发布时间:2019-07-14编辑:脚本学堂
本文介绍下,用Jquery实现无刷新分页的一个完整代码,有需要的朋友,参考下吧。

1、文件 jquery.pagination.js
 

复制代码 代码示例:

 jQuery.fn.pagination = function(maxentries, opts) {
     opts = jQuery.extend({
         items_per_page: 10,
         num_display_entries: 10,
         current_page: 0,
         num_edge_entries: 0,
         link_to: "#",
         prev_text: "Prev",
         next_text: "Next",
         ellipse_text: "...",
         prev_show_always: true,
         next_show_always: true,
         callback: function() { return false; }
     }, opts || {});

     return this.each(function() {
         /**
         * Calculate the maximum number of pages
         */
         function numPages() {
             return Math.ceil(maxentries / opts.items_per_page);
         }

         /**
         * Calculate start and end point of pagination links depending on
         * current_page and num_display_entries.
         * @return {Array}
         */
         function getInterval() {
             var ne_half = Math.ceil(opts.num_display_entries / 2);
             var np = numPages();
             var upper_limit = np - opts.num_display_entries;
             var start = current_page > ne_half ? Math.max(Math.min(current_page - ne_half, upper_limit), 0) : 0;
             var end = current_page > ne_half ? Math.min(current_page + ne_half, np) : Math.min(opts.num_display_entries, np);
             return [start, end];
         }

         /**
         * This is the event handling function for the pagination links.
         * @param {int} page_id The new page number
         */
         function pageSelected(page_id, evt) {
             current_page = page_id;
             drawLinks();
             var continuePropagation = opts.callback(page_id, panel);
             if (!continuePropagation) {

                     evt.stopPropagation();
                 }
                 else {

         * This function inserts the pagination links into the container element
         */

             var np = numPages();
             // This helper function returns a handler function that calls pageSelected with the right page_id
             var getClickHandler = function(page_id) {
                 return function(evt) { return pageSelected(page_id, evt); }
             }
             // Helper function for generating a single link (or a span tag if it'S the current page)
             var appendItem = function(page_id, appendopts) {
                 page_id = page_id < 0 ? 0 : (page_id < np ? page_id : np - 1); // Normalize page id to sane value
                 appendopts = jQuery.extend({ text: page_id + 1, classes: "current" }, appendopts || {});
                 if (page_id == current_page) {
                     var lnk = $("<span class='current'>" + (appendopts.text) + "</span>");
                 }

             }
         }

         // Extract current_page from options
         var current_page = opts.current_page;
         // Create a sane value for maxentries and items_per_page
         maxentries = (!maxentries || maxentries < 0) ? 1 : maxentries;
         opts.items_per_page = (!opts.items_per_page || opts.items_per_page < 0) ? 1 : opts.items_per_page;
         // Store DOM element for easy access from all inner functions
         var panel = jQuery(this);
         // Attach control functions to the DOM element
         this.selectPage = function(page_id) { pageSelected(page_id); }
         this.prevPage = function() {
