Make any link with .pdf open in new window with jQuery?
提问by Digi Jeff
How can I have all links with a .pdffile extension open in a new window using jQuery? I need to change this:
如何.pdf使用 jQuery 在新窗口中打开所有带有文件扩展名的链接？我需要改变这个：
<a href="domain.com/pdf/parkingmap.pdf">parking map</a>
In to this:
对此：
<a href="domain.com/pdf/parkingmap.pdf" target="_blank">parking map</a>
All files are in a /pdffolder if that helps.
/pdf如果有帮助，所有文件都在一个文件夹中。

To achieve this you can select any aelement which has a hrefproperty ending with .pdf, and add a target="_blank"attribute to it. Try this:
为此，您可以选择a具有以href结尾的属性的任何元素.pdf，并target="_blank"为其添加属性。尝试这个：
$(function() {
$('a[href$=".pdf"]').prop('target', '_blank');
});

<a onclick=ViewPdf(test.pdf) href="">
function ViewPdf(FileName) {
var url = '../Home/GetPDF?fileName=' + FileName;
window.open(url, '_blank');
}Now write ActionResult like below
现在像下面这样写 ActionResult
public ActionResult GetPDF(string fileName)
{
try
{
byte[] fileData = System.IO.File.ReadAllBytes(Functions.GetConfigValue("CDXFilePath") + fileName);
string resultFileName = String.Format("{0}.pdf", fileName);
Response.AppendHeader("Content-Disposition", "inline; filename=" + resultFileName);
return File(fileData, "application/pdf");
}
catch
{
return File(Server.MapPath("/Content/") + "FileNotFound.html", "text/html");
}
}

One way, assuming you want links notending in pdfto open in the same page:
一种方法，假设您希望链接不以在pdf同一页面中打开为结尾：
$('a').click(
function(e){
e.preventDefault();
if (this.href.split('.').pop() === 'pdf') {
window.open(this.href);
}
else {
window.location = this.href;
}
});

jQuery one-liner :
jQuery 单线：
$('a[href$=".pdf"]').attr('target','_blank');
Also in vanilla Javascript :
同样在香草 Javascript 中：
[].filter.call(document.querySelectorAll('a'), function(a){
return a.href.match('\.pdf$') ? a.target = '_blank' : 0;
});
Or maybe :
或者可能 ：
var anchors = document.body.getElementsByTagName('a');
for (var i = 0; i < anchors.length; i++) {
if(anchors[i].getAttribute('href').match('\.pdf$') {
anchors[i].setAttribute('target', '_blank');
}
}
