javascript - ajax 加载 gif 成功后未删除

Question

我目前有一个表，通过 ajax 请求加载一堆结果，您可以看到下面的代码。但是，当我尝试添加加载 gif 时，我只在页面上看到加载 gif，在 ajax 请求成功后，它不会自行删除

我可以看到页面触发ajax请求并返回数据

我正在追逐加载栏以在ajax处理时显示，然后在加载时隐藏

这是html代码

<div class='content'>
    <div class='panel panel-flat' id='records_loading'>
        <table class='table table-togglable table-hover table-striped' data-limit-navigation='5' data-page-size='20'>
            <thead class='bg-teal'>
                <tr>
                    <th data-toggle='true' data-type='numeric'>SMS ID</th>
                    <th data-hide='phone'>Time Stamp</th>
                    <th data-hide='phone,tablet'>Mobile Number</th>
                    <th data-hide='phone,tablet'>Message</th>
                    <th data-hide='phone,tablet'>Message Status</th>
                </tr>
            </thead>
            <tbody  id='records_table'>
            </tbody>
        </table>
    </div>
<ul class='pagination pagination-separated hide-if-no-paging'></ul>
</div>

这是ajax代码

<script>
function showResult(str) {  
    $.ajax({
        url: '/getjson.php?search='+str, 
        type: 'POST',    
        dataType:'json',
        beforeSend:function(response)
       {
        $('#records_loading').html('<img src="assets/content/login.gif">');
       },
        success: function (response) 
        {
          var trHTML = '';
          $.each(response, function (key,value) {
             trHTML += 
                '<tr><td>' + value.ID + 
                '</td><td>' + value.Timestamp + 
                '</td><td>' + value.Number + 
                '</td><td>' + value.Message + 
                '</td><td>' + value.Status + 
                '</td></tr>';     
          });
            $('#records_table').html(trHTML);
            $('.table-togglable').trigger('footable_redraw');
        }
    }); 
}
showResult('');
</script>

    success: function (response) 
    {
       $('#records_loading').html('<table class='table table-togglable table-hover table-striped' data-limit-navigation='5' data-page-size='20'><thead class='bg-teal'>');
    }
