推荐答案

解决您问题的以下部分:

Addressing the following part of your question:

在打印"中也打印此页已打印.

in the print "print this page also printed .

我怎样才能隐藏它?

创建一个新的样式表(在本例中，我将其命名为print.css")并将其包含在您的 HTML 中，如下所示:

Create a new stylesheet (in this example, I've named it "print.css") and include it in your HTML as follows:

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

注意 media="print"——这意味着样式表只会在打印页面时使用.

Note the media="print"—this means the stylesheet will only be used when printing the page.

接下来为您的 元素分配一个类，以便我们可以在 CSS 中引用它:

Next assign a class to your <a> element so that we can reference it in CSS:

<a href="javascript:window.print()" class="noPrint">Print this Page</a>

最后，在您的 CSS 文件中，包含以下规则:

Finally, in your CSS file, include the following rule:

.noPrint {
    display: none;
}

现在打印此页面"链接不应出现在页面的打印版本中.

Now the "Print this Page" link shouldn't appear in the printed version of your page.
