VueJS has a built-in transition component that needs to be wrapped around the element, which needs transition. There is button called clickme created using which we can change the value of the variable show to true to false and vice versa. There is a p tag which shows the text element only if the variable is true.
We have wrapped the p tag with the transition element as shown in the following piece of code. The name of the transition is fade. VueJS provides some standard classes for transition and the classes are prefixed with the name of the transition. Its the starting state. This is the active state for entire and the class is available during the entire entering phase.
It is removed when the transition is done. This class is used to apply the delay, duration, and easing curve during the leaving phase. Each of the above classes will be prefixed with the name of the transition.
We have given the name of the transition as fade, hence the name of the classes becomes. The opacity property is changed to 0 in 2 seconds. The duration is defined in the. The final stage is defined in the.
Let us consider another example, where there is an image and it is shifted on the x-axis when the button is clicked. The name of the transition is shiftx. A transform property is used to shift the image on the x-axis by px using the following piece of code.
Creating Custom Scroll Directives
On the click of the button, the image will shift px towards the right as shown in the following screenshot. Animations are applied the same way as transition is done. Animation also has classes that needs to be declared for the effect to take place. To apply animation, there are classes same as transition.When using client-side routing, we may want to scroll to top when navigating to a new route, or preserve the scrolling position of history entries just like real page reload does.
Vue-router allows you to achieve these and even better, allows you to completely customize the scroll behavior on route navigation. Note : this feature only works if the browser supports history. This thing is very useful in SPAs Single Page Appsto navigate between for example a long list of items and show item details. We can save current position offsetY in vuex storage, and after back from item details view, we can smoothly back to latest position on the list. The first one is a directive that listens for click events and scrolls to elements, vue-scrollto.
Scrolling to elements was never this easy! It allows to scroll to any element on page, scroll inside any container, customize how scrolling behaves. The solution is for Vue. Multiple options available to adjust, take a look here.

This simply means we are passing a callback function to the document ready event. It's necessary to do this when our code is expecting DOM elements to exist. First we specify which element we are listening to, which in our case is top. The on 'click' is very readable - simple means when the user clicks on the top element. And as before, the anonymous function we create is being passing in as a callback function. So whenever the user clicks on the top element this function will get fired.
Now for the animation. No, I don't know which ones, and it will probably be unnecessary soon if it isn't already. In our case we are passing in only one css property: scrollTop. And since we are scrolling to the top, we'll set scrollTop to 0. Then as the second parameter we're setting the duration to milliseconds or if you're really good at math: 1 second.
This should give us plenty of time to watch our animation. Now suppose we have an element on the page and we want to scroll to the top of it.
We're only interested in top because we want to scroll to the top of this element. Since scrollTop is the position on the page that should land at the top of the window, scrolling to the bottom of the page requires a little bit of math. The position we want to know is the document height - window height.
If you've been experimenting with animating scroll, you've probably noticed that if the scroll distance is small it scrolls very slowly and if the scroll distance is large is scrolls more quickly.
This is because we are specifying a duration for the animation, and it doesn't care about distance. In most cases, when your scroll distance can vary you'll want to normalize the scroll rate. So instead of always passing in for the duration, we want to take our scroll distance into account.
Transitioning state is out of the scope of this article, but it is possible. I could probably be convinced to write that article too, once I take a long nap.
A transition basically works by interpolating the values from state to another. We can do great things with them, but they are rather simple. Here, to there, and back again.
Animations are a bit different in that you can make multiple states occur within one declaration. You can even chain many animations with delays for really complex movement. In terms of tools, both are useful. Think of transitions as a saw and animations as a powersaw. Sometimes you just need to saw one thing and it would be silly to go out and buy really expensive equipment. For other more robust projects, it makes more sense to make the powersaw investment.
The modal shows and hides on a click of a button.

Based on the previous sections, we already know that we might: make a Vue instance with a button, make a child component from that instance, set the data on the state so that it toggles some sort of boolean and add an event handler to show and hide this child component.
We could use v-if or v-show to toggle the visibility. We might even use a slot to pass the button toggle into the modal as well. See the Pen by Sarah Drasner. This will give us a v- prefix for some transition hooks we can use in our CSS.
This is normal CSS, you can pass in cubic-beziers for eases, delays, or specify other properties to transition. Truthfully, this would also work just as well if you placed the transition in these classes on the component classes themselves as a default.
The one reason I do use it on the enter-active and leave-active classes is that I can reuse the same transition for other elements as well, and not run around the codebase applying the same default CSS to each instance.
This works and looks fine for something like opacity.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again.
To use the plugin, simply use the v-chat-scroll directive. If you have a "loading" animation that disappears when you receive a message from an external source, use the scrollonremoved option to ensure the scroll will happen after the element has been removed.
If you want to avoid having smooth scroll in this situation so it instantly scrolls to bottom after loadingbut keep it when new messages come, use the smoothonremoved set to falsewhile being able to keep smooth set to true for later messages. This option only applies if scrollonremoved is set to true.
When not defined behavior defaults to smooth property. You may use the enabled configuration property to control v-chat-scroll. Skip to content.

For vue 1. Easing is done using bezier-easing - A well tested easing micro-library. It even knows when the user interrupts, and doesn't force scrolling that would result in bad UX.
In case you are using the browser version directly including the script on your pageyou can set the defaults with. If you need to customize the scrolling options, you can pass in an object literal to the directive:. The easing to be used when animating.

How to animate scroll in jQuery
A callback function that should be called when scrolling has started. Receives the target element as a parameter. A callback function that should be called when scrolling has ended. A callback function that should be called when scrolling has been aborted by the user user scrolled, clicked etc. Receives the abort event and the target element as parameters.
Easing is calculated using bezier-easing so you can pass your own values into options. If you need to scroll multiple containers simultaneously, you can import the scroller factory directly and create multiple instances. Using the default scrollTo methods allows for only one scroll action at a time for performance reasons.

This works perfectly when you click on the link with some page which is not current. When I click on the link which is already rendered, i. Vue Router assumes there is no state transition. What is the preferred way to scroll up in this case?
I wanted to answer this question to add more to people coming to this question where scroll behaviour isn't working at all. Expanding on the answer from Vitaly Migunov, you can instead add a scrollTo method to the window object directly from the router.
This way you won't need to add the function to every router link. Basically, I think you want to scroll to the top of the page, unless an internal page location is specified e. All of the answers so far would ignore this location parameter, and just scroll to the top anyway. We can check if there is a location parameter using to.
