Error: unterminated parenthetical in RegExp

[gypsy3001]

Today, I was trying to construct a regular express in JavaScript. But
I kept getting the "Error: unterminated parenthetical" message.

I want to do something like this:

keyCombo = "";
pattern = new RegExp (keyCombo);
str = string.replace (pattern, "frown");

So, first thing I fixed is ":\(" . . . But I still get the same error!
I've also tried ":\\\\(". And that didn't work. Please help and give
me a hint. Thanks.

I want to do something like this:

keyCombo = "";
pattern = new RegExp (keyCombo);
str = string.replace (pattern, "frown");

Ok, I figured it out. It has to be surrounded by brackets to be
recognized as a character:

":[\(]"

Now I'm having another problem. "<3" isn't being recognized. It
doesn't error out. But none of the permutations work: "\<3", "[<]3",
and "[\<]3".

Quite weird . . . . there are so many exceptions to regular
expression. *sigh*

Why are you going through strings to get a RegExp?
Try RegExp literals:

pattern=/:\(/;

What do you mean by "none of the permutations *work*"?

var pattern=/<3/;
alert("abc<3def".replace(pattern," "));
