100分求jquery.pagination实例或解决当前分页问题
项目使用jquery.pagination，遇到了一些问题，求高人解决。
发个类似的实例也行。不甚感激。
分页陷入了死循环

我也遇到同样的问题。
7楼的是正解。
将 pagination.js 里的方法（这是pagination的构造方法，在最后一行代码会调用一下callback方法所以要注释掉它）：
// Extend jQuery
$.fn.pagination = function(maxentries, opts){
// Initialize options with default values
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,
renderer:"defaultRenderer",
callback:function(){return false;}
},opts||{});
var containers = this,
renderer, links, current_page;
/**
* This is the event handling function for the pagination links.
* @param {int} page_id The new page number
*/
function pageSelected(evt){
var links, current_page = $(evt.target).data('page_id');
containers.data('current_page', current_page);
links = renderer.getLinks(current_page, pageSelected);
containers.empty();
links.appendTo(containers);
var continuePropagation = opts.callback(current_page, containers);
if (!continuePropagation) {
if (evt.stopPropagation) {
evt.stopPropagation();
}
else {
evt.cancelBubble = true;
}
}
return continuePropagation;
}
current_page = opts.current_page;
containers.data('current_page', current_page);
// Create a sane value for maxentries and items_per_page
maxentries = (!maxentries || maxentries < 0)?1:maxentries;
opts.items_per_page = (!opts.items_per_page || opts.items_per_page < 0)?1:opts.items_per_page;
if(!$.PaginationRenderers[opts.renderer])
{
throw new ReferenceError("Pagination renderer '" + opts.renderer + "' was not found in jQuery.PaginationRenderers object.");
}
renderer = new $.PaginationRenderers[opts.renderer](maxentries, opts);
containers.each(function() {
// Attach control functions to the DOM element
this.selectPage = function(page_id){ pageSelected(page_id);}
this.prevPage = function(){
var current_page = containers.data('current_page');
if (current_page > 0) {
pageSelected(current_page - 1);
return true;
}
else {
return false;
}
}
this.nextPage = function(){
var current_page = containers.data('current_page');
if(current_page < numPages()-1) {
pageSelected(current_page+1);
return true;
}
else {
return false;
}
}
});
// When all initialisation is done, draw the links
links = renderer.getLinks(current_page, pageSelected);
containers.empty();
links.appendTo(containers);
// call callback function, comment the following code to avoid calling the callback method when initialize the pagination//opts.callback(current_page, containers);
}

为什么不用分页控件呢？？？
