jPaginate is a dynamic scrolling paging plug-in based on jQuery. It behaves like paging buttons. What is very interesting is that these buttons can scroll and can be controlled by clicking or sliding the mouse to the small arrows on both sides of the point. The button scrolls forward and backward.
PHPRead the first page of data:
<div id="pagetxt"> <?php $query = mysql_query("select id,title,addtime from article order by id desc limit 0, 6"); while ($row = mysql_fetch_array($query)) { $pubdate = date("Y-m-d", $row['addtime']); echo '<p><span>' . $pubdate . '</span><a href="http://www.jb51.net/js/' . $row['id'] . '.html" target="_blank">' . $row['title'] . '</a></p>'; } mysql_close(); ?> </div>
jQuery
$("#demo3").paginate({ count: <?php echo $page; ?>, //总记录数 start: 1, //开始显示的页数 display: 5, //分页条显示的页数 border: true, //是否显示页码的边框 border_color: '#BEF8B8', //设置边框的颜色 text_color: '#79B5E3', //设置页码的颜色 background_color: '#E3F2E1', //设置页码的背景色 border_hover_color: '#68BA64', //设置鼠标滑向页码时页码边框的颜色 text_hover_color: '#2573AF', //设置鼠标滑向页码时页码的颜色 background_hover_color: '#CAE6C6', //设置鼠标滑向页码时页码背景的颜色 images: false, //是否显示页码导航箭头 mouse: 'press', //设置为'press'时,当鼠标滑向导航箭头时,页码随之滚动;设置为'slide'时,鼠标单击一次导航箭头页码滚动一次。 onChange: function(page) { //当单击页码时,回调函数. $("#pagetxt").load("article.php?p=" + page); } }); article.php $p = isset($_GET['p']) ? intval($_GET['p']) : ""; $result = mysql_query("select id from article"); $total = mysql_num_rows($result); $pagesize = 6; //每页显示数 $page = ceil($total / $pagesize); //总页数 if ($p) { $startPage = ($p - 1) * $pagesize; $query = mysql_query("select id,title,addtime from article order by id desc limit $startPage, $pagesize"); while ($row = mysql_fetch_array($query)) { $pubdate = date("Y-m-d", $row['addtime']); echo '<p><span>' . $pubdate . '</span><a href="http://www.jb51.net/js/' . $row['id'] . '.html" target="_blank">' . $row['title'] . '</a></p>'; } }
The above is the entire content of this article, I hope you all like it.

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

在jquery中,apply()方法用于改变this指向,使用另一个对象替换当前对象,是应用某一对象的一个方法,语法为“apply(thisobj,[argarray])”;参数argarray表示的是以数组的形式进行传递。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

去掉方法:1、用“$(selector).removeAttr("readonly")”语句删除readonly属性;2、用“$(selector).attr("readonly",false)”将readonly属性的值设置为false。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。
