I'm creating a single-page site, and I came across a problem that I can not solve. I have my menu with "Home | Blog | Contact" etc, change the URL with the javascript without updating the page with the code below:
window.history.replaceState({url: stgUrl}, "", stgUrl);
so I can see that the URL is modified correctly, the problem is that my site is in two different languages, and I want to put something like "/pt/" e "/en/" so the user can better visualize what language is browsing. The problem is that when I do this:
window.history.replaceState({url: stgUrl}, "", '/en'+stgUrl);
I get file upload errors, such as site images(Get 404: Not Found), which are not finding the path correctly anymore, because of '/en'.
since the changed url looks like this: mysite.com/en/
I would also like to add comments to blog posts on the site, and I saw that to add Disqus comments, I would need to have different urls for each post, so I can better control the comments, it's also something I do not know how to do.
obs: my site will be hosted without access to a server, so everything should work on the client, like a static but one page blog.
And how do I update the page with the url changed without receiving a 404? I would like to go to the home page for example, or update and maintain the current page.
So my question about urls comes down to three questions:
1 - How to change the url with "/pt" and "/en" and not receive 404 for images not found?
2 - How to change the url in order to generate comments from Disqus?
3 - How to update the page with the url changed without receiving a 404?

everyone. I am making a website with t-shirts. I dynamically generate preview cards for products using a JSON file but I also need to generate content for an HTML file when clicking on the card. So, when I click on it, a new HTML page opens like product.html?product_id=id. I do not understand how to check for id or this part ?prodcut_id=id, and based on id it generates content for the page. Can anyone please link some guides or good solutions, I don't understand anything :(.
It sounds like you want the user's browser to ask the server to load a particular page based on the value of a variable called product_id.
The way a browser talks to a server is an HTTP Request, about which you can learn all the basics on javascipt.info and/or MDN.
The ?product_id=id is called the 'query' part of the URL, about which you can learn more on MDN and Wikipedia.
A request that gets a page with this kind of URL from the server is usually a GET request, which is simpler and requires less security than the more common and versatile POST request type.
You may notice some of the resources talking about AJAX requests (which are used to update part of the current page without reloading the whole thing), but you won't need to worry about this since you're just trying to have the browser navigate to a new page.
Your server needs to have some code to handle any such requests, basically saying:
"If anybody sends an HTTP GET request here, look at the value of the product_id variable and compare it to my available HTML files. If there's a match, send a response with the matching file, and if there's no match, send a page that says 'Error 404'."
That's the quick overview anyway. The resources will tell you much more about the details.
There are some solutions, how you can get the parameters from the url:
Get ID from URL with jQuery
It would also makes sense to understand what is a REST Api and how to build a own one, because i think you dont have a backend at the moment.

Im struggling to figure out the best way to redirect/rewrite urls with some pattern matching using javascript.
BACKGROUND:
I have a blog filtered by tag: http://adrtimesv6.squarespace.com/library/?tag=The+Psychology+%26+Neuroscience+of+Mediation (select view as visitor if that comes up)
I have another area in the site called "Collections" where i load in groups of posts from the library in its own real page with other content in a more controlled environment with page titles and urls that are better for seo, like this: http://adrtimesv6.squarespace.com/collections/the-psychology-and-neuroscience-of-mediation. the posts are loaded in via a query that pulls in posts from the library that have a tag that matches the name of the collection page. this is working pretty well. the problem im running into is that when someone filters the blog posts by tag i want them to be redirected to the collection page rather than go to the blog filter page.
QUESTION:
What im trying to figure out is how to use jquery to redirect all the /library/?tag=[path] urls to /collection/[path] urls. To do this i think i need to use jquery to:
1) swap "/libary/?tag=" to "/collections/"
2) revise the rest of the path from the tag formatted path "The+Psychology+%26+Neuroscience+of+Mediation" to my collection formatted path: "the-psychology-and-neuroscience-of-mediation"
ADDITIONAL INFORMATION:
I am using a CMS so i dont have access to things like the .htaccess file. in the CMS admin settings there is a url redirect panel that allows me to list some basic redirects in this format: -> ... but trying this with the tag filter urls is not working.
Im mostly concerned with this redirect occuring when the user clicks on the tags listed at the bottom of the blog post - so i could use jquery to modify the href attribute in the tag listed for the blog post. just not sure how to write the pattern matching and rewrite the format correctly. ive tried a bunch of things but cant seem to get it.
or perhaps use window.location.replace somehow?
UPDATE:
In my particular case, i found that i could update my template code and json formatters so that the tag link href generated matches the url in the collection section - so my problem is solved ....however, i still wonder how i would do handle this for other situations.
basically, 1) how to use javascript or jquery to check if the url (either href on the page or the browser url) contains something, then replace that with something else, and then modify the full url so that it is a simple dashed url .... takes out all + signs and replaces them with - and removes the %26 for & characters to return a simple url string, etc, like: /here-is-the-path
On a single page, you can use this to forward a visitor to a new page:
window.location = "http://www.google.com"
You could add logic to use the same script on every page. For example:
if ( document.location == "http://adrtimesv6.squarespace.com/library/?tag=The+Psychology+%26+Neuroscience+of+Mediation" ) {
window.location = "http://adrtimesv6.squarespace.com/collections/the-psychology-and-neuroscience-of-mediation"
}
and so on. You could even add more advance string manipulation to handle every URL.
But doing a JavaScript redirect in this manner will not have positive SEO effects such as friendly URLs. It will not enable your web server to handle the new URL; if http://adrtimesv6.squarespace.com/collections/the-psychology-and-neuroscience-of-mediation returns an error from your web server, no amount of front end JavaScript will be able to fix that.
Doing this with JavaScript this would probably be a negative experience for your users, because they would first have to download the page from the first URL, then execute the JavaScript, and then download the page from the new URL.
Okay so there are solutions for this as in Modify the URL without reloading the page but I have one question regarding this.
So here is what I plan to do (let's assume my web address is example.com)
1. using pushState I plan to change the browser address to example.com/myprofile/myalbum. So to be clear, this new url may or may not exists but the browser address is changed regardless. In our case this url doesn't actually exist but we are using the address to mark a changed state of the webpage.
2. use ajax to load data regarding "myprofile > myalbum" to the same page.
But now here's the issue I have been thinking about. What if a user loads example.com/myprofile/myalbum directly on a, let's say, new tab. This page clearly throws a not found error because it doesn't exist.
So how do I load ajax corresponding to this fake url? For example http://www.usatoday.com/news/ seems to do this well (unless that's an iframe, which wouldn't be so nice).
You can add rewrite rules to your webserver, converting either specific URL's or some matching a pattern to something that your scripts can use to show the right page. You can have it rewrite the URL only internally, so the user still see the original URL in the browser. Such as:
RewriteRule /myprofile/(\w*) /index.php?path=/myprofile/$1
Different webservers will probably have different syntax, but they will be similar.
On my website, Like buttons are generated dynamically. The URLs associated with these Like buttons are links that automatically redirect (with htaccess) to its respective hashtag url (i.e. ".com/event/200" redirects to ".com/#event/200"). The issue is that I can't seem to set the title or image. When a page loads with a hashtag, a database is queried and then the page title, meta data, and other things are changed. Facebook seems to be using the metadata that's set before the database has had time to load and the content has been changed. Does anyone have any idea how I can solve this problem? I'd love to be able to set the title and image when the like button is loaded if there's anyway to do that. Here's my like button code:
<fb:like href='http://website.com/"+postname+"/"+data.id+"' send='true' layout='button_count' width='450' show_faces='true'></fb:like>
The URLs associated with these Like buttons are links that automatically redirect (with htaccess) to its respective hashtag url (i.e. ".com/event/200" redirects to ".com/#event/200").
That’s your error right there.
Since the Hash part of an URL does not get transmitted to the server, it’s only usable client-side. So redirecting to it server-side is a really bad idea, since you know nothing about the client’s capabilities (f.e. if it supports JavaScript).
Don’t do server-side redirects - make them client-side instead, via JS.

Note: The question is not how to fix the problem, as that is documented elsewhere on SO (e.g., Integrating Facebook to the leads to blank pages on some browsers / fb_xd_fragment).
1) What causes this, and under what conditions is it triggered?
2) More importantly, does this affect end users at all? For instance, how does this bug affect the URL shared by someone who clicks the FB Like button? If someone clicks the FB Like button from URL A, does URL A still get shared (but with "fb_xd_fragment" appended), or does URL A become your root URL (with "fb_xd_fragment")? In our logs, all the URLs appear as the root URL with "fb_xd_fragment" appended, so we're not sure if this is because people are clicking the Like button from the home page, or if all the shared URLs get morphed into the root URL.
Basically, what happens is whenever you use the JS API it opens your site in another iframe to use as a cross-domain receiver. What you can do is set a custom channel URL and it will use that instead. If seeing this bothers you, you can set a custom channel url.
