Question

我正在使用基于Yii的HumHub，并尝试使用从丰富文本的函数中提取的URL设置JS变量。

目前，该变量似乎没有在模型中设置，所以我甚至还没有真正开始使用该脚本。

它应该最终获取OpenGraph数据，但我甚至无法获得我打算调试和使用的脚本的URL。

Base enrichText功能

   /**
     * Converts an given Ascii Text into a HTML Block
     * @param boolean $allowHtml transform user names in links
     * @param boolean $allowEmbed Sets if comitted video links will embedded
     *
     * Tasks:
     *      nl2br
     *      oembed urls
     */
    public static function enrichText($text, $from = 'default', $postid = '')
    {

        if ( $from == 'default' ) {
            $maxOembedCount = 3; // Maximum OEmbeds
            $oembedCount = 0; // OEmbeds used

            // Parse bbcodes before link parsing
            $text = self::parseBBCodes($text);

            $text = preg_replace_callback('/(?<!\])(https?:\/\/.*?)(\s|$)(?!\[)/i', function ($match) use (&$oembedCount, &$maxOembedCount) {

                // Try use oembed
                if ($maxOembedCount > $oembedCount) {
                    $oembed = UrlOembed::GetOembed($match[0]);
                    if ($oembed) {
                        $oembedCount++;
                        return $oembed;
                    }
                }

                $regurl = "/(http|https)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";

                // Check if there is a url in the text independently and render to JS var
                if(preg_match($regurl, $text, $url)) {

                    if (!empty($postid)) {      
                        Yii::app()->clientScript->setJavascriptVariable("ourl".$postid, $url[0]);
                    }

                }

                return HHtml::link($match[1], $match[1], array('target' => '_blank')).$match[2];

            }, $text);

            // get user and space details from guids
            $text = self::translateMentioning($text, true);

            // create image tag for emojis
            $text = self::translateEmojis($text);

            return nl2br($text);

        } else {

            // Parse bbcodes before link parsing
            $text = self::parseBBCodes($text, $from);

            return $text;

        }
    }

更新我能够通过在文本末尾添加脚本来传递变量。非常非常脏的方法。我希望有更清洁的东西。：（

更新2：尝试获取Opengraph数据

这里我尝试从HHtml::enrichText()返回中的假设设置变量中获取opengraph中的数据。但是我收到错误：SyntaxError: expected expression, got '<' jquery.js:1指向jquery文件的第一行，这是脚本的注释和许可证。

该脚本也没有在源代码中显示
