將值傳遞給方法選項的更有效/更清晰的方法？

Question

我正在使用jquery.barRating.js對呈現給我的頁面的每個div元素進行評分。

我必須爲每個div呈現以下html ..目前有四個呈現。

<div class="star-ratings"> 
       <p>Rate This Video</p> 
       <div class="stars stars-example-fontawesome-o"> 
       <select class="example-fontawesome-o" name="rating" data-current-rating="" autocomplete="off"> 
        <option value=""></option> 
        <option value="1">1</option> 
        .......... 
       </select> 
       <span class="title current-rating"> 
        Current rating: <span class="value">5</span> 
       </span> 
       <span class="title your-rating hidden"> 
        Your rating: <span class="value"></span>&nbsp; 
        <a href="#" class="clear-rating"><i class="fa fa-times-circle"></i></a> 
       </span> 
       </div> 
      </div> 

各級別選擇是通過下面的腳本，它接受一個選項initialRating啓動 - 這是告訴腳本衆多明星應該如何高亮顯示，十分之。

var arrOfRatings = [5,4,6,7]; 

$('.example-fontawesome-o').each(function (i, obj) { // Each instance of .example-fontawesome-o 

    $(obj).barrating({ 
     theme: 'fontawesome-stars-o', 
     showSelectedRating: false, 
     initialRating: parseFloat(arrOfRatings[i]), // Array set up earlier with ratings in 
     onSelect: function (value, text) { 

      var starRatingSelector = $(this)[0].$elem.parent().parent(); // div.stars.stars-example-fontawesome-o 
      var starRatingChildCurrentRating = starRatingSelector.children('.current-rating'); // .stars.stars-example-fontawesome-o span.title.current-rating.hidden 
      var starRatingChildYourRating = starRatingSelector.children('.your-rating'); // .stars.stars-example-fontawesome-o span.title.your-rating.hidden 


      if (!value) { 
       obj.barrating('clear'); // Clear rating if there was a problem 
      } else { 

       starRatingChildCurrentRating.addClass('hidden'); 


       starRatingChildYourRating.removeClass('hidden') 
         .find('span') 
         .html(value); 
      } 

     }, 
     onClear: function (value, text) { 
      console.log($(this)); 
      var clearSelector = $(this)[0].$elem.parent().parent(); 


      clearSelector.children('.current-rating') 
        .removeClass('hidden') 
        .end() 
        .find('.your-rating') 
        .addClass('hidden'); 
     } 
    }); 


}); 

該評級是在上面的HTML -

<span class="title current-rating"> 
         Current rating: <span class="value">5</span> 
        </span> 

但此刻，我有我在其中也必須給予通入選項的評級數組來傳遞。 initialRating: parseFloat(arrOfRatings[i])

我不得不做這種方式，因爲我不能訪問$（本），直到腳本不會越過以下

$(obj).barrating({ 
     theme: 'fontawesome-stars-o', 
     showSelectedRating: false, 
     initialRating: parseFloat(arrOfRatings[i]), 
     onSelect: function (value, text) { // Can only access $(this) here} 

所以在清除總之我不知道是否有一種方式來獲得值<span class="value">5</span>中的值爲5，並將其傳遞給initialRating而不用於額外的數組？

假設子元素的次序順序相匹配的數組中，並與類current-rating的唯一元素是你需要的，你可以使用

initialRating: parseFloat($('.current-rating').eq(i).find('.value').text()),
