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>

Hi Blessed7777,
One of the attempt is using xmlhttp object to verify the file existence based on specified file location.
http://www.w3schools.com/XML/xml_http.asp

Here is attempt



<script type="text/javascript">

var blnFound=false;//check the file existance
 

function notEmpty(){
 

        var myTextField = document.getElementById('TextBox1');

        if(myTextField.value != "") {

		

                var path = "\\\\server1.com\\users\\CkImgs\\" + myTextField.value + ".tif";

                CallFile(path);

		

		if(blnFound==false){

        		path = "\\\\server1.com\\users\\CkImgs\\" + myTextField.value + ".pdf";

			CallFile(path);

		}

	}       

        

}
 

function CallFile(strLocation){
 

//inital xmlhttp

var xmlhttp=false;

 try {

  xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");

 } catch (e) {

  try {

   xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

  } catch (E) {

   xmlhttp = false;

  }

 }
 

if (!xmlhttp && typeof XMLHttpRequest!='undefined') {

	try {

		xmlhttp = new XMLHttpRequest();

	} catch (e) {

		xmlhttp=false;

	}

}

if (!xmlhttp && window.createRequest) {

	try {

		xmlhttp = window.createRequest();

	} catch (e) {

		xmlhttp=false;

	}

}
 

 xmlhttp.open("GET", strLocation,true);
 

 xmlhttp.onreadystatechange=function() {

  if (xmlhttp.readyState==4) {

     if (xmlhttp.status==200)  {

       blnFound=true;

       window.open(strLocation,'mywindow2')//open your document here

     }else if (xmlhttp.status==404) {blnFound=false;//file not exist}

   }

 }

 xmlhttp.send(null)
 

}

</script>

<input type=text id="TextBox1" value="testFile"/>

<script>
