這篇文章主要介紹了jquery實現pager控件示例,需要的朋友可以參考下
js： 代碼如下: $.fn.extend({ JPager: function (cfg, pageIndex, pageSize) { if (cfg && pageIndex > 0 && pageSize>0) { var token = "#" + this.attr("id"); this.empty(); var pageFirst = function () { $(token).JPager(cfg, 1, pageSize); }; var pagePre = function () { $(token).JPager(cfg, pageIndex - 1, pageSize); }; var pageLast = function () { $(token).JPager(cfg, parseInt($("#_tot").val()), pageSize); }; var pageNext = function () { $(token).JPager(cfg, pageIndex + 1, pageSize); }; var pageNumber = function () { $(token).JPager(cfg, parseInt($(this).text()), pageSize); }; var pageGo = function () { var index = parseInt($("#_pos").val()); var total = parseInt($("#_tot").val()); if (index) { if (index > total) { $(token).JPager(cfg, total, pageSize); } else if (index < 1) { $(token).JPager(cfg, 1, pageSize); } else { $(token).JPager(cfg, index, pageSize); } } }; var checkGoNumber = function () { if (!Number(this.value)) { this.value = ""; } else { this.value = Number(this.value); } }; var initCustomer = function (recordCount) { if (cfg.customer) { if (cfg.customer.template) { var t = cfg.customer.template; t = t.replace(/%total%/gi, Math.ceil(recordCount / pageSize)).replace(/%current%/gi, pageIndex).replace(/%recordCount%/gi, recordCount).replace(/%pageSize%/gi, pageSize); if (cfg.customer.position == "right") { $("#_right").after(t); } else { $("#_left").before(t); } } } }; var changeState = function (total) { if (pageIndex == 1) { $("#_first").attr("class", "unable"); $("#_pre").attr("class", "unable"); } else { $("#_first").bind("click", pageFirst).attr("class", "number"); $("#_pre").bind("click", pagePre).attr("class", "number"); } if (pageIndex == total) { $("#_last").attr("class", "unable"); $("#_next").attr("class", "unable"); } else { $("#_last").bind("click", pageLast).attr("class", "number"); $("#_next").bind("click", pageNext).attr("class", "number"); } }; var initNumber = function (total, count, current) { if (total > 0 && count > 0) { if (current < 1) { current = 1; } if (current > total) { current = total; } var endIndex = total; var startIndex = 1; var temp = current + Math.floor(count / 2); if (temp < total) { if (temp < count) { endIndex = count; } else { startIndex = temp - count + 1; endIndex = temp; } } else { if (total > count) { startIndex = total - count + 1; } } $("#_number").empty(); for (var i = startIndex; i <= endIndex; i++) { var html = $("<span></span>").text(i).bind("click", pageNumber); if (i == current) { $("#_number").append(html.attr("class", "selected")); } else { $("#_number").append(html.attr("class", "number")); } } } }; var initPager = function (data) { if ($.isArray(data.SearchResult) && data.RecordCount > 0) { $(token).append("<span id='_left'><span id='_first' class='spcial'>首頁</span> <span id='_pre' class='spcial'>上一頁</span></span> <span id='_number'></span><span id='_go'><input id='_pos' type='text'/><input id='_to' type='button' value='GO'/></span> <span id='_right'><span id='_next' class='spcial'>下一頁</span> <span id='_last' class='spcial'>末頁</span></span><input id='_tot' type='hidden'/>"); var total = Math.ceil(data.RecordCount / pageSize); $("#_tot").val(total); $("#_pos").bind("blur", checkGoNumber); $("#_to").bind("click", pageGo); changeState(total); if (cfg.showNumber && cfg.count > 0) { initNumber(total, cfg.count, pageIndex); } initCustomer(data.RecordCount); } }; if (cfg.action) { if (cfg.action.url && cfg.action.data) { var d = cfg.action.data.substr(0, cfg.action.data.lastIndexOf("}")) + ',"pageIndex":' + pageIndex + ',"pageSize":' + pageSize + "}"; if (cfg.action.callback && $.isFunction(cfg.action.callback)) { $.ajax({ type: "post", url: cfg.action.url, dataType: "json", contentType: "text/json", data: d, success: function (data) { initPager(data.d); cfg.action.callback(data.d); } }); } else { $.ajax({ type: "post", url: cfg.action.url, dataType: "json", contentType: "text/json", data: d, success: function (data) { initPager(data.d); } }); } } } } } }); css： 代碼如下: #_pos { width: 40px; } .unable { color: #BCC0BB; } .number { margin: 2px; color:#0000FF; text-decoration:underline; } .selected { margin: 2px; color: #FF0000; font-weight: bold; } html： 代碼如下: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>分頁控件示例</title> <link href="CSS/JPager.css" rel="stylesheet" type="text/css" /> <script src="JS/jquery.min.js" type="text/javascript"></script> <script src="JExtension/JPager.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#pager").JPager({ customer:{template:"%cuRRent%"},count: 10, action: { url: "Service/JService.svc/GetPersons", data: '{"name":"zhoulq"}'}, showNumber: true },1,5); }); </script> </head> <body> <table> </table> <div id="pager"></div> </body> </html> wcf： 代碼如下: using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel;
