Javascript正则表达式，用于删除字符串末尾的字符

Question

I have a couple strings like:

net_weight_(lbs)
net_height_(inches)

I need a regular expression that will remove the _(x) from the end of the string. So in my two examples, I would be left with:

net_weight
net_height

Any help would be greatly appreciated

If you'd prefer not to use regular expressions you can use lastIndexOf('_') and the get the substring up to that index.

s = s.substr(0, s.lastIndexOf('_'));
