Can you avoid repetition in cases like this?

Question

I try to avoid repetition in my code as much as possible.

I know you can turn this:

variable = variable+2

into this

variable += 2

but how can I avoid repetition here? Surely there is a way...

this.className = this.className.replace("classname","")

Well, you can always roll a function that does the job. Then you don't have to write things twice each time. — pimvdb, Mar 10 '12 at 18:33

Unfortunately the answer is no, there is no shorthand for that type of statement.

Make a function to do what you are wanting? As far as a += I'm not aware of a way to overload the operators in javascript... see

If you can use JQuery you can call

$(this).removeClass('classname');

Or indeed in modern browsers `this.classList.remove('classname')` - either way is more reliable than a string replace! – bobince Mar 10 '12 at 18:46
@bobince This is exactly what I was looking for! Thanks man! Too bad I can't mark this as the chosen answer. – william malo Mar 10 '12 at 20:53
