Preserved Topic: can't see what's wrong!

<script language="JavaScript">

<!--

  str = new String('filename.ext');

  alert(str.replace('\.', '_'));

//-->

</script>

IE's output: filename_ext
NS's output: _ilename.ext

any ideas?! i just to replace the dot with an underscore.

well, i did try this:

str = new String('filename.ext');  

if (document.layers)

  str = str.replace('\[b]\[/b].', '_')

else

  str = str.replace('\.', '_');

alert(str);

but that can't be the correct way!?! even String.replace() must be crossbrowser compatible?!

<script language="JavaScript">
<!--
str = new String('filename.ext');
alert(str.replace(/\./, '_'));
//-->
</script>

Enjoy!

Thanks.
