JQuery Datatables pagination: show 2 previous and 2 next numbers from current page

Question

On JQuery Datatable I have following pagination style.

|Previous|1| ....|4|5|6|...|13|Next|

But I want something like this.

|Previous|1| ...|3|4|5|6|7|...|13|Next|

In both cases, 5 is the current page. Is there any way we can achieve that? Many Thanks.

Answer 1

I found the solution from a similar type of StackOverflow question.

DataTables change number of pagination buttons

And the solution for above question is to load datatable and add the following line of code as a requirement.

<script type="text/javascript">
    $.fn.DataTable.ext.pager.numbers_length = 9;
    // number need to be odd number; default is 7
</script>

Like this:

var count_of_pages=13;

function set_pages(_page){
   $('#test').empty();
   if(_page==1){
   	     //start no act
   	   $('#test').append('<div class="white-btn-noactive">Previous</div>');
   }else{
   	     //start act
   	   $('#test').append('<div class="white-btn" onclick="alert(\'start page '+(_page-1)+'\');set_pages('+(_page-1)+');">Previous</div>');
   }
   if(_page>3){
        //1
      $('#test').append('<div class="white-btn" onclick="alert(\'start page '+1+'\');set_pages(1);">'+1+'</div>');
       //.....
      $('#test').append('<div style="display:inline-block;">...</div>');
   }
   for(var i = 1; i < count_of_pages+1; i++) {
   	     if(((i-2)==_page)||((i-1)==_page)||(i==_page)||((i+1)==_page)||((i+2)==_page)){
   	  	     if(i==_page){
   	  	     	$('#test').append('<div class="white-btn-active">'+i+'</div>');
   	  	     }else{
   	  	     	$('#test').append('<div class="white-btn" onclick="alert(\'start page '+i+'\');set_pages('+i+')">'+i+'</div>');
   	  	     }
   	     }
   	  }
   if(_page<count_of_pages-3){
        ///....
        $('#test').append('<div style="display:inline-block;">...</div>');
        //count_of_pages
        $('#test').append('<div class="white-btn" onclick="alert(\'start page '+count_of_pages+'\');set_pages('+count_of_pages+');">'+count_of_pages+'</div>');
   }
   if(_page==count_of_pages){
   	   //end no act
   	  $('#test').append('<div class="white-btn-noactive">Next</div>');
   }else{
   	   //end act
   	  $('#test').append('<div class="white-btn" onclick="alert(\'start page '+(_page+1)+'\');set_pages('+(_page+1)+');">Next</div>');
   }

}

set_pages(6);

.white-btn{
  	display:inline-block;
  	margin:1px;
  	padding:2px;
  	padding-left:6px;
  	padding-right:6px;
    border-style:solid;
    border-width:2px;
    border-color:gray;
    color:gray;
    border-radius:4px;
    font-weight:bold;
    cursor:pointer;
  }
  .white-btn:hover{
  	border-color:black;
  	color:black;
  }
  .white-btn-active{
  	display:inline-block;
  	margin:1px;
  	padding:2px;
  	padding-left:6px;
  	padding-right:6px;
    border-style:solid;
    border-width:2px;
    border-color:red;
    color:red;
    border-radius:4px;
    font-weight:bold;
  }
  .white-btn-noactive{
  	display:inline-block;
