如何打印pdf？ [英] How to print a pdf?

问题描述

我有一个pdf网址，嵌入在iframe的矩形区域中。我想点击一个按钮打印它。我的代码如下所示：

I have a pdf url, embedded in a rectangular area of an iframe. I am trying to print it on click of a button . My code looks like this :

要打印的JavaScript：

function printPDF(pdfUrl)
{
var w = window.open(pdfUrl);
w.print();
w.close();
}

HTML代码：

<table>
<tr>
<td><input type="submit"  value="Print"
name="Submit" id="printbtn"
onclick="printPDF('http://www.irs.gov/pub/irs-pdf/fw4.pdf')" /></td>
</tr>

现在在MF中就是这样：

Now in MF it is coming like this :

问题，它在chrome和IE中无法正常工作。我有chrome 20和IE 8.在chrome中，打印窗口被加载到一个新选项卡中（这没关系）但是pdf没有在预览中加载。在IE中，pdf刚刚在新选项卡中打开，并且没有出现打印提示。

The problem , its not working properly in chrome and IE. I have chrome 20 and IE 8. In chrome the print window gets loaded in a new tab(which is ok) but pdf does not get loaded in preview. In IE the pdf just gets opened in a new tab and print prompt does not come up.

在任何人问我之前，pdf可能具有固有的打印功能。但我正在处理的pdfs需要一个打印按钮。人们，请帮助我。是否有解决方案，适用于所有3个浏览器。

Before any one asks me, pdf might have inherent print functionality. but the pdfs that i am processing need to have a print button. People, kindly help me out here. Is there a solution, which is applicable in all the 3 browsers .

推荐答案

伙计们，刚刚得到一个解决方案，适用于我。

Folks, just got a solution , which works fine for me .

function printPage(htmlPage)
{
    var w = window.open("about:blank");
    w.document.write(htmlPage);
    if (navigator.appName == 'Microsoft Internet Explorer') window.print();
    else w.print();
}

所以，如果它是MSIE，那么我们可以使用：window.print （）;

So, if it is MSIE, then we can just use : window.print();
