如何獲得在另一個文件從PHP和JavaScript值

Question

file1.php

<select class="combo-boxs" name="doc_level" id="combo_doc"> 
    <option value="-">Choose Document Level</option> 
    <?php 

     $t=mysql_query("select * from dokumen_level limit 6",$con); 

     while($n=mysql_fetch_array($t)){ 
      if($dok_lvl==$n['nama_dok_level']){$selected='selected';}else{$selected='';} 
      $list_dok_level.='<option value="'.$n['nama_dok_level'].'" '.$selected.'>'.$n['nama_dok_level'].'</option>'; 
      } 

      echo $list_dok_level; 
      ?> 
      </select> 


<input type="text" name="no_document" id="no_document" size="30" disabled="disabled" /> 


    <script> 
    $("select").change(function() { 
     var str =$("#combo_issuer").val(); 
     var doc =$("#combo_doc").val(); 

if(str!="" && doc!=""){ 
    $.get("get_name.php", {issuer: str, doc_lvl: doc}, function(data){ 
    //get the value from the get_name.php file and asign to display_name text filed 
    $("#no_document").val(data.split("-")[0]); 
    }); 
} 
}) 
    .change(); 

</script> 

file2.php

$ID = $_GET['issuer']; 
$doc_lvl = $_GET['doc_lvl'];  

$sql1= mysql_query("SELECT MAX(id_dokumen) AS maxid from dokumen_internal WHERE issuer='".$ID."'"); 
$m=mysql_fetch_array($sql1); 
$id_dok_max=$m['maxid']; 

$sql3 = mysql_query("SELECT substring(no_dokumen, 11, 3) AS nomor FROM dokumen_internal WHERE id_dokumen='$id_dok_max' ") or die(mysql_error()); 
            $n=mysql_fetch_array($sql3); 
            $nomor_max=$n['nomor']; 
            $no=$nomor_max++; 
            $no_inc=sprintf("%03s",$nomor_max); 

$sql= mysql_query("SELECT * FROM departemen WHERE id_departemen = '".$ID."'"); 
$row = mysql_fetch_array($sql); 
$display="SS/".$doc_lvl."/".$row['id_departemen'].$no_inc; 
echo "SS/".$doc_lvl."/".$row['id_departemen'].$no_inc; 

此代碼是成功地顯示我想要的..但​​我不能讓從現場文本從no_document

<input type="text" name="no_document" id="no_document" size="30" disabled="disabled" /> 

我想獲得鑲片。你可能知道哪裏是錯誤？ ..非常感謝你..

如果你設置輸入標籤的禁用屬性，那麼它不會被髮布，你必須設置字段只讀屬性。 例如：

<input type="text" name="no_document" id="no_document" size="30" readonly="readonly" />
