I am developing an web page (html5) for my graduation project. In the web page the user would provide "body type" and based on the input various garments's images would be pulled from database and displayed on the page.
I am not a technical student so failing in my database connection efforts.
I have index.html page, a .mdb db (ms access 2007) and using js to connect to the .mdb. I also installed the "Microsoft Access Database Engine 2010 Redistributable". Then too failing.
Kindly mention what I am missing.
HTML pages are mostly accessed via a Server (IIS, Apache,..) and the data work is done by the server, on the server (AKA ServerSide programming)
So first consider if your project is intended to be accessed this way or only locally / standalone to your very computer.
If you only want a local page, there might be a solution here : http://accessdb.sourceforge.net/
But I bet it only works on IE through ActiveX
Read this : Read and write to an access database using Javascript
Also : why MSaccess ? If you really try to manipulate data locally using JS, try SQLite, there should be many library for JS like this one : https://github.com/lovasoa/sql.js
or why not... the HTML5 webstorage objects, that could be pushed far

I think you have got it all wrong! The short answer is you can not. And that is because your design is wrong. You can not* directly connect form html5 / javascript to a database.
Back to the basics.
You will need server side scripting to read the database content and expose them to the client (javascript) or to embed directly the result to html5 (while server is building the page).
You need to take a look to the following technologies
java / Jsp
c# / aspx
Those will help you to read the db file on the server side. Then as I said you will need to find a way to expose that information to your web page. As a side note, those are not the only server side scripting technologies, but are the one (IMHO) the can read an access file.
So look into that direction you will find a lot of resources to help you.
*The truth is that you can, but this can be considered an 'advance' issue.

I have a local site like no server no nothing just the html, css, javascript files and i need to send data from an app in my phone created with android studio and display it on the site.I read that you can have a webserver and send data with the android/java tcp client to it but i cant find how to do it.So how can i approach this?
This is possible using server-side programming languages.
You can receive data using Api and display it on your web pages after saving it in the database.
To start, I suggest learning Php - Mysql , it's easier to understand and easier to implement
you can send data from your android mobile to the server by using API such as REST and SOAP but you have to any of the server-side scripting languages like node PHP etc.. Please refer the tutorial point to get better ideas

I've developed an application that I would like to use meteor.js for real time updates (I want to enhance but not change my program, for example when a user adds a comments make it update in real-time ) . Problem is meteor.js uses node.js (so javascript as server-side code). I use LAMP stack, Is it possible to get PHP to feed data into meteor.js from mysql.
Meteor is more than just an 'interactive webapplication'-builder or javascript framework. The idea is to have only one programming language (besides HTML/CSS for markup) to do all the work. Basically it creates a 'remote server' (in the clients browser) it can push data to and at the same time it publishes various API's to the users system. The data passed through these API's / connections has a specific structure which has to be adhered at all time.
Meteor is built around NodeJS, which makes it hard (if not impossible) to run it without this backend. Sure you can try to mimic the backend using PHP, but it would be a waste of time. Reading your question you'll be better of using a javascript framework like jQuery or Prototype. Unlike Meteor you will need to do the AJAX calls (POST & CallBack) yourself, but you can actually decide which backend you want to use yourself (including PHP / MySQL).
If you want to do this anyway you need to check the Meteor & NodeJS source code to see what the minimum requirements are to make Meteor run under PHP. The PHP stack has to interpret the commands Meteor sends and receivers, but this won't be an easy task.
You can use comet (or reverse ajax) for realtime updates.
Trying to marry node.js with PHP doesn't sound like a worthwhile path to go down. If someone insisted on using a system like Meteor.js, yet with a PHP back-end, it would make more sense to look at AngularJS which is mainly the client side.
Of course, that is different technology stack. If someone really insisted on the blending, one could consider using server side sockets to interact with PHP Web services; and/or use mongodb and/or mysql-node to interact with the same databases.
I released a meteorite package that interacts with a Wordpress site that has the Wordpress JSON API. A quick fix. For now.
Comes with a backend call that will return the raw data, or a publication that stores the posts using their id's instead of a randomly generated mongoid. And some basic templates to get you started including a Session variable that keeps track of the currently selected post.
I'm working on it a lot more and will eventually have a version that directly makes mysql calls from node so you won't need php or Wordpress; just the ability to access the mysql database (which can be remote, with the appropriate configuration, or on the same machine).
I'm new to Arduino and am trying to connect it to the internet using an EthernetShield. Before I buy the EthernetShield, I want to make sure I will be able to execute the necessary steps with it. Is it possible to use Javascript to write to a text file stored on the server (containing binary data), connect to said server/file address with Arduino, and then use Text Finder (Arduino's) to read the file's binary data and perform the necessary commands? If so, what are the steps (if it diverges from this basic outline)?
It seems fairly straight forward, but through my own research, I am unsure if text files can be written and stored in that fashion, and if the Arduino can read this file type. I'm also aware that the conventional way entails PHP and mySQL, both of which I am fairly unfamiliar with.
Thanks!
Arduino can read text file. I suggest you use XMl or json instead of text file.
I am sharing a link of code for my final year btech project "Controlling devices using internet".
(ofcourse this can be done easily by using arduino+ethernet as server but the problem with this is you need port forward the router in order to access server from outside the local network Port forwarding is little risk as per security aspects.)
I used apache server (for testing I installed in my laptop, later I used hosting sites) and Arduino+Ethernet Shield as client. Arduino sends HTTP request to server for XML file after getting, it parses the XMl and control the devices. I used PHP for creating UI and updating XML file....
I hope this may be useful

I'm working on a Parse web app and have run into some problems using the backbone.js based client side javascript sdk. I noticed the way I have things set up, the client can view all of my source code by simply using the dev tools to view source files and can also run code against the database (within the limits of the ACL's I've set). I've started working on rebuilding the app in cloud code using the Express.js module Parse provides so that all of my code is stored server side, but I was wondering how those using client side frameworks get around this obvious problem.
That's the issue with client-side code. Assume any code you send to the client is hacked, broken, and tampered with.
With JavaScript, your best bet is to use either Cloud Code and send AJAX or streaming data calls to the server, retrieve the data from the server at runtime (not super secure, but would fool some people), or accept that your code is vulnerable.
I typically work with frameworks in the MVC format, so I only expose a limited subset of the actual model via a REST API. I use both a client-side framework and a server-side framework. Any thing sensitive goes on the server.
I am researching how to PunchOut enable a webstore and from what I read, I have to use a server side language. Unfortunatly I am limited to only using Javascript. Can this be done? Does anyone have any best practices or can point me to a reference for enabling a PunchOut ecommerce store by only using Javascript?
According to the cXML Users Guide (http://xml.cxml.org/current/cXMLUsersGuide.pdf) on page 23 it states "PunchOut catalogs are made possible by Web server
applications, written in a programming language such as ASP (Active Server Pages),
JavaScript, or CGI (Common Gateway Interface), that manage buyers’ PunchOut
sessions.". Based on that it sounds possible as they call out JavaScript, but they also call out the fact that it is done by Web server applications. I have not used a strictly JavaScript myself, just ASP and recently .NET.
However, I'm not a JavaScript expert so YMMV. The main thing to keep in mind that most punch-outs (especially from Ariba) will be initiated via an HTTP POST with the cXML document XML as a form value. If you can use JavaScript to process that XML and send back a response without server side work, then you should be good to go.
