How to show the block when other blocks are hidden?

Hello,
There is such a problem - have a number of blocks with event on the wedge on them - if they click they are given the property display: none. The problem is that you need to show another div ( previously hidden in css ) when the container has all the blocks are hidden.
That is, we push the blocks in turns, one by one, they disappear as soon as the last block disappears when the desired unit.
Please tell me how it is possible to implement using JQuery, JavaScript
Thanks in advance
