【超酷超实用】CSS3可滑动跳转的分页插件制作教程

浏览数：17 / 时间：2015年06月09日

今天我要向大家分享一款很特别的CSS3分页插件，这款分页插件不仅可以点击分页按钮来实现分页，而且可以滑动滑杆来实现任意页面的跳转，看看都非常酷，很适合一些个性化的个人网站使用，当然，这款分页插件也适合ajax翻页，效果都挺不错的。先来看看效果图：

怎么样，还挺酷的吧。

当然你也可以在这里查看插件的DEMO演示。

接下来我们来分享一下源码的实现思路，这里用到了jQuery UI框架，这么酷的滑杆是靠它实现的，不然，写的累死。。

首先是HTML代码：

<div class="pageSlider long"></div>

    <form class="pageForm" action="#">

      <label class="pageLabel" for="pageInput">
        Page number you‘d like to go to. (Max of 30)
      </label>

       <a 
      class="pagePrev pageSkip" 
      href="#?page=6" 
      title="Previous Page (6)">Previous Page</a>

      <input id="pageInput" class="pageInput" 
      type="text" maxlength="3" placeholder="#">

      <a 
      class="pageNext pageSkip" 
      href="#?page=8" 
      title="Next Page (8)">Next Page</a>

      <button class="pageButton" 
      title="Go to chosen page of results">Go</button>

    </form>

这里我们看到，先是定义了滑杆的区域，然后是两个分页按钮，可以向前翻和向后翻，最后是一个任意页跳转的页码输入框和一个按钮。

别看这个滑杆很漂亮，会很难实现，其实利用jQuery UI这个东西非常简单。

接下来看看CSS代码：

前后翻页按钮：

.pageSkip {
  display: inline-block;
  background: transparent url(‘css/monotone_arrow_left_small.png‘) no-repeat -10px -10px;
  text-indent: -999em;
  background-size: 40px;
  opacity: 0.7;
  vertical-align: middle;
  width: 20px;
  height: 20px;
}
.pageNext {
  background-image: url(‘css/monotone_arrow_right.png‘);
}

很遗憾，利用了两张箭头图片作为背景，不过，效果也还可以。

然后是输入框：

.pageNumber {
  position: relative;
  top: -38px;
  left: 50%;
  font-size: 12px;
  color: #333;
  width: 60px;
  display: block;
  text-align: center;
  margin-left: -17px;
  background: white;
  padding: 5px 10px;
  border-radius: 3px;
  box-shadow: 0 0 5px rgba(151, 38, 20, 0.15);
}
.pageNumber:after {
  content: " ";
  display: block;
  position: absolute;
  width: 0;
  height: 0;
  top: 24px;
  border: 6px solid transparent;
  border-top-color: white;
}

然后是滑杆的背景，利用了CSS3线性渐变属性：

.ui-slider-horizontal {
  width: 60%;
  height: 6px;
  top: 0px;
  margin: 0px 10px 2px;
  border-radius: 6px;
  position: relative;
  display: inline-block;
  background: #F46652;
  background-image: repeating-linear-gradient(28deg, transparent, transparent 10px, #dd5846 10px, #dd5846 20px);
  box-shadow: inset 0 2px 5px rgba(0, 0, 0, 0.4);
}
.ui-slider-horizontal:before {
  content: " ";
  position: absolute;
  width: auto;
  height: 16px;
  top: -5px;
  left: -4px;
  right: -4px;
  border-radius: 10px;
  z-index: -1;
  background: linear-gradient(rgba(0, 0, 0, 0.1) 0%, rgba(255, 255, 255, 0.8) 90%);
}
.ui-slider.long .ui-slider-handle {
  height: 12px;
  width: 30px;
  background: #f1f1f1;
  display: block;
  position: absolute;
  border-radius: 50px;
  margin-top: -3px;
  margin-left: -15px;
  text-decoration: none;
  background: #f5f5f5;
  background: linear-gradient(#f5f5f5 0%, #cccccc 100%);
  box-shadow: 0 0 10px 0px rgba(0, 0, 0, 0.35), 0 0 2px 1px rgba(0, 0, 0, 0.15), 0 3px 3px rgba(0, 0, 0, 0.2), 0 7px 5px rgba(0, 0, 0, 0.1), 0 11px 10px rgba(0, 0, 0, 0.1);
}
.ui-slider.long .ui-slider-handle::before,
.ui-slider.long .ui-slider-handle::after {
  content: " ";
  width: 2px;
  height: 40%;
  position: absolute;
  background: transparent;
  border-radius: 0px;
  box-shadow: -1px 0px 0px rgba(255, 255, 255, 0.8), 1px 0px 0px rgba(255, 255, 255, 0.8), 2px 0 0 rgba(0, 0, 0, 0.3), 1px 0 0 rgba(0, 0, 0, 0.3) inset;
}
.ui-slider.long .ui-slider-handle::before {
  left: 10px;
  top: 30%;
}
.ui-slider.long .ui-slider-handle::after {
  right: 12px;
  top: 30%;
}
@media (max-width: 550px) {
  .pagination {
    width: auto;
  }
  .pageForm {
    display: block;
    margin-top: 20px;
  }
  .pageInput {
    margin: 0;
  }
  .pageSlider {
    width: 260px;
    margin: 0 15px;
  }
}

最后是js，这是用来实现翻页逻辑的，来看看：

$(document).ready( function() {
  
  

  var pagesMax = 30;
  var pagesMin = 1;
  var startPage = 7;
  var url = "http://yoursite.com/results?page={{1}}";
  
  $(‘.pagination .pageSlider‘).slider({

    value: startPage, max: pagesMax, min: pagesMin,
    animate: true,
    
    create: function( event, ui ) {
      
      $(‘.pagination .pageSlider .ui-slider-handle‘).attr({
        "aria-valuenow": startPage,
        "aria-valuetext": "Page " + startPage,
        "role": "slider",
        "aria-valuemin": pagesMin,
        "aria-valuemax": pagesMax,
        "aria-describedby": "pageSliderDescription" 
      });
       
      $(‘.pagination .pageInput‘).val( startPage );

    }
  
  }).on( ‘slide‘, function(event,ui) {
      
      // let user skip 10 pages with keyboard ;)
      if( event.metaKey || event.ctrlKey ) {
        
        if( ui.value > $(this).slider(‘value‘) ) {
          
          if( ui.value+9 < pagesMax ) { ui.value+=9; } 
          else { ui.value=pagesMax }
          $(this).slider(‘value‘,ui.value);
        
        } else {
          
          if( ui.value-9 > pagesMin ) { ui.value-=9; } 
          else { ui.value=pagesMin }
          $(this).slider(‘value‘,ui.value);
          
        }
        
        event.preventDefault();
        
      }
      
      $(‘.pagination .pageNumber span‘).text( ui.value );
      $(‘.pagination .pageInput‘).val( ui.value );
      
  }).on(‘slidechange‘, function(event, ui) {
    
      $(‘.pagination .pageNumber‘)
        .attr(‘role‘,‘alert‘)
        .find(‘span‘)
        .text( ui.value );
    
      $(‘.pagination .pageInput‘).val( ui.value );
      
      $(‘.pagination .pageSlider .ui-slider-handle‘).attr({
        "aria-valuenow": ui.value,
        "aria-valuetext": "Page " + ui.value 
      });
    
  });




$(‘.pagination .pageSlider .ui-slider-handle‘).on( ‘keyup‘ , function(e) {
  
  if( e.which == 13 ) {
    var curPage = $(‘.pagination .pageSlider‘).slider(‘value‘);
    alert( ‘we would now send you to: ‘ + url.replace( /{{.}}/ , curPage ));
  }
  
});


$(‘.pagination .pageInput‘).on( ‘change‘ , function(e) {
  $(‘.pagination .pageSlider‘).slider( ‘value‘, $(this).val() );
});

  
  
  var tmr;
  $(‘.pageSkip‘).on(‘click‘, function(e) {
    
    e.preventDefault();
    
    var $this = $(this);
    
    if( $this.hasClass(‘pageNext‘) ) {
      var curPage = $(‘.pagination .pageSlider‘).slider(‘value‘)+1;
    } else if( $this.hasClass(‘pagePrev‘) ) {
      var curPage = $(‘.pagination .pageSlider‘).slider(‘value‘)-1;
    }
    
    $(‘.pagination .pageSlider‘).slider(‘value‘,curPage);
    
    clearTimeout(tmr);
    tmr = setTimeout( function() {
      alert( ‘we would now send you to: ‘ + url.replace( /{{.}}/ , curPage ));
    },1000);
    
  });
  
 

function sliderPips( min, max ) {
  
  var pips = max-min;
  var $pagination = $(‘.pagination .pageSlider‘);
 
  for( i=0; i<=pips; i++ ) {

    var s = $(‘<span class="pagePip"/>‘).css({ 
      left: ‘‘ + (100/pips)*i + ‘%‘ 
    });
    
    $pagination.append( s );

  }
  
  var minPip = $(‘<span class="pageMinPip">‘+min+‘</span>‘);
  var maxPip = $(‘<span class="pageMaxPip">‘+max+‘</span>‘);
  $pagination.prepend( minPip, maxPip );
  
};sliderPips( pagesMin, pagesMax );
 

function sliderLabel() {
  $(‘.pagination .ui-slider-handle‘).append(
    ‘<span class="pageNumber">Page <span>‘ + 
    $(‘.pagination .pageSlider‘).slider(‘value‘) + 
    ‘</span></span>‘);
};sliderLabel();


  
  $(‘.pagination .pageButton‘).on(‘click‘, function(e) {

    e.preventDefault();
    var curPage = $(‘.pagination .pageSlider‘).slider(‘value‘);
    alert( ‘we would now send you to: ‘ + 
          url.replace( /{{.}}/ , curPage ));
  
  });
  

});
