实际的问题是在一个新的窗口，为PDF页面显示PDF数据（arraybuffer）。 PDF不应该被下载到TEMP文件夹。结果
脚步：
我正在从一个RESTful AJAX调用arraybuffer响应。
转换，要在BLOB JS。
BLOB不支持IE8，但我上面的blob构造补充说。现在我面临的问题在window.URL因为我不能够使用到BOLB转换为文档的网址window.URL.createObjectURL（BLOB）
请采取以下code一看：
searchService.viewDocument（的docId）
.success（功能（数据，状态，头，配置）{
如果（window.Blob）{
VAR BLOB =新的Blob（[数据] {类型：应用程序/ PDF}）; //如果BLOB构造增加，这将IE8的工作 的console.log（窗口+窗口）;
的console.log（window.URL+ window.URL）;
的console.log（window.webkitURL+ window.webkitURL）;
的console.log（window.mozURL+ window.mozURL）;
的console.log（window.msURL+ window.msURL）; VAR URLLink = window.URL || window.webkitURL || window.mozURL || window.msURL;
的console.log（'URLLink ='+ URLLink）; //这是在其他浏览器Chrome和IE8 IE11 code ++工程null或undefined VAR fileURL = URLLink.createObjectURL（BLOB）;
$ scope.content = $ sce.trustAsResourceUrl（fileURL）; // AngularJS code VAR pdfWindow = window.open（，PDF浏览，宽= 1833，高度= 1000）;
VAR pdfHtmlData ='＆LT; HEAD＆GT;＆LT;标题＆GT; PDF查看＆LT; /标题＆GT;＆LT; /头＆GT;＆LT;身体GT;＆LT; DIV＆GT;＆LT;对象宽度=1833HEIGHT =1000数据=+ $ scope.content +'类型=应用/ PDF＆GT;＆LT; /对象＆gt;＆LT; / DIV＆GT;＆LT; /身体GT;';
pdfWindow.document.write（pdfHtmlData）;
}其他{
的console.log（不支持viewDocument BLOB。）; } }）。错误......
您可以使用window.location的，它包含了你需要的一些信息。
使用此code：
window.location.href
您可以看到该对象的样本波纹管
{散列：，主持人：st.msc.ir，主机名：domain.com中，href：HTTP：// ......，路径：/login.aspx，端口： 协议：HTTP：搜索：RETURNURL = ...}
如果你想没有任何code更改您的code之前加入这行来解决你的问题。
window.URL = window.URL window.URL：window.location.href;
I am facing problem in using window.URL in IE8. Could someone please help. I am trying to get window.URL working in IE8. Please following code.
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type">
</head>
<body>
<p>This text should be red.</p>
<script>
window.Blob = Blob = function (b) {

console.log('Check window.URL => '+window.URL );
console.log('Check window.Blob => '+window.Blob );
myBlob = new Blob(['body { color: red; }'], {type: 'text/css'});

Actual problem is displaying PDF data (arraybuffer) on a new window as a PDF page. PDF should not be downloaded to TEMP folder.
steps:
I am getting arraybuffer response from a RESTful AJAX call.
Converting that to BLOB in JS.
BLOB is not supported in IE8 but I added above blob constructor. Now I am facing problem in window.URL as I am not able to convert BOLB to doc URL using window.URL.createObjectURL(blob)
Please take a look in following code:
searchService.viewDocument(docId)
.success(function(data, status, headers, config) {
if (window.Blob) {
var blob = new Blob([data], {type: "application/pdf"}); //IF BLOB constructor added this will work for IE8
console.log("window "+window);
console.log("window.URL "+window.URL);
console.log("window.webkitURL "+window.webkitURL);
console.log("window.mozURL "+window.mozURL);
console.log("window.msURL "+window.msURL);
var URLLink = window.URL || window.webkitURL || window.mozURL || window.msURL;
console.log('URLLink ='+URLLink ); // this is NULL OR UNDEFINED in IE8 Code works in other browsers like Chrome and IE11
var fileURL = URLLink.createObjectURL(blob);
$scope.content = $sce.trustAsResourceUrl(fileURL); //AngularJS code
var pdfWindow = window.open("", "PDF View", "width=1833, height=1000");
var pdfHtmlData = '<head><title>PDF View</title></head><body><div ><object width="1833" height="1000" data="' + $scope.content + '" type="application/pdf"></object></div></body>';
pdfWindow.document.write(pdfHtmlData);
}else{
console.log("viewDocument BLOB not supported.");
}
}).error......
you can use window.location ,it contains some information that you need.
Use this code: window.location.href
you can see a sample of this object bellow
{hash: "", host: "st.msc.ir", hostname: "domain.com", href: "http://...", pathname: "/login.aspx", port: "", protocol: "http:", search: "?ReturnUrl=..."}
If you want to solve your problem without any code changing add this line before your code
window.URL=window.URL?window.URL:window.location.href;
