[英]How to change the number of pagination buttons of the DataTables jQuery plugin
By default, DataTables
plugin shows 7 paging buttons (including the ellipses) like默认情况下,
DataTables
插件显示 7 个分页按钮(包括省略号),例如
Previous 1 2 3 4 5 ... 10 Next上一页1 2 3 4 5 ... 10下一页
I would like to be able to change this to a smaller number like我希望能够将其更改为较小的数字,例如
Previous 1 ... 10 Next上一页1 ... 10下一页
and I can't find this anywhere in the documentation.我在文档中的任何地方都找不到这个。
I found this plugin but it says that's deprecated and that the我找到了这个插件,但它说它已被弃用,并且
DataTables 1.10 has this ability built in.
DataTables 1.10 内置了此功能。
but it doesn't show where to change this.但它没有显示在哪里改变这一点。
I finally found it after fiddling with the DataTable
javascript object and the DataTables
' source code.在摆弄
DataTable
javascript 对象和DataTables
的源代码后,我终于找到了它。
You have to add this line (either before or after initialization) :您必须添加此行(在初始化之前或之后) :
$.fn.DataTable.ext.pager.numbers_length = 3;
Note that this will show up like请注意,这将显示为
Previous 1 ... 10 Next上一页1 ... 10下一页
and not并不是
Previous 1 2 ... 10 Next上一页1 2 ... 10下一页
so be sure to include the ellipses in the length number.所以一定要在长度数字中包含省略号。
Edit:编辑:
I saw some problems with this solution when advancing through the pages.在浏览页面时,我发现此解决方案存在一些问题。
I had to rewrite their _numbers
function like this:我不得不像这样重写他们的
_numbers
函数:
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:并用它向我自己的函数指出
DataTables
:
$.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.另外,我必须将他们的
_range
函数复制到我的main.js
文件中。
显然 DataTableJS 的理想最小值是:
$.fn.DataTable.ext.pager.numbers_length = 5;

Add the following after the script loaded加载脚本后添加以下内容
<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"] };
