Dear Friends,

I designed the textboxes and below html table..The values add dynamically to html table from text box.
My problem is: when i need to add already existing value in table, i need popup "Already Exist"

What I have tried:

$(".add-row").click(function(){
           var invno = $(".addInvNo").val();
           var invdate = $(".addInvDate").val();   
           var rowCount = $('#tblInvoices tr').length;
                 
          if(rowCount>1){
                   $("#tblInvoices").find(".tdinvno").each(function(){
                   if($(this).html()==invno){
                       alert("Invoice Already Exist");         
                   }  
                  else {
                        var markup = "<tr class='addvalues'><td align='center'></td><td class='tdinvno'>" + invno + "</td><td>" + invdate + "</td><td><input type='button' class='del-row' value='Delete' onclick='deleteRow(this)'></td></tr>";
                        $("#tblInvoices").append(markup);                
                  }
             
                 });  
        } 
        else if(rowCount<=1)
        {
        var markup = "<tr class='addvalues'><td align='center'></td><td class='tdinvno'>" + invno + "</td><td>" + invdate + "</td><td><input type='button' class='del-row' value='Delete' onclick='deleteRow(this)'></td></tr>";
                        $("#tblInvoices").append(markup);    
                       
        }    
          
        });

                var isContains = false;
                for (var i = 0; i < tds.length; i++) {
                    var td = tds[i];
                    if (td.innerText == invno) {
                        isContains = true;
                        break;
                    }
                }
                if (isContains) {
                    alert("Invoice Already Exist");
                    return;
                }
