Javascript幻灯片效果onclick [英] Javascript slide effect onclick

问题描述

我想添加一张幻灯片&使用onclick将效果淡化到DIV，使用纯粹的Javascript。

I'd like to add a slide & fade effect to a DIV, with purely Javascript, using "onclick".

代码在这里： http://jsfiddle.net/TCUd5/

必须滑动的DIV有id =pulldown_contents_wrapper。
此DIV包含在SPAN中，也会触发它：

The DIV that has to slide has id="pulldown_contents_wrapper". This DIV is contained in a SPAN, that also triggers it:

<span onclick="toggleUpdatesPulldown(event, this, '4');" style="display: inline-block;" class="updates_pulldown" >
    <div class="pulldown_contents_wrapper" id="pulldown_contents_wrapper">

我认为控制SPAN onclick的JS代码是：

And I think the JS code that controls the SPAN onclick is:

var toggleUpdatesPulldown = function(event, element, user_id) {
  if( element.className=='updates_pulldown' ) {
    element.className= 'updates_pulldown_active';
    showNotifications();
  } else {
    element.className='updates_pulldown';
  }  
}

如果不能用纯JS制作它，你知道我怎么能用Mootools做到这一点？ （*我只想使用纯JS或Mootols框架。）

If it is not possible to make it with pure JS, do you have an idea how could I do it with Mootools? (*I'd like to use only pure JS or the Mootols framework).

我试图实现以下代码：为什么javascript onclick div幻灯片无效？但没有结果。

I have tried to implement the code from: why javascript onclick div slide not working? but with no results.

非常感谢。

我已经成功使用Mootools，但我无法弄清楚如何添加幻灯片和放大器。淡入效果，延迟鼠标输出

I have managed to make it with Mootools, but I can't figure it out how to add a slide & fade effect, and a delay on mouseout

    window.addEvent('domready', function() {
        $('updates_pulldown').addEvents({
          mouseenter: function(){
            $('updates_pulldown').removeClass('updates_pulldown').addClass('updates_pulldown_active')
            $('pulldown_contents_wrapper').set('tween', {
              duration: 1000,
              physics: 'pow:in:out',
              transition: Fx.Transitions.Bounce.easeOut // This could have been also 'bounce:out'
            }).show();
          },
          mouseleave: function(){
            $('pulldown_contents_wrapper').set('tween', {
                duration: 1000,
                delay: 1000,
                }).hide();
            $('updates_pulldown').removeClass('updates_pulldown_active').addClass('updates_pulldown')
          },
        });
    });

  var toggleUpdatesPulldown = function(event, element, user_id) {
      showNotifications();
  }

有什么想法吗？

推荐答案

jQuery 要容易得多，但使用纯JavaScript可以做到这一点。

jQuery is a lot easier, but with pure javascript you can do it.

在CSS中你需要使用过渡

In the CSS you'll need to use transitions

#thing { position:relative;
  top: 0px;
  opacity: 0.8;
  -moz-transition: top 1s linear, opacity 1s linear;
  -webkit-transition: top 1s linear, opacity 1s linear;
 }

然后在javascript中更改元素的位置时，它应该改变通过css过渡。

then in the javascript when you change the position of the element, it should change via the css transitions.

var toggleUpdatesPulldown = function(event, element, user_id) {
  if( element.className=='updates_pulldown' ) {
     element.style.top = someValue; //something like '100px' will slide it down 100px
     element.style.opacity = '1.0'; //will fade the content in from 0.8 opacity to 1.0
     element.className= 'updates_pulldown_active';
    showNotifications();

编辑 - 提供jQuery代码

调用jQuery库，最容易从谷歌主机上完成

call the jQuery library, most easily done from the google hosting

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>

制作悬停功能

$(document).ready(function() {
        $('.updates_pulldown').hover( //first function is mouseon, second is mouseout
            function() {
                $(this).animate({top: '50px'}).animate({opacity: '1.0'});
            },
            function() { //delay 1000 milliseconds, animate both position and opacity
                $(this).delay(1000).animate({top: '0px'}).animate({opacity: '0.5'});
            }
        )
    })

函数时间将与您设置的任何时间相同在带有过渡标签的css中。再次使用'this'而不是类名确保效果仅发生在悬停的类的特定实例上。我不确定这个动画是否正是你所要求的，但如果我正确理解了这个问题，那么主要功能将对你有用。只需更改数字等，以满足您的需求。

the function timing will be the same as whatever you set it to in the css with transition tags. using 'this' instead of the class name again makes sure that the effect only occurs on the specific instance of the class that is hovered over. im not sure if this animation is exactly what you were asking for, but if i understand the question correctly then the main functionality will work for you. just change the numbers and such to fit your needs.
