Why does my Flask app not render CSS if I don't clear my cache?

由 强颜欢笑 提交于 2021-02-04 08:35:06
问题 I've been using Flask and have linked the html I'm rendering to a css stylesheet. I've noticed that whenever I update my CSS code, I have to clear the cache in order to get it to update on the webpage. How can I fix this? 回答1: I assume you are loading your CSS files with something like: {{ url_for('static', filename='some/file.css') }} For this to refresh immediately in development, you should set the following config var to -1 : app.config['SEND_FILE_MAX_AGE_DEFAULT'] = -1 As @Matvei states,

问题 This question already has an answer here : Destructuring assignment in while loop in ES6 function doesn't propogate out of loop? (1 answer) Closed 4 years ago . I am simply using es6 to reassign variables a & b. Why do I get an error if I leave the semicolon off of the a and b declaration and assignment statements? Does the parser try to pull a property out of 2 if the semicolon is left off? let b = 2[a, b]...? Works: let a = 1; let b = 2; [a, b] = [b, a] Error: let a = 1 let b = 2 [a, b] =

问题 I have a sliding curtain overlay that I added to my website from W3. Everything works great in FireFox, but when I click on the buttton to open the overlay on Google Chrome, the screen shakes for that instant of clicking the open or close button. Which is essentially running a javascript function that sets the <div> container that has the z-index overlay stylings' width from 0% to 100% and vice versa. /* The Overlay (background) */ .overlay { /* Height & width depends on how you want to

由 廉价感情. 提交于 2021-01-29 17:49:04
问题 I'm trying to get a page to refresh when navigated to from the back button. From what I understand after reading around a bit I should just need to mark the page as uncacheable but I can't get any browsers to refresh the page. These are the headers I've currently got: Cache-Control:no-cache Connection:keep-alive Content-Encoding:gzip Content-Length:1832 Content-Type:text/html; charset=utf-8 Date:Mon, 07 Jun 2010 14:05:39 GMT Expires:-1 Pragma:no-cache Server:Microsoft-IIS/7.5 Vary:Accept

window.history.back() Navigation Issue on Firefox?

由 痞子三分冷 提交于 2021-01-29 14:55:48
问题 I am currently using a script containing window.history.back() on my site. While it generally works, it occasionally jumps at times, and sometimes navigates back 2 pages instead of 1. Is there a better, or more up-to-date way to implement this code? I've currently placed it inside the <head> tag. <script type="text/javascript"> window.addEventListener("pageshow",function(event){ var historyTraversal=event.persisted|| (typeof window.performance!="undefined"&& window.performance.navigation.type

Blocking mixed content from potentially trustworthy origins (127.0.0.0/8)

由 放肆的年华 提交于 2021-01-29 14:43:48
问题 Mixed content isn't blocked for potentially trustworthy origins, including IP addresses from 127.0.0.0 to 127.255.255.255. Can browsers be configured to block mixed content for such addresses? This would make local testing easier. 回答1: I have found no browser settings to treat potentially trusted domains as untrusted, BUT here are several options to make 127.0.0.1 and untrusted domains behave the same, or to generate a report of items that would normally generate a warning.

Detect IE version from Apache, in case of compatibility mode

由 好久不见. 提交于 2021-01-29 12:59:10
问题 If a webpage is retrieved from a website in the Local intranet zone, IE7 mode is used. -MSDN So that's what happening with us. Client has set the option to "open intranet sites in compatibility mode". So at their place our application loads in IE7 mode. Is there any way by which I can detect whether the client is running his IE in compatible mode? As far as I know if the browser is in compatible mode then it sends IE7 user-agent string to Apache. So I can get that document mode is IE7, but I

Why is my code slow in safari desktop only?

由 与世无争的帅哥 提交于 2021-01-29 07:30:02
问题 I'm building a website that uses a few animations/libraries, AOS, simpleParallax and slick are the main ones. The website seems to run okay everywhere except Safari desktop. It runs fine in Chrome, Firefox, Microsoft edge, Opera, and it also runs fine in Safari on mobile, but it's extremely laggy, and choppy on Safari Desktop. This is the function I use for the sliders on the 'services' and 'faq' pages // slider (function () { var work = $('.js-work'), sliderWork = work.find('.js-work-slider'
