Javascript Removing Punctuation Question

Why is it brain surgery removing periods, question marks and exclamation points from a string in Javascript?


So far I've gotten to this point:

temp = temp.replace (/,/g, "");


Any help would be greatly appreciated, thanks!

I figured it out, thanks for reviewing:


temp = temp.replace (/[.,?!\s,]/g, " ");

I figured it out, thanks for reviewing:

temp = temp.replace (/[.,?!\s,]/g, " ");

No, you must escape the Meta characters:-

temp = temp.replace (/[\.\,\?!\s]/g, ""); // replace by nothing, i.e delete

. in a regex means any character. If you want a literal period (dot) you must escape it so \.

The set of characters that are literal (i.e. that do not have special meaning) is much larger in a character set than it is in a pattern. None of .,?! have any special meaning in a character set.
