问题 I believe the title is pretty self-explanatory but still, maybe, I should ask in detail. I'm building a WYSIWYG editor and I'm really at the beginning of it. So, I realized that maybe knowing the pros and cons would enlighten me. Basically, my question is, since I want an editor that would work at least with 90% in all major browsers, how further I can go using contenteditable within a div and what are the cons and pros of using contenteditable when compared with designMode and iframe?

问题 I have a css conflict, so I have to go against an absolute positioning property that deals with some class .myclass . But in one case, I want a div with .myclass class to have a no absolute positioning. So I put position: initial , which works in Chrome, but is it cross-browser?

问题 So I am trying to work out the differences between link.click() and var event = document.createEvent("MouseEvents"); event.initEvent("click", true, false); link.dispatchEvent(event); As far as I can tell these should be the same things (however working with my jsfiddle example of exporting a csv from a URI this is not the case as they perform differently from browser to browser) Using .click() with firefox the popup to download the csv will not show (it will in chrome) see example -> http:/

问题 I'm looking for a way to reuse one NUnit test suite without duplicating the entire suite for each browser. It seems like I would need a new fixture for each browser.

问题 I would like to know is querySelector supported by all browsers? is not what's alternate for it to use? I have tested it with IE8, FF3, Chrome 4. Its fine for me. I do not have old browsers.
