    exif displayed for first image only?

    Hi all,

    I have a page that displays the exif info of an image.
    Unfortunately it only works for the first image.

    After 2 seconds you should see 2 lines:
    Wait 5 seconds, then click me!
    GPSLatitudetag: 51,48,7.572668393782384

    Then after clicking the link this line should be added:
    GPSLatitudetag: 51,48,7.495423197492163

    However I get only this:
    GPSLatitudetag:

    No exif info for the second image.
    Why?

    You can download a copy for local testing here.

    Code:
    <html>
    <head>
    <script type="text/javascript" src="jquery-1.3.2.min.js"></script>
    <script type="text/javascript" src="jquery.exif.js"></script>
    
    </head>
    <body>
    <div id="imagediv"></div>
    <div id="linkdiv"></div>
    
    <script language="javascript">
    document.getElementById('imagediv').innerHTML ="\<img src=\"001.jpg\" width=\"450px\" height=\"225\" id=\"imgA\" exif=\"true\" \/\>";
    document.getElementById('linkdiv').innerHTML ="\<a href=\"#\" onclick=\"changeImg('002.jpg'); return false;\">Wait 5 seconds, then click me!\<\/a\>";
    
    function changeImg(newimage){
    	document.getElementById('imagediv').innerHTML ="<img src=\""+newimage+"\" width=\"450px\" height=\"225\" id=\"imgA\" exif=\"true\" \/\>";
    	getexif();
    } // end changeImg
    
    function getexif(){
    	$("#imgA").load(function() { 
    		setTimeout(function(){
    			GPSLatitudetag = $("#imgA").exif("GPSLatitude");
    			document.getElementById('linkdiv').innerHTML +="<br>GPSLatitudetag: "+GPSLatitudetag+"";
    	}, 2000); // end Timeout
    	}); // end load
    } // end getexif
    
    getexif();
    
    </script>
    </body>
    </html>

    You are passing the same ID to getexif. An ID must be unique to the document.
    At least 98% of internet users' DNA is identical to that of chimpanzees

    Do you mean "imgA"?

    I made it unique by naming it after a part of the filename.

    Still doesn't work: test2.html

    Code:
    <html>
    <head>
    <script type="text/javascript" src="jquery-1.3.2.min.js"></script>
    <script type="text/javascript" src="jquery.exif.js"></script>
    
    </head>
    <body>
    <div id="imagediv"></div>
    <div id="linkdiv"></div>
    
    <script language="javascript">
    startimage="001.jpg";
    shortfilename= startimage.substring((startimage.indexOf('.jpg')-3), startimage.indexOf('.jpg'));
    alert("img id: "+shortfilename);
    
    document.getElementById('imagediv').innerHTML ="\<img src=\""+startimage+"\" width=\"450px\" height=\"225\" id=\""+shortfilename+"\" exif=\"true\" \/\>";
    document.getElementById('linkdiv').innerHTML +="\<a href=\"#\" onclick=\"changeImg('002.jpg'); return false;\">Wait 5 seconds, then click me!\<\/a\>"
    
    function changeImg(newimage){
    newshortfilename= newimage.substring((newimage.indexOf('.jpg')-3), newimage.indexOf('.jpg'));
    alert("img id: "+newshortfilename);
    	document.getElementById('imagediv').innerHTML ="<img src=\""+newimage+"\" width=\"450px\" height=\"225\" id=\""+newshortfilename+"\" exif=\"true\" \/\>";
    	getexif(newshortfilename);
    } // end changeImg
    
    function getexif(id){
    	$("#"+id).load(function() { 
    		setTimeout(function(){
    			GPSLatitudetag = $("#"+id).exif("GPSLatitude");
    			document.getElementById('linkdiv').innerHTML +="<br>GPSLatitudetag: "+GPSLatitudetag;
    	}, 2000); // end Timeout
    	}); // end load
    } // end getexif
    
    getexif(shortfilename);
    
    </script>
    </body>
    </html>

    With the help of a friend I managed to get one step closer to a working solution.

    Now it shows the data twice. But its the data of the first image.
    How to make it show the data of the second image?

    Thanks,
    Jan

    P.S.:
    This code works with the zip provided.

    Code:
    <html>
    <head>
    <script type="text/javascript" src="jquery-1.3.2.min.js"></script>
    <script type="text/javascript" src="jquery.exif.js"></script>
    
    </head>
    <body>
    
    <div id="imagediv">
    <img src="001.jpg" width="450px" height="225" id="imgA" exif="true" onload="showexif()" \>
    <p><a href="#" onclick="changeImg('002.jpg');">Wait 5 seconds, then click me!</a></p>
    </div>
    <p id="linkdiv"></p>
    
    <script language="javascript">
    
    function changeImg(newimage){
    	document.getElementById('imgA').src = newimage ;
    } // end changeImg
    
    function showexif() {
    	setTimeout(function(){
    		GPSLatitudetag = $("#imgA").exif("GPSLatitude");
    		document.getElementById('linkdiv').innerHTML += "<br>GPSLatitudetag: "+GPSLatitudetag;
    	}, 2000); // end Timeout
    } // end showexif
    
    
    </script>
    </body>
    </html>
