需求多加一個類似phpmyadmin一樣的每頁顯示條數查了好久都沒找到
看到thinkphp 分頁類別是html拼接的很low 但是方便了我修改新增需求
在原生分頁類別基礎上新定義了一個num變數
#show方法返回的時候thinkphp拼接html的地方新加了一段選擇條數的程式碼
return "<ul class='am-pagination am-pagination-right'>{$page_str}</ul>
<div class='am-dropdown am-dropdown-up' data-am-dropdown>
<button class='am-btn am-btn-primary am-dropdown-toggle' data-am-dropdown-toggle>显示条数 <span class='am-icon-caret-up'></span></button>
<ul class='am-dropdown-content'>
<li><a href='".$this->urlNum(10,1)."'>10</a></li>
<li><a href='".$this->urlNum(30,1)."'>30</a></li>
<li><a href='".$this->urlNum(50,1)."'>50</a></li>
</ul>
</div>";然後新加的urlNum方法是這樣：
private function urlNum($num,$page){
$str = str_replace(urlencode('[PAGE]'), $page, $this->url);
return str_replace(urlencode('[NUM]'), $num, $str);
}開始的時候由於page這個變數thinkphp會先變一個轉碼的後面才替換
而且page=1的時候url裡是不顯示的但是還有這個參數
導致num這個變數老是搞得url 很不穩定經常疊加
#後面只有做了一個小犧牲(選定每頁顯示條數的時候url page即使為1 也會加上)
不過這並沒有什麼影響
整個程式碼分頁類別就是這樣：
