I'm trying to make a audio player in Chrome with HTML5 and Javascript. But I got an error(file not readable) at the very beginning...
Below is my HTML code:
<head>
<meta charset="utf-8" />
<!-- Always force latest IE rendering engine (even in intranet) & Chrome Frame
Remove this if you use the .htaccess -->
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />

<!-- Replace favicon.ico & apple-touch-icon.png in the root of your domain and delete these references -->
<link rel="shortcut icon" href="/favicon.ico" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" />
<script src="js/jquery-1.6.1.min.js" type="text/javascript"></script>
<script src="js/fun.js" type="text/javascript"></script>
</head>
<body>
<audio id="player" controls="controls">
Please use Firefox/Chrome/IE9 to browse this page.
</audio>
<input type="file" multiple="multiple" id="fileChose" />
</body>
And below is my Javascript code:
$(document).ready( function() {
$('#fileChose').change( function() {
var fileList=this.files;
for(var i=0;i<fileList.length;i++) {
var reader=new FileReader();
reader.onloaded=function(e){
$('#player').attr('src',e.target.result)
}
reader.onerror=function(e){
switch(e.target.error.code) {
case e.target.error.NOT_FOUND_ERR:
alert("file not found");
break;
case e.target.error.NOT_READABLE_ERR:
alert("file not readable");
break;
case e.target.error.ABORT_ERR:
alert("aborted");
break;
default:
alert('generic error?');
}
}
reader.readAsDataURL(fileList[i]);
}
});
});
Can anyone help me with this problem? Thanks a lot!
In Chrome you can add: --allow-file-access-from-files to the Chrome command line to allow local file to be read from local HTML pages.
You can also bundle your code up as Chrome Extension and get local file access that way.
Or upload the HTML files to a Server as already mentioned.

In the HTML below, the line <script type="module" src="/src/main.tsx"></script> gives me a warning:
'script[type=module]' is not supported by Internet Explorer.Microsoft
Edge Tools (compat-api/html)'
I've no intention of supporting IE11.
I'm using VSCode Version: 1.64.2. How can I ignore this warning?

Based on the error source (compat-api/html), I assume you're using Webhint.
That rule supports configuring the supported browser list in .hintrc, so you could configure it to exclude Internet Explorer:
// .hintrc
{
"browserslist": [
"defaults",
"not IE 11",
⋮
]

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

I am working on a project in which i have to scrape images related to a keyword from a image site. When i search for any keyword on imgur(My choice for the image site), the results are shown as small thumbnails which when clicked open the main article with various images on it. My program for now makes a list of various links in the thumbnails and opens them one by one to download all images in it.
My problem is that when i inspect image element on the article it shows that the image is in class ".image-placeholder" but when i download the html by request method it does not show any such class available.
One of the examples is that when i request response object of article https://imgur.com/gallery/rfEAUDW.
I get below html:

Thanks in advance for all your help.
My code is:
import requests
from bs4 import BeautifulSoup
from pathlib import Path
import os
#UserInput for phrase to search.
phrase = input('Enter text to search: ')
finalphrase = phrase.replace(" ", "+")
print('Searching for ' + finalphrase + '.....')
#makes soup of the search page and collect all results as galleryElem
site = 'https://imgur.com'
res = requests.get(site + '/search?q=' + phrase)
soup = BeautifulSoup(res.text, 'html.parser')
galleryElem = soup.select('.image-list-link')
#For each thumbnail will open it and download its content
for n in range(len(galleryElem)):
imageLink = galleryElem[n].get('href')
res1 = requests.get(site+imageLink)
soup1 = BeautifulSoup(res1.text, 'html.parser')
imageElem = soup.select('.image-placeholder')
for m in range(len(imageElem)):
image = imageElem[m].get('src')
img = open(os.path.join(finalphrase, number, os.path.basename(image), 'wb'))
number += 1
for a in image.iter_content(100000):
img.write(a)
img.close()
You didn't use selenium. You used requests and bs4. If you have used selenium, you wouldn't have met this problem, because selenium executes javascript for you, while requests doesn't. And the website seems to load images with javascript.
An example with selenium can be found here.
You can check documentations of selenium for more information.
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");
References for the shadow DOM:
