If by that you mean how many \n characters, you can do this:<br />
<br />
var lines = document.nameOfYourForm.na<wbr />meOfYourTe<wbr />xtarea.val<wbr />ue.split(&quot;<wbr />\n&quot;).lengt<wbr />h;<br />
alert(lines);
</div>


If by that you mean how many \n characters, you can do this:

var lines = document.nameOfYourForm.nameOfYourTextarea.value.split("\n").length;
alert(lines);

<div>
Is there also a way to count lines where the text was automatically wrapped? My textarea's wrap attribute is set to 'physical', and I'm using IE 6.

<div>
assuming no \n characters:<br />
<br />
var lines = Math.round( document.nameOfYourForm.na<wbr />meOfYourTe<wbr />xtarea.val<wbr />ue.length / (1*document.nameOfYourForm<wbr />.nameOfYou<wbr />rTextarea.<wbr />cols) );
</div>


assuming no \n characters:

var lines = Math.round( document.nameOfYourForm.nameOfYourTextarea.value.length / (1*document.nameOfYourForm.nameOfYourTextarea.cols) );

<div>
I guess IE 6 does not insert \n characters at wrapping points no matter what the wrap attribute is set to. Is that true? I have tried using both 'hard' and 'physical' for the wrap attribute on my textarea and IE still never seems to put the \n's at the wrapping points. That issue has been bugging me because it would be very helpful in solving this problem.

Yes, I have combined both of the above approaches. It works, but it's not 100% accurate. But I guess it's the best I'll be able to do. Thanks for your help.
