How Can I see Update info into my TextArea and Scrolling???

[Anirhudra]

I have a TextArea and there I want to write my tracefile info .... but I want
to see the scrolling automatically and to see the last line of my tracefile info
within this TextArea without scrolling.

Here is my HTML file ...

FORM name="TraceFile">
<TextArea Name = "commentbox" ROWS="8" COLS="70"></TextArea>


Here is my JavaScript function

function print_log(line) {
// Display the TraceFile info into the TextBox
document.LogFile.commentbox.value = document.TraceFile.commentbox.value + line + "\n";
}



Could you pls anybody give me the idea how I can I solve this problem?

You're not going to get the text area to scroll. It just doesn't happen. What you can do is either a) clear the text area out and replace the contents or b) prepend instead of appending the newest entry. The latter is probably better and would look like this:

function print_log(line) {        
// Display the TraceFile info into the TextBox
document.LogFile.commentbox.value = line + "\n" + document.TraceFile.commentbox.value;
}
 

Hope that helps.
