本文主要介绍了js对table和ul li实现前台分页,需要的朋友可以参考下
代码如下:
(function($) {
$.fn.tablepage = function(oObj, dCountOfPage, fresh_id) {
var dPageIndex = 1;
var dNowIndex = 1;
var sPageStr = "";
var dCount = 0;
var oSource = $(this);
var sNoSelColor = "#CCCCCC";
var sSelColor = "black";
var sFontColor = "white";
var nowIndex = 1;
change_page_content();
function change_page_content() {
// 取得資料筆數
dCount = oSource.children().children().length;
// 顯示頁碼
sPageStr = "<div class='ref'><a href='javascript：void(0)'id='fresh_"
+ fresh_id
+ "' onClick='fresh(this.id);' class='sx' style='color:#247AA9;'><span>刷新</span></a></div& gt;";
sPageStr += "<div class='msdn'><a href='javascript：void(0)'>首页</a><a href='javascript：void(0)'>上一页</a><a href='javascript：void(0)'>下一页</a><a href='javascript：void(0)'>尾页</a></div>";
sPageStr += "<div class='txt'>"+"共"+Math.ceil(dCount / dCountOfPage)+"页,当前第"+"<strong>"+dNowIndex+"</strong>"+" 页"+"</div>";
oObj.html(sPageStr);
dPageIndex = 1;
// 過濾表格內容
var rr=oSource.children().children("tr");
oSource.children().children("tr").each(function() {
// ==2
if (dPageIndex >= (((dNowIndex - 1) * dCountOfPage) + 1)
&& dPageIndex <= ((dNowIndex * dCountOfPage) )) {
$(this).show();
} else {
$(this).hide();
}
dPageIndex++;
});
// oSource.children().children("tr").first().show(); // head一定要顯示
if(dCount<=dCountOfPage){
var tt=$("#table_page_"+fresh_id).children('.msdn').children().each(function(i) {
if(i==2||i==3||i==0||i==1){
$(this).addClass("disabled");
}
});
}
else if(dNowIndex==Math.ceil(dCount / dCountOfPage)){
var tt=$("#table_page_"+fresh_id).children('.msdn').children().each(function(i) {
if(i==2||i==3){
$(this).addClass("disabled");
}
});
}else if(dNowIndex==1){
var tt=$("#table_page_"+fresh_id).children('.msdn').children().each(function(i) {
if(i==0||i==1){
$(this).addClass("disabled");
}
});
}
// 加入換頁事件
oObj.children().children().each(function() {
$(this).click(function() {
dNowIndex = $(this)[0].innerHTML;
if (dNowIndex == '首页') {
dNowIndex = 1;
change_page_content();
nowIndex = dNowIndex;
}
if (dNowIndex == '尾页') {
dNowIndex = Math.ceil(dCount / dCountOfPage);
change_page_content();
nowIndex = dNowIndex;
}
if (dNowIndex == '下一页') {
if (nowIndex < Math.ceil(dCount / dCountOfPage)) {
dNowIndex = parseInt(nowIndex) + 1;
change_page_content();
nowIndex = nowIndex + 1;
}
}
if (dNowIndex == '上一页') {
if (nowIndex > 1) {
dNowIndex = parseInt(nowIndex) - 1;
change_page_content();
nowIndex = nowIndex - 1;
}
}
});
});
}
};
})(jQuery);
代码如下:
<script type="text/javascript">
$(document).ready( function() {
var totalPage=$("ul li").length;
var total = Math.ceil($("ul li").length / 5);
var current = 1;
//var index =4;
if(totalPage>5){
$("ul li:gt(4)").hide();
$("#btnPrev").attr("class", "tabs-scroller-left-disabled").attr("disabled", "disabled").click( function() {
debugger;
$("#btnNext").attr("class", "tabs-scroller-right");
$("#btnNext").removeAttr("disabled");
current -= 1;
var tt=current;
$("ul li").show();
var indexStart = (current - 1);
var indexEnd = indexStart + 4;
$("li:lt(" + indexStart + "), li:gt(" + indexEnd + ")", $("ul")).hide();
if (current == 1){
$(this).attr("class", "tabs-scroller-left-disabled");
$(this).attr("disabled", "disabled");
}
});
$("#btnNext").click( function() {
debugger;
$("#btnPrev").attr("class", "tabs-scroller-left");
$("#btnPrev").removeAttr("disabled");
current += 1;
$("ul li").show();
var indexStart = (current - 1);
var indexEnd = current + 4> $("ul li").length - 1 ? $("ul li").length - 1 : current +3;
$("li:lt(" + indexStart + "), li:gt(" + indexEnd +")", $("ul")).hide();
if (current+4 >= totalPage){
$(this).attr("class", "tabs-scroller-right-disabled");
$(this).attr("disabled", "disabled");
}
});
}else{
alert(1);
$("#btnPrev").attr("class", "tabs-scroller-left-disabled");
$("#btnNext").attr("class", "tabs-scroller-right-disabled");
}
});
</script>
