这是我使用 iframe 在 JavaScript 中打印 pdf 文件的代码。但我无法打印任何事情都没有发生，但此代码在谷歌浏览器中完美运行。在 IE8 中不起作用。ContentLoaderDiv 是 html 的划分。请帮我..
When I print a PDF document from our application which uses Java script to print instead of adobe Reader print dialog the browser print dialog is invoked.
当我从使用 Java 脚本打印而不是 adobe Reader 打印对话框的应用程序打印 PDF 文档时，将调用浏览器打印对话框。
Have anyone seen this problem? How to invoke the Adobe reader printer dialog instead of browser print dialog?
有没有人见过这个问题？如何调用 Adobe reader 打印机对话框而不是浏览器打印对话框？
function printPdf() {
var ContentLoaderDiv = document.getElementById('ContentLoaderDiv');
ContentLoaderDiv.innerHTML = "";
ContentLoaderDiv.innerHTML = '<div id="pdfdiv" style="position: relative;"><iframe id="frame1" height="800" width="700" src="' + document.getElementById("<%= hdnPDFPathForObject.ClientID %>").value + "print.pdf#scrollbar=1&toolbar=1&statusbar=0&messages=0&navpanes=1" + '"' + " /></iframe></div>";
frame1.focus();
frame1.print();
}
}

Try this one:
试试这个：
function PdfUtil(url) {
var iframe;
var __construct = function(url) {
iframe = getContentIframe(url);
}
var getContentIframe = function(url) {
var iframe = document.createElement('iframe');
iframe.src = url;
return iframe;
}
this.display = function(parentDomElement) {
parentDomElement.appendChild(iframe);
}
this.print = function() {
try {
iframe.contentWindow.print();
} catch(e) {
throw new Error("Printing failed.");
}
}
__construct(url);
}
And you can use it as follows:
您可以按如下方式使用它：
var pdf = new PdfUtil(PDF_URL);
pdf.display(document.getElementById('placeholder'));
document.getElementById('printBtn').onclick = function() {
pdf.print();
}
Obviously, though PDF_URLhere is a "constant", in your case it should most probably be generated.
显然，虽然PDF_URL这里是一个"constant"，但在您的情况下，它很可能是生成的。
Works perfectly with IE8 and Chrome (should work also with other browsers). Also, the OO approach makes it far more maintainable and/or reusable. Slight modifications to the actual logic might still be required to fit all your needs.
与 IE8 和 Chrome 完美配合（也应与其他浏览器配合使用）。此外，OO 方法使其更易于维护和/或可重用。可能仍需要对实际逻辑稍作修改以满足您的所有需求。

I have struggled a bit to find a solution that works for both IE and Chrome. This works for me:
我一直在努力寻找适用于 IE 和 Chrome 的解决方案。这对我有用：
$(function() {
var ua = window.navigator.userAgent;
var msie = ua.indexOf('MSIE ');
var trident = ua.indexOf('Trident/');
var edge = ua.indexOf('Edge/');
var url = '/url/to/file.pdf';
var pdf ='';
var style = 'position:fixed; top:0px; left:0px; bottom:0px; right:0px; width:100%; height:100%; border:none; margin:0; padding:0; overflow:hidden;';
if(msie > 0 || trident > 0 || edge > 0){
pdf = '<object data="' + url + '" name="print_frame" id="print_frame" style="' + style + '" type="application/pdf">';
}
else{
pdf ='<iframe src="' + url + '" name="print_frame" id="print_frame" style="' + style + '"></iframe>';
}
$(document.body).append(pdf);
setTimeout(function(){
window.frames["print_frame"].focus();
window.frames["print_frame"].print();
},2000);
});
...cheers.
...干杯。
