It is nice to show loading behavior to user and let user no something is happening which take some time and avoid touching UI.

In bootstrap it is very simply task.

I think it might help you

$(this).button(‘loading’) shows loading text in button. we tell this to bootstrap by using data-loading-text=”Loading…” 

When finishing our long runing logic we can call

$(this).button(‘reset’);

This will bring button to original state.
