URL Parameters are not processed when opening in MS Edge

Okay, here's a weird issue for you guy sand gals.
I'm using a window.open tag in JS to open a .cfm file that will open in Excel (Report), however, the appended URL variable appears to change. It seems that the ? gets changed to an _ and thus the browser thinks its a text file and not a web page. Any Ideas??
window.open("amal_reports/rpt_change_indicator_notes.cfm?batch="+selBatch);
The URL should be
http://example.com/amal_reports/rpt_change_indicator_notes.cfm?batch=1160 but when the browser asks what do with the file it says
rpt_change_indicator_notes_cfm_batch=1160 and wants to open a text
file.
If I call the report directly in the URL without the form or JS stuff the same thing happens, conversely, if I remove the URl variable (?batch=1160) the report opens in Excel as expected but no data is populated because the batch number is missing.
So, to summarize, the browser is changing my .cfm link from js or directly in the browser to _cfm and thus it won't open in Excel as expected.

Okay, developer error! It looks as though checking the developers tool (F12) based upon theGleep suggestion, I found that my page was missing or couldn't find a variable. Once that was corrected the report open as expected.

Get Current Page number of Embedded pdf

I am planning to develop a webapp. The page will have an iframe on the left side and javascript form on right side. The iframe will be used to view pdfs from server.
I have been looking for ways to capture or get the current page number of the pdf being viewed in the iframe.
Is this possible?

One suggestion would be to try and use PDF.js, a PDF viewer that is built with HTML5. This might help you get around the need to use an iFrame to render the PDFs. But, if you need the iFrame for other reasons, then try looking at the PDF.js examples. As indicated on a previous stackoverflow thread, there are functions you could take advantage of:
PDFJS.getDocument('helloworld.pdf').then(function(pdf) {
// you can now use *pdf* here
pdf.getPage(1).then(function(page) {
// you can now use *page* here
});
});
Hope this helps the cause.

How can I *locally* save an .html file generated by javascript (running on a *local* .html page)?

So I've been researching this for a couple days and haven't come up with anything conclusive. I'm trying to create a (very) rudimentary liveblogging setup because I don't want to pay for something like CoverItLive. My process is: Local HTML file > Cloud storage (Dropbox/Drive/etc) > iframe on content page. All that works, and with some CSS even looks pretty nice despite the less-than-awesome approach. But here's the thing: the liveblog itself is made up of an HTML table, and I have to manually copy/paste the code for a new row, fill in the timestamp, write the new message, and save the document (which then syncs with the cloud and shows up in the iframe). To simplify the process I've made another HTML file which I intend to run locally and use to add entries to the table automatically. At the moment it's just a bunch of input boxes and some javascript to automate the timestamp and write the table row from the input data.
Code, as it stands now: http://jsfiddle.net/LukeLC/999bH/
What I'm looking to do from here is find a way to somehow export the generated table data to another .html file on my hard drive. So far I've managed to get this code...
if(document.documentElement && document.documentElement.innerHTML){
var a=document.getElementById("tblive").innerHTML;
a=a.replace(/</g,'<');
var w=window.open();
w.document.open();
w.document.write('<pre><tblive>\n'+a+'\n</tblive></pre>');
w.document.close();
}
}
...to open just the generated table code in a new window, and sure, I can save the source from there, but the whole point is to eliminate steps like that from the process.
How can I tell the page to save the generated code to a separate .html file when I click on the 'submit' button? Again, all of this happens locally, not on a server.
I'm not very good with javascript--and maybe a different language will be necessary--but any help is much appreciated.

I suppose you could do something like this:
var myHTMLDoc = "<html><head><title>mydoc</title></head><body>This is a test page</body></html>";
var uri = "data:application/octet-stream;base64,"+btoa(myHTMLDoc);
document.location = uri;
BTW, btoa might not be cross-browser, I think modern browsers all have it, but older versions of IE don't. AFAIK base64 isn't even needed. you might be able to get away with
var uri = "data:application/octet-stream,"+myHTMLDoc;
Drawbacks with this is that you can't set the filename when it gets saved

You cant do this with javascript but you can have a HTML5 link to open save dialogue:
<a href="pageToDownload.html" download>Download</a>
You could add some smarts to automate it on the processed page after the POST.

Simple answer, you can't.
JavaScript is restricted to perform such operations due to security reasons.
The best way to accomplish that, would be, to call a server page that would write
the new file on the server. Then from javascript perform a POST request to the
server page passing the data you want to write to the new file.
If you want the user to save the page to it's file system, this is a different
problem and the best approach to accomplish that, would be to, notify the user/ask him
to save the page, that page could be your new window like you are doing w.open().
Let me do some demonstration for you:
//assuming you know jquery or are willing to use it :)
var html = $("#tblive").html().replace(/</g, '<');
//generating your download button
$.post('generate_page.php', { content: html })
.done(function( data ) {
var filename = data;
//inject some html to allow user to navigate to the new page (example)
$('#tblive').parent().append(
'Check your Dynamic Page!');
// you data here, is the response from the server so you can return
// your new dynamic page file name here.
// and maybe to some window.location="new page";
});
On the server side, something like this:
<?php
if($_REQUEST["content"]){
$pagename = uniqid("page_", true) . '.html';
file_put_contents($pagename, $_REQUEST["content"]);
echo $pagename;
}
?>
Some notes, I haven't tested the example, but it works in theory.
I assume that with this the effort to implement it should be minimal, assuming this solves your problem.

A server based solution:
You'll need to set up a server (or your PC) to serve your HTML page with headers that tell your browser to download the page instead of processing the HTML markup. If you want to do this on your local machine, you can use software such as WAMP (or MAMP for Mac or LAMP for Linux) that is basically a web server in a .exe. It's a lot of hassle but it'll work.

How can i convert html content(having images also) to a document file using javascript?

I am trying to capture some content of a div in html (both text and images) and I want to convert that to a doc file so that i can mail it. I am using html5 javascript and jQuery.
I have to convert it on the client side.

Here's your solution http://www.phpdocx.com/. You'll need a server side language to do that, the example uses PHP.

Since you have such strict requirements:
Email the user a link with a version of the report you want the user to see when they open the doc.
Tell the user to open MS Word, Click File, Open, Then paste the link in.
The user can then save it as a .doc file where ever they want.
Note: By the way this is the wrong answer, Although you've already turned it down, slash197's answer is the correct way to do this and the way i would normally suggest.
That or just email the report as html.

Retrieve text from external HTML/asp page with JavaScript

I am using an external asp page (On the company's server - not related to me beside the fact that I'm using it for my job).
The asp page has one query in it, I'm writing something in it and it gives me some information.
In the information there is a certain line with constant header (let's assume 'HEADER'), I want to build an HTA that pulls the line that contains 'HEADER' to my HTA and display only this line.
I think that this isn't possible without any server interaction, but I'm asking anyway.
Can someone think of a way doing it?
Thanks,
Rotem

You can use an Ajax request to pull data from that page. The javascript page needs to be on the same server as the page you want to pull data from because of cross site scripting prevention in most browsers. Here is a good place to start: http://www.w3schools.com/ajax/ajax_intro.asp

Ok, I made something with JavaScript, using Telnet.
It isn't working for all sites, when I'll be at work I'll check it, but I think this will do the job.
The code:
<script type="text/javascript">
var WshShell = new ActiveXObject("WScript.Shell");
WshShell.Run("telnet -fc:/telnetlog.txt www.google.com 80"); // This will save me the source file + minor junk!
setTimeout("WshShell.SendKeys('GET / HTTP/1.0~~')",1000); // Enter the command it telnet </script>
Thanks for the brainstorming,
Rotem
