Is it possible to write a bash function to change directory by passing the name of a directory variable?

I want write a function which changes the working directory by passing the name of a directory variable which has already been established like :

foo () { cd $"$1"
}

However when I try , for example, foo links I get -bash: cd: links: No such file or directory

Is it possible to do this ?

You can use variable indirection:

foo () { cd "${!1}"
}
dir=/mnt
foo dir
pwd # /mnt
