How to pass page number to pageClick function in Jquery-Simple pagination

I am using jquery simplePagination.js in my application. I created a function name showProjectPage(pageNumber). It is used to show the particular page with the page number. I used the following code for doing pagination using SimplePagination.js

$(".paging").pagination({
    items: totalItmes,
    itemsOnPage: perPageItem,
    cssStyle: 'light-theme',
    currentPage : currentPageNumber,
    onPageClick : showProjectPage
});

I can call the function usning onPageClick : showProjectPage. How can I pass the pageNumber to this function?

Try this,

onPageClick : function(){
            showProjectPage(currentPageNumber)
          }

Full Code

$(".paging").pagination({
    items: totalItmes,
    itemsOnPage: perPageItem,
    cssStyle: 'light-theme',
    currentPage : currentPageNumber,        
    onPageClick : function(){
            showProjectPage(currentPageNumber)
          }
});
