Is there a way to get Index HTML file name on default server location (Javascript or jQuery)

I'm trying to find a way to get the name of the current HTML file from URL (or any other possible way. It works most of the time, except for the case when the URL doesn't display the file name :
Works when : http://localhost:8080/Index.html
Doesn't work when : http://localhost:8080/ (hosting server will display index page that way on load).
The following function is the one I currently used. It is inspired from few other questions on StackOverflow talking about getting the filename from the complete URL.
function GetOtherLanguageLink(lang){
var pagename = window.location.pathname.substring(location.pathname.lastIndexOf("/") + 1);
pagename_split = pagename.split('.');
if (lang == "fr"){
return pagename_split[0] + "_en." + pagename_split[1];
}
else if (lang == "en"){
return pagename.replace("_en","");
}
else{
return pagename;
}
}
It is pretty simple, for Index.html it returns Index_en.html and vice versa.
When the URL doesn't have a filename, I get _en.undefined.
Is there some other way I could do that to get it work?
PS : if things are unclear, comment (I usually speak french so may not be clear).
Thanks in advance!

What's the best method to EXTRACT product names given a list of SKU numbers from a website?

I have a problem.
I have a list of SKU numbers (hundreds) that I'm trying to match with the title of the product that it belongs to. I have thought of a few ways to accomplish this, but I feel like I'm missing something... I'm hoping someone here has a quick and efficient idea to help me get this done.
The products come from Aidan Gray.
Attempt #1 (Batch Program Method) - FAIL:
After searching for a SKU in Aidan Gray, the website returns a URL that looks like below:
http://www.aidangrayhome.com/catalogsearch/result/?q=SKUNUMBER
... with "SKUNUMBER" obviously being a SKU.
The first result of the webpage is almost always the product.
To click the first result (through the address bar) the following can be entered (if Javascript is enabled through the address bar):
javascript:{document.getElementsByClassName("product-image")[0].click;}
I wanted to create a .bat file through Command Prompt and execute the following command:
firefox http://www.aidangrayhome.com/catalogsearch/result/?q=SKUNUMBER javascript:{document.getElementsByClassName("product-image")[0].click;}
... but Firefox doesn't seem to allow these two commands to execute in the same tab.
If that worked, I was going to go to http://tools.buzzstream.com/meta-tag-extractor, paste the resulting links to get the titles of the pages, and export the data to CSV format, and copy over the data I wanted.
Unfortunately, I am unable to open both the webpage and the Javascript in the same tab through a batch program.
Attempt #2 (I'm Feeling Lucky Method):
I was going to use Google's &btnI URL suffix to automatically redirect to the first result.
http://www.google.com/search?btnI&q=site:aidangrayhome.com+SKUNUMBER
After opening all the links in tabs, I was going to use a Firefox add-on called "Send Tab URLs" to copy the names of the tabs (which contain the product names) to the clipboard.
The problem is that most of the results were simply not lucky enough...
If anybody has an idea or tip to get this accomplished, I'd be very grateful.

I recommend using JScript for this. It's easy to include as hybrid code in a batch script, its structure and syntax is familiar to anyone comfortable with JavaScript, and you can use it to fetch web pages via XMLHTTPRequest (a.k.a. Ajax by the less-informed) and build a DOM object from the .responseText using an htmlfile COM object.
Anyway, challenge: accepted. Save this with a .bat extension. It'll look for a text file containing SKUs, one per line, and fetch and scrape the search page for each, writing info from the first anchor element with a .className of "product-image" to a CSV file.
#if (#CodeSection == #Batch) #then
#echo off
setlocal
set "skufile=sku.txt"
set "outfile=output.csv"
set "URL=http://www.aidangrayhome.com/catalogsearch/result/?q="
rem // invoke JScript portion
cscript /nologo /e:jscript "%~f0" "%skufile%" "%outfile%" "%URL%"
echo Done.
rem // end main runtime
goto :EOF
#end // end batch / begin JScript chimera
var fso = WSH.CreateObject('scripting.filesystemobject'),
skufile = fso.OpenTextFile(WSH.Arguments(0), 1),
skus = skufile.ReadAll().split(/\r?\n/),
outfile = fso.CreateTextFile(WSH.Arguments(1), true),
URL = WSH.Arguments(2);
skufile.Close();
String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ''); }
// returns a DOM root object
function fetch(url) {
var XHR = WSH.CreateObject("Microsoft.XMLHTTP"),
DOM = WSH.CreateObject('htmlfile');
WSH.StdErr.Write('fetching ' + url);
XHR.open("GET",url,true);
XHR.setRequestHeader('User-Agent','XMLHTTP/1.0');
XHR.send('');
while (XHR.readyState!=4) {WSH.Sleep(25)};
DOM.write(XHR.responseText);
return DOM;
}
function out(what) {
WSH.StdErr.Write(new Array(79).join(String.fromCharCode(8)));
WSH.Echo(what);
outfile.WriteLine(what);
}
WSH.Echo('Writing to ' + WSH.Arguments(1) + '...')
out('sku,product,URL');
for (var i=0; i<skus.length; i++) {
if (!skus[i]) continue;
var DOM = fetch(URL + skus[i]),
anchors = DOM.getElementsByTagName('a');
for (var j=0; j<anchors.length; j++) {
if (/\bproduct-image\b/i.test(anchors[j].className)) {
out(skus[i]+',"' + anchors[j].title.trim() + '","' + anchors[j].href + '"');
break;
}
}
}
outfile.Close();
Too bad the htmlfile COM object doesn't support getElementsByClassName. :/ But this seems to work well enough in my testing.

Download zip using jszip in Sharepoint

Hi I am looking for solutions insanely for almost 2 days.I have sharepoint library where multiple word docs uploaded.Using javascript JSZip I like to pass sharepoint file urls into it.Is this possible ?
I am getting each file server relative URL by ecmascript.Now I would like to do something like this:
function create_zip() {
debugger
var zip = new JSZip();
zip.add("http://myspsite/shareddoc/a/test.docx", "\n"); //this is hardcoded for testing??here I have file url
//zip.add("hello2.txt", "Hello Second World\n");
content = zip.generate();
location.href = "data:application/zip;base64," + content;
}
Any pointers or how I proceed from here?
Thanxs.

It´s insanely but interesting. Could works. Creating a button and calling the library and the script, I´m sure of that.
or, try this: http://techtrainingnotes.blogspot.com.ar/2010/05/sharepoint-2010-windows-explorer-view.html
This is more simple.

exchange variables between html files in javascript

I am trying to share variables between two html pages. I am only using javascript and HTML5 to develop a windows 8 app. Based on an image which a user clicks on one page, I want a div on a second page to be populated with that image. Any ideas?
When I click on the image, I am currently calling the following function:
function imageClick(url) {
//var id = parsed.ClientID;
//window.location= url + "?" + id
window.location = url;
}
Then in my html file, I have this line:
<img onclick="imageClick('pages/page2/page2.html')"
data-win-bind="src:image" style="width: 133px; height: 125.5px;">
I was thinking of getting that id in the next page's url (if I were to uncomment the commented lines above) but it's a bit hackky and I don't actually know how to go about executing the retrieval of that on the next page..
Is there a more efficient and easy way of doing this in javascript? Like an equivalent of sessions in php or something?

Javascript does not have session variables because it runs on the client side. You can use URL parameters and cookies in order to achieve the same results.
You can get the URL parameter by using this function:
http://ziemecki.net/content/javascript-parsing-url-parameters

Add the link to the image to the query part of the url when they click. Something like you had in the comment, assuming you don't have a query part already:
function imageClick(url) {
//var id = parsed.ClientID;
window.location= url + "?src=" + url.src;
//window.location = url;
}
The other page can use window.location.search to extract it, strip off the src=. The code would look something like this:
var src = window.location.search;
if (src.indexOf("src=") == 0) {
src = src.substring(4);
}
newPageImageElement.src = src;
Where newPageImageElement is the <img> where you want to display the picture on the second page.

How should I create relative paths in javascript using MVC3?

I am having some difficulty aligning my paths without a hardcode in javascript. I am running an asp.net MVC3 web application.
If my path is of the form
var url = 'http://serverNameHardcode/websiteNameHardcode/service/service?param1=' + param;
Then things work fine when I do
$.get(url,
{},
function (data) {alert('callback success');},'json');
I would like to create a relative path. I tried
var url = 'service/service?param1=' + param;
And this works when I run locally and also in Firefox, but not in IE7. When I publish to the server without the hardcode the callback never fires. I know MVC-3 adds some complexity to routing, but I do not know if it applies to this situation; so, I marked this question as such.
How should I setup my path so I don't need hardcodes?

Just write out the app path as a global js variable from your master view, then compose links as
APPPATH + "path/whatever"

Just had to solve this for one of my jQuery plugins, where it is preferable not to modify anything global (i.e. outside the scope of the plugin use) so I had to disregard the marked answer.
I also found that because I host DEV locally in IIS I could not use a root-relative path (as localhost is not the root).
The solution I came up with extended what I had already started with: a data-controller attribute specifying which controller to use in the element I am applying my plugin to. I find it preferable to data-drive the controller names so the components can be more easily reused.
Previous:
<div data-controller="Section">
Solution:
<div data-controller="#Url.Content("~/Section")">
This injects the server root (e.g. /Test.WindowsAzure.Apr2014/ before the controller name so I wind up with /Test.WindowsAzure.Apr2014/Section which is perfect for then appending actions and other parameters as you have. It also avoids having an absolute path in the output (which takes up extra bytes for no good reason).
In your case use something like:
// Assuming $element points to the element your plugin/code is attached to...
var baseUrl = $element.data('controller');
var url = baseUrl + '/service?param1=' + param;
Update:
Another approach we now use, when we do not mind injecting a global value, is Razor-inject a single global JavaScript variable onto window in the layout file with:
<script>
window.SiteRoot = "#Url.Content("~/")";
</script>
and use it with
var url = window.SiteRoot + '/service?param1=' + param;

One option:
var editLink = '#Url.Action("_EditActivity", "Home")';
$('#activities').load(editLink + "?activityID=" + id);
another example:
var actionURL = '#Url.Action("_DeleteActivity", "Home")';
$('#activities').load(actionURL + "?goalID=" + gID + "&activityID=" + aID);
If you don't need to add to the string:
$('#activities').load('#Url.Action("_Activities", "Home", new { goalID = Model.goalID},null)');

I really need the path to get this to work, maybe its IE7. Who knows. But this worked for me.
Grab the URL and store it somewhere. I chose to implement the data attribute from HTML5.
<div id="websitePath" data-websitePath='#Request.Url.GetLeftPart(System.UriPartial.Authority)#Request.ApplicationPath'></div>
Then when you need to perform some AJAX or otherwise use a URL in javascript you simply refer to the stored value. Also, there are differences in the versions of IIS (not cool if your devbox is IIS5 and your server is IIS7). #Request.ApplicationPath may or may not come back with a '/' appended to the end. So, as a workaround I also trim the last character if it is /. Then include / as part of the url.
var urlprefix = $('#websitePath').data('websitepath');
urlprefix = urlprefix.replace(/\/$/, "");
var url = urlprefix + '/service/service?param1=' + param;

While the accepted answer is correct I would like to add a suggestion (i.e. how I do it).
I am using MVC, and any ajax request goes to a controller. My controllers have services so if a service call is required the controller will take of that.
So what's my point? So if ajax always communicates with a controller, then i would like to let the MVC routing resolve the path for me. So what I write in Javascript for url is something like this:
url: 'controller/action'
This way there is no need for the root path etc...
Also, you can put this in a separate Javascript file and it will also work whereas #Url.Content will need to be called on the view.
