我有这段代码:
//Pagination
pageSize = 8;
showPage = function(page) {
$(".line-content").hide();
$(".line-content").each(function(n) {
if (n >= pageSize * (page - 1) && n < pageSize * page)
$(this).show();
});
}
showPage(1);
$("#pagin li a").click(function() {
$("#pagin li a").removeClass("current");
$(this).addClass("current");
showPage(parseInt($(this).text()))
});
&#13;
.current {
color: green;
}
#pagin li {
display: inline-block;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="line-content">1 I have some content</div>

<div class="line-content">11 I have some content</div>
<div class="line-content">12 I have some content</div>
<ul id="pagin">
<li><a class="current" href="#">1</a></li>
<li><a href="#">2</a></li>
<li><a href="#">3</a></li>
<li><a href="#">4</a></li>
</ul>

我不想在我的HTML文件中手动编写数字,而是希望根据要显示的div数自动生成数字。
我的代码有效,但第3页和第4页没有任何内容。我希望它们能够使用Jquery动态更改
,而不是更新HTML文件中的数字。答案 0 :(得分:5)
计算页数而不是通过循环创建指向页面的链接。
//Pagination
pageSize = 8;
var pageCount = $(".line-content").length / pageSize;
for(var i = 0 ; i<pageCount;i++){
$("#pagin").append('<li><a href="#">'+(i+1)+'</a></li> ');
}
$("#pagin li").first().find("a").addClass("current")
showPage = function(page) {
$(".line-content").hide();
$(".line-content").each(function(n) {
if (n >= pageSize * (page - 1) && n < pageSize * page)
$(this).show();
});
}
showPage(1);
$("#pagin li a").click(function() {
$("#pagin li a").removeClass("current");
$(this).addClass("current");
showPage(parseInt($(this).text()))
});

您需要使用Math.ceil($(".line-content").size() / pageSize)
统计网页,然后为每个页面动态添加<li>
。
我已将初始化代码移到$()内(即Ready事件)。
//Pagination
pageSize = 8;
$(function() {
var pageCount = Math.ceil($(".line-content").size() / pageSize);
for (var i = 0; i < pageCount; i++) {
if (i == 0)
$("#pagin").append('<li><a class="current" href="#">' + (i + 1) + '</a></li>');
else
$("#pagin").append('<li><a href="#">' + (i + 1) + '</a></li>');
}
showPage(1);
$("#pagin li a").click(function() {
$("#pagin li a").removeClass("current");
$(this).addClass("current");
showPage(parseInt($(this).text()))
});
})
showPage = function(page) {
$(".line-content").hide();
$(".line-content").each(function(n) {
if (n >= pageSize * (page - 1) && n < pageSize * page)
$(this).show();
});
}
&#13;
.current {
color: green;
}
#pagin li {
display: inline-block;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="line-content">1 I have some content</div>
<div class="line-content">2 I have some content</div>
<div class="line-content">3 I have some content</div>
<div class="line-content">4 I have some content</div>
<div class="line-content">5 I have some content</div>
<div class="line-content">6 I have some content</div>
<div class="line-content">7 I have some content</div>
<div class="line-content">8 I have some content</div>
<div class="line-content">9 I have some content</div>
<div class="line-content">10 I have some content</div>
<div class="line-content">11 I have some content</div>
<div class="line-content">12 I have some content</div>
<ul id="pagin">
</ul>

答案 2 :(得分:2)
将它放在DOM准备就绪时执行的地方,但是在添加click事件处理程序之前。
//How many pages do we want?
elementCount = $('.line-content').size();
pageCount = Math.ceil(elementCount / pageSize);
//Add the buttons.
buttons = '';
for(i=1; i<=pageCount; i++) {
buttons += '<li><a href="#">' + i + '</a></li>');
}
$('#pagin').html(buttons);
然后您可以将#pagin
留空,JavaScript会为您填写:
<ul id="pagin">
</ul>
Disclaimar:我还没有测试过这段代码。

//Pagination
pageSize = 8;
showPage = function(page) {
$('.line-content').hide();
$('.line-content:gt('+((page-1)*pageSize)+'):lt('+(page)*(pageSize-1)+')').show();
$('.line-content:eq('+((page-1)*pageSize)+')').show();
}
var pgs = Math.ceil($('.line-content').length/pageSize);
var pgnt = '';
for(var i=1;i<=pgs;i++){
pgnt += '<li><a href="#">'+i+'</a></li>';
}
$('#pagin').html(pgnt);
$("#pagin li a").click(function() {
$("#pagin li a").removeClass("current");
$(this).addClass("current");
showPage(parseInt($(this).text()))

如果您希望在html中附加标记,则可以使用这些代码进行分页。
var paginationfooter = {};
paginationfooter.Pager = function() {
this.currentPage = 1;
this.pagingnumber = "#pagingnum";
this.tagg = "#matn";
this.numPages = function() {
var numPages = 0;
if (this.paragraphs != null && this.limit != null) {
numPages = Math.ceil(this.paragraphs.length / this.limit);
}
return numPages;
};
this.showPage = function(page) {
this.currentPage = page;
var html = "";
for (var i = (page-1)*this.limit; i < ((page-1)*this.limit) + this.limit; i++) {
if (i < this.paragraphs.length) {
var disply = this.paragraphs.get(i);
html += "<" + disply.tagName + ">" + disply.innerHTML + "</" + disply.tagName + ">";
}
}
$(this.tagg).html(html);
pagenuming(this.pagingnumber, this.currentPage, this.numPages());
}
var pagenuming = function(container, currentPage, numPages) {
var paging = $("<div class='pagination'></div>");
var gridpaging = "<ul>";
for (var i = 1; i <= numPages; i++) {
if (i != currentPage) {
gridpaging += "<li><a href='#' onclick='pager.showPage(" + i + "); return false;'>" + i + "</a></li>";
} else {
gridpaging += "<li>" + i + "</li>";
}
}
gridpaging += "</ul>";
paging.append(gridpaging);
$(container).html(paging);
}
}
//---------------------------here input values
var pager = new paginationfooter.Pager();
$(document).ready(function() {
pager.limit = 5;
pager.pagingtag = $('#matn');
pager.paragraphs = $('p', pager.pagingtag);
pager.showPage(1);
});
