Question

我创建了一个jQuery函数，当单击包含类button-trash的按钮时执行该函数。问题是当我点击按钮时没有反应，但alert中的$(document).ready(function()有效。

HTML

<div id="div_flotte">
<div class="div_avion" style="display:none;">
    <div class="panel panel-default">
          <div class="panel-heading">
          <div class="form-inline">
          <div class="input-group" style="width:200px">
              <span class="input-group-addon" id="basic-addon1">F-BEN</span>
              <input type="text" name="avions[][immat]" class="form-control" placeholder="Ex : 49" >
          </div>
          <div class="input-group" style="float:right;">
              <button class="btn btn-danger button-trash" type="button" name="button"><i class="fa fa-trash"></i></button>
          </div>

          </div>
         </div>
         <div class="form-group">
          <div class="input-group">
             <span class="input-group-addon" id="basic-addon1">Modèle</span>
             <input type="text" name="avions[][modele]" class="form-control" placeholder="Ex : 737" >
          </div>
         </div>
         <div class="form-group">
        <div class="input-group">

          </div>
         </div>
         <div class="form-group">
        <div class="input-group">
              <span class="input-group-addon" id="basic-addon1">Type de vol</span>
              <select name="avions[][type]" class="form-control-inline">
                <?php
                  foreach ($types_vol_avion as $cle => $value) {
                        echo '<option value="'.$cle.'">'.$value.'</option>';
                    }
                  ?>
            </select>
          </div>
         </div>
         <div class="form-group">
        <div class="input-group">
              <span class="input-group-addon" id="basic-addon1">Transport</span>
              <select name="avions[][activite]" class="form-control-inline">
                <?php
                  foreach ($Activite_avion as $cle => $value) {
                        echo '<option value="'.$cle.'">'.$value.'</option>';
                    }
                  ?>
            </select>
          </div>
         </div>
      </div>
    </div>
</div>

JS

$(document).ready(function(){
        $('.button-trash').click(function(){
            alert("test");
        });
        alert("test");
});

编辑： div .div_avion由此函数动态创建：

function AddAvion()
{
$( ".div_avion" ).eq(0).clone().attr({id:'div_avion'+($(".div_avion").length+1), style:'display:visible;'}).css('display', 'visible').appendTo( "#div_flotte" );
}

如果动态生成按钮，则应使用on（）方法

    <script>
        $(document).ready(function(){

                $('.input-group').on('click','.button-trash', function(){
                    alert ('it is working');
                    alert("test");
                });
                alert("test");
        });    

    </script>

$（'。class'）。click（）不起作用
