刷新/重新加载两个div时有一个延迟

Question

我使用codeigniter php框架工作我的项目我能够重新/重新加载我选择的div

<div class="content-wrapper">
    <div class="container-fluid">
        <ol class="breadcrumb">
            <li class="breadcrumb-item">
            <a href="#">Dashboard</a>
            </li>
            <li class="breadcrumb-item active">My Dashboard</li>
        </ol>
        <div class="row">
            <div class="col-sm-12 mb-3">
                <button class="btn btn-dark btn-lg" id="button-refresh"><i class="fa fa-refresh" aria-hidden="true"></i></button>
            </div>
        </div>
        <div class="row">
            <div class="col-sm-4">
                <div class="card text-white bg-primary o-hidden h-100" id="inbox-dashbord">
                    <div class="card-body" id="total_inbox">
                        <div class="card-body-icon">
                            <i class="fa fa-fw fa-comments"></i>
                        </div>
                        <div class="mr-5" id="newtotalinbox"><?php echo $total_inbox;?> New Messages</div>
                    </div>
                    <a class="card-footer text-white clearfix small z-1" href="<?php echo base_url('mail/inbox');?>">
                    <span class="float-left">View Inbox</span>
                    <span class="float-right">
                    <i class="fa fa-angle-right"></i>
                    </span>
                    </a>
                </div>
            </div>
        </div>
    </div>
</div>

两者之间似乎有几秒钟的延迟。 它不会同时改变。

  

询问如何确保同时完成两个div的刷新/重新加载？
