硬拷貝中的打印按鈕

Question

我有一個保存在this fiddle中的javascript腳本。但我無法從硬拷貝中刪除打印按鈕。是否有其他方法可以刪除打印按鈕？下面的腳本給出：

function printpage() 
{ 
var data = 'Sample Report<br />Sample Report<br />Sample Report<br />'; 
    var data = data+'<br/><button onclick="window.print()" class="noprint">Print the Report</button>';  
    myWindow=window.open('','','width=800,height=600'); 
    myWindow.innerWidth = screen.width; 
    myWindow.innerHeight = screen.height; 
    myWindow.screenX = 0; 
    myWindow.screenY = 0; 
    myWindow.document.write(data); 
    myWindow.focus(); 
} 

和HTML是

<input type="button" value="Print Preview" onclick="printpage()" />

添加樣式聲明預覽窗口：

function printpage() { 
    var data = 'Sample Report<br />Sample Report<br />Sample Report<br />'; 
    data += '<br/><button onclick="window.print()" class="noprint">Print the Report</button>'; 
    data += '<style type="text/css" media="print"> .noprint {visibility: hidden;} </style>'; 
    myWindow = window.open('', '', 'width=800,height=600'); 
    myWindow.innerWidth = screen.width; 
    myWindow.innerHeight = screen.height; 
    myWindow.screenX = 0; 
    myWindow.screenY = 0; 
    myWindow.document.body.innerHTML = data; 
    myWindow.focus(); 
}
