Javascript and reg exp

[Wuoshi]

I got a Javascript which is receiving a url, for example product1_product2_product3_.html. When the url is received I want to split it in to three variables, var1 which is product1, var2 which is product2 and so on.

I figure this can be solved by using regular expressions? Anybody know how?

Thanks in advance for any answers.

you don't have to use regular expressions, if it's always split by a _, it would be much easier to use split. something like this:

var str = "product1_product2_product3_.html";
str = str.substr(0, -5);
split = str.split("_");

now product1 is stored in split[0], product2 is in split[1], product3 is in split[2], etc.

however, note that the negative string length for substr doesn't work in IE (as far as i know), so you might want to consider trying to switch this to PHP.
