チャウダリーさん、これでうまくいくはずです。
バックエンドでリクエストを処理するために何かが必要になります。Java、PHP、Pythonなどを使用したかどうかを指定しなかったため、PHPを使用しました。これが私が最もよく知っていることです:D
擬似コード (loadmore.jsp)
Begin
widget = URL(widget) //the widget id or name
page = URL(page) //the page being retrieved
switch (widget)
{
case "widget1":
data_for_widget1 = paginated_query1(page)
print data_for_widget1
break
case "widget2":
data_for_widget2 = paginated_query2(page)
print data_for_widget2
break
default :
print "Invalid Widget"
break
}
End
PHPバージョン
<?php
if (isset($_GET['page'])) {
$widget = $_GET['page'];
$page = $_GET['page'];
switch ($widget) {
case "MyWidget1": //dynamic example
$manyManyItems; //A massive array of items
$pages = array_chunk($manyManyItems, 5); //break it up into chunks of 5 items
if( array_key_exists ($pages[$page]) )
for ($i = 0; $i < count($pages[$page]); $i++) { //load those chunks
echo '<div class="item">'.$pages[$page][$i].'</div>';
}
else {
echo "zero"; //code word that tells ajax that there is nothing more to load
}
break;
case "MyWidget2": //manual example
if($page==1) { //loads the first chunck manually
echo '<div class="item">dynamic content 1</div>';
echo '<div class="item">dynamic content 2</div>';
echo '<div class="item">dynamic content 3</div>';
}
elseif($page==2) { //loads the next batch
echo '<div class="item">dynamic content 1</div>';
echo '<div class="item">dynamic content 2</div>';
echo '<div class="item">dynamic content 3</div>';
}
else
echo "zero"; //code word that tells ajax that there is nothing more to load
break;
default:
echo "zero"; //code word that tells ajax that there is nothing more to load
}
}
?>
HTML
各ウィジェットは次のようになります
<div id="MyWidget1" class="widget" data-widgetPage="0">
<div class="item">default content</div>
<div class="item">another default content</div>
...
<div class="loadmoreajaxloader" style="display:none;"><center>Loading...</center></div>
</div>
Javascript
<script type="text/javascript">
$(".widget").scroll(function()
{
if($(this).scrollTop() == $(this).height() - $(this).height())
{
var nextPage = eval($(this).attr("data-widgetPage") + 1);
$(this).find('.loadmoreajaxloader').show();
$.ajax({
url: "loadmore.php?widget="+$(this).attr("id")+"&page="+nextPage,
success: function(html)
{
if(html != "zero")
{
$(this).append(html);
$(this).('.loadmoreajaxloader').hide();
}else
{
$(this).find('.loadmoreajaxloader').html('<center>No more posts to show.</center>');
}
}
});
$(this).attr("data-widgetPage", nextPage);
}
});
</script>
アプリでの成功。
