嵌入PDF一个ASP.NET页面上 [英] Embed a PDF on a ASP.NET page
问题描述
我试着去嵌入到我的页面的PDF，但PDF只是不加载。我检查了这是正确的文件路径。
Im trying to embed a PDF on to my page, but the PDF just does not load. I have checked the file path which is correct.
当第一次加载页面，我得到了一个空白的灰色领域的嵌入，但是当我点击嵌入，我得到这个（其中保持这样的）：
When the page first loads, I get a blank grey embed field, however when I click on the embed, I get this (which stays like this):
<script>
var selected_doc_ref = "";
function getPDF() {
//selected_doc_ref = "395";
var DV_pdf_path = "../../../Document_Viewer/Risk_Assessment/RISK ASSESSMENT 1024.pdf";
var pdf = document.getElementById("pdf");
var clone = pdf.cloneNode(true);
clone.setAttribute('src', DV_pdf_path);
pdf.parentNode.replaceChild(clone, pdf)
}
</script>
<body onload="getPDF()">
<embed id="pdf" style="border-radius: 10px;position: relative;top:0;right:0;left:0;bottom:0;width:100%;height:620px;"/>
任何想法，我错了？
Any ideas where I am going wrong?
感谢
推荐答案
由于浏览器不刷新嵌入标签，当你添加的src 属性添加到＆LT;＆嵌入GT; 页面加载后的标签，你有2个选项：
As the browser does not refresh the embed tag when you add the src attribute to the <embed> tag after page load you have 2 options:
- 设置的
＆LT src属性;嵌入＆GT;标记直接，因此可从一开始。你可以设置的src通过背后或作为一个静态值code。 -
在您的JavaScript，加上整个
＆LT;嵌入＆GT;的getPDF内标签（）功能而不是仅仅属性的src：
- Set the src attribute on the
<embed>tag directly so it is available from the beginning on. You could set thesrcthrough code behind or as a static value. In your javascript, add the whole
<embed>tag inside thegetPDF()function instead of just the attributesrc:
var e = document.createElement('embed');
e.attributes['src'] = src;
e.attributes['style'] = "border-radius: 10px;position: relative;top:0;right:0;left:0;bottom:0;width:100%;height:620px;";
document.getElementById("pdfContainer").appendChild(e);
假设你有，你要放置＆LT ID为pdfContainer一个元素;嵌入方式＆gt;在标记
Assuming that you have a element with id "pdfContainer" where you want to place the <embed> tag inside.
