How to change the number of pagination buttons of the DataTables jQuery plugin
I finally found it after fiddling with the DataTable
javascript object and the DataTables
' source code.
You have to add this line (either before or after initialization):
$.fn.DataTable.ext.pager.numbers_length = 3;
Note that this will show up like
Previous 1 ... 10 Next
and not
Previous 1 2 ... 10 Next
so be sure to include the ellipses in the length number.
Edit:
I saw some problems with this solution when advancing through the pages.
I had to rewrite their _numbers
function like this:
function _numbers(page, pages) {
var
numbers = [],
buttons = 5, // added here the number of buttons
half = Math.floor(buttons / 2);
if(pages <= buttons) {
numbers = _range(0, pages);
} else if(page <= half) {
numbers = _range(0, buttons - 2);
numbers.push("ellipsis");
numbers.push(pages - 1);
} else if(page >= pages - 1 - half) {
numbers = _range(pages - (buttons - 2), pages);
numbers.splice(0, 0, "ellipsis");
numbers.splice(0, 0, 0);
} else {
numbers.push(page); // changed this from _range(page - 1, page + 2);
numbers.push("ellipsis");
numbers.push(pages - 1);
numbers.splice(0, 0, "ellipsis");
numbers.splice(0, 0, 0);
}
numbers.DT_el = "span";
return numbers;
}
And used this to point out DataTables
to my own function:
$.fn.DataTable.ext.pager.simple_numbers = function(page, pages) {
return ["previous", _numbers(page, pages), "next"];
};
Also, I had to copy their _range
function into my main.js
file.

Add the following after the script loaded
<script>
$.fn.DataTable.ext.pager.numbers_length = 3;
$.fn.DataTable.ext.pager.full_numbers_no_ellipses = function (e, r) { var a = [], n = $.fn.DataTable.ext.pager.numbers_length, t = Math.floor(n / 2), l = function (e, r) { var a; void 0 === r ? (r = 0, a = e) : (a = r, r = e); for (var n = [], t = r; t < a; t++)n.push(t); return n }; return (a = r <= n ? l(0, r) : e <= t ? l(0, n) : e >= r - 1 - t ? l(r - n, r) : l(e - t, e + t + 1)).DT_el = "span", ["first", "previous", a, "next", "last"] };
</script>
