new_data == "No Records Found"){ //no invoice for this project
                     $('#myprojdisplay_new').hide();
                     $('#tableproject').hide();
                     $('#myprojdisplaylatest').hide();
                }else{
                    $('#myprojdisplay_new').show();
                    $('#myprojdisplaylatest').show();

       }
            }
                    $(".tableinvoice_proj").last().append(trtoggle);





                }
                
                

            }
        });
        
    
    }
})

The above is the code when dropdown option changed, two tables are displaying.one table for project details inside project details invoice html table will come.Here i need to disable the checkbox based on the if condition
