Question

我有一张表格，显示存储在mysql数据库中的电影评论。可以使用驻留在引导模式中的表单来编辑这些评论中的每一个。我遇到的问题是我无法理解如何在模态中为每个表单提供一个唯一的ID。目前，模态只能从数据库中的第一行评论中回应varibales。非常感谢。

Jquery

 <script type="text/javascript">
//Edit Review 
$(document).ready(function(){
$(".editReview").click(function (e) {
$('#myModal').modal({
            e.preventDefault();

        var username = $(this).data("username");
        var film_id = $(this).data('filmid');
        var id = $(this).data('id');
        var review = $(this).data('review');


$.post('ajax_editReview.php', {username: username, film_id: film_id, id: id, review: review},
function(data){
$('#myModal').modal('hide');
$("#message").html(data);
  $("#review").val('');
$("#message").fadeIn(500);
$("#message").fadeOut(2500); 
});
return false;
});
});
</script>

表格

 <div class="container">

  $sql = "SELECT * FROM user_reviews WHERE username='$username' ORDER BY DATE desc";
$result = $db_conx->query($sql);

$id = $row['id']; 
$film_id = $row['film_id']; 
$review = $row['review']; 
$movie = $tmdb->getMovie ($film_id);

你需要在你的页面上只有一次模态，看起来你是为每次评论创建一个新模式，你不需要这样做，只需输出一次。

然后您需要像这样使用事件show.bs.modal。

$('#myModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var username = button.data("username");
  var film_id = button.data('filmid');
  var id = button.data('id');
  var review = button.data('review');

  ....
});

将变量传递给bootstrap模式窗体
