Dynamically populate a textarea from a text file?
- Thread starter ChillAPAC
- Start date
Here's something that works for me with IE and Opera.
Basically, load text file into hidden iframe. Read contents of hidden iframe and load into textarea. NOTE that iframe contents seem to automatically get <PRE></PRE> tags put around it, which have to be removed.
'hope this helps.

Code:
<html>
<head>
<script>
function getIt()
{
var text = document.frames[0].document.body.innerHTML;
//remove <PRE></PRE> tags
text = text.substring(("<PRE>").length);
text = text.substring(0, text.indexOf("</PRE>"));
myText.value = text;
}//end getIt()
</script>
</head>
<body onload='getIt();'>
<textarea id='myText' rows='10' cols='60'></textarea>
<iframe src='text.txt' width='0' height='0'></iframe>
</body>
</html>'hope this helps.

It is possible to create a textarea in html. It is also possible to prefill that text area with text. Html however cannot help you with loading of a file or providing logic to determine whether file exists or not. If file is on the server, then your preferred choice of server side scripting will help. If it is client side, then I guess you can work with javascript. Both solutions fall out of scope of this forum.
