Responsive Site - Load html based on dimensions - javascript

Is there any JS library that can help load different html files based on the dimensions? I guess this would be a mixture of responsive and adaptive, not sure if that's kosher.
Basically I want the site to show a different top menu on a phone.

Instead of arguing with you about how you're approaching the problem, I'll say that yes, there are JS libraries that could help you out.
There's a good writeup about enquire.js at http://css-tricks.com/enquire-js-media-query-callbacks-in-javascript/. This one lets you set callbacks for breakpoints.
Another you might be interested in is breakpoints.js which, similarly, will let you write jQuery to be executed at certain breakpoints.

Is there a reason you'd want to avoid doing this with a purely responsive design? You could include both a phone navigation and desktop navigation, then hide/show via CSS based on browser dimensions.

I agree with #Kolink's comment..
But if you want to do this anyway I would suggest enquire.js.
You will be able to do something like this:
enquire
.register("screen and (max-width:50em)", function() {
// Load top menu content 1 via AJAX.
// Show content menu 1
})
.register("screen and (max-width:40em)", function() {
// Load top menu content 2 via AJAX.
// Show content menu 2
});

The ideal situation is to load just an HTML and change the CSS rules applied to it through responsive design.
If you want to have different HTML versions, then you should redirect to another URL if the request comes from a mobile browser. Look at the following link with different recipes depending on your platform:

dynamic serving mobile & desktop website using bootstrap (js, html)

I originally designed the whole website (single page) responsive, readapting simply using css and some inline classes from bootstrap 4.
Now i found myself in need of redesigning the whole desktop version (or let's say with a very different structure from how it currently looks on mobile).
So I'd like to keep the html i have and keep using it for mobile, and modify a copy of it and use it for desktop.
The easiest way i thought has been to keep a single index.html file as now, duplicate the whole index.html inner part (between the div with class="page", which basically comes right after body) and set one of them to class="page d-none d-lg-block" and the other one class="page d-block d-lg-none" , using bs4 classes to show/hide content based on screen size.
I have various inline js functions and other functions in js files which refer to ids, so my feel is that creates errors because js see same ids twice or some stuff appears as the page load (due to the bs4 inline class to show the content), but just to be sure does anyone know if this is a correct thing to do (also SEO wise)? Or will it mess with the javascript doing so?
Make an existing page to become responsive is not an easy thing, but its much more worth than using a workaround to hide in small and hide in large breakpoint.
The reason is because:
You will have redundant component, means your app size will be doubled after you make it responsive,
and if you use static content without database, you need to maintain the content in two place (small and large breakpoint).
Spend more time on learning grid layout, and implement it in the right way. It will become much more easier for you to maintain your web app in the future.

Dynamic Breadcrumbs using sections of page for hierarchy

Working on creating a dynamic breadcrumb plugin using either jQuery or Javascript, and I do not have the knowledge to make it change dynamically while you scroll the page.
So we have a fixed header element, that will house the navigation and breadcrumbs.
While scrolling down the page, I would like the breadcrumb navigation element to change based on what section I am scrolling past.
Is this possible?
I appreciate any help or suggestions.
I believe this is possible. You can use <name> or <id> tags similar to the way you want to direct someone to a certain part of a page.
I would use those to determine whether an element is in the viewport or outside of it.
If you are okay with using a plugin you should go with the JQuery isInViewport plugin :

You can also take a look at the raw code and change it to your liking.

Embedding dynamically sized webpage with javascript

Okay, so first some background info: I am trying to embed a webpage within another page. The sub-page is basically a small web application written in javascript and html that takes in several screens of input (radio buttons, text boxes, etc.) and gives a screen with results at the end. Each of these screens can be a different size.
There are two methods I have tried using to do the embedding:
1) Copy all of the html and javascript from the sub-page into the main page and stick it in a div/table/whatever.
2) Keep the sub-page in its own file and embed it using embed/object/iframe.
Using the first method the page behaves as it should; the only real problem (aside from being kind of a messy solution) is that the sub-page I am embedding is actually generated by an external application, and every so often the page is replaced with a newer version. This more or less rules out using the first method as a long-term solution.
Now the second method has its own problems. Since the embedded javascript page changes in height, the frame that is holding it needs to vary in size with it. I'm able to change the size using any of the solutions given here, however these do not update the size of the frame as the user progresses through each screen.
The closest solution I've been able to come up with so far is using a document.onclick handler to catch any clicking which might cause the next screen of the sub-page to come along. The handler pauses for a very short time (to allow the next screen to come up) and then calls the necessary resizing function. However this feels like a very hacky solution, and there is also a slightly noticeable delay during with the scroll bar shows up on the side of the frame when it hasn't expanded yet to fit the new content. I'm thinking there must be a better way to do this.
If the file is on the same server/domain, you could just load it in with jQuery. Here is some jQuery code:
<script type="text/javascript">
$(document).ready(function() {
$('#id-of-div').load('/path/to/page.html');
});
</script>
Just change id-of-div to the id of the div that you want the page to be loaded into and change /path/to/page.html to the actual URL to the page. (you don't need the domain of it, just the path to it)
I hope this helps.

Dynamic content with JavaScript which allows linking

Let's say I want to create a website that contains one page. All the content is dynamic and generated using JavaScript with DOM replacement. The good thing about this is that it creates a better user experience, especially for applications that contain catalogues (online stores, galleries, etc). The problem now comes with linking. Let's say I'm browsing the site and I feel like sharing that particular thing I'm looking at with someone, but the problem is the link is always the same since it's JavaScript that's doing the magic. So the question comes: how can I create a fully JavaScript run website while maintaining the ability to link?
Now there's hash linking, but I'm failing miserably. I've tried overriding all <a> tags, changing the hash, and preventing the default action like so
$("a").click( function(){
window.location.hash = $(this).attr("id");
processHash();
return false;
});
Yet, it will randomly scroll my body for no reason.
I'd like some insights on the restrictions of linking in a fully dynamic website. Thanks.
Here is one simple thing you can do:
window.onload = function () {
processHash();
}
or it can be using jquery $(function () {...});
what happens here is when the page is loaded example http://www.example.com/#some-link
the page content is loaded first then your function that handle links processHash(); will do its work
not even the new and shiny jQuery mobile library is 100% ajax, but it's close. Obviously with a very modern browser, checkout this doc site done in jQuery mobile: http://jquerymobile.com/test/
If you dig in the docs a little you see how they use hash linking with the framework and html5 data-content="page"
each <div data-content="page">Is an independent page, if I remember right</div>

JQuery instant addClass or hide class

When adding JQuery to hide a class it of course waits for the page to load then hides the class, same thing for 'addClass'. There has got to be a better or faster way for it to 'load' as the page is loading. Anyone know of any ideas? I have given my sites JQuery scripts below with links to see them in action:
Hides sub filters: Link to example of my script to hide sub filters (notice left navigation filters)
if(jQuery('.refinement_category_section').length){
jQuery('.refinement_custom_category_section').hide() &&
jQuery('.refinement_filter').hide();
}
jQuery(document).ready(function(){
if(jQuery('.refinement_category_section').length){
jQuery('.refinement_custom_category_section').hide() &&
jQuery('.refinement_filter').hide();
}
});
OR
Adds a Class:Link to example of my script adding Class (notice left navigation filters)
$('.refinement_brand_section').parent().addClass('filterresults');
Using Firebug, it appears that the issue is with the number of images that you are loading. My suggestion is to dynamically load pictures for your items using javascript after applying your style changes or have a smaller number of items on the page (or both). This will result in a degraded, but still functional interface for non-javascript users. For javascript-enabled browsers, you can adjust how and how many images are loaded to still achieve a nice effect.
You should also use sprites for your small interface elements so that you're downloading a single image and using CSS to display various portions of it. Combining your javascript files and stylesheets for your production site would also help quite a bit -- you've got 20+ js files and 13+ stylesheets, each of which requires a separate request. You might want to run YSlow and follow it's other recommendations.
you can add CSS rules to hide these classes and then change it after jquery loads
.refinement_category_section, .refinement_custom_category_section, .refinement_filter {
display: none;
}
