私はこのコードを持っています:
//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()))
});
.current {
color: green;
}
#pagin li {
display: inline-block;
}
<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">
<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>
HTMLファイルに手動で数値を書き込む代わりに、表示するdivの数に応じて数値を自動的に生成する必要があります。
私が持っているコードは機能しますが、3ページと4ページには何もありません。HTMLファイルの数値を更新する代わりに、Jqueryで動的に変更したいです。
ループを介してページ数を計算し、ページへのリンクを作成します。
//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()))
});
.current {
color: green;
}
#pagin li {
display: inline-block;
}
<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>
Math.ceil($(".line-content").size() / pageSize)
を使用してページをカウントしてから、ページごとに<li>
を動的に追加する必要があります。
初期化コードを$()内に移動しました(つまり、Readyイベント)。
//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();
});
}
.current {
color: green;
}
#pagin li {
display: inline-block;
}
<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>
これは、DOMの準備ができたときに実行される場所ですが、クリックイベントハンドラーが追加される前に配置します。
//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);
次に、#pagin
を空のままにしておくと、JavaScriptがそれを埋めます。
<ul id="pagin">
</ul>

これはあなたが必要としていたものにインラインです。
htmlのタグに追加したい場合は、これらのコードをページ付けに使用できます。
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() {
