Answer 1

$("#testResult").html("<br/><br/>") and $("#testResult").html("<p>" + htm + "</p>") will overwrite contents of your "testResult" DIV. So, replace this

$('#testResult ').append(string1);
      $("#testResult").html("<br/><br/>");
      $("#testResult").html("<p>" + htm + "</p>");   
}

with

$('#testResult ').append(string1);
      $("#testResult").append("<br/><br/>");
      $("#testResult").append("<p>" + htm + "</p>");   
}

.append() : Will add or append extra strings to the existing contents of the DIV where as

.html() : Will removes or overwrite the existing contents of the DIV with newer one.

This is the main difference between .append() and .html() .

Answer 2

edit this part

   $("#testResult").append("<br/><br/>");
  Remove this part-->
  $("#testResult").html("<p>" + htm + "</p>");   

htm is empty string, as you never concatenate any string to it
