Is it possible to reuse HTML tags across multiple files, headers and footers for example? Placing them in separate files adds an extra HTTP request, that I'd like to avoid.
I don't want to replicate minor changes in headers and footers across every html file every time a change request comes along.
HTML is not a programming language - it's a markup language. You don't do object-oriented HTML because it isn't object based. This is the whole purpose of a server-side language, so you can make include files and use them in your server-side application.
If you have Apache however, you can use server-side includes which don't require a programming language such as PHP, but it's less flexible:
<!--#include virtual="/footer.html" -->
First, HTML isn't even a programming language, so it's impossible to have "Object-oriented" HTML.

If this is the reason for your "without server side code" requirement, then you are mistaken - the client does not fetch the templates that make up a page separately; the server side code will return a single HTML page to the client.
If, on the other hand, you don't have the option to run any server-side code at all and have to make do with static HTML pages, then there's only two options I can think of: iframes (which do result in separate HTTP requests, of course), or some sort of tool that basically runs the equivalent of server-side code to embed your reused templates everywhere and spits out the result to be uploaded to the server. You can have this effect by running a PHP/Apache-with-SSI/JSP/Whatever server on your development machine and using wget to make a static snapshot of the pages.
What I want to do is this. The files can be scattered during development. But I when I'm ready to release, a toolkit should compile the included files into a single html file.
You can use a template language/engine, such as jinja2.
You can layout files in a certain hierarchy, and have templates inherit from other templates, and include other templates, and define reusable macros (closest thing to what you referred to as "reusable tags").

I know this is late, but CodeKit's .kit language lets you do exactly what you were saying.

I think the language you've chosen in your question (object oriented HTML) is actually masking the real issue you have here...

This sounds like a job for a preprocessor, I don't believe it has anything to do with your webserver or server side technology, as this is a step which would happen before deployment.
There's a number of text pre-processors available eg M4 - hell you could even use the C compiler pre-processor if you wanted. A quick google reveals that there are specialised pre-processors for HTML as well....
Automatic file inclusion, automatic escaping, and whatnot that can be done with automatically inserted headers and footers, chosen based on path patterns.
Seems to fit the bill?
Sure . But these would have to be separate ajax calls form the client . There are lot of javascript mvc frameworks like that do that .
If you want to have include files during development, then compile them into free-standing HTML files, you could do that by spidering your development server with wget: whatever server-side technology you use will combine the files and return the HTML, which wget will saves as one file.
As everithing is object over the technology but not directly, indirectly interacting with the object that are created at different level as per security implementation.
You can do this.
I just released a mature framework called Hypertag that is, in fact, Object Oriented HTML. It is entirely client-side, in continuous development, and allows for very interesting, yet HTML-compatible, advanced solutions for logic and layout.

I have a webpage written in html which has a button on it. When this button is clicked, it should hypothetically call on a function located in a separate file which is written in Go.
However, after trying to implement this, I am starting to doubt whether this is possible at all. I've read some documentation about this, but am confused as to how I would import this function in html as the normal <script type = "text/javascript" src="function.js"></script> isn't quite working from what I assume is due to the type error. From what I have been able to find text/javascript is a unique type and there is no text/go equivalent. Does anyone have any references or links which would help direct me in the right direction as to how I could go about calling the method I've written in my .go file when a button is clicked on my html page?
Here is the program structure below:
Program
-- home.html
-- settings.go
What you're describing definitely isn't possible, for a few reasons.
Go is a compiled language. Unlike JS, Go programs are binaries. So their source wouldn't be needed, a binary would. This concept is implemented by Web Assembly and you can use go to build web assembly. But again, it is compiled before being distributed.
Javascript is unique in being a primary component of html browser environment and enjoys integration with the browser. No other languages do this: not Go, python, etc.
It's technically possible to turn any language into Javascript, but I'd advise leaving such shenanigans alone for now.
But you can write a program in Go and then interact with it from the browser. Your Javascript would make http requests to a Go program serving http. You'd be responsible for deciding how data was exchanged.
I have some text that is pretty repetitive on a web page. It can change from time to time. If I write it in 10 different places then need to change it, I have to go through the html and change it in every single place.
As an example of what I'm looking for, instead of writing "Stack Overflow is the best website ever" over and over again, is there a way that I could write something like variable:stackoverflow="Stack Overflow is the best website ever" in one place then write "stackoverflow" in the 10 different places I need the text. That way if/when I need to change it I can just change it in the one place, not the 10 different places on the page.
No.
Typically this problem is solved by generating HTML using a programming language, often in combination with a template language.
This can be done either at:
build time, generating static files and uploading them to a server), e.g. using a tool such as assemble
server side (on demand when the page is requested), e.g. using FastCGI and the programming language of your choice
client side (using JavaScript running in the browser … although this isn't considered best practise).
You can't declare such variables in HTML. I guess, it's the best way, to use PHP. PHP is executed by the server and a HTML-Document will be send to the client. JavaScript is executed by the client and some users denie the JavaScript-execution.
In my opinion it's he best way is to use PHP.
For display texts in PHP, you should check out the website PHP.net
Since my experience with HTML is fairly rudimentary (and pretty old), I am not sure if my requirement is realistic.
Lets say that I have quite a few files containing Lua source-code, and all of them have the ".lua" extension and available in a particular subdirectory. What I'd like to do is create a static index.html file, which when loaded in a browser, would show the list of the lua source-code files in a drop-down. Once one of the source-code files is selected, I'd like that the file gets loaded into an "area" on the same page, and is pretty-printed, i.e. with syntax-highlighting in browser. I was wondering if I could use something like the google-code-prettyfy for the syntax-highlighting part ? Also, I am not clear if an external lua sourcecode file can be loaded, and displayed within a certain region of html page as being rendered. If yes, would appreciate elaboration on the how part.
A tool like LDoc can be used to accomplish a lot of what you want, much as Doxygen would be used for a C language source kit.
Both are heavily driven by inclusion of specially formatted comments that carry documentation.
I know Doxygen can fold source code into the generated document set, I don't recall about LDoc. Both are actively under development.
It isn't necessarily a bad idea to use both tools on a project, especially if you have C source code implementing Lua modules. You could use Doxygen to build the overall document tree for your engine and C modules, and LDoc to build documentation of the Lua parts. It should be possible with a little care and configuration of both tools to get them to play well together.
I have two html files, I used 2 different frameworks to create 2 different web application for smart phones and other devices such as tablets.
now I have to use Velocity Macro, and merge this two html files into a single vm, that generates 2 outputs depending on a configuration.
i have been searching for methods to do this and I found this: http://www.roseindia.net/apachevelocity/macro-wrap-html.shtml
My question is do I need to build a Java fie just like in the link and then make a vm file, or can I just make a single vm file without making any java files?
if my question in unclear let me know I try to explain more.
The Java class shown there is just to demonstrate the template, and all the template does is demonstrate how to use the Velocity #macro directive.
IMO putting both HTML files into a single VM template is a bad idea, because it will be large and difficult to understand, modify, and debug. Instead, consider using the #parse or #include directives.
Alternatively, consider a mechanism at a higher level to serve the appropriate pages directly instead of pushing the template decision-making process into the templates themselves--this is arguably the best solution.
Currently I am working on a project for a client that compares the difference between two XML files, generates an XML that lists the differences (i.e. if a part in an inventory was <Added>, <Deleted>, or <Modified>) and displays a report in HTML.
I have three transforms that basically transform large vendor-specific XML files to simple generic XML files (schema defined). These generic XML files are then transformed into one generic XML file that shows the differences and then that is transformed to a report.html for display for the user.
Presently for testing, I invoke a .bat file to run all three transforms (using Saxon8.jar). My question is, is it possible to put these transforms on a server and create a HTML page with a one-click action that will let the user upload the vendor-specific XML files, transform them, and display the generated HTML file to the user?
You haven't specified whether you'll be using php, java or ASP.NET, however, the functionality you're looking for is possible in all three cases. Your backend web app should have the necesssary mechanism to accept the file uploaded by the user, save it in some work folder, run the necessary transformation using your chosen language, Jave, C#, php etc. and then write back the HTML.
Is it possible? Yes.
To do it you'd typically use some server-side technology (php, ruby, java) to perform the transforms.
But browser-side XSLT is possible, too.
Apache Cocoon is a powerful XML processing engine.
If you're just doing this one job, then coding a Java servlet to do it is not too difficult. If you're doing lots of similar things, a framework like Cocoon or Orbeon will save you effort in the long run.
