我有一个超长的 jquery 片段，我觉得可以用正确的逻辑来简化它。我害怕碰它，因为我终于让它工作了。

“else $target = #none”实际上是一个“什么都不显示”的声明。我不确定如何以更好的方式表达这一点。

$(["CO;CO1", "CO;CO2", "CO;CO3", "CA;CA1", "CA;CA2", "CA;CA3"]).each(function() {

      var data = this.split(";");
      var id = data[1];
      var region = data[0];

      var $target  = $("#" + id);
      if ( mmjsRegion == region ){
        $target = $("#" + id);
      }
      else{
          $target = $('#none');
        }

      $target.imBannerRotater({
        return_type: 'json',
        data_map: {
          image_name: 'name',
          url_name: 'url'
        },
        image_url: 'http://www.kindreviews.com/wp-content/plugins/geoads/' + id + '.php',
        base_path: 'http://www.kindreviews.com/wp-content/plugins/geoads/images/',
      });

});

我看不出这是什么原因。。

var $target  = $('#CO1');
      if ( mmjsRegion == 'CO' ){
        $target = $('#CO1');
      }
      else{
          $target = $('#none');
        }

对，我认为这可以归结为：

(function($) {
    $.each(['CO1', 'CO2', 'CO3', 'CA1', 'CA2', 'CA3'], function(index, id) {
        $('#' + (mmjsRegion == id.replace(/\d+$/,'') ? id : 'none')).imBannerRotater({
            return_type: 'json',
            data_map: {
                image_name: 'name',
                url_name: 'url'
            },
            image_url: 'http://www.kindreviews.com/wp-content/plugins/geoads/' + id + '.php',
            base_path: 'http://www.kindreviews.com/wp-content/plugins/geoads/images/',
        });
    });
})(jQuery);

由于mmjsRegion在代码期间没有改变，它可能会下降更多，但我不知道该imBannerRotate()插件是否应该被调用$('#none')三次，看起来像一个黑客。如果$('#none')不需要，则可以是：

(function($) {
    $.each(['1', '2', '3'], function(index, id) {
        $('#' + mmjsRegion + id).imBannerRotater({
            return_type: 'json',
            data_map: {
                image_name: 'name',
                url_name: 'url'
            },
            image_url: 'http://www.kindreviews.com/wp-content/plugins/geoads/' + mmjsRegion + id + '.php',
            base_path: 'http://www.kindreviews.com/wp-content/plugins/geoads/images/',
        });
    });
})(jQuery);

$(function(){

    var targets = ['CO', 'CA'];
    var iterations = 3;

    $.each(targets, function(index, value){

        for(var i=1; i<=iterations; i++)
        {
            var targetId = '#' + value + i.toString();
            $target = $(targetId);

            if (mmjsRegion == value) {
                $target = $(targetId);
            } else {
                $target = $('#none');
            }

            $target.imBannerRotater({
                return_type: 'json',
                data_map: {
                    image_name: 'name',
                    url_name: 'url'
                },
                image_url: 'http://www.kindreviews.com/wp-content/plugins/geoads/' + value + i.toString() + '.php',
                base_path: 'http://www.kindreviews.com/wp-content/plugins/geoads/images/'
            });

        }
    });
});

这应该这样做：

var r = mmjsRegion,
    s = r == 'CO' ? '#CO1, #CO2, #CO3' : r == 'CA' ? '#CA1, #CA2, #CA3' : '';

$(s).each(function() {
    $(this).imBannerRotater({
        return_type: 'json',
        data_map: {
            image_name: 'name',
            url_name: 'url'
        },
        image_url: 'http://www.kindreviews.com/wp-content/plugins/geoads/' + this.id + '.php',
        base_path: 'http://www.kindreviews.com/wp-content/plugins/geoads/images/',
    });
});
