スクロールがdiv要素

Question

<script type="text/javascript"> 
 

 
    $(document).ready(function(){ 
 
     refreshTable(); 
 
    }); 
 

 
    function refreshTable(){ 
 
     $('#mainDiv').load('home.php', function(){ 
 
      setTimeout(refreshTable, 5000); 
 
     }); 
 
    } 
 
</script>

こんにちはでトップに、私はmainDiv内2.phpから5秒ごとに内容をロード1.phpでこのコード/スクリプトを持っています。今度は、新しいデータがdivの中の2.phpから読み込まれるたびに、mainDivを上にスクロールします。私にコード/スクリプトを表示してこれを達成する方法を教えてください。ありがとう。

Answer 1

divをスクロールするには、次のコードを使用します。

$('html, body').animate({ 
    scrollTop: $('#mainDiv').offset().top 
}, 'slow'); 

理解を深めるために以下のスニペットを確認してください。 div内にダミーデータを入力したので、スクロールしたdivのアイデアを得ることができます。

$(document).ready(function(){ 
 
    refreshTable(); 
 
}); 
 

 
function refreshTable(){ 
 
    $('#mainDiv').load('test.php', function(){   
 
     $('html, body').animate({ 
 
      scrollTop: $('#mainDiv').offset().top 
 
     }, 'slow'); 
 
     setTimeout(refreshTable, 5000); 
 
    }); 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div id="mainDiv"> 
 
    
 
Why do we use it? 
 

 
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
