如何在javascript中的循環中從數據庫中獲取數據

-1

<script> <?php if($pid>0) { ?> 
    var counter=<?php echo $rnum ?>; <?php } else { ?> 
var counter = 1; <?php } ?> 
var limit = 25; 
//function addInput()--------  
    function addInput() 
     { 
     var dt=counter+1; dpid="#datepicker1".concat(dt); dp="datepicker1".concat(dt); djid="#datepicker2".concat(dt); dj="datepicker2".concat(dt); 

     if (counter == limit) { 
      alert("You have reached the limit of adding " + counter + " inputs"); 
     } 
     else { 
      var newdiv = document.createElement('div'); 
      newdiv.innerHTML = "<div class='row no-margin' id='row"+dt+"'><div class='col-md-6 input box'><input name='tkid[]' type='hidden' value='0' id='itemid"+dt+"'><select name='item[]' ><option value='' disabled selected required>Deliverables</option><option value='website'>Website</option><option value='app'>Web Application</option><option value='domain'>Domain Registration</option><option value='hosting'>Hosting</option><option value='content'>Content Writing</option><option value='logo'>Logo Creation</option><option value='analytics'>Google Analytics</option></select></div><div class='col-md-6 input box'><select name='assignedto[]'><option value='' disabled selected required>Assigned To</option><option value='value1'> Value1</option><option value='value2'>Value2</option></select></div><div class='col-md-6 input box' id='dynamicInput1'><input type='text' id='".concat(dp).concat("' name='actualtime[]' placeholder='Actual Time Required' value='' required></div><div class='col-md-5 input box' id='dynamicInput1'><input type='text' id='").concat(dj).concat("' name='ddate[]' placeholder='Delivery Date' value='' required></div><div class='col-md-1 input box'><i class='fa fa-times' aria-hidden='true' onclick='deleteinput("+dt+")'></i></div></div>"); 
      dp=document.getElementById('dynamicInput').appendChild(newdiv); 
      dg=document.getElementById("dynamicInput").style.display="inline-block"; 
      counter++; 
      document.getElementById("count").value=counter; 
      $(dpid).datepicker({minDate: new Date(),dateFormat:'yy-mm-dd'}); 
      $(djid).datepicker({minDate: new Date(),dateFormat:'yy-mm-dd'}); 

     } 
     //data: {'aid':aid}, 
     $.ajax({ 
      url: 'project.php', 
      type: 'post', 
      data: 'dcount'+counter, 
      success: function(output) 
      { //$(".container").html(output) 
       //alert(dt); 
       //alert('success, server says '+output); 
      }, error: function() 
      { 
       alert('something went wrong, rating failed'); 
      } 

     }); 
     }; 

</script>

如何從數據庫中將值輸入到選擇選項中。不是從上面的代碼。這是一個動態添加文本字段。我希望在動態字段中將值添加到數據庫中。如何在javascript中的循環中從數據庫中獲取數據

你的問題不是很清楚，我

如果你所要求的技術添加與動態輸入選擇菜單，更好地利用AJAX

像

AJAX：

$.ajax({ 
type: 'post', 
url: 'list.php', 
data: { 
list1 :val 
}, 
success: function (response) { 
document.getElementById("itemlist").innerHTML=response; 
} 
});

PHP

<?php 
if(isset($_POST['list1'])) 
{ 
$state = $_POST['list1']; 
$find=mysqli_query($con,"select city from places where state='$state'"); 
while($row=mysqli_fetch_array($find)) 
{ 
echo "<option>".$row['item']."</option>"; 
} 
exit; 
} 
?>
