我有一个功能分页我建立但我现在有一个问题，返回的数据量使分页大。我已经阅读了很多关于这个问题的帖子，并没有找到任何与我认为我需要的相近的东西。我正在寻找我的分页栏来限制页面。 Prev 1 2 3 4 5 6 . . . 11 Next Prev 1 . . . 6 7 8 9 10 11 Next
$(function() { //Manage Users Table and Search form JS Start
//loads table page 1 upon loading page.
load_table(1);

debug: true
}); */

load_table(1);
});
//global var for the clicking of pages and prev and next buttons.
var page = 1;
