I want to add content from my website to the html permanently - javascript

I want to build a website in which users can add information, like craigslist. I want the website user to be able to click a button fill out a form and add another box. For instance, if there is a three by three grid and the user clicks on the add button, I want a form to appear, them to fill it out and one more box to be permanently added to the grid. Of course I could make it happen with Javascript and JQuery but it isn't permanent. Thanks:)

You can Implement this using server side languages like PHP /Node JS, ASP.net, Java, Ruby or you can use Local Storage of the browser (this gives limited storage capacity ). read this for more details. link

If you don't already know PHP, you will need to learn it for this. Also, you will need to make sure that you understand how to validate input because letting users add to your database can be a very dangerous thing to do if you don't understand how things like script injection works.

Advanced Custom Fields - Toggleable Options for the Backend?

I'm building a website using the ACF plugin (Version 5 Pro), and I'm setting up a button on a page template, which by itself isn't the problem. The problem is that depending on the specific content of each individual page using that template, the button can have one of several different appearances. What I'm trying to do is set things up so that I can upload all the buttons into the default value section of the ACF field ahead of time, and then every time I make a new page using that template, simply select the appropriate button from a radio button, a dropdown menu, or something similar on the backend of the page. I plan to be constantly uploading small amounts of content using this template, so not having to manually select the appropriate images on each page would save me a lot of time.
I've googled around and there wasn't a good answer I could find anywhere, so I'm hoping one of you more knowledgeable folks could help me out!
(And before anyone proposes this as a solution, no, the content of each page isn't something I can define just using programming. It's a little more abstract and needs human input. If all else fails I can just make multiple templates and simply select the appropriate one when I go to make a page, but the way I'm trying to do it now would be a lot cleaner).
You can try ACF Flexible Content:
https://www.advancedcustomfields.com/add-ons/flexible-content-field/
Using Flexible Content field, you will be able to create multiple fields (button 1, button 2, etc) including a WYSIWYG editor and build the buttons HTML adding the default value of the field.

However, I think you'll get in trouble making your buttons dynamic with this approach... so I'd suggest it will be better if you keep some parts of the buttons (like URLs) dynamic, using an extra field to enter the URL, anchor, etc.

User-Generated-Content—where to start? Users submits content into divs which adds to the gallery

A user would click a submit button and a function would create a div in a gallery on my site with which they could link to if they wanted to share that content specifically. The content is just embedded and hosted on other sites like youtube so the user would not be actually uploading any content or need an account. It's a free open gallery that anyone could copy a url and paste into an input and submit that content into a div in the gallery.
Any ideas where to start? Would this require php?
Well if you're a super beginner or something the first step would be to make your website just the way you want it and inside these div's you can just put the url that the user submitted instead of the content that url points to. [If you can do this then I assume you wouldn't need to ask this question, so don't mind me treating you like a complete beginner]
How would you achieve this? Well you're definitely need:
Some sort of server side language (php is a good choice) that allows you to use the input from the user (The POST request from the form he/she submits),
Check it for correctness / clean up the input / supported websites, etc.
Save this information somewhere (a database) so that you can get it back later.
The next steps would be to now get the information from the database and show it on your gallery page like you want it. This involves:
Getting whatever subset of information you want to display on a particular page from the database. Perhaps only cat related things or something, I don't know.
Just displaying it in your div's using a for loop or something.
.
foreach ($subset as $url) {
echo "<div>$url</div>";
}
Then the last step would be to convert these links into actual videos / images or whatever depending on the type of link. This can be done both client side using Javascript / server side using php or some other language.
This is going to be a lot of manual work, looking through every websites api and figuring out how to convert a url into a video for example. Images are easy but they may be hotlink protected so you might have to go through an API there as well.

Deleting dynamically created button

I am making an English to hindi transliteration webpage that works offline. I have used HTML & javascript so the file works on all browsers across all OS.
I have added support for remembering words used via a cookie provided the user works on same computer, same browser every time.
As the user types word , buttons are dynamically created which suggest on basis of database stored in cookie. Is there a way I can associate action on right clicking a dynamically created button ?
Also , I want that - the dynamically created button should vanish on right clicking it ?
I want this because , if user wants to remove an erroneous entry from his vocab database (which is in a cookie referred above).
Currently I am able to remove all dynamic buttons in one go using
id-of-span-which-holds-dynamic-buttons.innerHTML = '';
A lengthier way would be to remove all buttons , then pop out word from database & recreate suggestion based on current database. Is there a simpler way ?
Where can I post my web page code (>51KB) if somebody wants to see what I have been talking about?

This is a really bad idea. It incurs a big overhead in every HTTP request - and eventually it will get to apoint where the requests get too large foer the server to cope with - then bad things can start happenning. HTML5 has proper support for local storage. Use it.

Have a look around the web - do you see anything similar implemented anywhere? I never have. Trying to take over the right mouse button is a bad idea.

Make javascript mandatory in web application?

I am building a web application that will have a fair bit of forms. The html forms are generated using php.
One of the things I came across is this:
I have a drop down box for the user to select his country. Once he selects the country, a call is made to the server to fetch a list of states within that country and populate it in a drop down box.
Initially, I thought I could provide 2 options:
An enhanced jquery version where ajax is used to fetch the states and the populate it in a drop down.
Where javascript is not availiable, the whole page is submitted to the server and then rerendered with the new states in the drop down.
However, onChange() requires javascript. So if someone where to visit the form without javascript enabled, there's no way we can deal with the second option, since javascript is required to submit a form using onChange().
What are some ways to deal with this? My only solution at the moment is to just make javascript mandatory. Users without javascript enabled will see a message saying that the page will not work properly.
Some sites:
Hotmail.com - Refuses to show anything except a "javascript is required message"
Facebook.com - Tells us we should use the mobile version of the site.
Google Maps - Does not work. No message to say javascript is required.
Gmail - Falls back to basic html.
Google account - Does not work. No message to say javascript is required.
Is it acceptable to require users to have javascript enabled at the current state of the web (august 2011)?
Just came across this possible solution:
http://cita.disability.uiuc.edu/html-best-practices/auto/onchange.php
I could perhaps add a button which the user can use to select their country. This should allow us to reload and render the form with the states drop down without any javascript.
You can provide a drop-down of states and tell the user to leave it blank if not applicable. If JavaScript is enabled, it can remove the drop-down until a country where it is applicable is selected.
No, it is not acceptable to require JavaScript; many security-conscious users use NoScript, for example, and would prefer not to turn it off.
By default you should load all possible values into the second dropdown, then clear them out on page load with Javascript. That way people without Javascript enabled can still choose the correct option.
I'm guaranteed to take flak for this, but whether you support no-JS or not should be your call. If you think your userbase is likely to have a sizeable portion of people who disable JS, then you should give them a site that works, but not optimally. If you think most of them will be running with "normal" (air quotes are important there) browsers, then you may consider dropping support for no-JS users.
I am NOT a professional developer, so take my input accordingly. Here are my observations:
I support a website for a wedding cake vendor. Upon observing the competition, all the more appealing sites are embellished (tastefully) with slideshows, dropdowns, animations, interactive form validation, etc.
When scouting for methods to incorporate these features into our site, I found that mostly every classy method was based in javascript.
Figuring it was better to present ourselves as the classy act we are (humble smile), I have decided to require users to have javascript enabled. We've been up for 7 years, and I have not received any complaints. All work on mobile devices.
A compromise option is to start with your State drop-down populated with the states of whatever country your business is in, e.g., all US states, with an extra option (preferably at the top of the list) that says "Other, non-[yourcountrynamehere]". Next to the State drop-down have a text input where the user can type the name of their state if it's not in the list. If JavaScript is enabled then on document-ready you can hide the text input and go with your Ajax solution. Without JavaScript the user has a fully functional page that doesn't even need a reload.
What I ended up doing is to add a button beside the drop down that says "select country". Users without javascript will see this button. Upon clicking it, the page will reload with the list of states rendered.
For users without javascript, this button is hidden, and selecting a country will automatically render a new drop down containing the relevant states.

How do I get dynamic (sections appear as they're being chosen) forms on "dumb" WAP phones (no Javascript)?

my site page's goal is to get information from a fairly complex (but concise) form. Ease of use is a big deal for me so when I tested the form on a WAP emulator, I was disappointed to see nothing happen when I clicked on radio buttons that successfully display the correct portion of the form on normal browsers, including the iPhone's. I've realized that this is because the code in the page is javascript and most dumb WAP phones don't support it. When I implement javascript, it's so that form options below a radio button don't show up until they are selected, and I know what you're thinking - "just make default forms options pop up" - but I couldn't figure out how to do that without ruining the whole appearing/disappearing act.
I suppose I could ask the browser if it supports javascript and redirect it to the javascript-enabled page if it does, or one without dynamic stuff if it doesn't... I wish there was a better option but how would I do that? BIG thanks in advance!
you could either use <noscript> to display the whole form on "dumb phones" or you could make some "config wizard"-like thing, like showing the radiobuttons on one page, submit it, and then (using php/ASP/whatever) send only the fields that depend on the previously checked options.
