yii2分页之实现跳转到具体某页的实例代码

先上图看效果，大家感觉还错请参考功能怎么实现的！

从上图中不难看出，我们制定跳转到某页的功能是基于linkpager之上的扩展，这根我们之前实现的分页扩展明显不同，之前的明显就是重写了！当然，这都不重要，我们看看GoLinkPager的具体实现！名字起的有点lower,不重要！

1、在frontend\\components目录新建GoLinkPager类文件

2、该类继承yii\\widgets\\LinkPager;，如下：

namespace frontend\\components;

use yii\\widgets\\LinkPager;

use yii\\helpers\\Html;

class GoLinkPager extends LinkPager

{

}

3、添加属性public $go = false; //是否包含跳转功能跳转默认false

4、重写父类linkPager的renderPageButtons方法，具体直接参考下面完整版代码，可主要看go部分的代码实现。

<?php

namespace frontend\\components;

use yii\\widgets\\LinkPager;

use yii\\helpers\\Html;

class GoLinkPager extends LinkPager

{

// 是否包含跳转功能跳转默认false

public $go = false;

protected function renderPageButtons()

{

$pageCount = $this->pagination->getPageCount();

if ($pageCount < 2 && $this->hideOnSinglePage) {

return '';

}

$buttons = [];

$currentPage = $this->pagination->getPage();

// first page

$firstPageLabel = $this->firstPageLabel === true ? '1' : $this->firstPageLabel;

if ($firstPageLabel !== false) {

$buttons[] = $this->renderPageButton($firstPageLabel, 0, $this->firstPageCssClass, $currentPage <= 0, false);

}

// prev page

if ($this->prevPageLabel !== false) {

if (($page = $currentPage - 1) < 0) {

$page = 0;

}

$buttons[] = $this->renderPageButton($this->prevPageLabel, $page, $this->prevPageCssClass, $currentPage <= 0, false);

}

// internal pages

list($beginPage, $endPage) = $this->getPageRange();

for ($i = $beginPage; $i <= $endPage; ++$i) {

$buttons[] = $this->renderPageButton($i + 1, $i, null, false, $i == $currentPage);

}

// next page

if ($this->nextPageLabel !== false) {

if (($page = $currentPage + 1) >= $pageCount - 1) {

$page = $pageCount - 1;

}

$buttons[] = $this->renderPageButton($this->nextPageLabel, $page, $this->nextPageCssClass, $currentPage >= $pageCount - 1, false);

}

// last page

$lastPageLabel = $this->lastPageLabel === true ? $pageCount : $this->lastPageLabel;

if ($lastPageLabel !== false) {

$buttons[] = $this->renderPageButton($lastPageLabel, $pageCount - 1, $this->lastPageCssClass, $currentPage >= $pageCount - 1, false);

}

// go

if ($this->go) {

$goPage = $currentPage + 2;

$goHtml = <<<goHtml

<div class="form" style="float: left; color: #999; margin-left: 10px; font-size: 12px;">

<span class="text">共 {$pageCount} 页</span>

<span class="text">到第</span>

<input class="input" type="number" value="{$goPage}" min="1" max="{$pageCount}" aria-label="页码输入框" style="text-align: center; height: 25px; line-height: 20px; margin-top: 5px; width: 46px;">

<span class="text">页</span>

<span class="btn go-page" role="button" tabindex="0" style="border: solid 1px #ccc; padding: 0px; height: 25px; width: 46px; line-height: 25px;">确定</span>

</div>

goHtml;

$buttons[] = $goHtml;

$pageLink = $this->pagination->createUrl(false);

$goJs = <<<goJs

$(".go-page").on("click", function () {

var _this = $(this),

_pageInput = _this.siblings("input"),

goPage = _pageInput.val(),

pageLink = "{$pageLink}";

pageLink = pageLink.replace("page=1", "page="+goPage);

if (goPage >= 1 && goPage <= {$pageCount}) {
