Why the h*** this simple code does not work in IE?

[Fabri]

I would like to "join lines" in a textarea.
================================================
var el = document.getElementById("textarea");
oldText = el.value;
newText = oldText.replace("\n", "");
el.value = newText;
================================================

This extremely simple code works awesome in FF but noway in IE.

Also no errors in IE.

If I add:

================================================
var el = document.getElementById("textarea");
oldText = el.value;
newText = oldText.replace("\n", "");
alert(oldText);
alert(newText);
el.value = newText;
================================================
i can see that oldText and newText are the same.

The strange thing is that If I try:

alert(el.value.indexOf("\n")) it returns me the correct position.

Any help?

Regards.

The problem is probably the different ways line breaks are encoded on
different platforms so try a regular expression
oldText.replace(/\r|\n|\r\n/, "")

Martin, it doesn't work :-(.

Thank you anyway.

I don't understand.

All contiguous whitespace characters will be replaced by a single
space character.

Any help?

I hope so :-)

Sorry, forgot the g flag
oldText.replace(/\r|\n|\r\n/g, "")

Thx Martin and Rob, googling I found this other solution:

el.value = escape(el.value);
for (i=0;i<el.value.length;i++){
el.value = el.value.replace("%0D%0A", "");
}
el.value = unescape(el.value);

Bye :-)

and ...
newText = oldText.replace("\\n"," ");
by chance ?

but anyway ...
I think only 1st '\n' will be replace

if nothing work, try :

el.style.whiteSpace = 'nowrap';
(if return cariages are realy written that would no more work)

That may work, but the logic is absurd! It will loop through the
string as many times are there are characters - there may only be one
character to replace in 10,000.

And what is the point of escape/unescape? Please use either mine or
Martin's suggestion and save a zillion clock cycles - if for no other
reason that to save yourself a lot of typing.
