Question

我有一个评级插件，它可以正常运行并提醒每个评级。但是，除了警报，我需要为每个评级明星显示消息（如果评级为1-Poor，2-Bad，3-Average，4-Good，5-Awesome）。需要在评级明星旁边显示这些消息。

当它被评为3星时，需要显示div（显示一些信息）并在选择其他开始时隐藏相同的div。

当用户费率低于3时，需要提供textbox（.comment div）来输入评论并在评分超过3星时隐藏。

以下是用于评分的代码：

var $me = $( '.star-ctr' );

   var $bg, $fg, step, wd, cc,
       sw, fw, cs, cw, ini;

   $bg = $me.children( 'ul' );
   $fg = $bg.clone().addClass( 'star-fg' ).css( 'width', 0 ).appendTo( $me );
   $bg.addClass( 'star-bg' );

   function initialize() {

      ini = true;

      // How many rating elements
      cc = $bg.children().length;

      // Total width of the bar
      wd = $bg.width();

      // Width of one rating element; assumes all are the
      // same width;  Used if step > cc
      sw = $bg.children().first().outerWidth( true );

      // Width of each star (including spacing)
      fw = wd / cc;
   }

   $me.mousemove(function( e ) {

       if ( !ini ) initialize();

       var dt, nm, nw, ns, ow, vl;

      // Where is the mouse relative to the left
      // side of the bar?
      dt = e.pageX - $me.offset().left;

      // Find the per element step
      vl = nm = Math.floor( dt / fw );
      nw = $fg.children().eq( nm ).position().left;

      ns = Math.round( ( dt - nw ) / sw );
      ow = nw + ns * sw;

      $me.attr( 'data-value', vl );
      $fg.css( 'width', Math.round( ow )+'px' );

   }).click(function() {

       // Grab value
       alert( $( this ).attr( 'data-value' ) );

       return false;
   });

Answer 1

此演示有效，使用数据属性显示评级消息，同时显示和隐藏评论块。

＆＃13;

var 
    // Stars
    stars = $('.stars'),
    star  = stars.find('.star'),
    // Messages
    rating = $('.rating'),
    // 3 star information block
    information = $('.information'),
    // Comment block
    comment = $('.comment');

star.on('click', function() {
  var that  = $(this),
      value = that.data()['rating'];

  // Remove class for selected stars
  stars.find('.-selected').removeClass('-selected');

  // Add class to the selected star and all before
  for (i = 1; i <= value; i++) {
    stars.find('[data-rating="' + i + '"]').addClass('-selected');
  }

  // Show text that explains the rating value
  rating.find('.-visible').removeClass('-visible');
  rating.find('[data-rating="' + value + '"]').addClass('-visible');

  // Show information block if value is 3
  if (value === 3) {
    information.show();
  } else {
    information.hide();
  }

  // Show comments block, if value is 3 or lower
  if (value <= 3) {
    comment.show();
  } else {
    comment.hide();
  }
});

.stars {
  display: inline-block;
  position: relative;
  vertical-align: middle;
  font-size: 3em;
}

.stars ul {

HI现在尝试这个，如果点击评级按钮，而不是在你的js中写下这段代码

var valueData = $( this ).attr( 'data-value' ) ;
       if(valueData => 2){
          if(valueData == 2){
            $('.comment').text('Average');
          } else if(valueData == 3){
            $('.comment').text('Good');
          } else if(valueData == 4){
            $('.comment').text('Awesome');
          }
       }

编辑：小提琴已更新消息

if($( this ).attr( 'data-value' ) <= 2){
    if($( this ).attr( 'data-value' ) < 2){
        $(".comment").append("<br><textarea></textarea>");
    }
    $(".comment").show();
  }
