   • What are the uses of XMLHTTPRequest Object in Ajax ?

     In this article, we will know about the XMLHTTPRequest and how it can be useful for client-server request and properties of XMLHttpRequest.

     XMLHTTPRequest is an object that sends an HTTP request to the server and interacts with the server to open a URL and retrieve data without loading the complete page so only some part of the web page changed. Here, it is a global constructor function XMLHTTPRequest built into the browser exposed in javascript that is available without any package added and is not only to XML documents, nowadays JSON is mostly used to exchange data between browser and server.

     Uses of XMLHTTPRequest object:

     • It is used to make AJAX calls to exchange data from a remote web server. 
     • With the help of this object, users send requests to the server asynchronously and the server sends the data which we requested for Ajax.

   • What's the point of having hidden input in HTML? What are common uses for this?

     Top Answer

     Answered Sep 06, 2011 · 26 votes

     They're used to pass data that will be needed when the form is submitted. One of the more common cases would be a form allowing users to edit some existing entry. You'll need to know which entry they're editing so that you can update the correct row in the database when they submit the form. The user doesn't need to edit (or even know) the ID of the entry though, so a hidden field works well here.

     Other options

     URL parameters: This could also be done by building the parameters into the url that the form is being submitted to:

     <form action="save.php?entry_id=1234">-

     but this means you have to handle building the URL properly and escaping the data yourself, and the length of URLs servers will accept is limited so it may not work for longer data. So generally using hidden form fields is the easier way to go.

     Session variables: When the edit page loads you'd store the entry ID in a session variable, and then retrieve it on the page that saves the changes. That's a lot easier to mess up though; setting up and maintaining sessions may require adding code in several different places, and then their session could expire in between loading and saving, and you have to make sure it works if they have multiple windows or tabs open, and you have to make sure it doesn't do weird things when they hit back/forward. Because of all these potential pitfalls it isn't a great way to solve this problem--passing the id with the data being submitted is a lot more robust.

     Cookies: In many languages/frameworks sessions are tracked using cookies, so they're basically the same solution. The pitfalls are the same as for session variables even when sessions are tracked by other methods though.

     It sends additional information that the user doesn't know or isn't interested in (such as a security token) so that if the form is submitted twice, you can compare the tokens and reject/accept that submission.

     Not using hidden inputs means the server needs to keep track of these values instead. This requires the server to keep state, which could otherwise be embedded into the request (form) itself. This may make the page RESTless (not RESTful), i.e. break the self-containedness of an HTTP request. If you did keep track of hidden values on the server, you would at least need to embed a unique token into each form to deal with several different unique submissions of the same form. The cleanest way to embed such a token is, drumroll, through a hidden input. :)

   • What are the Building Blocks of HTML?

     HTML is the backbone of web content, which consists of fundamental building blocks that define the structure of a webpage. These building blocks include elements like Tags, Attributes, and Elements.

     Features

     • HTML elements define the structure of a web page.
     • Tags provide semantic meaning to content, such as headings, paragraphs, lists, etc.
     • Attributes can be added to tags to provide additional information or functionality.

     Syntax:

     <!DOCTYPE html><html><head> <title>Your Title Here</title></head><body> <!-- Your content goes here --></body></html>-

   • What are the Types of HTML Page extensions

     Top Answer

     Answered Oct 05, 2015 · 8 votes

     Here are as many file extensions related to web pages that I can find which fit the paradigm ".[a-z]html."

     .dhtml - a text file that contains dynamic HTML code, which is used for developing interactive Web pages that can change without being reloaded or opening another link.

     .phtml - a text file that contains PHP code. The PHP code is parsed on the web server in order to dynamically generate HTML code. ".php" is much more commonly used for web files containing PHP code.

     .jhtml - a text file that contains Java code; may include Java functions that are processed on the server before the page is sent to the client's Web browser.

     .mhtml - Web page archive format saved from a .HTML file and encoded with .MIME encoding. Includes resources linked from the Web page, such as images, Flash animations, Java applets, audio files, etc. Can be opened and viewed without being online. Microsoft Word can save and open MHTML Web archives.

     .rhtml - Web page containing Ruby code or scripts. It is processed on a Web server running Ruby on Rails before the page is sent to the Web browser.

     .shtml - Web page written in HTML that contains server side includes. It processed by the Web server before being sent to the users browser. It can reference other files on the server, i.e. "header.shtml" or "_footer.shtml."

     .zhtml - Web page parsed by RabbitWeb, a Web server that integrates .C program code with special HTML tags. The file contains embedded "ZHTML" commands that are used to generate dynamic content for the webpage.

     It should be noted that it is very rarely appropriate to store a file using any of these extensions - ".html" or ".html" are the standards for any text files that are meant to published to the Web. The only exception to this rule might be ".mhtml", which is a format exclusive to Microsoft. However, IMO, ".mhtml" archives are rarely the best solution for saving copies of web pages and their content; it is much better to convert the page to a .PDF file or some other type of file that doesn't store linked resources locally as individual files (which can litter a user's local directory).
