Hello Shingo, 

In which cases/context would you like to enable or disable buttons? 

By not using JS, you can use the properties of OS and control it using the Enable property by using a Variable. 

Using JS, you can check these cases already posted before on the forum. Note, if this does not satisfy your question, I would suggest you search on the forum, a bunch of similar questions were already solved:)
