如何在datatables服务器端添加编辑和删除按钮？

标签： mysql ajax flask datatables server-side

【解决方案1】：

我可以使用下面的脚本删除表记录，只有当我在 id_ates 中输入数字时，例如 id_ates=5，但如果我写 id_ates=id，它就不起作用...

(加载资源失败：服务器响应状态为404())

// Delete Record from Database.
    var table= $("#datatables").DataTable();
    $("#datatables").on('click',  '[id*=btnDelete]', function(){
    var id = $(this).attr("id_ates");
    if(confirm("Are you sure you want to delete?")) {
        $.ajax({
            "url": "{{url_for('delfiletest', id_ates=5)}}",
            method:"POST",
            data:{id_ates:id},
            success:function(data) {                    
                table.ajax.reload();
            }
        })
    } else {
        return false;
    }
});
