Display the javascript code of the html page in textarea

I want the html page written in textarea to be displayed as html
I know that tools such as htmledit can't be used. I only need simple display.
1st Floor
You can use document. write ()
If you want to edit it, I think you may still need tools like htmledit. I am studying fckeditor, which has a few types and has fewer functions. Hey, my personal opinion, hope it will be useful to you.
2nd floor
<Textarea id = tx1> </textarea>
<Input type = button value = "show" onclick = "test ();")>
<Script>
Function test ()
{
X = window. open ("about: blank ");
X.doc ument. write (tx1.value );
}
</Script>
Third floor
Display in multi-line text box
Function Deal (fString)
FString = replace (fString, ">", "> ")
FString = replace (fString, "<", "<")
FString = Replace (fString, "", chr (32 ))
FString = Replace (fString, "", chr (34 ))
FString = Replace (fString, "'", chr (39 ))
FString = Replace (fString, "", CHR (13 ))
FString = Replace (fString, "</P> <P>", CHR (10) & CHR (10 ))
FString = Replace (fString, "<BR>", CHR (10 ))
Deal = fString
End function
This function can be used
