Opening pdf and tif using javascript function in ASP.net 3.5

Hi,

I am trying to write code that will open images with pdf and tif extensions.  The idea is for the code to look for a tif file with the name.  If it doesn't find it then it should look for a pdf.  If both are present it should open them both.  I can get the tif and pdf codes to work separately but not together.  Any assistance you all could provide would be great!

Thanks

<script type="text/javascript">
function notEmpty(){
	var myTextField = document.getElementById('TextBox1');
	if(myTextField.value != "") {
		var path = "\\\\server1.com\\users\\CkImgs\\" + myTextField.value + ".tif";
		window.open(path,'mywindow2')
//		var path = "\\\\server1.com\\users\\CkImgs\\" + myTextField.value + ".jpg";
//		window.open(path,'mywindow')
	}	
	
}
</script>
