removeclass

问题 So I'm trying to have a mobile menu that slides out on the left when an icon is clicked, and disappears again after you click outside the menu. Like this: http://codepen.io/anon/pen/LzJuq (old, see new codepen below) And it works fine on desktop and in Android's default Browser. On my phone, in Chrome, the menu will only open the first time. Each subsequent time it closes itself before it finishes opening. I can see that it tries to open... so I assume, because the #menu-icon is actually

问题 i have a very simple question, actually this is not the question, this is fixing the javascript mistake, anyway, here is the code: $(document).ready(function() { $('#accordion a.item').click(function () { $(this).addClass('selected'); $(this).removeClass('selected'); $('#accordion li').children('ul').slideUp('slow'); $(this).siblings('ul').slideDown('slow'); }); }); and the html: <ul id="accordion"> <li> <a href="#" class="item">BANKS</a> <ul>BLA BLA BLA</ul> </li> <li> <a href="#" class=

问题 I've already posted a question about jQuery toggle method here But the problem is that even with the migrate plugin it does not work. I want to write a script that will switch between five classes (0 -> 1 -> 2 -> 3 -> 4 -> 5). Here is the part of the JS code I use: $('div.priority#priority'+id).on('click', function() { $(this).removeClass('priority').addClass('priority-low'); }); $('div.priority-low#priority'+id).on('click' ,function() { $(this).removeClass('priority-low').addClass('priority

问题 I am developing a mobile site and want to use JS for nothing more than adding and removing classes. So, in the interest of keeping things nice and light I don't want to use jQuery. I have the following HTML: <div id="masthead"> <a href="index.html" title="Home" id="brand">Brand</a> <a href="#" id="openPrimaryNav">Menu</a> <ul id="primaryNav" class=""> <li><a href="index.html" title="Home">Home</a></li> <li><a href="benefits.html" title="Benefits">Benefits</a></li> <li><a href="features.html"

问题 I have a div and when I click it jquery adds a class which starts an animation running. When the animation stops (after 3 seconds) I want the class to be removed, so that when the div is clicked on again the animation will start over. This is only testing and only Chrome browser at the moment. Here is my CSS3: .spin360 { -webkit-animation-name: spin; -webkit-animation-duration: 3s; -webkit-animation-iteration-count: 1; -webkit-animation-timing-function: ease; -webkit-animation-fill-mode:

问题 Ok after hours and hours trying to figure out a way to do this, I have come up with nothing. I knew that I need the SVG jQuery plugin so I have that and have gotten the toggleClass() function to work, but I'm trying to remove classes from all of my group elements and then add another class to the group elements as well: $('g').removeClass().addClass('slice'); I came upon this line of code from the removeClass documentation on the jQuery site. Ultimately my desire is to have this Pie Chart of

问题 I have some kind of strange behaviour using jQuery's Click-Function. I also tried it with the on-EventHandler. There is some simple markup from Twitter's Bootstrap Navbar and I'm trying to change the CSS-Class of an li-tag. In this case I want to remove the CSS-Class active and add it to the currently clicked li-tag. But the change get's applied with a shift of one click. So when when e.g. 'Preview' is the current visual active element and I click on 'Document', the CSS-Class seems not to be

问题 I am trying to create a menu where a class "active" is assigned to the page whenever it's selected and loaded. Right now it is applied only to the index page by default. My menu snippet: <ul class="nav navbar-nav"> <li class="active"><a href="http://localhost/wp/index.php">Main</a></li> <li><a href="http://localhost/wp/news">News</a></li> <li><a href="http://localhost/wp/contacts">Contacts</a></li> </ul> 回答1: Try this code. Its working at my end. <script> jQuery(document).ready(function() {

问题 This annoying red line shows up randomly when resizing this component using it's split bar (top edge of component). I did figure out how to remove the red line permanently by removing its CSS class, but there's a catch 22. I'm having a difficult time removing a CSS class in the Sencha ExtJS framework for this Activity1 component. I have a styling issue where the backgroundColor style attribute shows a red line for a very specific layout of containers within that component. The red color is

问题 I've added a class via addClass. I have an onclick function for that added class. However jQuery ignores the click function I created for that class. I've tested it on JSFIDDLE here <style type="text/css"> .openInfo:hover{color:red} .closeInfo:hover{color:blue} </style> <div class="openInfo">OPEN</div> <script> $('.openInfo') //executes correctly .click(function() { $(this).text("CLOSE"); $(this).addClass('closeInfo'); $(this).removeClass('openInfo'); }); $('.closeInfo') //ignored .click
