Replace Carrot Character

[shift314]

I'm writing a javascript calculator and need to replace the '^' character. Javascript does not seem to recognize this character correctly in a string.

var test="abc^d";
var searchstring="c"
alert(test.search(searchstring));

The above code correctly displays 2 when I change the c to ^, I get 0, not even -1. I get zero regardless of the position of ^. If I search for "c^" I get -1.

Any help is appreciated.

You need to escape the ^, as it has a special meaning in regular expressions (which is what we're dealing with here in the search method).

If you use:

var searchstring = "\\^";

then all works as expected.

Hope this helps,

^ is spelt as caret: not carrot

Says the man who used a colon when a comma would have been better.
