I made a Pwa with Flutter Web and I set as color on the whole project: # 8C3144. On Index.html I have black-translucent so also the status-bar in ios became # 8C3144, but it continues to remain black. I don't understand what I need to change, I don't think the problem is in the Flutter project

When I change the pages without loading them in the cache with service workers there are no problems when I go to save the pages in the cache they are no longer found both online and offline. The problem occurs only with pages and not with other elements such as .jpg .png .js .css and some .html elements
When i go to another page after i saved it in the cache

Site structure
what am I doing wrong? because I would like my site to work offline too but not being able to load the other pages it works only in the home
I would like to get the parameters in a URL and use them to generate an og:image meta tag in my SPA. The specific purpose is to have a dynamic thumbnail for a given url. The idea is for crawlers to be able to find the appropriate thumbnail.
example URL:
https://my.app/#/post?uid=abc&pid=123
These two parameters will not necessarily always be included. I hope it won't cause an issue.
My understanding is that crawlers generally only check the html for metadata. How could I include a bit of code in my html before the metadata? (I am relatively new to HTML)
Would I be able to put a script in the head tag? Are variable in the script available outside of the script? Can I use variable in the URL address of my og:image tag?

I was able to put a script before the meta tags and used window.location.href to get the URL. I used URLSearchParams to extract the parameters. However, I can only get the second parameter and not the first. If I add an '&' before the uid it works, but makes the url look weird... "?&uid"
<script>
const queryString = window.location.href;
const urlParams = new URLSearchParams(queryString);
const uid = urlParams.get('uid')
const pid = urlParams.get('pid')
if (uid != null && pid != null)
document.getElementById('urlThumb').content = `https://my.app/posts%2F${uid}%2F${pid}%2Furl_thumb.jpg?alt=media`;
</script>
I am looking to scrape player prices on https://www.fanteam.com/participate/138905/new/e30= using Python and Selenium libraries. I have used the following code:
url = 'https://www.fanteam.com/participate/138905/new/e30='
options = webdriver.ChromeOptions()
options.add_argument('--lang=en')
driver = webdriver.Chrome(chrome_options=options)
driver.get(url)
But I can't get all the players with prices, because I can't find any element on the page(see the picture below
players with prices).

Any code like
el = driver.find_element_by_xpath("//div[#class='player-list']")
return me the error:
NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//div[#class='player-list']"}
But when I inspect an element I can see it in the browser.
How to click any element on the page?
The website you are trying to scrape has a shadow-DOM in its html and any html present inside it cannot be accessed and that is the reason you are getting NoSuchElementException.
Currently, selenium does not support the shadow DOM automation, so you need to use javascript in this case to scrape the data.
To get the data using javascript, you can use:
JavascriptExecutor js = (JavascriptExecutor) driver;
String return_value = (String) js.execute_script("return document.getElementByXpath('xpath').innerHTML");

I used a Loopback/Polymer starter kit I found as a starting base for an application, but it does not seem to work on browsers other than Chrome (i.e. Firefox/IE/Safari). The demo for the starter kit code works in other browsers, so I know it must be possible, but I am having trouble converting my code into the structure that works. I am wondering if anyone would have any insight as to why it does not work with the structure I have in place from my index.html. It doesn't read my <application-polymer> element or native HTML elements (if I add them in) on the other browsers.
I have the webcomponents.js file imported in, and my elements are all inside client/element directory and linked to client/elements/elements.html. It works perfectly in Chrome, but no other browser. Please help!

The link to the full starterkit that this application is based off of is here:

The index.html structure is different (trying to import custom web components from elements/elements.html instead of creating them all inside the index.html which is unrealistic for a sophisticated app), which is why I am having issues.
I'm not sure what you have there, but it doesn't appear to be the latest starter kit, which I believe now follows the PRPL pattern and loads the stuff much later in the startup cycle.
If you look at it, it tries to dynamically decide to load the web components polyfill dependant whether the browser supports web components or not.
<script>
// Setup Polymer options
window.Polymer = {
dom: 'shadow',
lazyRegister: true
};
// Load webcomponentsjs polyfill if browser does not support native Web Components
(function() {
'use strict';
var onload = function() {
// For native Imports, manually fire WebComponentsReady so user code
// can use the same code path for native and polyfill'd imports.
if (!window.HTMLImports) {
document.dispatchEvent(
new CustomEvent('WebComponentsReady', {bubbles: true})
);
}
};
var webComponentsSupported = (
'registerElement' in document
&& 'import' in document.createElement('link')
&& 'content' in document.createElement('template')
);
if (!webComponentsSupported) {
var script = document.createElement('script');
script.async = true;
script.src = 'bower_components/webcomponentsjs/webcomponents-lite.min.js';
script.onload = onload;
document.head.appendChild(script);
} else {
onload();
}
})();
// Load pre-caching Service Worker
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('service-worker.js');
});
}
</script>
I suspect you are not correctly initializing the polyfills for non chrome browsers
I recommend actually using the polymer-cli from creating a framework as described here
https://www.polymer-project.org/1.0/toolbox/
var myApp = angular.module('myApp',['ui.router'])
myApp.config(function($stateProvider, $urlRouterProvider){
// $urlRouterProvider.otherwise('/home');
$stateprovider
//Home states and nested views
.state('home',{
url: '/home',
templateUrl: 'index.html'
})
});

Here is my HTML and app.js I am working with UIRouter. I am getting an error of injector module, but unable to figure it out. I am new to AngularJS, so please help me out. And yes, my ng-include too is not working. No results are displayed when I run my index.html file.
There is a working plunker
The casing is essential. It is $stateProvider not $stateprovider. This must be the state def:
var myApp = angular.module('myApp', ['ui.router'])
myApp.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/home');
//$stateprovider
$stateProvider
//Home states and nested views
.state('home', {
url: '/home',
//templateUrl: 'index.html'
template: "<h1>hello from home</h1>",
})
});
Check it here
NOTE: when you develop... do NOT use min versions. Only full can give you nice and easy to understand exceptions...
$stateprovider should be $stateProvider
