fadein

问题 Is there a way to get a fade-in/-out animation on a canvas rectangle background in kivy? I tried it by using the Clock.schedule_interval() function. But several problems occured concerning concurrency and data raise. One of my tries looks as follows: def calendarClicked(self, *args): self.alpha = 1.0 self.alphaDelta = 0.01 self.root.canvas.add(Color(1,0,0,self.alpha)) self.root.canvas.add(Rectangle(size=self.root.size)) def fadeIn(self, dt): self.alpha -= self.alphaDelta self.root.canvas.add

问题 How can I get my images to appear one after the other? I am currently using Jquery fadein to make my images fadein but I want them to start at different times.

问题 This might seem as child play, but I can't figure out how I can replace the src attribute of an image. The src is "build.php" which generate the image. What I want is when I click on "mix" it will run build.php to generate a new image, remove the old image and display the new image with a nice fadeout/fadein. Also with an "Building new image" which hides when the new image is done loading. I tried with $("#mix").click(function(){ var img = new Image(); $(img).load(function () { $(this).hide()

问题 I have a problem with fadeIn() refusing to work after hide() or fadeOut(). I am trying to toggle a div (#content) with a fade animation.

I'll try to describe how the error occurs: 1st Step: fadeIn() (works) $('.popup a').click(function(){ $("#content").css("background-color", "#DDD").fadeIn(200); // works, display changes to block $('#content').children().fadeIn(600, function(){ $("#content").animate({

问题 I want to use only three methods from the jquery library without importing the whole library in my file, so is there any way to extract only fadeIn(), fadeOut(), load() from jquery? 回答1: You could look at the source code and try to remove anything not required for the fadeIn and fadeOut methods, but you would likely end up with most of the library. Overall jQuery is not designed to be taken ala cart, it is designed to be a single small footprint library. If it is not small enough for you

问题 I'm using Flexslider to animate a series of rolling slides. It's in and working just fine. What I'm now wanting to do is make use of the 'after:' callback to fadeIn the headline within the slide. In terms of a run order it would look something like this: Slide (containing a background image) fades in. Pause (1 second). Headline fades in.

问题 Hey guys, I am trying to make a magnifying glass background when the use hovers over an image that can be enlarged. This is using a blank span and setting its display to none until it is hovered, and having its background be a semi-transparent png with a magnifying glass in the center. This is done using fadeIn / fadeOut and works perfectly in all of the other browsers besides IE. In IE, the background of the image flashes to dark gray before fading to the correct image on hover and hover out
