Testing for element type

   while (Column <= Columns)
    	{
				var DataString = Title[Column] + "[" + Record + "]";
				alert(DataString);
				alert(document.getElementById(Title[Column]));
        switch (document.getElementById(Title[Column]))
					{
						case "[object HTMLDivElement]":
							alert("[object HTMLDivElement]");
							document.getElementById(Title[Column]).innerHTML = DataString;
						break;
							
						case "[object HTMLInputElement]":
							alert("[object HTMLDivElement]");
							document.getElementById(Title[Column]).value = DataString;
						break;

						case "[object HTMLTextAreaElement]":
							alert("[object HTMLDivElement]");
							document.getElementById(Title[Column]).innerHTML = DataString;
						break;
					}	

Code (markup):

But I get no match although the alert value is what I expect.

 

I think you should give full example
