内容介绍
/* * jQuery pager plugin * Version 1.0 (12/22/2008) * @requires jQuery v1.2.6 or later * * Example at: http://jonpauldavies.github.com/JQuery/Pager/PagerDemo.html * * Copyright (c) 2008-2009 Jon Paul Davies * Dual licensed under the MIT and GPL licenses: * http://www.opensource.org/licenses/mit-license.php * http://www.gnu.org/licenses/gpl.html * * Read the related blog post and contact the author at http://www.j-dee.com/2008/12/22/jquery-pager-plugin/ * * This version is far from perfect and doesn't manage it's own state, therefore contributions are more than welcome! * * Usage: .pager({ pagenumber: 1, pagecount: 15, buttonClickCallback: PagerClickTest }); * * Where pagenumber is the visible page number * pagecount is the total number of pages to display * buttonClickCallback is the method to fire when a pager button is clicked. * * buttonClickCallback signiture is PagerClickTest = function(pageclickednumber) * Where pageclickednumber is the number of the page clicked in the control. * * The included Pager.CSS file is a dependancy but can obviously tweaked to your wishes * Tested in IE6 IE7 Firefox & Safari. Any browser strangeness, please report. */ (function ($) { $.fn.pager = function (options) { var opts = $.extend({}, $.fn.pager.defaults, options); return this.each(function () { // empty out the destination element and then render out the pager with the supplied options $(this).empty().append(renderpager(parseInt(options.pagenumber), parseInt(options.pagecount), options.buttonClickCallback)); // specify correct cursor activity // $('.pages li').mouseover(function () { document.body.style.cursor = "pointer"; }).mouseout(function () { document.body.style.cursor = "auto"; }); }); }; // render and return the pager with the supplied options function renderpager(pagenumber, pagecount, buttonClickCallback) { // setup $pager to hold render var $pager = $('<ul class="pages"></ul>'); // add in the previous and next buttons $pager.append(renderButton('First', pagenumber, pagecount, buttonClickCallback)).append(renderButton('Prev', pagenumber, pagecount, buttonClickCallback)); // pager currently only handles 10 viewable pages ( could be easily parameterized, maybe in next version ) so handle edge cases var startPoint = 1; var endPoint = 9; if (pagenumber > 4) { startPoint = pagenumber - 4; endPoint = pagenumber + 4; } if (endPoint > pagecount) { startPoint = pagecount - 8; endPoint = pagecount; } if (startPoint < 1) { startPoint = 1; } // loop thru visible pages and render buttons for (var page = startPoint; page <= endPoint; page++) { var currentButton = $('<li class="page-number">' + (page) + '</li>'); page == pagenumber ? currentButton.addClass('pgCurrent') : currentButton.click(function () { buttonClickCallback(this.firstChild.data); }); currentButton.appendTo($pager); } // render in the next and last buttons before returning the whole rendered control back. $pager.append(renderButton('Next', pagenumber, pagecount, buttonClickCallback)).append(renderButton('Last', pagenumber, pagecount, buttonClickCallback)); return $pager; } // renders and returns a 'specialized' button, ie 'next', 'previous' etc. rather than a page number button function renderButton(buttonLabel, pagenumber, pagecount, buttonClickCallback) { var $Button = $('<li class="pgNext">' + buttonLabel + '</li>'); var destPage = 1; // work out destination page for required button type switch (buttonLabel) { case "First": destPage = 1; break; case "Prev": destPage = pagenumber - 1; break; case "Next": destPage = pagenumber + 1; break; case "Last": destPage = pagecount; break; } // disable and 'grey' out buttons if not needed. if (buttonLabel == "First" || buttonLabel == "Prev") { pagenumber <= 1 ? $Button.addClass('pgEmpty') : $Button.click(function () { buttonClickCallback(destPage); }); } else { pagenumber >= pagecount ? $Button.addClass('pgEmpty') : $Button.click(function () { buttonClickCallback(destPage); }); } return $Button; } // pager defaults. hardly worth bothering with in this case but used as placeholder for expansion in the next version $.fn.pager.defaults = { pagenumber: 1, pagecount: 1 }; })(jQuery);
