jQuery和css3滑动显示tooltips工具提示特效

这是一款效果非常酷的jQuery和css3滑动显示tooltips工具提示特效。这个tooltips工具提示插件可以从4个方向打开：右下（默认）、左下、左上和右上。还可以选择3种颜色：绿色（默认）、蓝色和红色。

HTML结构

要创建这个tooltips工具提示效果，你需要使用p标签，这意味着tooltips的内容对搜索引擎是可见的。在页面加载的时候，p标签的内容被用jQuery替换为滑动面板中的内容。

 

  This slideout is going to open to the bottom-right (the default).
 
 
 

  This slideout is going to open to the top-left.
 
 
 

  This slideout is going to open to the top-right.
 

                

如上所示，每一个标签都带有一个style和一个class。当使用jQuery替换滑动面板时，这些属性一起被复制过去。

style属性决定了滑动面板在父元素中的位置，也就是说，滑动面板的位置和p标签的位置是相同的。

class属性是可选的，它为滑动面板提供一些可选参数。你可以旋转打开的方向或是面板的颜色。

CSS样式

下面只列出了滑动面板的样式：

.slideOutTip{
 /* The main wrapping div of the slideout tips */
 position:absolute;
 padding:3px;
 top:0;
 left:0;
 background-color:#111;
 font-size:13px;
 color:white;
 overflow:hidden;
 height:22px;
}
 
.slideOutTip:hover{
 /* Applying a CSS3 outer glow on hover */
 -moz-box-shadow:0 0 1px #999;
 -webkit-box-shadow:0 0 1px #999;
 box-shadow:0 0 1px #999;
}
 
/* The holder for the title and the icon: */
.tipVisible{ cursor:pointer; height:22px; }
 
.tipTitle{
 float:left;
 font-family:'Myriad Pro',Arial, Helvetica, sans-serif;
 font-size:15px;
 font-weight:bold;
 white-space:nowrap;
 line-height:22px;
 padding-right:5px;
}
 
.tipIcon{
 width:20px;
 height:20px;
 float:left;
 background-color:#61b035;
 border:1px solid #70c244;
 margin-right:8px;
 
 /* CSS3 Rounded corners */
 
 -moz-border-radius:1px;
 -webkit-border-radius:1px;
 border-radius:1px;
}
                

开始的时候，tooltips面板只有标题和一个图标是可见的，然后在后面使用jQuery为它们绑定click事件，当用户点击时滑动面板展开。

/* Three color themes */
.green .tipIcon{ background-color:#61b035; border:1px solid #70c244; }
.blue .tipIcon{ background-color:#1078C7; border:1px solid #1e82cd; }
.red .tipIcon{ background-color:#CD3A12; border:1px solid #da421a; }
 
.plusIcon{
 /* The plus icon */
 width:13px;
 height:13px;
 background:url('img/plus.gif') no-repeat center center;
 margin:4px;
 
 /* Defining a CSS3 animation. Currently only works in Chrome and Safari */
 -webkit-transition: -webkit-transform 0.2s linear;
 -moz-transition: -moz-transform 0.2s linear;
 transition: transform 0.2s linear;
}
 
.slideOutTip.isOpened{ z-index:10000; }
 
.slideOutTip.isOpened .plusIcon{
 /* Applying a CSS3 rotation  to the opened slideouts*/
 -moz-transform:rotate(45deg);
 -webkit-transform:rotate(45deg);
 transform:rotate(45deg);
}
 
/* Special rules for the left and top - opening versions */
 
.openLeft .tipIcon{
 /* Floating the title and the icon to the right */
 margin:0 0 0 8px;
 float:right;
}
.openLeft .tipTitle{ float:right; padding:0 0 0 5px; }
.openLeft .slideOutContent{ margin-top:22px; }
.openLeft.openTop .slideOutContent{ margin-top:0; }
 
.slideOutContent{
 /* Hiding the div with the slide out content: */
 display:none;
 padding:10px;
 font-size:11px;
}
 
/* Hiding the original paragraphs if they have not been replaced (JS disabled): */
 
.main > p{ display:none; }
                

滑动面板默认的打开方式是草右下方打开，你可以通过设置openLeft 或openTop 来改变它的打开方式。你也可以通过class来改变图标的颜色。

JAVASCRIPT

当夜幕加载完毕，jQuery循环整个div中的p元素，将它们替换为滑动面板标签。然后根据style和class为滑动面板绑定click事件：

$(document).ready(function(){
 /* The code here is executed on page load */

 /* Replacing all the paragraphs */
 $('.main p').replaceWith(function(){

  /*
   The style, class and title attributes of the p
   are copied to the slideout:
  */

  return '\
  
\
   \
   
\
    
\
    
'+$(this).attr('title')+'
\
   
\
   \
   
\
    
'+$(this).html()+'
\
   
\
  
';
 });

 $('.slideOutTip').each(function(){

  /*
   Implicitly defining the width of the slideouts according to the
   width of its title, because IE fails to calculate it on its own.
  */

  $(this).width(40+$(this).find('.tipTitle').width());
 });

 /* Listening for the click event: */

 $('.tipVisible').bind('click',function(){
  var tip = $(this).parent();

  /* If a open/close animation is in progress, exit the function */
  if(tip.is(':animated'))
   return false;

  if(tip.find('.slideOutContent').css('display') == 'none')
  {
   tip.trigger('slideOut');
  }
  else tip.trigger('slideIn');

 });               
 $('.slideOutTip').bind('slideOut',function(){

 var tip = $(this);
 var slideOut = tip.find('.slideOutContent');

 /* Closing all currently open slideouts: */
 $('.slideOutTip.isOpened').trigger('slideIn');

 /* Executed only the first time the slideout is clicked: */
 if(!tip.data('dataIsSet'))
 {
  tip .data('origWidth',tip.width())
   .data('origHeight',tip.height())
   .data('dataIsSet',true);

  if(tip.hasClass('openTop'))
  {
   /*
    If this slideout opens to the top, instead of the bottom,
    calculate the distance to the bottom and fix the slideout to it.
   */

   tip.css({
    bottom : tip.parent().height()-(tip.position().top+tip.outerHeight()),
    top  : 'auto'
   });

   /*
    Fixing the title to the bottom of the slideout,
    so it is not slid to the top on open:
   */
   tip.find('.tipVisible').css({position:'absolute',bottom:3});

   /*
    Moving the content above the title, so it can
    slide-open to the top:
   */
   tip.find('.slideOutContent').remove().prependTo(tip);
  }

  if(tip.hasClass('openLeft'))
  {
   /*
    If this slideout opens to the left, fix it to the right so
    the left edge can expand without moving the entire div:
   */
   tip.css({
    right : Math.abs(tip.parent().outerWidth()-(tip.position().left+tip.outerWidth())),
    left : 'auto'
   });

   tip.find('.tipVisible').css({position:'absolute',right:3});
  }
 }

 /* Resize the slideout to fit the content, which is then faded into view: */

 tip.addClass('isOpened').animate({
  width : Math.max(slideOut.outerWidth(),tip.data('origWidth')),
  height : slideOut.outerHeight()+tip.data('origHeight')
 },function(){
  slideOut.fadeIn();
 });
 }).bind('slideIn',function(){ // Binding the slideIn event to .slideOutTip
  var tip = $(this);

  /* Hide the content and restore the original size of the slideout: */

  tip.find('.slideOutContent').fadeOut('fast',function(){
   tip.animate({
    width : tip.data('origWidth'),
    height : tip.data('origHeight')
   },function(){
    tip.removeClass('isOpened');
   });
  });

 });

}); /* Closing $(document).ready() */
