Hi,

I am trying to make a slide show of images with javascript. I don't want the page to refresh so I call document.write() every time the next and previous buttons is clicked. Onclick, I call a funcion that ajust the current frame number and call updte(currentFrame) that does document.write() and write the entire page.

When the page is first loaded is calls

CODE

updte(1);

CODE

function updte(f)
{
document.write("<body bgcolor = '#000000' style='color:#ffffff' ><div align = 'center'><img src ='logo.jpg'/> <input type = 'button' value = 'Hide Descriptions' onclick = 'off()'/><input type = 'button' name = 'backward' value = '< previous frame' onClick = 'goBack()'><input onClick = 'goForward()' type = 'button' name = 'fowards' value = ' next frame >'> <table border='0' align = 'center'><tr><td width='241' height='261' rowspan='2' valign = 'Top'>Brief description of action: "+actionArr[f]+" Dialogue / Voiceover: "+ dialogueArr[f]+" Setting: "+setArr[f]+" Shot size: "+sizeArr[f]+"</td><td width='332' height='67' valign = 'Top' align = 'center'>Number: Time: "+TimeArr[f]+"</td> <td width='252' rowspan='2' valign = 'Top'>Camera movement: "+camMoveArr[f]+" Camera Angle: "+camAngArr[f]+" Lighting: "+lightArr[f]+" Props: "+ propArr[f]+"Costume: "+cosArr[f]+" Music: "+musicArr[f]+" Sound FX " +soundArr[f]+"</td></tr><tr><td height=296 width='380' valign = 'Top'><img name = 'change' src = '" + imageArr[f]+ " ' width='330' height='271' /></td> </tr></table></div>");
}

CODE

The problem is that I randomly get a goForward not defined error (mostly on the third or second click, but never on the first.)

Please Help!

That sounds like a difficult solution. Why not just change the image SCR value instead?

BTW if you want to write XHTML syntax, document.write is not allowed.

I get errors that the image arrays(?) actionArr etc are not defined.

I used

CODE

document.images["change"].src = array[i]

but I get exactly the same errors. The other problem is that the text around it has to change as well and I thougth it would just be easier to change everything in one call.

Is there an alternative to document.write?

Thats because you don't have all my code.

CODE

var TimeArr = new Array(30);
   var actionArr = new Array(30);
   var dialogueArr = new Array(30);
   var sizeArr = new Array(30);
   var camMoveArr = new Array(30);
   var camAngArr = new Array(30);
   var lightArr = new Array(30);
   var setArr = new Array(30);
   var propArr = new Array(30);
   var cosArr = new Array(30);
   var musicArr = new Array(30);
   var soundArr = new Array(30);
   var imageArr = new Array(30);
   var numFrames;
   var frame = 1;

You might use innerHTML, or the DOM.
