Question

让我说我有

<div id="printOnly">
     <b>Title</b>
     <p>
        Printing content 
     </p>
</div>

是否可以在页面渲染时隐藏此div并仅在打印此div时显示？

Answer 1

你需要一些css

#printOnly {
   display : none;
}

@media print {
    #printOnly {
       display : block;
    }
}

Answer 2

@media screen
{
    #printOnly{display:none;}
}

@media print
{
    #printOnly{}
}

Answer 3

您应该使用媒体查询。

在你的情况下：

#printOnly {
    display: none;
}

@media print { 
    #printOnly {
        display: block;
    }
}

Answer 4

您可以使用media="print"属性附加外部css样式表：

<link rel="stylesheet" type="text/css" media="print" href="print.css">

Answer 5

我认为最好的解决方案是围绕不可打印的东西创建一个包装器：

<head>
    <style type="text/css">

    #printable { display: none; }

    @media print
    {
        #non-printable { display: none; }
        #printable { display: block; }
    }
    </style>
</head>
<body>
    <div id="non-printable">
        Your normal page contents
    </div>

    <div id="printable">
        Printer version
    </div>
</body>

}

Answer 7

@media screen { #printOnly:{display:none;} }
@media print{ #printOnly:{display:block;} }

Answer 8

您需要媒体查询才能在打印和屏幕选项之间切换

private void btnLogin_Click(object sender, EventArgs e)
    {
        try
        {
            this.Hide();

            string Log_API = "http://api.retailbutton.co/WS/Service.php?Service=employeeLogin";
            if (LoginUser(Log_API))
            {
                logIn_Status = "true";
                GlolbalUtil.LogIn_Status = logIn_Status;
                frmDash frmDash = new frmDash();
                frmDash.Owner = this;
                frmDash.Show();
                txtUsername.Text = "";
                txtPassword.Text = "";
                //GlolbalUtil.accept_status = "1";
            }
            else
            {
                MessageBox.Show("Please Check Username and password");
                FrmLogin frmLogin = new FrmLogin();
                frmLogin.Owner = this;
                frmLogin.Show();
            }


        }

@media print {/ * for print option * /
