hidden

问题 I recently added some swift code inside an objective-C project and I am facing something strange I cannot sort out. I am using the Searchbar (from Ray tutorial) that I customized. In the cellForRowAtIndexPath method, I can customize my cell labels and everything works fine. The only thing is that I cannot hide some imageViews according to if (BOOL) conditions. Something must be wrong with my swift code since I can hide those image in Objective-C files with the same if (BOOL) conditions. Just

问题 Hey all, Newbie here, so please forgive my approach and specifics. I'd appreciate some help! I'm working on an image gallery that's got three sections, of which only one will be visible at a time. At the top of the page there are three links that I want to toggle one of the three sections to show while hiding the other two. The code I've written is poor and works only from Link 1 to Link 2 to Link 3, but not backwards or from link 1 to 3, 3 to 1, etc. Thanks for your help and advice! HTML:

问题 I've got hidden divs that my navigation menu shows/hides. When showing/hiding the divs, the corresponding menu option is underlined; meaning the former div fades out, the current div fades in, and the underline follows. The underline does not hide when you close a div by re-clicking on its name in the menu. So ideally the underline will dynamically be added/removed following the dynamic div toggling. Thanks for your time and patience! HTML: <div id="nav"> <a class="home" id="show_brand" title

问题 Test this simple line in any HTML: <a href="anything"><span style="visibility:hidden;">insible text here</span></a> (you can test it directly from here: http://jsfiddle.net/wqS3E/ ) In Firefox and IE you can click the link (even more, you can see the default underline decoration). But in Chrome (v 13.0.782.220 ) is not possible to click/see the link. Is this a bug in Chrome or my CSS is not correct? I have a <li> element with a background image, and some <li> are links, and I want to be able

问题 Just wanted to know if it is possible to create a hidden window using javascript? 回答1: You can create an iframe var element = document.createElement("iframe"); element.setAttribute('id', 'myframe'); document.body.appendChild(element); You can hide an iframe by setting its width and height to zero or by setting its visibility to hidden in the stylesheet. 回答2: You can also create a new window visible only in taskbar with this workaround: window.open(path.html,'_blank', 'toolbar=no,status=no

I'm on a website using python and selenium chrome browser and trying to log into a website which has the following HTML where you enter the username or email: <div> <span class="g-hdn" id="1986367435LabelSpan"><label for="1986367435">Email or username</label></span> <label for="1986367435">Email or username</label> </span> <span> <input size="40" maxlength="64" name="1986367435"

问题 I have a question: I have a listview (from custom adapter) with a searchbar on top of it. Everything works ok, the only thing I need is when opening the activity to keep the listview hidden, or invisible, until the search has started in the searchbar (in other words, to keep the listview hidden until I start typing something in the searchbar). You can find the code here: How to start new intent after search-filtering listview? Plus a suggested solution, which unfortunately did not work, you
