Javascript无法获取data-id

在我的codeigniter项目中，我创建了一个模型，当用户可以删除页面时，但在他或她这样做之前，它会弹出一个警告引导模态。

由于某些原因，我不能让我的data-id得到我的脚本。那么，当我点击yes来删除时它会将我发送到http://localhost/codeigniter/cms-1/admin/catalog/information/delete/但应该会拾取data-id并在删除后添加它例如http://localhost/codeigniter/cms-1/admin/catalog/information/delete/2

问题:为什么脚本不检测和抓取我的数据id，并将其添加到url时点击是模态?

我认为这部分工作不正确

removeBtn.attr('href', removeBtn.attr('href').replace(/(&|'?)'d*/, '$1' + id));

<script type="text/javascript">
$('#modal-from-dom').on('show', function() {
    var id = $(this).data('id'),
        removeBtn = $(this).find('.danger');
    removeBtn.attr('href', removeBtn.attr('href').replace(/(&|'?)'d*/, '$1' + id));
    $('#debug-url').html('Delete URL: <strong>' + removeBtn.attr('href') + '</strong>');
});
$('.confirm-delete').on('click', function(e) {
    e.preventDefault();
    var id = $(this).data('id');
    $('#modal-from-dom').data('id', id).modal('show');
}); 
</script>

查看data-id为data-id="<?php echo $information['information_id'];?>"的视图
