cross-browser

问题 I'd like to use document.referrer for an informal referrer check. Is this element cross browser compatible? Will any browser throw an error when trying to reference the document object? 回答1: The document.referrer property is described in the DOM spec: http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-95229140 So it should be supported cross-browser. However, you can easily detect if the implementation does support this property like if( 'referrer' in document ) { console.log(document

问题 I want to make a layout that satisfies the following conditions: 1) it has a block on the top whose height is up to its content 2) below it has a code-mirror and a block side by side, which fill in exactly the rest of the page in terms of height . I have made a plunker here. The problem is it works well in Chrome 57.0.2987.133 , whereas it does NOT work well in Safari 10.1 : the height of the code-mirror is NOT enough; it shows only 76 lines of the code rather than the correct 80 lines. Does

问题 I am designing an elastic layout which is used with a dynamic number of items. As you can see, the layout is fluid and the number of items per row changes with the resolution. I can put on any classes I want on the item when I generate them with PHP if this helps. Code http://jsfiddle.net/N3VRM/3 http://jsfiddle.net/N3VRM/3/embedded/result/ Problem I always want the left-most pink grids to align with the far left of the page and the same on the right side. Currently there is always an extra 1

问题 I'm trying to handle some logic on before unload and I don't want that logic to run if the user is reloading the page or going back. I've set up something like this. window.onbeforeunload = function(e) { if(window.event && window.event.clientX){ //IE //some logic } else if (e.currentTarget.performance.navigation.type === e.currentTarget.performance.navigation.TYPE_RELOAD) { // another logic } else if(e.currentTarget.performance.navigation.type === e.currentTarget.performance.navigation.TYPE

问题 I'm storing some custom data in HTML5 data attribute for Jquery processing. will the custom data attribute available in Older browsers? 回答1: The HTML5 datalist property is not available in older browsers (it can be polyfilled easily enough though). You can always use the standard getAttribute method instead of course, and data-xxx attributes on HTML elements are accepted by all browsers (as long as you're in HTML mode and not xHTML where they're invalid) But your question seems to be more

问题 Is there a way to debug javascript using Safari 3.2 in Windows Vista? I found a link to a debugger named Drosera but I can't get it to work because the information seams to be outdated. 回答1: Well, apart from the Error Console that can be opened from the Develop menu (which in turn can be enabled in (Prefences / Advanced / Show Develop menu in menu bar) there aren't many javascript debugging options in Safari AFAIK. Still, the error console is quite useful as it shows javascript errors and

问题 I have an iframe and I want to clear it, so I set its src to about:blank Then I wondered, does this work in all browsers? 回答1: It's a requirement for HTML5 implementations to support about:blank. As for non-HTML5 web browsers, it depends. WorldWideWeb, Lynx, and some other browsers don't support about:blank – it wasn't a standard then. The about:blank itself initially appeared in Netscape Navigator 1. Internet Explorer copied that feature from Netscape, and other browsers copied it as well.

问题 Right now, we are trying to achieve consistent formatting of textarea elements, across Safari/Chrome/Firefox/IE on Mac and Windows. I believe this may be a rabbit hole, since any combination thereof could produce formatting in a slightly different way -- maybe one combination adds a bit of padding to a div here differently than the others, another one breaks multi-line text there differently than the others, and so on. Instead of using textarea (or div ) elements, can we achieve pixel-perfect
