set file attribute filesystemobject javascript

I have created a file as part of a script on a network drive and i am trying to make it hidden so that if the script is run again it should be able to see the file and act on the information contained within it but i am having trouble doing this. what i have so far is:
function doesRegisterExist(oFs, Date, newFolder) {
dbEcho("doesRegisterExist() triggered");
sExpectedRegisterFile = newFolder+"\\Register.txt"
if(oFs.FileExists(sExpectedRegisterFile)==false){
newFile = oFs.OpenTextFile(sExpectedRegisterFile,8,true)
newFile.close()
newReg = oFs.GetFile(sExpectedRegisterFile)
dbEcho(newReg.Attributes)
newReg.Attributes = newReg.Attributes+2
}
}
Windows Script Host does not actually produce an error here and the script runs throgh to competion. the only guides i have found online i have been attempting to translate from VBscript with limited success.
variables passed to this function are roughly declared as such
var oFs = new ActiveXObject("Scripting.FileSystemObject")
var Date = "29-12-2017"
var newFolder = "\\\\File-Server\\path\\to\\folder"
I know ActiveX is a dirty word to a lot of people and i should be shot for even thinking about using it but it really is a perfect fit for what i am trying to do.
Please help.

sExpectedRegisterFolder resolves to \\\\File-Server\\path\\to\\folder\\Register which is a folder and not a file.
I get an Error: file not found when I wrap the code into a try/catch block.
I tested the code on a text file as well, and there it works.
So you're either using the wrong method if you want to set the folder to hidden.
Or you forgot to include the path to the text if you want to change a file to hidden.
( Edit: Or if Register is the name of the file, add the filetype .txt ? )
If you change GetFile to GetFolder as described in https://msdn.microsoft.com/en-us/library/6tkce7xa(v=vs.84).aspx
the folder will get hidden correctly.

read value from txt file in javascript

I have a simple html file in which there's javascript code referring to google charts.
The code I use is this (I'll show the important part):
function drawChart(){
var data = google.visualization
.arrayToDataTable([ ['Label', 'Value'],['Temp', 22.75],]);
// etc...
}
I use a bash command (sed) to replace that 22.75 value with a new one from the last line of a .txt file. However, this throws some errors which I haven't been able to neither correct nor ever identify.
So is there any javascript code that takes that file, extracts the last value and simply displays it on the right place of the code?
UPDATE:
Sorry for the lack of info in this question, I really appreciate all the people that took the time on reading my question. I'll try to fill with more information in the next minutes.
I am able to extract the last line of the .txt file, extract the value on the right part of the '-' symbol and store it in a variable. Then that value is taken to update the html file with a sed command. The error comes when the value is updated but with no value. I guess that happends due to a failed record of temperature in the txt file, then the extracted value is a null. Finally is the html fiel with javascrit code happens to be like this:
(...)['Temp', ],]);
Then the updater can't update the value since due to the way that sed command is written I guess there's no way that it can detect a no-number-value in there. So the html remains without a value all the time.
TXT File structure:
(...)
20:25:03-23.312
20:26:02-23.312
20:27:03-23.375
20:28:03-23.375
20:29:02-23.375
20:30:02-23.312
Bash script:
# (...code...)
lastRecord=`cat /home/pi/scripts/temp_control/logs/"$today".log | awk 'END{print}'`
function rightNow {
lastTemp=`echo $lastRecord | cut -d'-' -f2`
timeOfTemp=`echo $lastRecord | cut -d'-' -f1` # Not used yet
#Command used to update
sed -i "s/['Temp', [0-9]\{1,2\}.[0-9]\{1,3\}]/$lastTemp]/" /var/www/rightnow.html
}
rightNow

You cud get your file just like any other ajax request.
Using javascript
var request = new XMLHttpRequest();
request.open('GET', 'public_path_to_file.txt', false);
request.send();
var textFileContent = request.responseText
Using jQuery
var textFileContent;
$.get('public_path_to_file.txt', function(data) {
textFileContent = data;
});
Whats left is to get the right part from textFileContent. Dependent of the structure of the file we can do this in different ways. Without an example file you are on your own but here is some examples.
If you need the last line
var lines = textFileContent.split("\n");
var lastLine = lines[lines.length - 1];
If you need to use regex
var regex = //* some regex to get your content*//gm;
var result = regex.exec(textFileContent);
// result should now the content who matches your regex

First I'll assume that you ultimately want to read a local file with your browser and your current workflow is something like a local 'bash-script' that
first updates/modifies an inline piece of javascript (inside a locally stored html
file) with the last occurring value retrieved from a local txt-file (using sed)
opens the (just modified html-) file (via commandline) inside a common browser.
Then I assume the sed-route once worked but now doesn't work anymore (probably because the html file has changed?) and now you'd like the inline javascript (in the html file) to fetch that value from the textfile itself and subsequently use it (thus without the need for the 'bash-script'/sed solution.
Thus, the answer (based on above assumptions) to your final question: 'is there any javascript code that takes that file, extracts the last value and simply displays it on the right place of the code?', depends on your final requirement:
are you ok with a file-input where you select the text-file every time you view the html-file?
If your answer is YES, then, (depending on the browser you use) you can read a local file (and work your magic on it's contents).
In modern browsers, using the File API (which was added to the DOM in HTML5) it's now possible for web content to ask the user to select local files, then read the contents of those files.
For example, using FireFox's 'FileReader' you could do:
html:
<input type="file" id="fileinput" multiple />
javascript:
function readAllFiles(evt){
var files = evt.target.files, i = 0, r, f;
if(files){
for(; f = files[i++]; ){
r = new FileReader();
r.onload = (function(f){
return function(e){
alert(e.target.result);
};
})(f);
r.readAsText(f);
}
} else {
alert("Error loading files");
}
}
document.getElementById('fileinput')
.addEventListener('change', readAllFiles, false);
Note that for accessing local files in Chrome you must start Chrome with this switch: chrome --disable-web-security
However,
if the answer is NO (so you want to specify the file, and more importantly it's path, inside the 'code', so you don't have to select the text-file every time your local app runs) then you (usually) can't (because you can't get/set the path, thank the great maker)...
Unless you choose a specific older/unpatched browser (specifically for this task) where you know of a (hack) way to do this anyway (like the IE xml vulnerability or the XMLHTTP vulnerability or etc... you get the picture..).
Some alternative solutions (that don't require you to select the correct textfile over and over again)
Setup a fullblown web (LAMP) server (to use the XMLHttpRequest way as used in aross answer, but this might feel like shooting at a mosquito with a cannon..)
Explore different script languages (but effectively still do the same as your now broken sed-solution)
Combine 1 and 2, choosing from php (the latest version has a small webserver included, you might start/stop it when needed (even in the bash-script workflow) OR using node.js (which is 'javascript' and where you can program/control a small task-specific server in just a couple of lines).
Hope this helps!
Update:
Based on your updated question, comments and request for recommendation, I'd like to suggest to use PHP to dynamically fetch the value from your log txt file and have it generate your html code with inline javascript on the fly (every time you visit the page).
The browser will never see the php code, only what php inserted to your page (in this example the last found value or 0).
You'd rename the rightnow.html file to rightnow.php and modify it (something like) this:
<!DOCTYPE html>
<html><head>
<!-- your header code -->
<script type="text/javascript">
//parts of your javascript
<?php // start php script
$logFile= '/pathToYour/logFile.log'; // <-Modify
if( $fp= #fopen($logFile, "r") ){ // if logfile succesfully opened,
fseek($fp, -30, SEEK_END); // set pointer 30 chars from EOF
$val= array_pop(explode("-", rtrim(fread($fp, 30)))); //get last value
fclose($fp); // close file
}
?> // end php script
function drawChart(){
var data=google.visualization
.arrayToDataTable([ ['Label', 'Value'],
['Temp', <?php echo $val? $val : "0"; ?>],
]); // ^php above inserts value or 0
// etc...
}
//parts of your javascript
</script>
</head><body>
<!-- your body code -->
</body></html>
Note that fopen in combination with setting the filepointer via fseek and sequentially fread-ing from the pointer to EOF does not load the complete logfile (60min * 24hour=1440 lines of 16 bytes=22.5kB at the end of the day) into memory (good for this purpose), but only the last 30 chars (as in this example).
The variable to your logfile and path must still be modified to your situation (I don't know the format of your $today variable).
Depending on your further needs you might want to perform some extra checks/logic on the array of values that explode returns (instead of popping the last value). Or what about modifying the html a little so you could also include the last temperature's time reading, etc. (But this tested piece of code should get you started and explains the procedure of going the php way).
Update:
Since you have chosen to place the last known value of your logfile as in textfile placed inside your public www-root (with a bash script I assume, every minute of the day?), you can now indeed go the 'ajax' way, as answered by aross!
However I want to hint that the code/solutions in all current answers here could be mixed (since you now also have ajax working): instead of ajax-ing (loading) a txt file, you could have php fetch and send this value to the browser on-the-fly/on-demand!
So, instead of requesting http://url_to_my_rpi/file_to_download.txt, you could request http://url_to_my_rpi/read_last_temperature.PHP which should fetch the last known value out of the log-file (set proper security/access) and send it to the browser (set proper headers), just like your text-file did. You wouldn't have to change anything in the html/javascript except the url you request.
The advantage would be (depending on how your current bash-scripts works) that your PI now only does this 'work' (of getting the last value of your logfile) when you are viewing your monitor-page. And that you are not writing that file in your www-root every minute of every day (as I suspect).

The solution achieved, finally, was like this:
I did it with a jQuery statement and reusing the javascript code of Google Charts.
First I added javascript and jQuery tags in the html file:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
Then I merged jquery code and javascript code that I had in one script:
<script type='text/javascript'>
// Needed this var so that I could use it in other places of the code
var t;
jQuery.get('http://url_to_my_rpi/file_to_download.txt',function(data){
console.log(data)
t=data;
},'text');
google.load('visualization', '1', {packages:['gauge']});
google.setOnLoadCallback(drawChart);
function drawChart() {
t=eval(t);
var data = google.visualization.arrayToDataTable([
['Label', 'Value'],
['Temp', t],]);
// (... more javascript with Google Charts options, display parameters..)
</script>
Finally, and even if it's not listed as the main question, be sure to enable *mod_headers* on your apache and add Header set to apache2.conf file (In my case: /etc/apache2/apache2.conf)
1) Enable the module:
a2enmod headers
2) Add the line on your configuration file
Header set Access-Control-Allow-Origin "*"
3) Restart apache 2
4) In case the 3 steps above didn't work, follow the instrcutions by entering in this website or reinstall apache2.

Values for global Javascript variable is wrong at the momemt to get it

I am ready with a port from a php mvc application to asp.net mvc (using a lot of javascript and google maps). The application works quite well on my development machine (Win 7 + IIS 7). But the problems start on production server. for some reason i have a javascript file wich is not working well when i am using it from my production server.
i.e. I have my view where i load all the data from db and and after that I put this on an global variable array called global_sites_am. Each row in the array contains attributes like latitud ,longitud and name.... After that this array is readed from the js file called maps.js.
var position = new google.maps.LatLng(global_sites_am[i].latitud,global_sites_am[i].longitud);
addMarker(position,global_sites_am[i].name,i);
For some reason this piece of code work fine on my development machine but it doesn't when i have installed the app on production server.
I.E. On Development machine : global_sites_am[0].latitud = 45,6789566 and global_sites_am[i].longitud=72,69452015
But on Production machine : global_sites_am[0].latitud = 45 and global_sites_am[i].longitud=72
What i am doing wrong?
Update: Here is How I load the value from the db to the javascript file:
global_sites_am[count]=new Object();
global_sites_am[count].name='<%=site.Name%>';
global_sites_am[count].latitud=<%=site.Latitud%>;
global_sites_am[count].longitud=<%=site.Longitud%>;
This is one of my properties:
[EdmScalarPropertyAttribute(EntityKeyProperty=false, IsNullable=false)]
[DataMemberAttribute()]
public global::System.Double Latitud
{
get
{
return _Latitud;
}
set
{
OnLatitudChanging(value);
ReportPropertyChanging("Latitud");
_Latitud = StructuralObject.SetValidValue(value);
ReportPropertyChanged("Latitud");
OnLatitudChanged();
}
}
Some debug info from Chrome: http://oi49.tinypic.com/2j4q7p4.jpg. In the image you will see that the values at the moment to load in the page are correct, but at the moment to read them are wrong.

Finally the problem was solved using the next line on the web.config:
globalization uiCulture="en-US" culture="en-US"

Is there a way to AutoFormat (Javascript) code in TestComplete?

So similar to ALt-Shift-F in Netbeans, is there a to do this right in the ide in TestComplete? Not sure if this is possible or if anyone can think of a workaround to autoFormat without leaving the TestComplete window.
I'm trying to get the below solution to work with http://jsbeautifier.org/ for javascript / Jscript code in TestComplete.
Thanks

Great question!
There is no built-in function for that. So, we should not expect any solution to be 100% convenient - it is just not a simple task to modify the current script editor contents (if at all possible). So, whatever you do, it will still be some kind of compromise.
In general, the task is three-fold:
Get the current unit code.
Format the code.
Put the code back to the unit.
According to my understanding, items 1 and 3 can be accomplished only by creating a TestComplete plug-in - accessing editors for project nodes is not an easy thing.
UPDATE: silly me! There is a way to access the script editor code - I've updated the below part.
What will help us avoid switching to a different app, are the Script Extensions:
We create a custom Checkpoint in the form of a Script Extension, and install it to TestComplete. As a result, we get a button on the toolbar that we can click to invoke our code.
In the design time action, we call some code that reads the editor contents, then uses external code formatting functionality, and replaces the editor contents with the formatted code.
It would extremely interesting to see the implementations other TestComplete users can suggest! As a start, I am posting a solution that includes using an external web site to format VBScript code (http://www.vbindent.com/). I know that the starter of the post is probably using JScript, but I have not found a JScript formatter yet.
My solution is a simple Script Extension. I can't post a file here, so I will post the code of the two Script Extension files:
Description file:
<!-- Description.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<ScriptExtensionGroup>
<Category Name="Checkpoints">
<ScriptExtension Name="VBScript Code Indent" Author="SmartBear Software" Version="0.1" HomePage="smartbear.com">
<Script Name="VBIndent.js">
<DesignTimeAction Name="Indent Current VBScript Unit" Routine="DesignTimeExecute"/>
</Script>
<Description>
Indents VBScript code in the currently active unit.
</Description>
</ScriptExtension>
</Category>
</ScriptExtensionGroup>
Code file:
// VBIndent.js
function DesignTimeExecute()
{
if (CodeEditor.IsEditorActive)
{
var newCode = IndentVBSCode_Through_VBIndent(CodeEditor.Text);
if (null == newCode)
return;
CodeEditor.Text = newCode;
}
}
function IndentVBSCode_Through_VBIndent(codeToIndent)
{
var URL_VBIndent = "http://www.vbindent.com/?indent";
var httpObj = Sys.OleObject("MSXML2.XMLHTTP");
httpObj.open("POST", URL_VBIndent, false);
httpObj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
httpObj.send("thecode=" + escape(codeToIndent));
var responseText = httpObj.responseText;
// Extract the indented code from the response
var rx = /<textarea name=\"thecode\".*?>((.*\n)*?)<\/textarea>/;
matches = rx.exec(responseText);
if (null == matches)
{
return null;
}
codeIndented = matches[1];
return codeIndented;
}
After you create these files, and put them to something like "\Bin\Extensions\ScriptExtensions\VBIndent", and click "File | Install Script Extensions | Reload", you will see a new "Indent Current VBScript Unit" item in the custom checkpoints drop-down button on the Tools toolbar. Clicking the element will format the VBScript code in the currently active editor.
So, this is to give a clear idea of what a solution can look like. Better suggestions are welcome! Share your thoughts!

how do I dump an html page as XML with watir & JavaScript?

I have been trying to create a simple script in FireWatir that will convert the entire current document DOM's (including javascript generated code) to XML representation .
following leads on the web I've came up with this script
require 'rubygems'
require 'firewatir'
browser = Watir::Browser.new
browser.goto('http://www.google.com/')
browser.text_field(:id, 'lst-ib').set('hello')
browser.button(:name, 'btnG').click
puts browser.execute_script("new XMLSerializer().serializeToString(document)")
however, running it in Firefox 3.6 , resulted in this error :
c:/Ruby192/lib/ruby/gems/1.9.1/gems/firewatir-1.9.2/lib/firewatir/jssh_socket.rb
:19:in js_eval': XMLSerializer is not defined (JsshSocket::JSReferenceError)
from c:/Ruby192/lib/ruby/gems/1.9.1/gems/firewatir-1.9.2/lib/firewatir/firefox.rb:136:inexecute_script' from test.rb:9:in `'
if I enter this line:
javascript:window.open('aout:blank').document.write('<pre>' + unescape((new XMLSerializer()).serializeToString(document).replace(/</g, '<')) + '</pre>')
into FF location box, I get a page with the desired XML. so XMLSerializer has to be defined somewhere, its just seems out of reach for my JS code.
how can I get this to work?

Not sure what you mean by "location box", but if that is address bar (the one that says http://stackoverflow.com/... at this page), then try this:
browser.goto "javascript:window.open('aout:blank').document.write('<pre>' + unescape((new XMLSerializer()).serializeToString(document).replace(/</g, '<')) + '</pre>')"

A t the core of it, I suspect this might be an FF thing to do with boundaries of the 'sandbox' that javascript is running in. The browser itself may know about the serializer, but not choose to give javascript any access to it.
However, there may be more than one way to skin the cat. If your second bit of code provides you with a page that is rendered as text in XML syntax, why not do that first, and then just use the resulting page via
puts browser.text
