Javascript search()

I need to find the position or existence of a “.” in a string.

I believe the “.” is a special character, therefore how would I search for a “.” in my string.

strFileName = new String(UploadForm.FileName.value)
regExp = “.”;
strExt = new String(Right(strFileName, 4))
result = strExt.search(regExp)
alert(strExt)
alert(result)

Note: The right(str, n) uses a function that mimics the behaviour of the same vbscript function.

@AdamGundryAug 13.2003 — You can use [url=http://devedge.netscape.com/library/manuals/2000/javascript/1.3/reference/string.html#1196895]indexOf[/url] instead, I believe:

result = strExt.indexOf('.');

Use the escape character, a backslash ( ) or Adam's method.
