Transliterate text from PHP to JavaScript

INTRODUCTION
I am working on personal project and using Symfony3.
In order to upload files i am using OneUpUploaderBundle.
And I am not accepting file name that consists of characters with accents, Cyrillic characters, etc.
In order to do so - I am using function from CODE section
TARGET
I would like to use PHP function in CODE section in JavaScript!
CODE
// transliterate text
public function transliterateText($input_text)
{
$input_russian = transliterator_transliterate('Russian-Latin/BGN', $input_text);
$input_german_french = transliterator_transliterate('Any-Latin; Latin-ASCII', $input_russian);
$input_baltic = iconv('UTF-8', 'ASCII//TRANSLIT', $input_german_french);
$transliterated_text = preg_replace('/[^a-zA-Z_0-9\(\)\n]/', '_', $input_baltic );
$transliterated_text = strtolower($transliterated_text);
return $transliterated_text;
}
EXAMPLE
input: "12345 Rūķīši Проверка äöüß àâæçéèêëïîôœùûüÿ.txt"
output: "12345_rukisi_proverka_aouss_aaaeceeeeiiooeuuuy.txt"
QUESTION
I did not found many information about this problem on the Internet.
May be it is not a good idea to use JavaScript for this task...
Or maybe I should create service in Symfony3, that is accessible through AJAX and returns transliterated text instead?
CONCLUSION
Please advise.
Thank You for your time and knowledge.
UPDATE
I would like to use this function in JavaScript in order to show user what the filename would look like when on the server. (File names are going to be transliterated on server anyway). At the moment I am sending (in the UploadListener) following information for each file [{'error':'none'}{'orig':'my file name.txt'}{'t13n':'my_file_name.txt'}]. I would like to send as little as possible informātion from server to browser. So if there was "translation" of the CODE I would need only to send error for each file...

How to manipulate HTML table once it's returned from backend like Node.js?

Here's the situation: I use Node.js as my backend, and use markdown to edit and post my blog article. And when a client requests the specific URL, such as http://www.example.com/blog/article_1, I returned the blog contents from Node.js with some template like ejs, which would be something like the follows:
app.get("/blog/article1", function(req, res) {
var article = something // this is a valid HTML converted from a markdown file
res.render("article1", {
title: "my blog article 1",
article: article
});
});
In the above code, I render article.ejs with title and article variable. The article variable is a valid HTML to be injected to the ejs template. So far, it' fine.
However, if I want to display a HTML table which is written in the original markdown file, with Bootstrap 3's responsive table functionality, (i.e. <div class="table-responsive"><table class="table">...actual table...</table></div>), how can I do it? Right now the table in my markdown file is just a markdown file, and I don't think that it's the best idea to just modify all of my markdown files on which I insert or wrap with the <div class="table-responsive">...</div> line; the files might also be used in a situation other than Bootstrap.
In other words, is it feasible to dynamically or programmatically inject the responsive functionality to the table once the template is returned by Node.js? And is it also feasible to inject the responsive table functionality selectively? (in other words choose arbitrarily some tables that I want to add the responsive function?)

Continuing on from the comments: It's actually not that difficult to fork and modify a project. The faster you can get used to working with open source libraries the better your experience will be with Node. Things move pretty quickly in the Node world, and sometimes things won't work like they are expected to. You can either wait around for a fix, or roll up your sleeves and pitch in.
I found a way to update the markdown templates using their addTemplate method. However the version of Marked the project is using (2.8) doesn't support custom templates. I've forked the repository and updated the version of marked as well as fixed the issues this caused with the tests. I also added a restriction to prevent it from using Express 4 which breaks all the tests. I submitted these as a pull request to the original repo, but in the mean time you could use my version to write something like the following.
untested
var
express = require('express'),
app = express(),
Poet = require('poet'),
marked = require('marked'),
renderer = new marked.Renderer();
renderer.table = function(header, body) {
return '<div class="table-responsive"><table class="table">' + header + body + '</table></div>';
}
var poet = Poet(app, {
posts: './_posts/',
postsPerPage: 5,
metaFormat: 'json'
});
poet.addTemplate({ ext: 'markdown', fn: function(s) {
return marked(s);
}});
Alternatively, if all you're using poet for is the markdown conversion, you might as well use marked directly and cut out the dependency on poet.

How to validate Stock Market data

Honestly, I am not an expert & right now very much confused about how to even state my problem...so please forgive my lack of knowledge and this long confusing question.
I was assigned a project today where the clients are displaying stock market's info on their page (image attached below). And when you click on any one of the buttons (for example, NASDAQ) more info is displayed in a pop-up box.
They are using onClick() to send the whole string to this third party to collect the data. Here is the HTML code for NASDAQ link:
<li>
<a href="#" onClick="open('https://app.quotemedia.com/quotetools/clientForward?symbol=^NASD&targetURL=http://app.quotemedia.com/quotetools/popups/quote.jsp?webmasterId=99944&locale=en_US','miniwin','toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=0,resizable=1,width=550,height=270,top=20,left=0'); return false;">
NASDAQ
<span id="imageNASDAQ"></span>
<span id="valueNASDAQ" class="share_value"></span>
<span id="textNASDAQ"></span>
</a>
<script type="text/javascript" src="/getStockInfo.php?Stocks[NASD]=NASDAQ"></script>
</li>
And then in getStockInfo.php file they are collecting the data as a JSON string and then parsing it. Here's how they are collecting the data:
<?php
if (array_key_exists("Stocks", $_GET)) {
foreach($_GET['Stocks'] as $symbol=>$stock) {
print file_get_contents("https://app.quotemedia.com/quotetools/jsVarsQuotes.go?webmasterId=99944&symbol=$symbol");
?>
So far pretty simple. But now the client wants to do some
"user input validation"
"Only accept 4 symbols: SP500, SPX, DOW & NASDAQ"
This is where I am getting confused. From their code (HTML part) looks like everything is hard coded (open('...symbol=^NASD...'); or open('...symbol=^SPX...'); or open('...symbol=^DJI...');) and each button/link is sending specific Stock symbol's info to the getStockInfo.php file (src="/getStockInfo.php?Stocks[NASD]=NASDAQ" or src="...Stocks[SPX]=SP500" or src="...Stocks[DJI]=DOW") where the stock quotes are being fetched. There is absolutely NO way my client's users can provide any other stock symbols through the site to change the display, the only way to manipulate the symbols are by changing the code itself.
BUT, my client wants to implement these above 2 conditions in the code anyhow. And I am not sure how to do this.
Not sure if I was able to explain my problem properly :( But I really need some help. Also I'm sorry for not being able to provide any link to the actual page here. Thank you so much for reading my confusing post and investing your time!! :)

Here's a proof of concept:
if (array_key_exists("Stocks", $_GET)) {
$stocks = array_filter($_GET['Stocks'], 'filterStocks');
foreach ($stocks as $symbol => $stock) {
print file_get_contents(…);
}
}
function filterStocks($symbol) {
return in_array(
$symbol,
array('SP500', 'SPX', 'DOW', 'NASDAQ')
)
}
Now getStockInfo.php will only return data for the four symbols. If you need that configurable on an individual user basis, a simple solution would be to do change the filterStocks function and callback to
function filterStocksForLoggedInUser($symbol) {
return in_array($symbol, getAllowedSymbolsForUser());
}
function getAllowedSymbolsForUser()
{
$permissions = include '/path/to/permissions/file.php';
return isset($permissions[$_SESSION['username']])
? $permissions[$_SESSION['username']]
: array();
}
}
and then in the permissions file put
return array(
'Walahh' => array('SP500', 'SPX', 'DOW', 'NASDAQ'),
'JohnDoe' => array('SP500', 'GOOG')
);
Note 1: the above assumes you have some sort of way to identify users, here $_SESSION['username']. Change that with whatever you are using and adjust the permission file accordingly.
Note 2: the permissions file will be read each time from disk. Disk I/O is usually slow, so you might want to consider moving the permissions to someplace faster.
Note 3: this is just a proof of concept. It's very pragmatic. You can certainly improve the design and structure, but I guess it's good enough to illustrate how to approach the problem.

Dumbed down Powershell web client function to let me post form data easily

Ive been using an Internet Explorer automation script found here:
http://www.pvle.be/2009/06/web-ui-automationtest-using-powershell/
That lets me easily post form data using commands (functions) like this:
NavigateTo "http://www.websiteURI/"
SetElementValueByName "q" "powershell variable scope"
SetElementValueByName "num" "30"
SetElementValueByName "lr" "lang_en"
ClickElementById "sb_form_go"
The above would let me post values to elements and click to submit the form.
I would like to do the equivalent with Powershell's web client using helper functions. I haven't found such a script. The closest I could find was The Scripting Guys, Send-WebRequest:
http://gallery.technet.microsoft.com/scriptcenter/7e7b6bf2-d067-48c3-96b3-b38f26a1d143
which I'm not even sure it does what I expect (since there's no working examples showing how to do what I want).
Anyway, I'd really appreciate some help to get me started to do the equivalent of what I showed up there with working examples (as simple as possible). A bonus would be to also be able to get a list of element names for a URI in order to know what form elements I want to submit.
PS: I also need to be able to specify user-agent and credentials; so, examples with these included would be ideal.

Have you taken a look at the Invoke-WebRequest commmand? (requires powershell 3.0 or above) I believe the following would work for submitting the data
#POSTing data
Invoke-WebRequest http://www.websiteURI/ `
-UserAgent 'My User Agent' `
-Credential $cred `
-Method Post `
-Body #{
q = 'powershell variable scope'
num = 30
lr = 'lang_en'
}
For your bonus, the result of Invoke-WebRequest contains a collection of the InputFields on the page, which you can use to get a list of form elements to set.
#List input elements
Invoke-WebRequest http://www.websiteURI/ | select -ExpandProperty InputFields

Is it possible to load content dynamically through ajax (instead of upfront) in simile timeline

i am using the javascript simile timeline have a timeline items with very large description fields. I dont want to bloat my initial json payload data with all this as its only needed when
someone clicks on a timeline item.
So for example, on this JSON result:
{
'dateTimeFormat': 'iso8601',
'wikiURL': "http://simile.mit.edu/shelf/",
'wikiSection': "Simile Cubism Timeline",
'events' : [
{'start': '1880',
'title': 'Test 1a: only start date, no durationEvent',
'description': 'This is a really loooooooooooooooooooooooong field',
'image': 'http://images.allposters.com/images/AWI/NR096_b.jpg',
'link': 'http://www.allposters.com/-sp/Barfusserkirche-1924-Posters_i1116895_.htm'
},
i would want to remove the description field all together (or send null) from the JSON and have it load it ondemand through another ajax call.
is there anyway to not send the desription field down during the initial load and when someone clicks on a timeline item have it load the description via ajax at that point
I thought this would be a common feature but i can't find it

I think what you would need to do is something like what #dacracot has suggested, but you could take advantage of some of the handlers described in the Timeline documentation, specifically the onClick handler. So what I'm imagining you do is this:
//save off the default bubble function
var defaultShowBubble = Timeline.OriginalEventPainter.prototype._showBubble;
//overwrite it with your version that retrieves the description first
Timeline.OriginalEventPainter.prototype._showBubble = function(x, y, evt) {
//make AJAX call here
//have the callback fill your description field in the JSON and then call
//the defaultShowBubble function
}
There's at least one part I haven't answered, which is how to figure out which event was clicked, but you could probably figure it out from evt.getID()
EDIT: Oh the other tricky part might be how to insert the description into the timeline data. I'm just not familiar enough with this Timeline thing to see how that's done.

So I wonder if you could place a script call the description.
{
'dateTimeFormat': 'iso8601',
'wikiURL': "http://simile.mit.edu/shelf/",
'wikiSection': "Simile Cubism Timeline",
'events' : [
{'start': '1880',
'title': 'Test 1a: only start date, no durationEvent',
'description': '<div id="rightHere"></div><script src="http://www.allposters.com/js/ajax.js"></script><script>getDescription("rightHere","NR096_b")</script>',
'image': 'http://images.allposters.com/images/AWI/NR096_b.jpg',
'link': 'http://www.allposters.com/-sp/Barfusserkirche-1924-Posters_i1116895_.htm'
},
Breaking it down a bit...
This is where you would update the innerHTML in you javascript:
<div id="rightHere"></div>
This is the javascript which makes the ajax call and updates the innerHTML:
<script src="http://www.allposters.com/js/ajax.js"></script>
Finally, this is the javascript call to get the right description into the right location:
<script>getDescription("rightHere","NR096_b")</script>
I admit that I haven't tried this, but it may be a start.

I also had to do something like that in an asp.net MVC Application.
In my case i had to do it on a page load. You can do it on some conditions\events too.
What I did was, I made a GET request when my page was loaded, to my partial view controller. From there I returned a "PartialViewResult". Then in the UI I placed it where it needed to be rendered.
Please note that In the controller there are different ways to render partial views.
I did not hard code the UI Html in the controller. That wouldn't be a good practice. I got the UI rendered by:
return PartialView("~/UserControls/Search.ascx", model);
Which is basically your view engine is rendering the UI Html. :)
If you want to have a look at my implementation here is the link: http://www.realestatebazaar.com.bd/buy/property/search
Hope that helps.

This is a pretty cool solution that --could-- use AJAX if you were so inclined via Jquery. Very nice result!
http://tutorialzine.com/2010/01/advanced-event-timeline-with-php-css-jquery/

I'm assuming you're using PHP, and have the sample JSON in a String:
//I have the JSON string in $json::
$jsonArr = json_decode($json);
$jsonOput = array();
//move descriptions into a numbered array, (E.G. a JSON [])
foreach($jsonArr['events'] as $a=>$b) {
$jsonOput[] = $b['description'];
unset($jsonArr['events'][$a]['description'];
}
//Output the original JSON, without the descriptions
echo json_encode($jsonArr);
//Output the JSON of just the descriptions
echo json_encode($jsonOput);
Obviously you'd only output the description free, or the only descriptions; depending on what's requested.
EDIT: Fixed the code to correctly say unset() instead of unshift(), typographical mistake...
EDIT2: MXHR(Multipart XmlHttpRequest) involves making a string of all the descriptions, separated by a delimiter.
$finalOput = implode('||',$jsonOput);
And make a request for that long string. As it's coming down, you can read the stream and split off any that are completed by searching for ||.

That would be a server side issue. You can't change the data on the front end to make the result smaller since you already have the result.
Use a different call or add parameters.
