Some JS functions return empty string as 'null' value. So there is no
empty string. But this operation  Code: Pascal
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i if
StringValue = 'null' generate JS code like this Code: Javascript
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i if
StringValue === ""
This is working example:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
StringValue : String;begin  StringValue :=
window.localStorage.getItem('MeData');  if isNull(StringValue) then
begin    Writeln('empty');  end;     
This is not working:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
StringValue : String;begin  StringValue :=
window.localStorage.getItem('MeData');  if StringValue  = '' then
begin    Writeln('empty');  end;
