Remove first character with jQuery

Question

How would I go about removing the first character from this.className in the below line? The first variable will be _ and then a number. I just want the number to be assigned to className.

className = this.className; 

Furthermore I am changing "$('.inter').html(window[link[className]]);" to use an array instead of the className variable. Is the below code the correct way to use an array with the index as a variable?

$('.inter').html(window[link[className]]);

No need to use jQuery for that, just plain ol' javascript using .substring

var trimmed = this.className.substring(1);
