Is quirks mode relevant in 2011?

一笑奈何 提交于 2019-12-04 03:09:07
问题 With all the latest browsers like IE9, FF4, ever updating chrome, etc., do we still need quirks mode? If yes where is it useful? In which scenario? 回答1: No. You should never use quirks mode. It ceased to be of any relevance once IE 5.0 and 5.5 stopped being used. Those were the last browsers which did not support standards mode, so any sites which needed to include support for them would have needed to be able to work in quirks mode. However, IE6 along with all versions of all browsers

How to cache an HTTP POST response?

陌路散爱 提交于 2019-12-04 03:05:10
I would like to create a cacheable HTTP response for a POST request. My actual implementation responses the following for the POST request: HTTP/1.1 201 Created Expires: Sat, 03 Oct 2020 15:33:00 GMT Cache-Control: private,max-age=315360000,no-transform Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Content-Length: 9 ETag: 2120507660800737950 Last-Modified: Wed, 06 Oct 2010 15:33:00 GMT ......... But it looks like that the browsers (Safari, Firefox tested) are not cacheing the response. In the HTTP RFC the corresponding part says: Responses to this method are not cacheable,

I am trying to use Javascript in LESS to be compiled in phpstorm.. I am trying to create a function based off of a cross-browser implementation of opacity found at this site : link Specifically, I am trying to create a LESS function to recreate this piece of code: .crossbrowseropacity { /* Fallback for web browsers that doesn't support RGBa */ background: rgb(0, 0, 0); /* RGBa with 0.6 opacity */ background: rgba(0, 0, 0, 0.6); /* For IE 5.5 - 7*/ filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000); /* For IE 8*/ -ms-filter: "progid

Finding/setting css line-height defaults

僤鯓⒐⒋嵵緔 提交于 2019-12-04 02:57:24
问题 One strange thing I've noticed when trying to normalize my css across browsers is that default line-height properties for h-elements and other major tag types are different across browsers like Chrome and Firefox, and yet are not set at the user-agent level: http://codesearch.google.com/codesearch#OAMlx_jo-ck/src/third_party/WebKit/Source/WebCore/css/html.css http://mxr.mozilla.org/mozilla-central/source/layout/style/html.css Moreover, popular normalizers like normalize.css don't take care of

Help with footer always to bottom

最后都变了- 提交于 2019-12-04 01:57:54
问题 I know this has been discussed here many times, but none of the answers I found here, seem to address my problem. I have this variable (in height) layout, and wnat the footer to always stick to the bottom. I have used the min-height: 100%; to the container div, and got it somehow to always be in the bottom. trouble is, it's sinking too low to the bottom. I've put an example here: http://jsbin.com/erono3 As you can see, my footer is at the bottom, but will go too far in the bottom, and even

Is there any crossbrowser solution for playing flac? (or is it possible in theory to make one)

左心房为你撑大大i 提交于 2019-12-04 01:49:28
Not interested in silverlight. Flash/javascript/html5 solutions are acceptable. If you do not know such solutions, could you please say is it possible to make such that or not? Tico A simple Google search led me to these sites: Aurora and FLAC.js — audio codecs using the Web Audio API Introducing FLAC.js: A Pure JavaScript FLAC Decoder Believe it or not, it wasn't so hard. Almost forgot: Check HTML5Test to compare browsers performance/compatibility with the <audio> tag and it's siblings. When I had to play FLAC in-browser, my starting point was also the Aurora framework . However, the Aurora

Javascript strings - getting the char at a certain point

☆樱花仙子☆ 提交于 2019-12-04 01:03:31
问题 I have a variable: var text = "hello"; I want to get the 0 positioned character, so: var firstChar = text[0]; Simple. In firefox and chrome this works. In IE however i always get back 'undefined' Any ideas why this might be happening in IE? 回答1: Strings aren't accessible like arrays in IE (prior to IE9). Instead you can use charAt, which is available cross-browser: var text = "hello"; var firstChar = text.charAt(0); // firstChar will be 'h' 回答2: You can use .substr(). var firstChar = text

Differences in JSON.stringify result between browsers

爷,独闯天下 提交于 2019-12-04 01:01:22
When I JSON.stringify() the following code: var exampleObject = { "name" : "Žiga Kovač", "kraj" : "Žužemberk"}; I get different results between browsers. IE8 and Google Chrome return: {"name":"\u017diga Kova\u010d","kraj":"\u017du\u017eemberk"} While Firefox and Opera return: {"name":"Žiga Kovač","kraj":"Žužemberk"} I am using the browser's native JSON implementation in all 4 browsers. If I undefine the native JSON implementation and replace it with the one from json.org, then all browsers return: {"name":"Žiga Kovač","kraj":"Žužemberk"} Why is this happening, which result is correct and is it

Is oncontextmenu cross browser?

时间秒杀一切 提交于 2019-12-04 00:58:45
window.oncontextmenu = function() { return false; }; Will this work on all major browsers such that the right click will not be initiated? See this quirksmode page for a detailed compatibility table. QuirksMode has a comprehensive chart of support for the event. You can use it to decide if it meets your needs depending on browsers you support. 来源: https://stackoverflow.com/questions/7223143/is-oncontextmenu-cross-browser

What's the best way to detect if a given Javascript object is a DOM Element? [duplicate]

情到浓时终转凉″ 提交于 2019-12-04 00:26:33
This question already has answers here : Closed 5 years ago . JavaScript isDOM — How do you check if a JavaScript Object is a DOM Object? (32 answers) Say for instance I was writing a function that was designed to accept multiple argument types: var overloaded = function (arg) { if (is_dom_element(arg)) { // Code for DOM Element argument... } }; What's the best way to implement is_dom_element so that it works in a cross-browser, fairly accurate way? jQuery checks the nodeType property. So you would have: var overloaded = function (arg) { if (arg.nodeType) { // Code for DOM Element argument...
