你好！

我對(duì)joomla中的組件的“自定義”分頁(yè)有問(wèn)題.

我想做一些用戶文章的列表,這些文章將顯示每頁(yè)3個(gè)帖子的示例.我的目標(biāo)是在不刷新網(wǎng)頁(yè)的情況下進(jìn)行分頁(yè). Ajax是最好的選擇.我現(xiàn)在正在與它斗爭(zhēng)并且到目前為止遇到了最困難的問(wèn)題(我試圖在幾個(gè)小時(shí)內(nèi)搜索我的問(wèn)題的答案).

user.php的

    <div class="userRightContainer">
            <div class="blogArticlesBlock">
            <div class="userItemTagsBlock"><b>Debaty na forum u?ytkownika(<?php echo $joomla_rows; ?>)</b></div>

            <?//artykuly joomla
            ?>

        <div id="Joomla_block" class="Joomla_block">
            <? require_once("Db_joomla.php") ?>

PS：
如果我在這個(gè)腳本中選擇“url：”Db_joomla.php“它將不會(huì)做任何事情.仍然不起作用(和相同的例外).

解決方法:

依靠Joomla的Ajax接口而不是實(shí)現(xiàn)你的接口總是一個(gè)更好的主意.它非常簡(jiǎn)單,非常高效,而且很有效.我們已經(jīng)寫(xiě)了如何使用它here.

基本上,您將創(chuàng)建/修改一個(gè)簡(jiǎn)單的模塊,該模塊將包含一個(gè)用于處理調(diào)用的函數(shù)(在其名稱末尾包含單詞Ajax).

然后,您將需要添加一個(gè)簡(jiǎn)單的jquery代碼,該代碼將通過(guò)com_ajax接口調(diào)用該模塊.請(qǐng)注意,您需要確保將模塊分配給菜單項(xiàng),因?yàn)槟枰摬藛雾?xiàng)的ID用于ajax調(diào)用.
