我如何在iframe中设置base64 pdf的文件名? [英] How can I set the filename for base64 pdf in iframe?
问题描述
我在base64中有一份PDF报告,我想显示嵌入在HTML页面中的文件。要做到这一点,我使用的iFrame和工作,但问题是,我不能设置PDF的名称,以便下载时将它保存与分配的名称。
这是我的代码:
$ b $可以设置文件名吗?如果是,我该怎么办? b
结果:
预览PDF
当我尝试下载文件时,要保存的名称是download.pdf
保存对话框
我尝试了不同的方法,但也无法使用:
添加属性 下载=文件.pdf / strong> var iFrameBlock = $(< iframe>)。attr({src:base64file_encode, width:100%,height:100%,frameborder:0,download:filename.pdf}); 我试图改变iframe中的值,但我可以找到正确的属性,并且Chrome否认了这一行为。
var iframe = $(iframe)[0]; var iframeDocument = iframe.contentDocument || iframe.contentWindow.document; //这里我想是文件名$(iframeDocument).find(viewer-pdf-toolbar)的标签;
然而,
,我想阻止使用任何其他库。
感谢您的时间
解决方案 iframe
元素不能做到这一点,但作为替代方案,您可以添加锚标签。 <$ ($ {$ b $id:iframe,
src:base64file_encode,$ b)pre>
var iFrameBlock = $(< iframe> $ bwidth:100%,
height:100%,
frameborder:0
});
var aTag = $(< a> Dwonload< / a>)。attr({
href:base64file_encode,
download:yourName.pdf
});
$(#previewPDF)。html(iFrameBlock);
aTag.insertAfter($(#iframe));
问候,KJ。
I have a report PDF in base64, I want to show the file embedded in the HTML page. To do this I use the iFrame and works, but the problem is that I can't set the name of the PDF so that when downloaded it will be saved with the name assigned.
Can I set the filename?, if yes, how can I do it?
this is my code:
var iFrameBlock = $("<iframe>").attr({
"src": base64file_encode,
"width": "100%",
"height": "100%",
"frameborder": "0"
});
$("#previewPDF").html(iFrameBlock);
The result: Preview of PDF
And when I try download the file, the name to be saved is "download.pdf" Save dialog
I tried differents ways, but do not work either:
Adding attribute download="filename.pdf"
var iFrameBlock = $("<iframe>").attr({ "src": base64file_encode, "width": "100%", "height": "100%", "frameborder": "0", "download": "filename.pdf" });
I tried to change the value inside the iframe, but I could find the correct attribute and the Chrome denied the action.
var iframe = $("iframe")[0]; var iframeDocument = iframe.contentDocument || iframe.contentWindow.document; //here I suppose is the label of the filename $(iframeDocument).find("viewer-pdf-toolbar");
However, I want prevent use any other library.
Thank you for your time
The iframe
element can't do that, but as an alternative you can add anchor tag.
var iFrameBlock = $("<iframe>").attr({
"id": "iframe",
"src": base64file_encode,
"width": "100%",
"height": "100%",
"frameborder": "0"
});
var aTag = $("<a>Dwonload</a>").attr({
"href": base64file_encode,
"download": "yourName.pdf"
});
$("#previewPDF").html(iFrameBlock);
aTag.insertAfter($("#iframe"));
