Javascript Invalid Quantifier using search

Question

I'm using JavaScript's .search() function and I have this code:

var temp_cc_number = "4111 1111 1111 1111";
var checker = "****";
alert(temp_cc_number.search(checker));

I'm getting this error:

"Invalid quantifier"

What do you think this is? Any help would be greatly appreciated and rewarded!

Thanks! :)

The * is a zero or more quantifier, therefore if you're trying to match literal * you need to escape it with the \. Or maybe a slightly better way: search(/\*{4}/). The {4} denotes a match count, in this case it matches the \* 4 times. You can also specify minimum and maximum ranges {M:N}, M being the minimum and N the maximum.
