如何使用jQuery创建简单的分页

How to create easy pagination with jQuery jQuery pagination. All we know, that when we facing with necessarity to display large amount of data – we starting thinking about adding pagination. So we split all our content to several pages. And in this case – each page contain some part of our information. As usual this is server-side pagination, where we extracting necessary amount data from database for each page. But commonly, in case of small (or middle) data sets – we don`t need such pagination. And we can just use user-side pagination using javascript to manage with our pages. Today I will show you how to create such pagination.

如何使用jQuery创建简单的分页 jQuery分页。 我们所知道的是,当我们需要显示大量数据时,我们开始考虑添加分页。 因此,我们将所有内容分为几页。 在这种情况下,每个页面都包含我们的部分信息。 与往常一样,这是服务器端分页,在此我们从数据库中为每个页面提取必要的数据量。 但是通常,在数据集较小(或中等)的情况下,我们不需要这种分页。 而且,我们可以只使用使用JavaScript的用户端分页来管理我们的页面。 今天,我将向您展示如何创建这种分页。

A good thing, really, that the street outside looked quite miserable - the sun poking out for brief moments, only to make room for a patchy, nasty drizzle.

[/code]

As you see – we put all content inside <div id=\”content\”> element into P paragraphs. And than, using jQuery – doing small initialization of our pagination into prepared <div id=\”pagingControls\”></div> element. Inside our initialization js script – you can see that I set our container element, name of paragraph tag, and amount paragraphs per page (5). All easy.

如您所见–我们将<div id =“ content”>元素内的所有内容放入P段落中。 然后,使用jQuery –对已准备好的<div id =“ pagingControls”> </ div>元素进行分页小初始化。 在初始化js脚本中–您可以看到我设置了我们的容器元素,段落标签的名称以及每页的段落数(5)。 一切都容易。

Update! I changed tag for paragraphs <p> to <div class=\”z\”> for better selections. Now it able to handle with inline styles and tags

更新! 我将段落<p>的标记更改为<div class =“ z”>,以获得更好的选择。 现在它可以处理内联样式和标签

步骤2. CSS (Step 2. CSS)

Here are used CSS file. Just few styles for our demo:

这是用过CSS文件。 我们的演示仅提供几种样式:

css / styles.css (css/styles.css)

body{background:#eee;font-family:Verdana, Helvetica, Arial, sans-serif;margin:0;padding:0}.example{background:#FFF;width:1000px;font-size:80%;border:1px #000 solid;margin:0.5em 10% 0.5em;padding:1em 2em 2em;-moz-border-radius:3px;-webkit-border-radius:3px}#content p{text-indent:20px;text-align:justify;}#pagingControls ul{display:inline;padding-left:0.5em}#pagingControls li{display:inline;padding:0 0.5em}
body{background:#eee;font-family:Verdana, Helvetica, Arial, sans-serif;margin:0;padding:0}.example{background:#FFF;width:1000px;font-size:80%;border:1px #000 solid;margin:0.5em 10% 0.5em;padding:1em 2em 2em;-moz-border-radius:3px;-webkit-border-radius:3px}#content p{text-indent:20px;text-align:justify;}#pagingControls ul{display:inline;padding-left:0.5em}#pagingControls li{display:inline;padding:0 0.5em}

[/code]

步骤3. JS (Step 3. JS)

Here are two JS files:

这是两个JS文件:

js / jquery.min.js (js/jquery.min.js)

Both – just jQuery library. Available in package.

两者-只是jQuery库。 封装形式。

js / imtech_pager.js(由于一些更正而更新) (js/imtech_pager.js (updated due few corrections))

var Imtech = {};Imtech.Pager = function() {this.paragraphsPerPage = 3;this.currentPage = 1;this.pagingControlsContainer = \'#pagingControls\';this.pagingContainerPath = \'#content\';this.numPages = function() {var numPages = 0;if (this.paragraphs != null && this.paragraphsPerPage != null) {numPages = Math.ceil(this.paragraphs.length / this.paragraphsPerPage);}return numPages;};this.showPage = function(page) {this.currentPage = page;var html = \'\';this.paragraphs.slice((page-1) * this.paragraphsPerPage,((page-1)*this.paragraphsPerPage) + this.paragraphsPerPage).each(function() {html += \'<div>\' + $(this).html() + \'</div>\';});$(this.pagingContainerPath).html(html);renderControls(this.pagingControlsContainer, this.currentPage, this.numPages());}var renderControls = function(container, currentPage, numPages) {var pagingControls = \'Page: <ul>\';for (var i = 1; i <= numPages; i++) {if (i != currentPage) {pagingControls += \'<li><a href=\"#\" onclick=\"pager.showPage(\' + i + \'); return false;\">\' + i + \'</a></li>\';} else {pagingControls += \'<li>\' + i + \'</li>\';}}pagingControls += \'</ul>\';$(container).html(pagingControls);}}
var Imtech = {};Imtech.Pager = function() {this.paragraphsPerPage = 3;this.currentPage = 1;this.pagingControlsContainer = \'#pagingControls\';this.pagingContainerPath = \'#content\';this.numPages = function() {var numPages = 0;if (this.paragraphs != null && this.paragraphsPerPage != null) {numPages = Math.ceil(this.paragraphs.length / this.paragraphsPerPage);}return numPages;};this.showPage = function(page) {this.currentPage = page;var html = \'\';this.paragraphs.slice((page-1) * this.paragraphsPerPage,((page-1)*this.paragraphsPerPage) + this.paragraphsPerPage).each(function() {html += \'<div>\' + $(this).html() + \'</div>\';});$(this.pagingContainerPath).html(html);renderControls(this.pagingControlsContainer, this.currentPage, this.numPages());}var renderControls = function(container, currentPage, numPages) {var pagingControls = \'Page: <ul>\';for (var i = 1; i <= numPages; i++) {if (i != currentPage) {pagingControls += \'<li><a href=\"#\" onclick=\"pager.showPage(\' + i + \'); return false;\">\' + i + \'</a></li>\';} else {pagingControls += \'<li>\' + i + \'</li>\';}}pagingControls += \'</ul>\';$(container).html(pagingControls);}}

[/code]
