addClass and removeClass in jQuery - not removing class

由 拥有回忆 提交于 2019-11-27 04:22:26
问题 I'm trying to do something very simple. Basically I have a clickable div 'hot spot', when you click that it fills the screen and displays some content. I achieved this by simply changing the class of div, removing 'spot' and adding 'grown' and there's a little CSS animation to make it grow. This works fine. The problem is, within this div there is a close_button, which at the moment is just text. I want this to switch the classes back - i.e. remove grown and readd spot. It doesn't do this

问题 I'm using Prettify from Google and Markdown and I want each time I find a pre code added in the markdown textarea to call again the prettyPrint() function.

How to detect class changing by DOMAttrModified

由 我的梦境 提交于 2019-11-26 21:02:01
问题 I need to detect some class changing, i use for this DOMAttrModified, but something is wrong, what? var first_img = $('body').find('li:first').find('img'); first_img.on('DOMAttrModified',function(e){ if (e.attrName === 'class') { if ($(this).hasClass('current-image')) { $(this).removeClass().addClass('previous-image'); } console.log('log'); } }); Thx for advice. 回答1: The immediate problem is that a attrName property isn't part of jQuery's event's object...you need to use e.originalEvent

Check if class already assigned before adding

由 混江龙づ霸主 提交于 2019-11-26 13:04:34
问题 In jQuery, is it recommended to check if a class is already assigned to an element before adding that class? Will it even have any effect at all? For example: <label class=\'foo\'>bar</label> When in doubt if class baz has already been assigned to label , would this be the best approach: var class = \'baz\'; if (!$(\'label\').hasClass(class)) { $(\'label\').addClass(class); } or would this be enough: $(\'label\').addClass(\'baz\'); 回答1: Just call addClass() . jQuery will do the check for you.
