Javascript事件处理程序打印 [英] Javascript Event Handler for Print

问题描述

在javascript中有一个事件，您可以在调用文件>>打印时收听吗？它是什么？还有 - 打印完成时有处理程序吗？这是什么？

或者如果有更好的方法来做这样的一些其他手段，如样式表，你怎么做？

解决方案

不同的样式表

您可以指定其他

 < link rel =stylesheettype =text / cssmedia =printhref = print.css/> 
< link rel =stylesheettype =text / cssmedia =screenhref =main.css/> 
  

一种样式表

提到的kodecraft，您也可以使用@media块将样式放入同一个文件。

  @媒体打印{
 div.box {
 width：100px; 
} 
} 
 
 @media screen {
 div.box {
 width：400px; 
} 
} 
  

I am trying to alter style at print-time:

Is there an event in javascript that you can listen for for when file>>print is called? What is it? Also - is there a handler for when printing is finished? What is it?

or if there is a better way to do this with some other means, such as style sheets, how do you do that?

解决方案

Different Style Sheets

You can specify a different stylesheet for printing.

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

One Style Sheet

As kodecraft mentioned, you can also put the styles into the same file by using the @media block.

@media print {
    div.box {
        width:100px;
    }
}

@media screen {
    div.box {
        width:400px;
    }
}
