cross-browser

问题 So we've got some old-school Firefox extension code that uses the DOM3 methods get/setUserData() to pass around data in the DOM. Unfortunately, these have been deprecated in DOM4, so Firefox is planning to drop support for them, and Chrome never supported them in the first place. Is there a cross-browser replacement? jQuery's $.data seems to be an option, but 'pure' JavaScript would be preferable. 回答1: So in the end we decided to go with jQuery after all, the core library is only around 75k

问题 Does $('#idOfLememt').outerHeight(); yield same result for all browsers? Any thing different for IE7? 回答1: Just go to http://api.jquery.com/outerHeight/ with the different browsers you want to test and see for yourself (on Mac OS X so can't check IE for you). It looks like the DOM in the demo has all possible styles that would affect this included. Most of the time you can rely on jQuery to do it's thing and give you consistent results across browsers, that's one of it's main reasons for

问题 on a click event, I am running this code: win = window.open(a.href); i = setInterval(function () { if (win.closed) { /* do things */ } }, 250); this works fine in Firefox and Chrome, but in IE (9) it says that win is undefined or null. How can I work around this? EDIT: The window IS opened correctly in IE, it's just that a reference to it is not saved in win like it is in Firefox/Chrome. 回答1: Add name to the window: win = window.open(a.href, "myWin"); 来源： https://stackoverflow.com/questions

问题 So I'm having major trouble with styling radio buttons and as such I've managed to get it working perfectly in Chrome, a tiny bit in Firefox and not at all in IE. This is the expected look (in Chrome): This is how it looks in Firefox: And IE...

问题 Underscore.string seems to provide nice features for javascript string manipulation. It seems to have all the good points: license : MIT dependencies : none, it is an extension for Underscore.js but it can be used as standalone, without underscore.js weight (minified & gzipped): 4KB community, contributors: 58 contributors on Github history, contributions: since mid 2010 on Github, contributions seem rather stable although pretty quiet since 2014 Except one point for which I am missing info:

问题 Usually when I make a gradient I use the colorzilla gradient edtior. By default it generates the CSS for you. Here is an example: background: #1e5799; /* Old browsers */ background: -moz-linear-gradient(top, #1e5799 0%, #2989d8 50%, #207cca 51%, #7db9e8 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#1e5799), color-stop(50%,#2989d8), color-stop(51%,#207cca), color-stop(100%,#7db9e8)); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top,
