自动更新没有重复内容

Question

我创建了一个基本输出匹配结果列表的短代码。这些匹配结果由JSON脚本解析，该脚本连接到服务器上的cron作业，每5分钟更新一次。而不是人们刷新浏览器本身我想知道我怎么能够使用AJAX，Jquery自动更新这个并且不重复匹配？

短代码如下：

[resultpage]

短代码功能：

function resultpage() {



    $output = '';



    $output .= '<div id="content">';
        $output .= '<div id="part-1">';

        $output .= getgames("lol");


        $output .= '</div>';
       $output .= ' <div id="part-2">';
       $output .= getgames("counterstrike");
       $output .= ' </div>';
       $output .= ' <div id="part-3">';
       $output .= getgames("dota2");
       $output .= ' </div>';
       $output .= ' <div id="part-4">';
       $output .= getgames("hearthstone");
       $output .= ' </div>';
    $output .= '</div>';




return $output;
}

getGames函数

function getgames($thegame) {
$json = file_get_contents('JSON URL');
$obj = json_decode($json);
$livegames = $obj->live;  


$output = '';

foreach($livegames as $live){



        if ($live->game == $thegame) {
            $teamarray = returnteam($live->{'team 1'}->name, $live->{'team 2'}->name);

        if ($live->{'team 1'}->score == "") {
            $score1 = '0';
        }else {
            $score1 = $live->{'team 1'}->score;
        }
        if ($live->{'team 2'}->score == "") {
            $score2 = '0';
        } else {
            $score2 = $live->{'team 2'}->score;
        }



        $output .= '<div class="result-in-month">';

        $output .= '<div class="result-date">';
        $output .= $live->{'live in'};
        $output .= '</div>';
                $output .= '<div class="result-match-team-wrapper">';
                    $output .= '<span class="result-match-team left">';
                        $output .= $teamarray[0];

                    $output .= '</span>';
                    $output .= '<span class="result-match-versus">';
                        $output .= '<span class="result-match-score">'. $score1 .'</span><span class="result-match-separator">-</span><span class="result-match-score">'. $score2 .'</span>';
                    $output .= '</span>';
                    $output .= '<span class="result-match-team right">';
                    $output .= $teamarray[1];

                    $output .= '</span>';
                $output .= '</div>';
                $output .= '<div class="result-stream">';
                $output .= '<a href="'. $live->{'streams'}[0] .'">';
                $output .= 'Stream';
                $output .= '</a>';
                $output .= '</div>';

            $output .= '<div class="clear"></div>';

        $output .= '</div>';

    }
    }
}
