Fadeout javascript

you tell you mistaken. Not essence..

Fadeout javascript

This is a very straightforward method. If the element is visible and the fadeOut method is called on that element, the element slowly turns transparent until it becomes invisible. This method will fade the element in milliseconds. The value is the default value of the duration parameter. If this argument is not supplied, the default value of milliseconds is applied.

A very important point to note here is that the callback function is called once for each element. It expected another string-typed parameter which would define the type of transition during the animation. So, how does the fadeOut method achieve its goal? Simple answer, it plays with the CSS opacity and display properties of the element. Over the duration of the fading out activity, the opacity of the element is gradually decreased.

Once it reaches zero, the display property is set to none. Higher the duration, the slower is the fading animation. This is the playground for most of the jQuery related concepts. We would be using this playground throughout this article. Now, fire up your browser and go to any websites which are built upon jQuery. Open the developer console.

Next, we identify the element we would like to fade. From the Elements tab in the developer window, you would see that the element is this:. Next, go back to the Elements tab and search for the logo element again.

Notice the addition of CSS display property to the element now.We use fade-in and -out animations on elements to give our users a more pleasant experience when they view our website or app. With jQuery slowly fading out from web development I want to show in this article how to make a fadeIn and fadeOut function in plain javascript. Please note that changing the opacity of an element can also be done purely via CSS3 and if we just need to do that it is the most preferable because most performant solution.

The way how to achieve this with CSS3 would be to either use the. However, with both of these techniques an element that gets faded out still would occupy blank space. It would be invisible but not gone similar to visibility: hidden.

Sometimes we want the element to be gone and not take any space after it is faded out. We want it to be set to display: none. We can achieve this easily with Javascript.

jQuery - fadeOut( speed, [callback] ) Method

Please note that I am using ES6 syntax. If you are not familiar with this please see my es6 article series and keep in mind that it needs to be transpiled to ES5 for older browsers via babel. Afterwards we create another anonymus function that is bound to the variable animation and sets the opacity of our element equal to the result of the value from our previously declared opacity variable plus 0.

I chose 0. Feel free to play with the numbers to make it optimal for your case. You can use console. Once the condition is passed we make sure that opacity is exactly one and cancel our animation frame see next step via the cancelAnimationFrame fn method.

We use requestAnimationFrame for creating the iteration because this way we give the control to the browser when to re-render the layout and not force it on it as we would do with either setTimeout or setInterval. Since the browser is single threaded this intervention could lead to a sluggish experience as other javascript potentially with other animations may need to be executed too. With requestAnimationFrame the browser controls the redrawing of the layout at an eye-friendly approximate 60hz framerate and provides us with a smooth animation that is not conflicting with any other javascript tasks which may run simultaneously.

We assign an anonymus function to our rAf variable that assigns a recursive call to itself via the requestAnimationFrame method. In other words we let the function call itself.

Please be careful when you do recursive calls and always define a condition under which it gets cancelled. We assign the function call to our variable request which we declared earlier. The reason we declared request outside of the rAf function is scope.

We need to be able to access it via the cancelAnimationFrame method from within the animation function. We run animation and alter the opacity of our element on each iteration. Finally we call our rAf function to get it all started.

The fadeOut method is basically an inverted function of our previous explained fadeIn method. I will not go through it in such detail because it is essentially the same as the fadein method just altering the opacity from 1 back to zero and applying display: none in the end right before the iteration gets stopped to leave no blank space behind.

We will use the following timing methods mentioned below and we will be changing the opacity attribute of the image to create a smooth fade in and fade out animation.

The setInterval method calls a function or evaluates an expression at specified intervals in milliseconds. The setInterval method will continue calling the function until clearInterval is called, or the window is closed. The ID value returned by setInterval is used as the parameter for the clearInterval method. The clearInterval method clears a timer set with the setInterval method. Note: Add a image of your choice in your code directory or create a separate directory for images and add it into it and use that location in this code.

In fact, the 'fade to black' effect is so great that Metallica wrote a song about it. A bitmap image is a picture composed of pixels - small, colorful dots.

We will gradually decrease the value of each component of each pixel, which will result in the image fading out to black. Let's take a look at this piece of art which I painstakingly created: You're not seeing anything? Take a closer look! There are actually four pixels just above the word 'You're' : black, white, green and gray. Take a look at how this image information is stored in memory: I zoomed in on the four pixels which are now large squares and showed the corresponding array below.

Each pixel is defined by four values bytes - unsigned integers of 8 bits, but you don't have to remember that. The first three values correspond to the three RGB components. The fourth one is the alpha transparency and we'll ignore it for now. So the first pixel's RGB values are 0,0,0 - it's completely black.

The second pixel is- maximum values for each component, which results in white. The third pixel has a high value of Greenbut lower values of R and B, resulting in a shade of green.

The fourth pixel has equal values of each component, resulting in gray. You can access the values of the Canvas pixels using the getImageData function. In real life you probably want to hide the img element, so that only the fading picture will be visible.

We get each component [] and decrease it if it hasn't reached zero already []. Finally we draw the updated image [27] and request another animation frame [28].

Any animations like fade in, fade out, slide in etc… were done with Jquery. But, now the technology has changed a lot.

The CSS3 properties help us to make the web pages awesome. The fun trick you can do with CSS3 is make your images and other elements fade in and out using the CSS3 properties: opacity and transition. CSS3 help us to make our web pages more interactive by creating greyed out areas that come into focus when a reader mouse over an element.

Inorder to make the fade in fade out effect for any element, the first thing we need to do is change the opacity when a customer is hovering over an element. Here when we hover the image the change is abrupt. These techniques have very good browser support, and so will look reliably good.

The only exception to this is Internet Explorer. You need to use browser prefixes for the other browsers, as indicated above. It does not mean that only fade in fade out is possible with CSS3 animations. We can do a lot of interesting stuffs with CSS3 animation properties.

So, now let us see some interesting tricks with CSS3 animations. With CSS3 we can swap two images on hover of the image. For this we need to add two images in our Html. The following HTML code shows how to add two images for swap image effects. Yes, we are ready to see the magic with CSS3. Before that, let me explain the CSS which we have used.

The CSS which makes one image fully transparent while the other is fully opaque and then the transition swaps the two images when we hover the image container swap-image. So, now we have learned how to make fade in fade out effects with CSS3. Previous Post. Next Post. View Posts.
