Changing pages URLs without using route controllers

First of all, sorry for the lame question (probably). I tried to search for an answer but I'm not finding everything I need for my issue.
So... I have a bootstrap website and I am trying to change the page URLS to appear like this :
For example : www.site.com/AboutUs.html - to appear as www.site.com/about-us
I am using the pushState method for this as it follows:
var stateObj = { AboutUs: "about-us" };
history.pushState(stateObj, "About Us", "about-us");
So I get the needed URL address there (www.site.com/about-us).. so far so good. But on page refresh it throws an error stating "The requested URL /about-us was not found on this server."
If I hit the back browser button it goes to www.site.com/AboutUs.html again.(and it is supposed to go on the home page)
My question is :
What am I missing, am I supposed to make a controller and how ?
I am not using C#, I can probably use some help with PHP because I am not good at it. JavaScript / jQuery are welcomed.
Thanks in advance and sorry for the dumb question.
Happy days!

The point of pushState is to be able to say: I have modified the page with JavaScript, the new state is what you would get if you just asked the server for this URL.
You shouldn't use JavaScript for this problem at all. You just want to have a page appear at a particular URL.
You need to configure the server to serve up the content you want on the URL you want.
What am I missing, am I supposed to make a controller and how ?
You need something on the server to handle the URL /about-us.
"A controller" is something you would probably use if you were using the MVC architecture on the server … and it doesn't sound like you are.
More likely you will be wanting to use an Alias, a tool like mod_write, or simply moving the static file to a directory called about-us and renaming it index.html.

Facebook group chat - fetch complete chat content without paging

What I want
I want to be able to copy/paste the entire content of a chat to memory
so I can extract included YouTube urls from it.
What I know
As you may know, the group chat(s) run on a separate url and are loaded page by page. Normally you go to the previous page either by simply scrolling upwards, or by clicking on a show previous link (works differently on different devices I think).
Things I tried
Sadly I can't find the urls to either anymore, but ...
Add a script to Chrome console
The point was to add a script that went looking for the show previous link and clicked it.
Add a start=0 parameter to the url
This assumes you can find out the actual url, either manually or through something like Fiddler.
The idea was that you add something like ?start=0 to the url. This would cause the paging to start from the very first record and load all.
Both solutions didn't work.
Possibly this is because Facebook made these options obsolete. It's my impression that Facebook initially provided more dev options than it does now.
My question
What can I do to fully load chat content?

Not really sure what this has to do with C#, but i'll give a C# solution anyways. My solution would be to use something such as HTMLAgilityPack to get the InnerHTML from a page once it's loaded, although this will obviously require some type of authentication, so for this I suggest using something like a WebClient and sending along Auth credentials with whatever it is you're doing, OR just create a method to login, then use the same webclient to access chats via URL, use DownloadString() to get the contents of the page then using HTMLAgilityPack's methods to get the InnerHTML of whatever the chat box is called/indentified as.

Right now this is the nearest thing I can find:

There is a way to see your complete chat history on Facebook easily.
By this method you can also see Photos or videos you've shared on
Facebook. Your Wall posts etc. -- 'A copy of what you've shared on
Facebook' Follow these steps:
Go to 'Account Settings'
Click on 'Download a copy of your Facebook data' from bottom of General section
Then click 'Start My Archive' -- It may take a little while for gather your photos, wall posts, messages, and other information.
(Usually 20 to 60 minutes)
Once Archive generated Download it.
Extract and open 'index.html' from downloaded folder
Now you can see 'Messages' on bottom of the page, click it.
Done!
I got a response in my mail way faster than 20 minutes.
You will get a mail with a link to a zip file, containing your archive:
In the html folder you find: messages.htm
For that I can write a script that looks for YouTube URLs in that file.

PHP HttpRequest to create a web page - how to handle long response times?

I am currently using javascript and XMLHttpRequest on a static html page to create a view of a record in Zotero. This works nicely except for one thing: The page html title.
I can of course also change the <title>...</title> tag, but if someone wants to post the view to for example facebook the static title on the web page will be shown there.
I can't think of any way to fix this with just a static page with javascript. I believe I need a dynamically created page from a server that does something similar to XMLHttpRequest.
For PHP there is HTTPRequest. Now to the problem. In the javascript version I can use asynchronous calls. With PHP I think I need synchronous calls. Is that something to worry about?
Is there perhaps some other way to handle this that I am not aware of?
UPDATE: It looks like those trying to answer are not at all familiar with Zotero. I should have been more clear. Zotero is a reference db located at http://zotero.org/. It has an API that can be used through XMLHttpRequest (which is what I said above).
Now I can not use that in my scenario which I described above. So I want to call the Zotero server from my server instead. (Through PHP or something else.)
(If you are not familiar with the concepts it might be hard to understand and answer the question. Of course.)
UPDATE 2: For those interested in how Facebook scraps an URL you post there, please test here: https://developers.facebook.com/tools/debug
As you can see by testing there no javascript is run.

Sorry, im not sure if i understand what you are trying to ask, are you just wanting to change the pages title?
Why not use javascript?
document.title = newTitle

Facebook expects the title (or opengraph :title tags) to be present when it fetches the page. It won't execyte any JavaScript for you to fill in the blanks.
A cool workaround would be to detect the Facebook scraper with PHP by parsing the User Agent string, and serving a version of the page with the information already filled in by PHP instead of JavaScript.
As far as I know, the Facebook scraper uses this header for User Agent: "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)"
You can check to see if part of that string is present in the header and load the page accordingly.
if (strpos($_SERVER['HTTP_USER_AGENT'], 'facebookexternalhit') !== false)
{
//synchronously load the title and opengraph tags here.
}
else
{
//load the page normally
}

take content from WordPress page and deliver it to HTML via ajax

I have the following problem:
HTML blank page on server 1.
WordPress site on server 2.
What I need is to call the content from www.wordpress.site/sample-page/ to HTML page on server 1, but not the entire page, only the part that I can edit from wp-admin; so without header and footer.
Also, I don't know if there is any other method, but I need it to be done via JavaScript/jQuery or Ajax.
I've used Google, but is hard to get a tutorial for this, I've tried a lot of tutorials, but none is what I need, and I don't know that much JavaScript to make it work.
SO, can someone help me please?
BIG Thanks!
Andrei
L.E.:
I've found this working: http://jsfiddle.net/mdawaffe/hLWdH/
It is working as it is written, if I try to change the domain with mine, will not work.
What script do I have to implement on the server from which the content is called (taken)?
For more information, as you asked:
I have a HTML + CSS + JS template that I will use with phonegap (if you don't know about it, try it, it's very useful) to create a mobile app for Android, iOS, and BlackBerry.
Now, I have this site: m.trafficvoice.ro (I hope I can post links here).
In the 'live stream' page (it's called services.html), I have a HTML5 audio tag/player.
What I need, is to get from www.trafficvoice.ro/whatever-the-name-page, the content, but only the part that I can edit in WordPress (so without header and footer).
Why? Because in the future there will be more stream to add, and maybe some of them will be down due to unknown reason, so I need to update that page, without making an update for the entire app, upload it to the store, wait for approval, the client to download it, etc.
Big thanks!
Andrei

Could you just use an iframe instead? You could modify a template in your theme to not display header/footer and then use that in the iframe.

Sending google visualization chart to email

Can we send Google Visualization chart to an email client?
I tried to copy paste the javascript code while sending the email, but its been removed on the fly by gmail.
Thanks and Regards.

Disclaimer: I'm Image-Charts founder.
6 years later! Google Image-Charts is deprecated since 2012, and as an indiehacker, I don't want to rewrite from scratch an image generation backend each time I started a new SaaS to just be able to send charts in email...
That's why I've built Image-charts 👍 and added gif animation on top of it 🚀(chart animations in emails are awesome!!), no more server-side chart rendering pain, no scaling issues, it's blazing fast, 1 URL = 1 image chart.
https://image-charts.com/chart

I ran into this problem as well. In order to send a chart in email, you need to render it as an image because email clients strip Javascript.
If you're using Google Charts, you'll have to run the Javascript and then export it using getImageURI. To automate this, you need a headless renderer like puppeteer.
The solution to the problem is open source. I wrapped chart rendering in a library and web server: https://github.com/typpo/quickchart. This web service handles the rendering details, all you do is call the API with your data.
For example, define your chart in the query parameters:
https://quickchart.io/chart?width=500&height=300&c={type:'bar',data:{labels:['January','February','March','April','May'],datasets:[{label:'Dogs',data:[50,60,70,180,190]},{label:'Cats',data:[100,200,300,400,500]}]}}
The above URL renders this image:
Hope this helps!

Google charts could be published in 2 ways:
as an Image. Edit Chart-> Publish Chart-> Format : image. An image link is generated. This image link could be either used in any html page or could be embedded in any email.
as an Interactive Chart. Edit Chart-> Publish Chart-> Format : Interactive Chart. In this case javascript code has to be inserted. This could only be published in html pages. This could not be attached in email body as most email servers/clients do not process javascript code (AFAIK).

3.5 years later... :)
My team at Ramen recently spun out some internal functionality into a standalone product that does just this: https://ChartURL.com
You can generate charts on the fly using an "Encrypted URL" scheme, or you can send us huge amounts of data and return a Short URL that'll resolve to an image.
It was built on top of C3js.org so there's a ton of flexibility in what you can generate.
These URLs can be used in web apps & mobile apps, but the original intent was email charts so I hope this helps!

There is very little JS support in email clients. so you will have to use an image chart. But you could wrap the chart in a link to the svg version.

Doesn't Google Charts have an API where you can just build a URL and it returns an image - no Javascript needed? It certainly used to. If you can use that, then:
a) Just put the URL in the email and let the users email client get it
b) Fetch the image with CURL and attach to the email.
