ここにコードがあります。IE7のjquery.ui.autocomplete.jsでの問題

input.trigger("activate.autocomplete", [$.data(active[0], "originalObject")]); $("body").trigger("off.autocomplete"); 

作品完全にFirefoxで/クローム/オペラ:IE7は「『active.0』 nullまたはオブジェクトではありません」であるライン39上の誤差を、噴出します。何か案は?多くのありがとうと非常に感謝します。ここで

最初JavaScriptを働く私のコードです:

$(".student_search").autocomplete("student_search.php", { 
       minChars: 2, 
       cacheLength: 20, 
       matchContains: true, 
       highlightItem: true, 
       parse: function(data) { 
          return $.map(eval(data), function(row) { 
           return { 
             data: row, 
             value: row.studentname, //value being searched for 
             result: row.studentidnumber //value in text input 
             } 
          }); 
       }, 
       formatItem: function(row, i, max, term) { 
        return "<span style='font-size: 110%;'>" + row.studentname + "</span><br/>" + "ID: " + row.studentidnumber + ", " + " Grade: " + row.studentgradenumber; 
          }, 
       formatResult: function(row, i, max){ 
        return row.studentidnumber; 
       } 
     }); 

});

ここにPHPファイルのコードを示します。 JSONオブジェクトをデータと共に出力します。

if(isset($_GET['q'])){ 
require_once("php/mysql.connect.php"); 
$request = strtolower($_GET['q']); 
$query = mysql_query("SELECT 
        CONCAT(studentfname, ' ', studentlname, '') 
         AS studentname, studentidnumber, 
          CONCAT(studentgradenumber, 'th') 
           AS studentgradenumber 
            FROM studentinfo 
             WHERE studentlname LIKE '%".$request."%' 
              OR studentfname LIKE '%".$request."%' 
               OR studentidnumber LIKE '%".$request."%'") or die(mysql_error()); 

$results = array(); 

$i = 0; 
while($row = mysql_fetch_assoc($query)) //fetch each result using the column name as the array key 
{ 
    foreach($row as $column=>$val) //loop through each column 
    { 
    $results[$i][$column] = $val; //build array using incremental row # and column name 
    } 
    $i++; //increase the row counter 
}  
print json_encode($results); 
} 

印刷されるJSONオブジェクトがある:

[{"studentname":"Joe Schmo","studentidnumber":"123456","studentgradenumber":"11th"}] 

ようrow.studentname戻りジョーばか者。ここで、rowは関数内の変数の名前で、studentnameはJSONオブジェクトからのキーの名前です。

乾杯!

jquery uiバージョン1.8.9とIE7のオートコンプリートに問題がありました。私は1.8.16を使用しています。
