php - Unexpected HTML result using List view JQuery -

-

my implementation @ : http://i.cs.hku.hk/~hsbashir/project_work/listview/list_view.html

the first entry when list hardcoded. second , third ones when extracted server using xmlhttp object. unable understand why in 2nd & 3rd list formatting different.

original html:

<!doctype html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css"> <script src="http://code.jquery.com/jquery-1.10.2.min.js"></script> <script src="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.js"></script> <script> lastrecord=0;     function loadnews(){             var xmlhttp;             if (window.xmlhttprequest) {               xmlhttp = new xmlhttprequest();             } else {               xmlhttp = new activexobject("microsoft.xmlhttp");             }             var x = document.getelementbyid("sample");             x.innerhtml = "hello";             xmlhttp.onreadystatechange = function () {               if (xmlhttp.readystate == 4 && xmlhttp.status == 200) {                   var news = document.getelementbyid("news_mesgs");                  news.innerhtml += xmlhttp.responsetext;                                  $("news_mesgs").enhancewithin();                }           }            xmlhttp.open("get", "querynews.php?lastrecord="+lastrecord,true);           xmlhttp.send();         } </script> </head> <body onload="loadnews()">  <div data-role="page" id="pageone">     <div data-role="main" class="ui-content">     <ul data-role="listview" data-inset="true" id="news_mesgs">         <li>         <a href="#">         <img src="http://i.cs.hku.hk/~hsbashir/project_work/listview/suicide-panel.jpg">         <h2> hku identifies new strategy protect flowers freezing stress </h2>         <p> sample description </p>         </a>         </li>      </ul>     </div> </div>    <div id="sample"></div> </body> </html>

updated html:

<!doctype html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.css"> <script src="http://code.jquery.com/jquery-1.10.2.min.js"></script> <script src="http://code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min.js"></script> <script>     lastrecord=0;     function loadnews(){         $('#sample').html( 'hello' );         $.get(          "querynews.php?lastrecord="+lastrecord,         function( data ) {             $('#news_mesgs').append( data )             .enhancewithin();         }     ); } </script> </head> <body onload="loadnews()">  <div data-role="page" id="pageone">     <div data-role="main" class="ui-content">     <ul data-role="listview" data-inset="true" id="news_mesgs">         <li>         <a href="#">         <img src="http://i.cs.hku.hk/~hsbashir/project_work/listview/suicide-panel.jpg">         <h2> hku identifies new strategy protect flowers freezing stress </h2>         <p> sample description </p>         </a>         </li>     </ul>     </div> </div>    <div id="sample"></div> </body> </html>

php

<? ...  mysql_connect($host,$username,$password); mysql_select_db($database) or die( "unable select database");       $query = "select * news_info";  $result = mysql_query($query) or die( "unable execute query");  while ($row = mysql_fetch_array($result)){         print "<li>";         print "<h2>".$row['title']."</h2>";         print "<p>sample description here</p>";         print "</a>";         print "</li>";     }  ?>

the second , third added after widget has been initialized. therefore have re-enhance (refresh) widget each time make update it. , can using $(parent_of_new_content).listview('refresh'). in case have call following:

$('#news_mesgs').listview( 'refresh' );

just out of curiosity, there particular reason why you're using plain vanilla js ajax call? if use jquery (recommended) function be:

lastrecord=0; function loadnews(){     $('#sample').html( 'hello' );     $.get(          "querynews.php?lastrecord="+lastrecord,         function( data ) {             $('#news_mesgs').append( data )             .listview( 'refresh' );         }     ); }

edit

please note in above code .enhancewithin() has been replaced .listview('refresh')
