问题描述
我有一个使用在浏览器中创建PDF的应用程序。我想在另一个标签页/窗口中显示这个pdf。
function open_data_uri_window(url){
var html =' < html> +
< style> html,body {padding:0;保证金:0; } iframe {width:100%;身高:100% border = 0;}< / style>'+
'< body>'+
'< p>新的观看者< / p> +
< iframe type = application / pdfsrc ='+ url +'>< / iframe>'+
'< / body>< / html>';
var a = window.open(about:blank,Zupfnoter);
a.document.write(html);
.document.close();
$ b 它在Chrome(60.0.3112.90)中工作正常,但在Firefox(54.0 .1 64位MacOs)。那里的窗口挂起。
解决方案原因是PDF.js(第331行)尝试从url中提取建议的文件名。这个正则表达式根据dataurl挂起。
解决方法是在datauri字符串中指定一个名称,以便始终找到一个可接受的名称,如注释1
函数open_data_uri_window(url){
var url_with_name = url.replace(data:application / pdf;,data:application / pdf; name = myname.pdf;)
var html ='< html>'+
'< style> ; html,body {padding:0;保证金:0; } iframe {width:100%;身高:100% border = 0;}< / style>'+
'< body>'+
'< p>新的观看者< / p> +
< iframe type = application / pdfsrc ='+ url_with_name +'>< / iframe>'+
'< / body>< / html>';
var a = window.open(about:blank,Zupfnoter);
a.document.write(html);
.document.close();
code
提示:Chrome浏览器的内建查看器不支持指定的名称
I have an app which creates pdf in the browser using jspdf. I want to show this pdf in another tab/window.
function open_data_uri_window(url) {
var html = '<html>' +
'<style>html, body { padding: 0; margin: 0; } iframe { width: 100%; height: 100%; border: 0;} </style>' +
'<body>' +
'<p>new viewer</p>' +
'<iframe type="application/pdf" src="' + url + '"></iframe>' +
'</body></html>';
var a = window.open("about:blank", "Zupfnoter");
a.document.write(html);
a.document.close();
}
It works fine in chrome (60.0.3112.90) but not on Firefox (54.0.1 64 bit MacOs). There the window hangs.
解决方案 Reason is that PDF.js (line 331) tries to extract a suggested filename from the url. This regular expression hangs depending on the dataurl.
Solution is to specify a name in the datauri string, so that an accepted name is always found, as mentioned in comment 1 of Is there any way to specify a suggested filename when using data: URI?
function open_data_uri_window(url) {
var url_with_name = url.replace("data:application/pdf;", "data:application/pdf;name=myname.pdf;")
var html = '<html>' +
'<style>html, body { padding: 0; margin: 0; } iframe { width: 100%; height: 100%; border: 0;} </style>' +
'<body>' +
'<p>new viewer</p>' +
'<iframe type="application/pdf" src="' + url_with_name + '"></iframe>' +
'</body></html>';
var a = window.open("about:blank", "Zupfnoter");
a.document.write(html);
a.document.close();
}
Hint: The specified name is not respected by Chrome's builtin viewer
